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. -- Peter da Silva. `-_-' <peter@sugar.hackercorp.com>.

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. >I don't know how much cheaper this chip is, but it should be worthwhile to >have a look at it. >-- >Peter da Silva. `-_-' ><peter@sugar.hackercorp.com>. -- =----------------Logan-Shaw---(lshaw@ccwf.cc.utexas.edu)----------------= "Trust in the Lord with all thine heart, and lean not on thine own understanding.
