Or if 98% of pins are standard in places, cut few traces and rewire? This is done for adapting generic 30 pins simms for few certain IBM machines. AST machines and queer machines that use 64pin simms! I have bunch of those little 64pin 1MB and rare few 4MB usually comes out of AST 486 bravo series cpu on a card types. 1. The # of chips on both 64pin and 72pin are same therefore 32bit per stick plus 1bit every byte of data for parity = 9 or 18, non parity 8 or 16 chips, except for some early 12 chip parity simms. 2. There's is no TTL chips anywhere on those AST 64pin simms and wasn't any non-standard DRAMs either. AST is bad as Compaq using oddball memory modules in all shapes on many early to mid 90's compaq machines. I think that IIfx 60ns or 53ns speed for dram due to 40 or hacked 50 MHz IIfx's? IBM is not *that* bad like this, 99% of time these machines they produced since the ps/2 series used standard types except 25/30 series (except make it work by this hack noted above) and few early to mid 90's used either standard or ECC in same machines. I'm not including those RS6000 series which is totally different animal to this topic. Cheers, Wizard

It was just a matter of time, what with people shoehorning early PPC mainboards into the case of a Color Classic...well, someone has now done it with the G4 Cube mainboard! Me, I've taken the easier route and just popped a LC-575 mainboard into mine...no case mods needed for that one. Anyway, here's the story on the Color Classic G4... http://www.mac512.com/ccpmg4.htm Jeff -- Collector of Classic Microcomputers and Video Game Systems: Home of the TRS-80 Model 2000 FAQ File http://www.geocities.com/siliconvalley/lakes/6757
