Anybody seen this one?
I'm running into a problem with a set of disks (original Visual 1050 system
disks) where when teledisk gets to cyl 80 it pops up an error box "Drive A: is
not ready. Please correct and press any key to continue". Needless to say,
nothing I've tried gets past this error. Teledisk usually seems fairly
tolerant of most errors and will keep chugging, but not so in this case. I
tried a few versions, the latest I have is 2.16, all behave the same.
Any ideas?

c20 = An unexpected halt occurred, and the system is configured to enter
the kernel debug program instead of entering a system dump.

OFF TOPIC - but ya never know.
I have for sale the physical assets of a transformer and coil winding
company: 3 Boesch toroidial winders, four multi-bobbin straight winders
with tensoiners, thousands of pounds of wire from #46 to #10, Litz wires,
thousands of pounds of laminations and core materials, tens of thousands
of toroid cores all segregated and in steel bins, plus headers, bobbins,
terminals, tape, vacuum pots, manuals, etc.
Contact me off list: stuff is going just for my investment in it, and
it's located in Northern California - I moved the whole load in one 24'
UHaul truck, about 9000 lbs all up.
Cheers

Nearly half a year ago I put out version 0.5 of my Wang 2200 emulator.
Life got busy, and it has taken a lot longer than I expected to get
version 1.0 ready. With this release, the source code is also available.
If you want to take a look, here the link to the emulator, including
release notes:
http://www.thebattles.net/wang/emu.html
The "front door" to the Wang 2200 site is here:
http://www.thebattles.net/wang/wang.html
The emulator is written for a Win32 environment, although it might just
run under Wine on Linux, or one of the Mac PC emulators. I don't use
anything too exotic in the Win32 API. The zip file contains a couple
dozen programs to try out.
Background:
What is the 2200? It was first announced by Wang Computers in 1971 or
so, and was a dedicated BASIC-only machine. It is a TTL-based CPU that
had ROM'd microcode to implement the BASIC interpreter. The BASIC is
interesting in that it is ideosyncratic: weak in some areas (statically
sized string variables), very strong in others (MAT SORT anyone?).
Hi,
I'm trying to track down a copy of the NEC V20 Hardware Manual. I've
managed to find a PDF version of the Software (programming) Manual, but the
Hardware Manual (which, typically, is filled with the info I need to get
this thing running) is a pain in the neck to find, especially now the V20 is
classified as obsolete by NEC.
I'm also after a copy of the schematics for the original IBM PC-AT and
PC-XT. Anyone got a set they can scan or photocopy for me?
Thanks.

I just obtained an RS/6000 C20 and am having problems
getting access to the serial console. I know the null
cable and terminal I'm using works, but I can't get anything to display.
It runs through its post and ends up with c20 on the front
panel display, I don't know if its booted up correctly
and displaying its name or stalled at an error.
Help!
Gentlemen:
I live in Baton Rouge and had reason to visit Surplus Solutions today.
Surplus Solutions is a seller on ebay for used comp equipment and has VERY low
prices (especially when you don't have to pay freight). I was talking to the
owner regarding mainframe systems and asked if they had any. He replied "they
don't move well on ebay, but I do have some old main frame stuff, including
several pallets of VAX" What doesn't sell on ebay gets scrapped. He also
said he would try relisting some of the stuff
He does not have an inventory list, all they do is ebay, however he said
they do accept inquiries via phone or email, do sell direct and would welcome
my posting this, along with any inquiries regarding the stuff.
They are "SurplusSolutions" on ebay, do a seller search and you will hit
on dozens of pages of listings.
I AM IN NO WAY AFFILIATED WITH THIS COMPANY, I do however share in the
belief that a lot of this old stuff should not meet the scrappers.
I may be contacted off list if needed, to possibly help with pickups or
storage or possibly get a picture or two of something (if I can convince them
to allow it).
Sorry, I don't have their phone or email handy, you'll need to get it off
ebay

I will try to make a weekend project out of typing in the ROM listing from
the source in the manual and then post it somewhere.

Something like that... the original CMI certainly has a pair of 6800s... I'd
need to RTFM to remind myself how they interacted.
I have one - an original Mark I CMI, probably my favourite 'small' system,
see:
http://www.corestore.org/fl2.htm (page of detail thumbnails)
and
http://www.corestore.org/fairlight.jpg (nice LARGE pic of whole system)
It's in pretty-near perfect shape, and works very nicely! The software they
managed to implement on a pair of 6800s is one of the most truly awesome
hacks I've ever seen. I'll bring it to the next VCF-East... I'm in process
of doing a proper web page about it.

I have a 1990 or so Sharp ZQ-5200 organizer up for grabs.
It has 64KB memory. Includes manual and original box.
No batteries. It was working last time it had batteries.
Cost is shipping. If you are interested, email me.
