I've got a 10mhz IBM AT With a display (I don't remember if mono or color...I have plenty of each) for the taking.
I think it's got at least 640k in it, but may have 512k.
I know it has a Hard Drive. Not sure what size.
It has a 1.2gb FDD.
I don't have an IBM keyboard for it. But I can dig up something compatible.
It's for free... so whaddya want?
You can also have an original IBM Graphics Printer to go with it. (Epson MX-80 Rebranded). I'm sure I can dig up a printer cable too.
It's located in N.E. Philadelphia, PA
E-Mail me off list.

I sent Dave about a dozen MB tests that I did on various MBs recently.
There was one case where 1.2MB 500k DD failed, but read/wrote in DOS.

I'm not sure if Al has it on bitsavers or not. I have a couple original
handbooks for the computer lab and a copy of the teacher's guide.

That can be arranged. I have the old calendar printing program and
several nudes to choose from. :-)

While conversing with another list member about some old components, I was
reminded of hearing somewhere that there was a nasty failure mode of
the LM309K 5V regulator (it being the (or one of the) first integrated 5V
regs) which might make it somewhat undesirable for current use.
I don't want to declare that there is such a problem - it's a vague
second-hand rumour to me - so can anyone confirm or elaborate on this?
I've never personally run across problems with them..
A 76 Moto databook indicates it has those nice things like short-circuit
protection and thermal-overload protection.. ..another device perhaps?
Hola, collectors!
I just got home from VCF East 4.0
of course I?m biased, but what a
great weekend!
Around ? of the exhibitors came Friday night afternoon/evening to get
ready. This year we expanded the venue from one room to two. But, the
second room is still VERY under construction. Some of our volunteers
were literally still installing sheetrock that morning. So we had to
use some yellow caution tape, but it added character. :-)
Friday night was bar trip #1
I drove back to my hotel safely was but
very, very tired waking up early Saturday.
For Chuck Peddle?s videocon Saturday morning, the weakest part of our
internet connection was the wifi
or so I thought! Turns out, the wifi
worked great, as did Skype. Chuck spoke to us for an hour+
then he got
an strong round of applause
then we were about to begin audience Q&A.
All was fine until that part. Until our videocon server went BSOD!! We
couldn?t even get it to reboot in ?safe mode?
so we emailed Chuck from
my cell phone, who said he had to get going anyway, but that anyone with
questions could email him. Okay then!
Bil Herb, Bob, Russell, and Dave Haynie took their turns next; lots more
great stories and they brought many prototypes to show us, including the
famous Commodore LCD. They even hung around out exhibit hall after the
panel and after some chocolate chickenhead cake. One of them, Haynie,
joined us for the official VCF Dinner that night.
Speaking of dinner: the bill was $555.58. If only someone hadn?t drank
that last three cents of beer
!
Today was just as much fun. We had how-to lectures, we learned the
history of CPM, we heard all about Jeri E.?s toy-making experiences and
there?s a picture of someone posing next to our museum?s chip
collection. Meanwhile the collecting guru Sellam told some secrets
which I?m not going to share here
except for this one: when pushing an
8-foot-tall rack, be alert for unstable monitors on top. (Hopefully
there won?t be a scar.)
My LEAST favorite part of any VCF is tearing down at the end of the
weekend. But it had to be done. To ease out of the weekend while
keeping out good mood, I went to dinner with Hans and Sellam, had a few
beers, and
well it?s been a while since I drank three nights in a row.
Anyway, the show was terrific. Peddle?s unique hour-long lecture,
20-ish exhibits, attendance in the triple figures, and we even gave a
few museum tours. Heck, one guy came all the way from New Zealand.
Pics and hopefully some video will be posted soon.

I don't know this drive by model number, but IIRC it's a daul 5.25"
drive with an HPIB interface. I have an HP drive that fits that
description, unfortunately I can't get to it quickly, so I can't verify
the model number, but I do remember some things about it.
Can you post a picture of the controller card somewhere? I may have a spare one laying around here (somewhere).

Tony, many thanks - the schematics/circuit diagrams appear to be 100%
relevant to my board. I can now start trying to figure out what I zapped.
It looks like the -50 and -30 suffixes are little more than cosmetic changes
or switch configurations. My FDD is also a half height.
I was thinking about the Z0765A FDC and how to make it compatible with a
300rpm FDD. It seems that all that needs to be done (in theory) is to
reduce all the FDC clocks by half - the 8MHz clock to 4MHz and the Write
Clock to 500KHz. (NEC indicates this in their uPD 765A datasheet). Clearly
not as simple to execute as it sounds, but not beyond the realms of
possibility.
Thanks to everyone else who responded.
Peter
