I am looking for a computer board or board set to do a stand-alone,
dedicated job without much user interaction. Any hints on manufacturers that
might make hardware that fits the following criterion would be appreciated.
M68000 based - I have the software and hardware development
tools already and need this level of processing
power (64kw data blocks). 8 or 10 Mhz is fine.
128 kw memory - More than 512k is overkill.
ROM operating system - 32 to 64 kw. Motorola or homegrown or I'll
make my own. Mostly my application with a minimum of
development and debug support routines. No disks.
A serial port - For debugging and intermittant monitoring.
A buss or external I/O - I need to do some A to D for data input
and parallel nibbles out. Can be a commercial buss
or just dedicated ports.
Some interrupt capability but no DMA, multi-user, or multi-tasking.
Nice but not required:
EPROM burning
Second serial port for downloading.
There are a lot of multibus boards out there but most run UNIX or
some other non-real time O/S (no flames, please) and are complete overkill
for my task and budget. I am in the data acquisition hardware design world
and do not mind adapting around something but would like to avoid having
to design the whole computer too. I have 10 68000's collecting data in
another project already so I know what I am up against but they are really
special purpose and not readily applicable to this problem.
I am learning about EMS in Irvine, Ca. Anybody tried their hardware?
Any others out there?.
