another option...
if you are interested in pc104 and isa, then please have a look at the
epics brick (ebrick). send any questions you might have.

May I also suggest that you have a look at the ColdFire uCDIMM cards
that we are using here at the APS and Till Straumann is using at
SLAC. These are full-capable EPICS IOCs and are well supported by
both RTEMS and uClinux.

64 MHz Motorola ColdFire MCF5282

4 MB of on-board flash (in addition to the 0.5 MB on the MCF5282)

16 MB of DRAM

10/100 BaseT Ethernet

Three serial ports

I2C, CAN, QSPI

A24, D16 bus(with 2 chip-selects)
Here are a couple of references:

Dear Mister du Toit

The bad news is that most of this hardware is custom made... and is

fairly old. This includes just about everything from powersupply

controllers to vacuum controllers to beam monitors ect ect.

The one advantage is that most of this runs in crates on a bus we call

SABUS (once again custom made) in basic form it is a parallel

communication bus with data and address lines and some control signals.

This is also a system that connects several of these crates together.

Then you have a differential system that has an 8-bit data bus and
about

4 control signals.
This bus seems to be something like the ISA bus. I made here at BESSY
somthing similar 13 years ago, a little 8-bit addr, 8bit data + some
control bus and adapted this easily to an ISA bus. So an idea could
be to use PC104 with ISA bus, create a adapter to your bus and than
there is just the work to create an driver for the bus access and
device support to the records. This PC104 boards are shurely more
cheap as a self developed one, and there is not much work on the
software side, I think.
