I'm sure you'll have fun with all your finds, but this is the one that
caught my eye.
Last week (?) someone was asking questions along the lines of what the
heck does one do with an IBM 3278?
The answer is, plug it into this. Neither is much use without the
other! I suggest the two of you get together over this...
The 3274 is called a "terminal controller". It is not per se a
computer, although I think it may have had microprocessors and things in
it. The floppy drives were for saving and loading configuration data
(along the lines of Port 1 a 3278, port 2 is a 3299 with 8 3278s hung
off it, port 3 is a printer etc...) It multiplexes terminals and things
to an IBM mainframe channel. While the 3278 and its relatives use the
IBM SNA protocol over 93 ohm co-ax, the 3274 can AFAIK connect over an
ordinary serial line. In which case all you need to do is write drivers
for whatever machine you choose as the host...
Happy hacking!

As I recall you wanted some sort of justification and I really
couldn't think of anything beyond "yeah, I'd like to get a look at
that" -- really I figured you would find other respondents who could
offer it better homes. I do have some 6800 stuff (not Sphere, Smoke
Signal Broadcasting) but also have the manuals for it and probably have
a book or two around somewhere with the 6800 instruction set.
I guess it's time for one of those questions I still don't have a good
answer for. Where the foo has all the SS-50 stuff gone? Or is it still
hiding? Or is it just not here in Sillycon Valley?
I have a couple of SS-50 systems in my collection. Depending on how
you look at it, the SSB Chieftain may be the system that started me off
collecting, though I really bought it with the idea that it was all
put together out of commonly-available parts that I could replace if
I let the magic smoke out while teaching myself hardware hackery.
(I never got the appropriate round tuit, and am still lacking a
proper appreciation of electronics.)
Oh, and it was another few years before I finally admitted to myself
that what I was about was collecting old computers. You know, the
first step to recovery is admitting you have a problem....[1]
And, well, last week I saw the first SS-50 stuff I've seen up for
grabs since I moved to Sillycon Valley seven-plus years ago. I
recognized it as SS-50 at a distance, but it had already been
stripped: all that was there was the chassis and power supply, with
the motherboard, baud rate generator, and a couple of serial cards.
All Gimix stuff but that's all that was there of it. Even the front
plate from the case was missing.
Well, I left it there.[2] When I went back for it today I got there a
little bit past closing time. I expect it's still there, and will go
back for it again on Monday.

[1] "Well, I've filled this storage closet...I guess I'm gonna have
to rent another one." Somehow I don't think this is the sort
of "admitting I have a problem" that will lead to recovery.
[2] No, I won't write about why I did that. Suffice it to say I
felt pressed for time, and when I think about the time my
colleague in this endeavor wasted before and after I am *still*
seeing a little red.[3]
[3] Insert a smiley after every third word if you think that helps.
I have several switched power supplies from IBM clones that I would like
to try to repair, can anyone suggest a source of a book or schematics for
these things?
Thanks

I have an 820-II with all manuals and docs, unfortuneately it is not
working ( the
harddisk controller or harddisk has gone south!) If you need any
information from the manuals, please let me know I will be glad to
oblige. Also have a ton of CPM software that came with it, so if you
need bootdisks or the like I can help there too.
Would you friend like to sell his harddisk controller card and drive
perhaps?

Well there is a company that sells them new for 30.00 so..... so much for
any inflation beyond that. If anyone wants that link let me know.

I just got the voicemail of one of my contacts at Apple which said that the
Apple Library was "permanently closed." There was a pretty decent
collection of Apple hardware in that room, among other things. The good
side is that Jane Oros, the head librarian, is a very responsible person
(and I have a call in to her now.) The non-good side is that, as we know,
Apple is now in the hands of senior management who are convinced that the
history of their company is nothing but a drag on their energies.
I would appreciate hearing from anybody on this list who is also an Apple
employee and can say more about pertinent current events there. Any other
discussion also welcome, of course. TIA!

If you find one that cheap, I'd like one. I only have a TS1500. Any other
sinclair you can find for that price or accesories, and I would gladly
reimurse you for shipping as well.
zx81, TS100, TS2048, TS2068, 2050 modem with case, or just case, {have the
modem already} Any printer that works....

You might care to try the Apple II archive FTP site at:
ftp://ftp.apple.asimov.net/pub/apple_II/
This site has documentation, FAQs, disk images of almost everything that
is/was available for the Apple II series of computers, including a section
for educational software.
cheers,
John

A church with which I work was recently given an Apple IIGS (with "Woz"
signature on the front, I notice).
Does anyone have any children's educational software for Apple that he/she
would be willing to donate or sell cheaply? You can get tax credit if you
want.
Please e-mail me -- manney(a)nwohio.com -- or contact the church directly:

Thanks -- you'll be doing inner city kids a great favor.

"Un sot trouve toujours un plus sot qui l'admire."
The keyboard plugs into the back of the MegaPixel display, then the
display is attached to the cube. The A and B ports are the serial ports.
They are wierd old ones that, on the 68040 boards are compatible with
standard Mac serial cable, though I am not sure if they support hardware
flow control. check NeXT Answers at http://www.next.com/ for more
detailed info, and pinouts.
The removeable cartridge drive is most likely meant for a 230M
Magneto-Optical disks of the 5.5" variety. They are somewhat hard to
find nowadays. Try looking at http://www.deepspacetech.com/ They have
tons of old NeXT stuff, and I believe they have these disks.
Another nice feature of these machines, is that they know how to handle
removeable media and both DOS and HFS volumes. This means that you can
plug a Zip drive into the SCSI port and transfer downloaded files to the
NeXT until you get it up and running on the Net itself.
The following URL is a terrific archive of NeXT software.
ftp://ftp.peanuts.org/next/
Enjoy it. It's a great machine.

Peter Washburn

I'd guess that those 15-pin connectors are the serial ports. If you
don't turn up the pinout, holler, I have an adapter cable at the
office (used to use it to hook an HP 700/22 to one) and could ohm it
out one of these days (i.e. it'll go on my copious free time list for
when I find where I packed the cable when we re-carpeted the offices
a few weeks back).
