Hi CSA2,

I have a 2e which is great with it's SSC comms card, but my 2GS is lacking ability to talk to the outside world in the same respect. I'd rather not have to buy a whole new SSC and a whole new set of cables, when there's a perfectly good communications adapter built right into the machine, but I cannot for the life of me find a 2GS (is that DIN-8) to DB9 connector.

The following website was no luck, mainly dead links. The ones which were live seem to not stock such a cable.
http://apple2.org.za/gswv/a2zine/faqs/Csa2T1TCOM.html#025

I also tried retrofloppy, but at a whopping $75 USD to ship to New Zealand, for a $19 cable, the words daylight and robbery seem appropriate here.

So does anyone know where I can purchase said cable at a reasonable rate, preferably in NZ/AUS?

Cheers,

Alistair

Way back when, I made my own cable according to the diagram in the ProTERM
manual. Go to page 284 here:

http://lostclassics.apple2.info/wp-content/files/InTrec/InTr ec_A2-PT31.pdf

To connect to another computer, you'd only need to add in a null-modem
adapter and maybe a gender changer and/or 25-to-9-pin adapter, both of which
I'd think are still available off-the-shelf.

For an off-the-shelf cable option, try finding a Mac modem cable (though
there might've been some minor differences between this and what the ProTERM
manual recommends). Hardware handshaking is preferred. Combine with the
aforementioned gender changer and/or 25-to-9-pin adapter and you should be
good to go.

I just wanted to add to this that after I sent this to CSA2, I sent an email to
David at Retrofloppy.

He was able to bring down the cost of shipping from $75 to $46.50 which is a
good effort, unfortunately still a bit to much for my personal budget, however I
was impressed with his customer service and willingness to try to assist, so I'd
recommend retrofloppy, especially if you are in the USA as postage inland US was
only $5 when I tried a Boston ZIP code.

I've sent some stuff overseas from America and IMO, a $19 computer cable
shouldn't cost too much more than $19 to ship. I wouldn't even use a rigid
box, since I'd imagine you could wrap it up really nicely in an envelope.

It does fit nicely in an envelope. A padded one, even. Take a look at
pricing for Priority Mail Express International envelope from US to NZ -
it's $46.50 at the post office. ($42.75 online.) Priority Mail
International is cheaper - $24.75/$23.50. But the problem with Priority
Mail International is that it's not trackable, and there's no proof of
delivery. So if/when the package gets lost, sender loses the cable, the
money for the cable, _and_ the money for the postage - since PayPal
won't/can't verify it ever went anywhere. Trust me, it's happened so
enough times to me I won't ship anything without proof of delivery. I
feel bad that everyone not on my continent has to suffer, but I am not
left with a lot of choices.

So, yes, you can send a first-class international envelope for
$9.15/$8.60. At least that way sender loses less in postage cost when
they go missing...

I was able to purchase the 8 pin DIN and 9 pin serial plugs from Jaycar Electronics for a few bucks.

Here is how I wired it up:-
http://lukazi.blogspot.com.au/2012/01/waltr-introduction.htm l

However the pins on the 8 pin DIN are very close together so it was a bitch to wire up. If I was to do it again I would just purchase a cable (go to ebay and search for 'mac 8 din'), cut it to the required length and then just wire in the 9 pin serial to it.

Hope that helps.


Alex.

Hand-soldering a mini-DIN is cruel and unusual punishment. Heck, even a
regular DIN can try ones patience. Cutting a double-ended cable in half is
absolutely the way to go. D-shell connectors are easy to solder and you get
two cables out of it.

Seconded.

Sometimes I just don't feel like making a cable. Lazy.

8-din to DB9 and I think Bill Garber may be able to come to the rescue so I'm
incredibly indebted to him if he can indeed help me out.

If not, then I guess I'll try and get a 8-din from USA somewhere and try your
suggestion Alex.

Thanks all!

8-pin mini din plugs with crimp-on terminals are likely available
locally, same with DB-9 plugs. Just strip the wire, crimp on the pin and
insert into the socket.
