Hi Ethan
?? The LINUX port is for a very practical purposes. That being, the ability to show a high
level of competence in LINUX kernel and LINUX device driver development.
Hopefully this will make it easier for me to get contract doing that type of work. It is
an area of software development I would like get back to. I have too many years in the
financial industry and would like to get back to my roots for the rest of my career even
if it means taking a significant pay cut. Actually what I would love getting into is one
of those interesting DOD/DOE project.
Finally it will be a fun project for me putting the last of my unused IEEE-696 boards to
use. I have not intension of becoming a pack rat like so many of my fellow collector of
this old stuff.?
If I did not have that rule my apartment would become cluttered with lots of stuff I never
get around to using. You can get a feel to what my work space looks like now by viewing

The ALTAIR 8800b in the page is probably the only thing I may not get to by years end.
Well, that is all there is to it.

Now that you mentioned I think I may revisit making a
16MB board for the
S100 bus for my upcoming LINUX port. The amount of headache I am
having getting
what I want is becoming a bit too much.
I'm interested in hearing more about your Linux port. I don't have
any S-100 stuff (I gave away everything I got from Software Results
years ago), but I do still have a pile of our 68000 and 68010-based
products, the schematics, PAL equations, application and firmware
source, etc. I have enough boards that if there was something
interesting to do with them (besides being intelligent Qbus, Unibus
and VAXBI synchronous serial controllers), I could blow some new
firmware and turn them into hobby boards.
As it is, all of our products were designed to have a "payload"
application dumped onto them when starting a new serial link, so the
ROM code is pretty much only smart enough for simple diagnostics and
receiving a new "front end program". We didn't have an OS, just
a
monolithic app for each board and serial protocol (HASP, 3780, and SNA
PU Type 2). The earliest boards (c. 1982) really just run a state
machine written in assembler to pump serial streams out the serial
chip and blocked data over the Unibus DMA interface, and occasionally
something out the printer port. Later stuff got much more involved
and had much more memory, more ports, etc.
With all that time spent in that realm, I'm always interested in
hearing what folks are doing with the 68K.
