One of the lesser known features of the PCjr was the manufacturing test
mode. I think output was via the ports on the back. (Not the famous
'L' port though, which appears to have no use.) The manufacturing test
mode required a lot less of the machine to be functional than the user
level diagnostics or the advanced diagnostics.
Even for machines that run diagnostics from disk, assuming that the
memory or CPU is ok is a big leap. To do diagnostics correctly you
really need an external processor or an onboard service processor like
midrange machines do, and the appropriate debug ports on the parts you
are going to test.

There are programs to load cassete based programs from the PC soundcard to
the cassette port of a MSX like your CX5M.
Look for
http://www.faq.msxnet.org/suffix.html#CAShttp://home.kabelfoon.nl/~vincentd/
and www.funet.fi/pub/msx for msx cassette files
External floppy drives for MSX are rare. But an external IDE interface is
easy to construct, lookt at the Beer interface on my webpage and generic
CX5M hardware information.

Hi folks,
Anyone here with the hobbyist VMS CDs able to stick the C compiler up on
some webspace for me to download please? I'm on the program myself but
didn't get the CDs because I've got 2001-era layered products CDs that
would normally do fine, but as I've discovered in setting up an Alpha
3000-300LX as a webserver said CDs are 250 miles away and I don't fancy
talking my missus through setting up my MicroVAX 3100-90 and sticking it
on the network (I know, I know, why isn't it already online :o))
I've googled my arse off for an up-to-date version of GNU C that will work
with VMS 7.3-2 and have downloaded v2.7.1 in various flavours, v2.8.0 and
v4.0.1 but the only VMS specific stuff is 2.7.1 and it's not behaving
correctly when I'm trying to compile apps. I could hack the 2.7.1 .CLD
file so it works with later versions but it's nearly midnight in the UK
and I'm tired :)
Anyone?
An e-beer or iBeer is available.

in the 8/32. <http://search.ebay.com/_W0QQsassZrigdonjQQhtZ-1>

Hi Guys,
I've updated the archive with several new images that have been recently
submitted:
Altos 586 developer disks (also has MPM & some other goodies)
Kaypro 3*83 and Kaypro 10
MicroMint SB-180
Grid Compass 1101 (Original Grid)
I've also posted a minor update to ImageDisk (1.06) - no major fixes or functionality change - just cosmecics and minor enhancementws.
Regards,
Dave

Ok, Billerica MA. No shipping possible. Enough to fill a small car and
very heavy. I do not wish to be a shipping broker.

If you know what they are then the size is obvious. I believe they
are deskside to desktop and heavy. I have no data and the current
holder is planning a dump run with them. I already posted where
they are.

Someone wants to film a short (~10 minutes) section of film for a non-profit
movie in the central florida area. They are looking for someone who has 70's
vintage PDP machines with mag tapes & such. Semi-operating condition
preferred. I'm under the impression they'd film where the gear is, so it
wouldn't have to be moved. If anyone can help please email me off-list.

I am doing prop research for an upcoming student short film
which aims to recreate a minicomputer laboratory setting from 1970
and include some close-up shots on various minicomputer gear of the
era, such as the large reel tape based memory storage units and
monochrome consoles.
I happened upon the PDP-11 in course of my research and I
thought I'd just go ahead and ask if there is
anywhere in the state of Florida where we could accomplish this goal
of using authentic 1970's minicomputer hardware in the film.
The runtime will only be 5-10 minutes and the crew and set
should be relatively compact.
I'd appreciate any information or pointers you can help us with.
Thank you!
