*Sorry about the off-topic multiple-posting, but I'm hoping you guys can help me out here; off list, of course! I hate to have hardware sit unused... I have here a pair of EV4 21064 200MHz CPUs, p/n 21-35023-21. One was apparently an upgrade... I was wondering if there is a dual-processor motherboard I could use these on (and where to find one), or what other machines I could use them in... In my DEC3000 System Programmer's Reference, it says the DEC 3000/500X uses the 200MHz 21064. I assume this is the same (as I have above). If so, I could bump my 3000/400 from 133 MHz to 200MHz, right?
