This seems like a good place to ask this question - I'd like an Apple Lisa 1 "twiggy" system for my collection, and can trade a working IBM 5100 Portable PC. We'd probably have to meet in person to make the transaction. I'm in So CA.
This is a query which came into TNMOC, but I'm wondering if there are
people here who can assist.

Subject: Comal 80 in Great Britain
Hey there, my name is Mikkel, I am working on a book about a series of
danish micro computers where the history of the programming language
"Comal" will be a part of, and i just discovered that there was a UK
Comal User groups and also a periodical called "Comal Bulletin", ive
searched the internet i cannot find anything. But i hope that you might
know some historians or hobbyist? or even online databases? you can
refer me to?
I would like to know all there is to know about Comal in UK? And as a
sidenote, if somebody knows something about danish computers in uk from
the 70s and 80s i would of course like to hear about that to.
Hope you can help me, more info about my book is here :

I found a bunch of original HP 150 software on 3.5" floppies ...
any HP 150 collectors here? Free, pickup, Cupertino.
Includes the following. About 1/2 are original disks.
The most unusual are probably the compilers from Prospero, and the
IMAGE-like database (Mirage?) from Datasoft International (the developer
was likely Michel Kohon, from France, and a member of the HP 3000

There was a third-party floppy drive for the IBM 5100 :-)
Or at least there as something that was sold in this way. Here is its
Note that it "plugs directly into the Serial I/O Adapter of the IBM 5100
with no hardware or software changes". So it's a serial-port connected
floppy drive that talks to the 5100 in a format that it likes.
(What is an IMF?)

Reviving a year old thread, did anyone get around to dumping the
VAXstation 100 firmware?
I don't see it where I looked here:

Someone on Fesse Bouc just found a sealed box of SS/SD 8" floppies in
Most FB types are too young to know 8" disks existed, of course.
Someone suggested punching a notch in them and using both sides.
Was that even possible on 8" disks?
(TBH single-sided actually-floppy floppies are before my time and I
never used 'em. When they were on low-end American 8-bit home
computers, this impecunious young Brit couldn't afford floppy drives
at all. By the time I could, 5.25" DS/DD was the cheapest drive and

Continuing my exploration of my old stuff pile I'm starting to work on
my Sun 386i systems. Old, no doubt but still there.
First step would be finding a monitor for them. The video cards I have
are the monochrome one, the CGI3 and a CGI5 board. For the color
monitors the cable I have goes to the RGBSync and of course to the
Question: Is there an adapter that can turn the Sun's output to HDMI or
VGA for a more modern monitor?
Im working on an update to Wikipedia on floppy disk drive controllers
there is a nice section on WD but nothing on Intel/NEC
Anyone know the history of how the NEC µPD765 and the Intel 8272 became
AFAICT it was IBM's August 1981 adoption of the NEC µPD765 in the PC that
drove the industry to standardize on the device.
The earliest dates I can find for the two devices are:
8272 listed in Intel catalog (not in 1979 catalog)
µPD765 listed in NEC catalog
µPD765 Data Sheet
As described in the 1978 data sheet the NEC device was 8-inch FD compatible
and of course the PC used 5¼-inch drives but I suspect the differences could
be worked around
It may well be that they were compatible in previous versions (µPD372 and
Any recollections and links would be appreciated
