Hi All,
I'm trying to piece together an Altair 680 and am looking for a motherboard and display board, either for sale or trade. Either new or replica would be fine.
Thanks,

Hi!
I'd like to install on an old i386SX-16 mainboard. It comes along with
8MB RAM and 387-25 co-processor.
My problem is that none of the 42 predefined HDD types fits my HDD,
unfortunately not even the heads and sectors settings. (Missing some
of the HDD's space due to a too small cylinders value wouldn't be a
problem.)
So I've got this mainboard. I cannot find a model description
somewhere, only "REV 2B" and "COPYRIGHT 1989". Quality assurance sticker
displays "HOWTEH Q.A", another sticker has "S/N: H 3204328" on it.
During boot-up, "386SX/82335 Modular BIOS Version 3.04 (P24)" and
"Copyright(c) 1984-88 Award Software Inc." are displayed, Ctrl+Alt+ESC
gives the BIOS settings screen. (A photo can be found at
http://lug-owl.de/~jbglaw/i386SX.jpeg .)
My problem is that HDD settings 1 to 42 don't fit my HDD in any way.
43 to 47 contain all-zeroes values, so I guess they're all used for
user-defined type. However, I cannot figure out any way to enter my
correct C/H/S values. The displayed help is correct, but not exactly
helpful to enter those numbers :) Maybe anybody recognizes this BIOS
and can give me a hint?
Thanks, JBG

Not to burst any balloons, but LC IIs are not particularly interesting
Macs nor particularly rare. Some people like them for their form factor,
but I wouldn't expect it to fetch more than a few dollars unless it has
a lot of options installed.

In this case, there's plastic in the way on the component side.
Adding heat did the trick though. I went out into the garage and
grabbed my propane torch (1 quart bottle size). I used it to heat the
tip of the desoldering iron. That made the process go much faster
since the solder melted instantly. Then when I tried to pull out the
part, I heated the solder side of the board. That let the part fall
out. Works great when you don't care about ruining the circuit board.
:-)
The 16-bit part of the isa connector was attached to the 8-bit part.
I used a bandsaw to cut through the connectors and free the half I
needed.
Now it's time to solder the isa connectors to the 2000 motherboard.
It's the scary part for me. :-)

Now you just need to do the 25 MHz => 33 MHz modification (couple of
resistors) <http://homepage.mac.com/schrier/q605.html> or, if you're
really ambitious and can find a MC88916DW80 do the 25 MHz => 40 MHz
modification.

The latter may also require 80ns VRAM.

All,
I have a VAX 6000 model 410 available for free.
It must go before the end of January but if interested,
let me know before then end of the week.
Machine has been switched of about 3 years ago and it's
only the CPU cabinet, no additional cab's.
If more details can be recovered, I'll post them.
Regards,
Ed

Thanks to Dave for his generosity in making these tools available again.

For those following GopherVR's evolution, a "virtual reality" interface to
Gopherspace, version 0.4 is out. This fixes a lot of problems and makes it
much more controllable. You can get the source, plus pre-built Universal
binaries for Mac OS X 10.4 through 10.6, and see screenshots at

Hi,
Does anyone have a complete Package of AT&T SYS V
UNIX for a the 386. I Have a AT&T 386/20 WGS computer
that came with the software but when I looked closer, it does
not have the boot disk (set up) or the license if it needs
one. It has all of the rest of the floppies. I also have a few
QIC tapes but with the same problem, no boot floppy.
ESDI drive finally died so I need to start over.
