Yeah? Which make/model? If it *were* Adaptec, I'd bet it's an ACB-4000,
in which case it's MFM<->SCSI (sortof). What sort of machine is it
going into?

I have been looking all over for the model number of a fancy digital fm
tuner that heathkit made about 1978. It was unusual because it had a keypad
on it to punch in the station you wanted. Is it possible for you to look in
your 1978 heathkit catalog and see if such a thing is in there. If you
could put it on your site it would be great!
Thanks,
Sam Lowenstein

I will agree here as well. You will find that most "museums" may show the
computer, but probably not running, and you can't get a hands on feel for it.
Also many older machines can still be providing usefull services for people
but won't do that sitting in any museum. You can come and see my :museum"
pieces anytime , and I'll even let ya "touch" them :-)

Deer Sir;
I have just been given three ENIAC machines to display in a museum but they
are currently in Nigeria where they were used for nuclear weapons testing.
I can get them and preserve them for the National Museum of Science but I
need your help. They won't believe I am a serious collector unless I can
show them that I own a working PDP-1. I need you to box up and ship me a
working PDP-1 so that I can set it up and show it to them. Then they will
send me the three ENIACs by first class air mail. I will keep one, send one
to the museum and you can keep one. You will agree that an ENIAC, the first
digital computer, is much more valuable than a PDP-1 so you will understand
that I must keep the PDP-1 just in case they do a "surprise" inspection.
Thank you for your help, it is a good cause.
Sincerely,
Prof. Peabody.

Sound like a PDP-8/I Core stack. I think it was an OEM part supplied by
digital. They seemed to use several different manufactures. The one I
have in front of me is Core Memories LTD Dublin Ireland.

leading to white handles on top left).

That's possibly the RLL version of the same card; ACB-4070.
These were used alot on fileservers in the mid-80's (although,
I must admit I've never seen one with a 3.5" formfactor).
Oh yeah, there's also an ACB-55xx series, this family
was more diverse: They made a model that could do
SMD<->SCSI, f'rinstance. I have one of these, but it doesn't
work.
These were all *partial* SCSI implementations. The
*real* scsi boards were the ACB-4520/25's. These were
for ESDI drives, though.

Got prompted with a nice Windows checkbox today while upgrading an NT
workstation to Service Pack 6a...it said:
"Always trust content from Microsoft Corporation?"
Yeah right....that little choice remained unchecked...

The board is from Sun Remarketing and is labled as being manufactured by
them. It is in an Apple Lisa and converts the signals from the external
parallel port to those of the MFM drive. The converter and hard disk are
mounted directly above the floppy drive internally with a ribbon cable going
out the back of the case to the external port. I'll look at it again when I
get home and post specifics on it. Unfortunately, I don't have any
documentation on the hard disk setup.
I've had a few of the Adaptec boards, including one mounted in an Atari
SH-204 hard disk, converting from the ST's interface to the MFM drive
mounted in the enclosure.
Jeff
I have here an ISA card labelled "APPLE TURNOVER" on the lower inner part
of the board (on the inside of the edge connector" and "(C) 1984 VERTEX".
It has what looks to be a standard floppy edge connector/pin connector
(either can be used).
I'm thinking (and hoping) this is a card that allows one to read Apple ][
floppies with a standard PC drive on the PC.
Anyone ever heard of this? Am I right? Does it require software? If so,
anyone got it?

Yup, that's exactly what VP was for, and IMHO it did it way better than
the current set of tools for the masses (Office etc). It kept you well
away from the guts of the machine, there wasn't a command line option
at all - everything that was locally installed was somewhere in the
"Directory" icon, which you opened up and used the click-COPY-click
mouse action to put it on your desktop to use. Piece of cake.

Absolutely, if you were a developer you'd almost never use VP unless
you had to put together a fancy-looking presentation or report for the
boss :-) All my development work was done in the Tajo (XDE) environment
where I had access to a command line (well, as many as I wanted), file
tool, editor, and the usual slew of compiler/binder/debugger tools. On
top of that there was a hefty fileserver somewhere on the West Coast where
we could get hold of the "Hacks" tools. Lovely :)

There isn't much difference between my T2 running POS and a Dbox running
XDE, they have the same basic set of tools and utils. Obviously the PERQ
tools are for Pascal and the Dbox's are for Mesa, and the PERQ UI looks
like an XDE Executive full-screened :-) Heck, even the directory names
follow the "{volume}<top>sub>file.ext" format :-)

Ha ha, Word goes to the sad people who occasionally ask me to put stuff
together for them. They can only handle Word, and the customer is always
right ;-) Emacs? Nah, I used to use it at AT&T a long time back but got
fed up of never having it installed as standard on each of the various
development machines I had to use. In the end I was forced to get to grips
with vi simply because it was on every development box, and after that I've
never really seen the point in trying to re-learn all the emacs stuff.
As for LaTeX, that was another thing I never got to grips with. I looked
at it once about 10ish years ago and took a sharp step back when it
seemed to be yet another bunch of *roff-style formatting macros. Again at
AT&T we had to do all our docs on a VT220 using "memorandum macros" which
I found hard to get used to after my spell at Xerox using the Star. Never
really liked seeing all that clutter in my documents, and couldn't be
bothered to run it all through a formatter to see what an approximation
of the end result would look like on a VT220. I know I'm just asking to
be flamed here, but I never saw the point of the whole TeX thing :-)
