And unless I'm mistaken, Autocad ran on a cga equipped 5150 through version 7 or 9. I think it was 9 I got from the job. And all they had in my dept was the early 5150. Later upgraded it to a hybrid 286.

So why didn't you use a terminal? You can run a video card and a terminal simultaneously, no?
That...might be a good place to look! I may already have every IBeeMer refernce manual known to man (or wimminz). Also got another journal thing on the subject. Where is that thing...
But what I was looking foris more or less a skeleton flowchart description. Maybe if I hum and contemplate Josh's goofy answer, I'll come to the discovery that it's sufficient. NOT.

In my long-running tradition of obscure requests...
Does anyone know if a copy of the Qudos Ltd "MINICHIP" gate array design
tool still exists anywhere?
This was a CAD tool designed for the BBC Micro (with 6502 Second
Processor) which allowed the machine to be used for the design of
Ferranti ULA gate arrays.
There was also a similar tool called "Quickchip" for the Acorn
Archimedes ("A440 only" according to page 22 of this:
http://acorn.chriswhy.co.uk/docs/Acorn/Brochures/Acorn_APP155_HardwareExpan…
)
There's some mention of MINICHIP here:
http://www.chilton-computing.org.uk/inf/literature/newsletters//ecn01-20/p0…http://books.google.co.uk/books?id=GzPpAAAAIAAJ&lpg=PA85&ots=sR_gUYkMii&dq=…
I'm also interested in a copy of any documentation on Ferranti ULAs -
databooks, details on the logic cells (specifically the ULA9C series but
ULA5C may also be useful), design software (or documentation thereof)
and so on. Examples:
Qudos Ltd. - Qudos Logic Array Design Software Manual QED2 (pub. 1986)
Ferranti - Ferranti ULA Design Manual A/F002 (pub. 1981)
Guessing what I'm trying to do is left as an exercise to the reader...
but it involves photos of the Tube ULA layer masks and a copy of
Degate... :P
Thanks,

Got one too :)
But the "box" doesn't work, too well anyway. I just figured I could hit ya up for a rom image if necessary.

Its not going to be rpi specific but it will be at risk for any standard exploit for services it hosts. You could pwn it via apache, dns, mail server, etc but again its mostly app vulnerabilities and no real blame to the product itself.
For protection it shouldn't have any problem running simple iptables (firewall rules), clamav (on demand virus scanner) if desired or I suppose even snort or other ids/ips although thatd certainly take away from the limited resources.
Either way it should have all the charm of the ported OS.
