Retro computing and gaming, sci-fi books, tv and movies and other geeky stuff.8-Bit Designs "STATUS" Update!
https://www.megalextoria.com/forum2/index.php?t=rview&goto=167918&th=65572#msg_167918
the Power Pro 250 Power Supplies, and The Ultimate Gamepad's; they have
been cancelled due to my inability to reach a "reasonable" deal with
anyone from this group.
As such, BOTH DESIGNS have been returned to the former owner in an
agreement to complete the TOTAL TRANSFER of all the other "assets" that
I currently maintain and will continue to maintain in the future.
Thus, The Power Pro 250 and The Ultimate Gamepad will NOT BE PRODUCED
BY ME! I still have the catalogs on CD for anyone that wishes to
acquire one of all the other products and services that I still perform
for those of you that might be interested.
In conclusion, I would like to thank all that participated in the
"offers" that I extended, to all the Commodore users in The World
(PAST, PRESENT, & FUTURE), and would like to extend my ETERNAL
GRATITUDE TO BOTH MICHAEL HUNTER (for designing the products and then
selling them to Mr. Springle so that I could acquire them), and to
DENARD SPRINGLE HIMSELF for offering these wonderful peoducts to me
which allows me to pass them on to community at large.
Again, THANKS A LOT EVERYONE,
and MAY GOD BLESS AND KEEP YOU ALL!!!!!

As Charles has already mentioned I will reacquire the rights to the
PowerPro 250 and the Ultimate Game Pad and release him from any further
obligation to me for the rights to those products.
At this juncture I am unsure what I intend to do with the designs to
be honest with you. After reading how wonderfully receptive everyone
has been to the sale of these rights I obviously will not attempt to
resell them. I understand that it's been a couple years since these
products were actually produced due to circumstances beyond everyone's
control and that good intentions really don't mean much to this
particular group - results do. Perfectly understandable.
At the same time, however, the audacity some of you have to poke,
prod and flame the very people who want to be a part of this community,
and especially those who propose to design and develop products that
would be of benefit to the community as a whole, leaves me unwilling to
simply release the designs into the Public Domain. Those people
seriously drive down the value of this group and of the community as a
whole. I've said it before and I'll say it again - this group routinely
drives away everyone who wants to be a part of the community failing to
realize that *everyone* has *something* to contribute regardless of
their level of knowledge or expertise on any given subject.
So, let us open up a new discussion on the topic then...
Convince me that releasing these designs to public domain would be
of benefit to the community as a whole. Convince me that you would in
any way appreciate having the ability to build these products for
yourselves and each other. Convince me that you're truly interested in
the community and not just out for yourselves and for whatever freebies
you can get your hands on. Convince me that you're a group of people
capable of understanding and compassion for others. Convince me that
you want this community to thrive and flourish, that you're capable and
willing to help others in this community instead of flaming everyone
who makes the mistake of posting in comp.sys.cbm.
How do you do this? Simple. Tell me how having these designs would
benefit you or someone you know in this community. Tell me that you'd
be willing to improve the designs and release them to public domain.
Tell me that you'd love to have either of these products if someone
would just make them or tell you how to make them yourselves. Convince
me.
If you can do that, then I will release them into public domain and
publish them on my website for all to enjoy and benefit from.
Flame me, and I'll bury the designs and be done with it.
The decision is in the hands of the members of this community -
let's see how many of you really care about the community, and how many
of you would deprive everyone else in the community of the benfits of
having these designs available in the public domain.
-- Denny
And yes, this *is* a perverse attempt to get those people of this
community who find it best to discourage and flame everyone who posts
here to check themselves at the door, to bite their tongues, to be open
and receptive to others in the community and to offer help, assistance,
praise and support. Will it work? Place your bets folks, place your
bets.]]>c64diehards2006-08-31T19:52:51-00:00Re: 8-Bit Designs "STATUS" Update!

If I may say something: this is the wrong forum to post such articles to.
Most people who actually _do_ something are already far away, on other
forums, with a lot less, _registered_ members and, possibly, moderation.
These can be Web-based forums, mailing lists, internal newsgroups on
personal servers etc...
With Google Groups having made the UseNet NEWS available for all kinds
of people via the common Web interface, the signal/noise ratio became
almost unbearable. People who did remain here are newbies, people willing
to help newbies, a few people making announcements here (as well), and...
well... those people you already talked about. I haven't seen serious
discussions here for months (years?). Bye,
Joe

'freeware' status for hardware or public domain.
First off, the PowerPro 250 was essentially by all means 100% based on a
project that someone in the community did some years ago. Was it Greg Nacu?
We are talking about - say, 1990s. It was all derived from the earlier AT
Powrer Supply for C64. Using the 5v lines. This is ALREADY public domain
tech before 8-Bit Designs even existed. I have to do some historical
research but this goes back for some time. The ONLY ip that maybe of any
merit of uniqueness is the "Ultimate GamePad". I would pay for the IP of
that but lets be realistic.... not overly priced Denard. However, I would
likely put it into PD myself, so I really recommend that be put to public
domain as well.
There is no practical sense for commercial development for classic Commodore
hardware in a traditional sense. Don't hold onto the IP as if it is
meritable for a patent. It's not! Release the designs to public and offer to
sell pre-manufactured units for those who would want one already made. Do it
in that fashion. Don't try to run it like a 'BUSINESS'. Run it like a nice
friend willing to make it for the costs plus a small amount and
shipping&handling.
Use Jim Brain's model. If someone pays him for the parts and all, he'll make
them on a order by order basis but the instructions and designs are
available for those who can make it themselves. I know that you spent alot
of money on this and you guys shouldn't have spent more than $5,000 but
still needless to say, it is another matter altogether BUT lets just be
realistic. What are special of the design. If I were to request it from
people that I know, I can get the designs from other PlayStation gamepads
for C64 and ultimately figure out exactly how Michael Hunter did it. Mostly
using the poteonomitor (spelling is likely incorrect) line used for the game
paddles for the directional pad and some sort of DACs used to convert key
combos into analog signals and some buttons into analog values and so on and
so on. So if you decode the digital values and the analog values, you will
get some special values... Anyway, I do have the docs on the programming the
unit so that in itself will give a person enough clues to reverse engineer
the sucker. There is the X,Y axis and the buttons. Once you know how the PSX
gamepads works in itself, you can make it do whatever you want. So with
enough clues, and some hw knowledge, we can reverse engineer and make a new
unit without EVER seeing the actual finished unit or its schematics and have
it run 100% the same. (Especially if you have one of those exact model of
Playstation gamepads. (I do, got it from Michael Hunter, before being
converted over). Thus, if I opened it up and traced the line signals, I will
know for sure, how it works. (Need a few LED to light up the data lines or
just look up standard Playstation gamepad docs. They all work basically th
same... with exceptions to 4 and 8-Dir Pads. (Probably similar C64, NES,
SNES, flag both the X and Y lines accordingly.) Whatever, it don't matter.
It can be solved, pure, plain and simple.

I can't really speak to the PowerPro being 100% based on somebody elses
work, though knowing what I know about 8-Bit I wouldn't doubt if this
were 100% true ;)

Heh... I never claimed it was :) And I'm not holding onto it for profit
potential anyway.
As for what is special about them? Not much I suppose - these designs
can surely be reverse engineered from an existing one, or built from
scratch with a little knowledge of electronics. :)
My point was, until I read Joe's post, that it would be fruitless to
release these to the public domain for people who aren't in this
community to be a part of the community - but the signal/noise ratio
issue Joe raised nullifies that somewhat...]]>c64diehards2006-08-31T22:40:30-00:00Re: 8-Bit Designs "STATUS" Update!

This is from someone who:
1. Uses Google Mail for E-mails.
2. Uses Google Groups to access UseNet NEWS.
3. Mixes me up with Wildstar and some person named Forest.
Thanks for further validating what I said, in a remarkably precise way!

yeah, it sure can. Little bit of hw knowledge and clear understanding of the
joystick port in both hardware and software level and clear understanding of
the lines going to the connector on a Playstation connector would give
enough clues as to how Michael Hunter wired it to the DACs and the pins to
the pins. It basically goes from the pad down the wire to some little
electronic micro gizmo and then to the 9-pin port. The micro gizo basically
a DAC and some wiring work. Once I find were I have the docs are Programming
the Ultimate GamePad.

Just release it to public - hence you are releasing it to this community.
Put up a website and the information. Simple? Don't worry about the
'fruitfulness'. It will be as fruitful to the community as good as the
product is. If it is a good product and design, people will make 'em, or buy
'em. If you are willing to make complete units if someone wants one, cool.
If they want to make them, fine. Those interested in making games could then
apply it to their game design. It would be cool. Leave it up to the
community. By releasing it to public, is by all means releasing it to the
community. Simple.
If we like to take advantage of it, cool. If not, oh well. The knowledge is
still there. It just makes it easier for us... that's all.]]>rick balkins[1][2]2006-08-31T23:53:00-00:00Re: 8-Bit Designs "STATUS" Update!

Only because a lot of garbage comes from Google users, doesn't mean
that every user of Google's services only produces garbage. I don't
know much about Dragos, but he seems a serious collector and user
and I've already made business with him.
Personally, I'm just about as bothered about people posting under

several of the flakes of the scene.
it has been pointed out to me that perhaps i lashed out too quick.
sometimes it happens, I am human.
Possibly *someone* cares about the power supply,m but as it hasn't been
available for years, was VERY over priced and there are tones of
duplicate plans out there, I was hoping to get rid of the, what I like
to call, The Springle element.
If he were really gone, and rams well would actually either DO
something or pipe down. Then we could *maybe* get some uise out of
this group. I know, wnaderer would still be around, but he is sporadic.
anyways, The loss of these "designs" is no real loss. If you want a
custom power supply, contact eslapion from the Denial Vic-20 forums.
He built me a sweet one for very cheap, I use it every day.

Hmmm... I like that... kinda cachy - 'The Springle Element'. Can I use
that? Seriously.
I know many of you don't like me - that's cool though... happens to the
best of us. But frankly, I've never actually been gone. I don't
participate much - I use and enjoy my Commodore machines for what they
are - a whole lot of fun in a cute little box - but I'm always around.
Doesn't really matter what you think of me or if you like me or not -
very few of you even know me so... oh well! :)
Granted, I made the mistake once of thinking that I could buy 8-Bit and
jump right into production of Michael's designs in addition to my own
and turn it into a small (very small) return as a business, but that
just didn't pan out. Can you blame a guy for trying? Apparently so :)
The PowerPro 250 is actually a very nice design by comparison to some
of the others I've seen - even those produced and sold overseas. At no
point did I claim that this particular design was in any way unique nor
original, not even when Michael built them.
The Ultimate Game Pad is also not an original design... if you guys
knew your Commodore history you'd know that in the mid 90's there were
a couple different commercially available models of the 'game pad'
design. A change here, a change there and viola! Ultimate Game Pad.
Nothing special.
The value of these designs is in them actually being built by somebody
- that's the real value and where they are best served as business
assets, if they were to be anything. As several people have pointed
out, that hasn't happened for a couple of years and at this point most
folks could care less about them. I have never said that either of
these designs are unique or special in any way - they are merely an
implementation of knowledge readily available or easily figured out by
those with the knowledge and capability. If you need to send either one
of these to China to have them reverse engineered, then you wouldn't be
capable of building one in the first place and should probably think
about finding someone else to build one.
In any case, I already planned to release these to Public Domain and
host the designs on my website heh... I just wanted to see how many of
you would jump in and try to bash me :) Death, taxes, and getting
flamed on comp.sys.cbm are certainties for sure ;)]]>c64diehards2006-09-01T14:56:34-00:00Public Domain hardware designs

I'm waiting on the return of these designs and their accompanying parts
at the moment and once I receive them back I'll go ahead and post the
designs on my site and offer the parts in my store. In the meantime, a
synopsis of the designs follows:
PowerPro 250
------------
The PP250 is a modified AT/ATX power supply which can be built to power
your Commodore 64/128 and associated drives, printers, et al. with a
single unit. The '250' in the original design was due to the use of a
250 Watt power supply, though I have successfully built several of
these using different wattages with equally impressive results.
So, what is it? As you may have already gathered the Commodore 64/128
(and anything else with a VIC or VIC-II in it) uses 5v DC, 12v DC and
9v AC. Most peripherals use 5v DC and 12v DC. AT/ATX power supplies
provide a steady stream of 5v and 12v (and often other voltages
depending on the model -5v, -12v and 3.3v DC are also popular in modern
supplies). With the addition of a 9V AC 1Amp (or better) transformer
(the VIC/II requires a steady current of 1 Amp of 9v AC to operate
correctly - otherwise black screen of death occurs). In addition to
adding the 9v AC transformer, however, a (rather large, 25W - TO-220
package) resistor is driven between 5v and Gnd and heatsinked. Why? If
you have any of those 'other' power supplies built overseas you'll
notice the 50/60hz 'Hum' in your video and sound... this is due to a
lack of noise filtering. The other reason the resistor is there is to
prevent spikes from destroying your hardware when switching the power
on and off. To complete the design, fuses are added and (if required)
the 110/220v switch is disabled (this was due to the 9v AC transformer
Michael was using only accepted 110v AC on it's inputs - if you can
find one that supports 110 & 220 there is no need to disable this
switch). It's a very basic synopsis. The original video created by
Michael Hunter will be available for download from my website once I
get it back from Charles which walks you through how he built them. I
will note my design changes on the website as well as alternate
configurations.
Ultimate Game Pad
-----------------
The Ultimate Game Pad is a PS1 controller modified to provide specific
paddle input voltages via resistors soldered between the pads and the
X/Y ports. It is a very simple design, and is cheap and easy to build.
Complete instructions along with the schematic and programs will be
available once I get everything back.
I'll post again here once everything is back together and posted to my
site.

Yes and no -- the C-64 (and IIRC, the C-128 as well) as a unit needs
only 5 V DC and 9 V AC. The 12 V DC supply is generated internally from
the AC supply.

Not "often" -- this has nothing to do with "popularity". It's in the
standard.

So you're using a *resistor* for noise filtering? How is that supposed
to work? That's what capacitors are for...
Besides: AT/ATX supplies are switched supplies. There should be little
50/60 Hz noise; most noise should be at the switching frequency.
The only reason for a resistor in that place would be that ATX supplies
need not work below a certain minimum output current (1A @ 5VDC, IIRC),
and the resistor is there to provide that minimal load -- choosing a
supply that does not require that load would, however, be a smarter
choice.
