There is a chip called the 68EC030, which is basically a 68030 with the MMU
cut out (according to Tyler Sperry, editor of Embedded Systems Programming, it
looks like they had a batch of 68030s with broken MMUs and decided to sell
them as embedded controllers. Be that as it may...).

This would make a nice chip to put in a LUCAS-style board. It doesn't have an
MMU, but that's not a major problem in an Amiga. No, you can't play games with
moving the ROMs into protected RAM, but it should hum along just fine as an
accelerator.

I don't know how much cheaper this chip is, but it should be worthwhile to have
a look at it.

Unless you wanna run UNIX...

I suggest the Krueger company for cheap motorola chips.  They advertise in
Amazing Computing.  My roommate bought a 68881 from them and had no problem
with it, though it looked like it probably had been pulled from some
equipment.  Other than as the fact that my roommate is a satisfied costumer,
I have no relation to the Krueger company.

No offense meant Logan but the above was too humorous for me to pass up.

yours truly,
