I want to thank everyone for their replies to my query. To
summarize:
Several people suggest that I dig up some used SUN 3/50s or 2/50s
motherboards. Not a bad choice but I'd prefer something without
the extra hardware (scsi, mmu paging support, etc). This still
might be the way I go.
One person suggest that I check out Motorola board products.
That's what I am currently doing now.
And one person had a good deal on a Stride system. (I might take
them up on it for my personal play machine -- grin) I'd rather
not do one of a kind hardware for this project, even tho that's
the way it started out...
I have also checked into the Mizar MZ (not MX I has previously
mistyped) series. These appear to be good solid systems. And
they are another good choice. For my own project I'd have to mix
one of the MZ 8120 boards (68020 at 16Mhz, 1 Meg, 2 serial ports,
clock chip and VME controller) with one of their EMX 7550 boards
(a smart LANCE based ethernet interface with a 1/4 meg of local
buffer onboard).
I also checked with FORCE computers. They had a very good system
but it was overkill (both price and features) for what I am doing.
It was a 68030 with 4Meg, 4 serial ports, SCSI and a LANCE. Very
nice system, just a bit too much for my shoestring budget -- grin.
So... Thanx again for all who replied. In case you are wondering I'm
migrating our (UNO's) network monitoring system from PDP-11/23(73)
based systems to something that will be faster and a bit more reliable
under harsh conditions. We've had the traces eaten off of the boards
in some of our network equipment lockers!! We definitely have some
environmental problems. At least with new/smaller hardware I can
protect it a bit better (besides the fact that it will be MUCH
faster).

Look at the Gespac line of products. They have a basic 68000 board
for $400 and a full line of peripherals and other CPUs ('020, '030'
'286, '386, 8088, T800, 6809, 8085) that share the G64 bus. They also
offer software, featuring OS-9 but covering a broad range. Their
address is
50 west Hoover Ave.
Mesa AZ 85210
(800)443-7722
I have no connection with this company but have been looking at their
line myself.

You can get Amiga 1000s used (only lacking keyboards) for something like $150, or a brand-new Amiga 500 for less than $500. Since it's a fairly mature machine, the tech docs and development tools are good, and since it's not obsolete, you can actually get them. Plus you can always hop on to comp.sys.amiga.tech and get answers... Of course, I'm biased because I own and develope software for the Amiga (and happen to love it!), but what the heck...:-) -- Dan Babcock
