I would like to upgrade either my integer Apple II or Apple II Plus with
lowercase, but they are both old motherboards, Rev 4 and Rev 3,
respectively. I have a Videx Videoterm in each, but I'd like to get
lowercase in 40 columns too if practical.
I know that there are three components to be modified for lowercase:
- Monitor firmware that folds input to uppercase
- keyboard encoder
- character generator
For the keyboard, my research uncovered the following options:
- single wire shift key mod
- aftermarket keyboard
- replace encoder board with Videx Enhancer ][
- modify Apple encoder with DPDT switch
And for the display with the character generator I found two options:
- Dan Paymar
- Lazer Lowercase Plus
Right now I can do the single wire shift key mod and I can also solder on
the additional switch to the keyboard encoder. All the other options require
parts that I don't have.
Anyone else have input on this, particularly on getting lowercase display in
40 columns on a pre-Rev 7 machine? Where should I start looking?

I used the Paymar lower case ROM with the shift key mod for a few years.
How well it suits your needs depends on the applications you use and their
support of the shift key mod.
The 5x7 character matrix doesn't support true descenders, but you'll adapt
to that pretty easily.

Thanks. What modification did you use for the keyboard/encoder?

None, just the shift key mod.

I should clarify. I only wanted lower case for word processing, and the app
handled the shift key mod natively.
The Paymar LC adapter EPROM came with a short page 3 program that hooked
into KSW to allow lower case entry, but it wasn't very useful for apps that
didn't expect lower case--like Applesoft.

Thanks. Now I have to look around and see where I can get one of these.
Otherwise I may just have to make do with a shift key mod and Videx 80
columns lower case.

I have two or three home-made Lower-Case Adapters without EPROMs that I made way back in my Apple II Plus days. I also have documentation for these and Dan Paymar's LCAs. And, I have an AP64E EPROM Writer Card. But, I don't remember how to use any of it. I have not used my Enhanced Apple IIe for 21 years. Email me if you are interested in getting one of my LCAs.

James,
Is there a chance that you're THE Jim Davis who wrote the 65C02 Disassembler
in UltraMacros that was published on one of the AppleWorks's disk magazines?
I recall that man as having been from California.
If so, I must say that I was blown away by that disassembler at the time. In
fact, I took a stab at decompiling it to see just how it worked but time got
away from me and I never got very far.
Finally, assuming you're the author, could you still find the commented
source code for that? I'd really love to see it.
Thanks.

I just ordered a UV eraser, EPROM programmer and a bunch of 2716 chips so I will be able to burn my own lower case chips and others...
If you have a rev 7 or newer mobo all you really need is a 2716 burned with the right lower case chip image. I think if you have a pre-rev 7 board you need an adapter socket.
Some ][+ keyboard encoder boards have solder pads for a toggle switch to switch between caps lock and lower case mode. I have soldered a switch on before and it works well, albeit it is a little clunky compared to a real caps lock key and you have to run w/o the top cover to switch it on the fly.

That's interesting. I have enough II+ machines with no power light cover that it might be worth attempting a 'capslock key' mod on at least one of them.
Backburnered. I can hear the purists crying out in pain ... Don't worry, it's a loong way down my backburner ;-)

Jim,
Thanks for taking the time to respond to my inquiry about the authorship of
the 65C02 disassembler written in UltraMacros.
I must say that you sound quite accomplished, nonetheless. :-)

An interesting idea. I have a caps lock keyswitch in a dead //e's keyboard I could use for that kind of hack.
The old ][+ that I used to have I had wired a switch onto a long set of wires so I could run it outside the case and switch between caps and lock... But that was still a little klunky. Your idea would be a little nicer.

Thanks for the tip. As I mentioned in my first post I only have old,
pre-rev7 boards, so I'll look and see if it's possible to use an adapter.
Otherwise I'll need to rig up some switch between two 2513 chips: one with
lowercase, the other upper.

Checkout my "Apple II Plus Hardware Modifications.zip" that I recently uploaded to Asimov <ftp://public.asimov.net/pub/apple_II/incoming> when it becomes available. But, what it does not contain is info about how I mounted my switches underneath the keyboard. If you remove the plastic cover (with the keyboard in it) from the bottom metal chassis, then about one inch up from the bottom bend on the 45-degree angled part of the chassis, draw a line all the way across, parallel to the bend, and you can drill 1/4-inch holes (about 1 inch apart) anywhere along the line to mount micro-switches through. You could pre-drill holes all the way across for future use, too. If you don't use them they will just help with ventilation, keeping your Apple II cooler.

I confess that I was not the one who sent the shareware fee, but in my
(albeit poor) defense, I wasn't really interested in the program from a
user's perspective (I had moved on to IIGS's at that point and used the
'Visit Monitor' CDA for disassemblies from within AppleWorks), but
rather my interest was from the perspective of 'How in the *^!! did Jim
Davis program a 65C02 disassembler in UltraMacros'?

Well, you probably 'Locked' the macro set, but that hurdle was fairly
easy to clear if you had enough knowledge of Ultra, and I did. The
problem, of course, for snoops like I was (am), is that the listings
were devoid of labels, comments, and human order, and so were inferior
to the original source code AWP file containing the macros. It's really
the same issue many of us have now when we disassemble 65C02 code and
have to decipher the program logic and make our own comments and labels.

Number me among the interested should you ever do that.
BTW, considering inflation, I should probably send you a check for $20.
Is your address still the same? But, your programming technique (source
code) is what fascinated me, not the program itself.

Looks like your Zip file got truncated. Here is the message I get when I use
unzip:

Hi DF,
That is not the wrong zip file. Asimov renamed the file I sent early yesterday morning. You will find it here:
ftp://public.asimov.net/pub/apple_II/documentation/hardware/ misc/Lowercase Modifications.zip
My zip files are created by the "7-Zip File Manager" program. I do not know if they will work in an Apple II. They may be to large to fit. They work in Windows 7 on my PC. The file above is 22 megabytes. The one you tried to open is 16.2 megabytes. That is probably too big for an Apple II. You will need to open the files on a modern PC.

Are you using an Apple II? My zip files are created by the "7-Zip File Manager" program. I do not know if they will work in an Apple II. They may be to large to fit. They work in Windows 7 on my PC. The file above is 22 megabytes. The one you tried to open is 16.2 megabytes. That is probably too big for an Apple II. You will need to open the zip file on a modern PC to extract the files it contains. Individually, they may be small enough to view on an Apple II, if you can view PDF documents on an Apple II, that is.

Yes, the information about me that you posted is still good. I still live in the same place and have the same phone number. (If anyone calls, they need to leave a message, because I screen my calls. Say something about the Apple II or Beagle Buddy #227 and I may pickup the phone. Do not send text or voice messages, because I am still using a land-line telephone. I do not use any wireless communications devices.)

That was the key piece of information. These are .7z files. There's no
extractor that I'm aware of for this format on Apple II. I extracted them on
a Mac instead.
Thanks.

I just made the shift key mod earlier this afternoon after a trip to Radio
Shack (who are closing, so everything was from 20 to 50% off!). Works fine
with the Videx 80 card. I put it in the Apple II Plus. This is so simple to
make; I'll make another one for the integer Apple II.
I also bought a DPDT switch at the shack that I guessed would fit, but now I
see it won't fit in the holes on the encoder board. :-(
I should have read this first:
http://apple-crapple.blogspot.com/2016/02/apple-ii-developme nt.html
I merely managed to find a switch that perfectly fits the Apple II keyboard
encoder for enabling lowercase once the character ROM is updated. It is
labeled "ONLEDA MTS-202" and is a knock-off of some old high-quality switch,
I'm sure. Good ebay search terms : Right DPDT toggle switch. Just take note
of how the pins are oriented to make sure you get the right ones. I'm
putting mine away for a rainy day.

I just put a couple feet of wire on the switch I had on my ][+ back in the day... that way I could hang it out the back and flip the switch without having to pop the cover open. That way any old DPDT switch works. I used one I salvaged from some old dead radio if I remember right.

Yeah, I was wondering how inconvenient it would be to have this switch under
the case. I'll hold off on doing anything on it for now. Wendell Sander says
he (via Mike Willegal) has an extra 2513 chip with a lowercase character set
that he could send to me.

The "*.zip" files I made with 7-Zip (v.16.04) are NOT "*.7z" files they are real LZMA-compressed "*.zip" files.
From the 7-Zip Help:
Supported formats
------------------------------------------------------------ ----------
[Chart omitted.--JPD]
ZIP
7-Zip creates ZIP compatible archives.
7-Zip supports the following ZIP compression methods:
0 - Store <--[I believe this is what Windows 7 does; that it is just a folder, that is not compressed, with a dot zip extension added.--JPD]
1 - Shrink (decompression only)
6 - Implode (decompression only)
8 - Deflate <--[I believe this is also what Windows 7 does; that it is just a folder, with some of its files compressed a little bit, with a dot zip extension added.--JPD]
9 - Deflate64
12 - BZip2
14 - LZMA <--[This has the most compression that is supposed to be Apple/ShrinkIt compatible. LZMA is the compression method I used to make the files uploaded to Asimov. It is also Windows 7 compatible. With 7-Zip you cannot choose between LZMA1 or LZMA2; it makes the choice during compression. OK, I see the problem: The dictionary and word sizes (16MB & 32-bits) are too big for an Apple II (a 64KB, 8-bit machine, the minimums for 7-Zip LZMA).--JPD]
95 - xz (decompression only)
98 - PPMd
99 - WinZip AES
Files compressed with other ZIP compression methods can't be extracted by the current version of the 7-Zip. But these supported methods are the most popular today, and therefore 7-Zip can decompress most ZIP archives. To extract files compressed with non-supported methods you must use some other ZIP utility.
7-Zip supports the Zip64 extension of ZIP format.
LZH
7-Zip supports LZH archives only for listing, browsing and decompressing. 7-Zip supports -lh0-, -lh4-, -lh5-, -lh6- and -lh7- methods.

Yes and no. There are some instances of files in 7z-compressed .zip
archives that are unzippable by InfoZIP (Win32, 5.52) because they are
using a too-old PK-Zip format. For example:
Archive: "Upload for Asimov From Beagle Buddy 227.zip"
skipping: Asimov-7.zip = Compressed (zipped) Source-Files Folder.txt
need PK compat. v6.3 (can do v2.1)

So, are you saying that even if I fix the dictionary and word sizes (16MB & 32-bits) that are too big for an Apple II (a 64KB, 8-bit machine, the minimums for 7-Zip LZMA) by reducing them to the 7-Zip LZMA minimums (64KB, 8-bits), and keep Zip files as small as possible, an Apple II running Shrink-It, cannot access them? I would think that Shrink-It is using an even older version of PK-Zip format than what you said (v6.3 or v2.1 {which one?}). Or, are you just talking about InfoZIP (Win32, 5.52)?

Jim,
Well, that's disappointing, but very understandable. It has been 20
years since the mid-90's when guys like you, Wally Bradford, Christian
Serreau, Barclay Clemesha, Daniel Lurot, Bud Simrin, the mystery man
'CUB' and a few notable others were pushing the envelope on what could
be done with UltraMacros and with AppleWorks 5.1 (and who were not named
Randy Brandt, Dan Verkade or Doug Gum).

What say ye to this? -- I'll mail you my personal check for an
inflation-adjusted shareware payment of $20 for your TimeOut
Disassembler, and if you ever come across the source code, you'll have
my address and you can make a copy and send it my way? If not, that's
OK, and you can remember me as just the 'second' guy who paid the
shareware fee for your program, but did it 20 years late.
Just so you know -- I never really _used_ it, but was struck with what
it took you to code it in UltraMacros. Very clever. So very clever.
Similarly, if you have some AppleWorks/UltraMacros related projects on
floppies that you'd like imaged, consider mailing them to me and I can
image them for you and send you something back in a modern format that
you can use with an Apple II emulator.
My interest was always (and still is) with AppleWorks. I'm sure some of
the other guys here would love to image your more general Apple II
floppies if you're so inclined.
I'm still working to make a living, so my time ends up getting rationed
when it comes to things like this. ;-)

Hugh Hood

Unzipping on an Apple II is not practical for the sorts of things you're
talking about, so that part is irrelevant. The message above came
directly from the latest version of InfoZIP attempting to uncompress the
stated file, which is simply complaining about the compression method
used by 7zip on one of the components of that zip file. If you could
simply avoid using 7zip, that would make your uploads more universally
consumable.

I have researched InfoZIP and found:
The message is because InfoZIP uses the deflate compression method exclusively. It cannot use any higher methods--like LZMA. Its "Zip" program either deflates a file, or it does not, simply adding the file as is (uncompressed). Its "UnZip" program either inflates deflated files, or it does not, simply extracting the file as is (uncompressed). Higher compression methods cause it to output an error message and skip the offending file.

There is nothing wrong with 7-Zip! Limiting it to Deflate compression method is all that is needed for InfoZIP to decompress zip files 7-Zip creates.
The dictionary and word sizes have nothing to do with the zip files made; these parameters are only about the capabilities of the computer the 7-Zip program is running on. I have been experimenting with different dictionary and word sizes and the zip files created are all identical.
All that is needed is that the Asimov Sys-Ops unzip uploaded zip files and redistribute their contents into their site categories accordingly. (The only reason to zip is to achieve faster uploads and to minimize bytes uploaded. Unfortunately, you cannot achieve faster downloads, and minimize bytes, when zip files are unzipped and their files placed elsewhere.)
