Hi.
I have two WANG WLTC laptops, two Tandy 1400HD's, and I used to have a
Toshiba T3100/20 and a T1200. They all had the same type of HD connector.
The Tandy's have 20MB ALPS drives, and the WANG's have 10MB JVC drives, and
the Toshiba's had 20MB JVC drives. I have NEVER been able to find
replacement drives with this same connector. It's a 26 pin connector.
Even though I don't need them, I'd like to have a few spares.
ThAnX,

Yes, it is. Or better it is a semi cusom chip - like ASICs today.
The Basic design is a standard compilation of TTL functions, only
the last metal layer is custom. This was an early attempt by some
chip manufacturers to cut design costs - only this last layer had
to be designed for every customer. The technic was(is) called ULA
Unassigned(?) Logic Array. And thats also the name used by ZX-fans
for this Chip.
The ULA replaces something like 15 or 20 standard TTL bugs from the
ZX-80 design - the 81 is just a ZX-80 II :)

P.S.: Don't assemble it ... I assembled 5 kits several years ago -
and now I could cry for one :(

Definately. I have seen you on the classicmp mailing list. Sorry about
sounding like a bonehead with the PDP/11 boot problem. It's not my bag.

How long was the C64 sitting in the basement? It could be that the key
contacts are corroded. It happened to me once on a TRS-80. The key
wouldn't type, but if I'd pound on it for a while, it would type, but then
keep typing until I pounded it again. I took the keyboard apart, took the
cap off of the key, and then cleaned the contacts with alcohol. It worked
fine after that. It doesn't sound like it would be bad, since if something
was dead, probably the whole top line wouldn't work - or at least more than
4 keys.

That's what I figured. Not worth any more than I paid for it? Hmm... That
makes it worth absolutely
nothing :-). Oh well, guess I'll just use it as soon as I get the power
supply fixed.

Digi-Key has them.
Part number: A2096-ND
Go to http://www.digikey.com and do a Part Search for the above part
number. Just make sure the mount spacing between the connector back edge
and the solder pins on the Atari port is the same as in the Digi-Key
specs. Anything different could cost a lot more for a replacement
connector with a non-standard mount spacing. The sample PDF page of the
catalog entry is available online. Pictures and details of the part are
available there. You need Acrobat reader to view the catalog page.

Yes, they have a website, the only thing it's good for really is
directions to the store and a phone number.

I was just given a Mac, which doesn't seem to have a hard drive or software.
Does anyone have an O/S he (she) would wish to get rid of cheap(ly), plus an
app or two?
I'm presuming my DOS 3.3 won't work. <g>
Thanks,

Ooooh expensive :)

Hmm if it is only about this keys, it cant be a dead line.
But for C64 it is still about to throw the unit away - (I
just hauled 12 C64 from a school today) they are $5 thingis.
Or store it as spare part (and they are worth about USD 50
as replacement parts). I wouls sugest a rapair only if it
is about a special unti of personal history/interest.

hmm, sounds like the exact size of an Xterminal that I have somewhere
that uses an '88k CPU. Let me know if you grab it an get it working,
>from what I remember if it's the same as mine it needs boot images on
the server off which it hangs in order to run - the ROMs only have
enough info to boot the network system. If it is the same machine, it'll
take standard 72 pin SIMMS and an IBM PC keyboard (with a PS/2 style
connector). Memory's hazy, but I think it had a custom 15-pin connector
at the back, but it threw out standard frequencies that could be used
with a Sun workstation monitor...
I did find some info on the web for the box, it's possible I have it at
home - just give me a shout...
As for things using '88k's, My old Tektronix XD88 Unix box also used one
as it's main CPU. I think they're supposed to be a lot better chips than
68k's, just that they never really caught on - 68k's were too well
established (and therefore a lot cheaper).
