Is there X86 and PPC on one mainboard

[asian1]

Hello
There are several Multi CPU machine:
1. PC motherboards with i860 RISC co-processor
for SCSI or Network.
2. Old Olivetti PC with both X86 and Motorola
88K CPU.
3. Multi CPU system from ZIATECH (now Intel).
4. Archistrat PANDA machine with compass bus.
5. The secret Motorola PowerPC 615 (just rumor?)
6. IBM PS/2 950 prototype board for OS/2 PowerPC
(not on the market).
8 years ago, TAOS (the pre-cursor of AmigaDE)
run on top of Quad PowerPC 601 CPU card inside
a DELL Pentium / 80 MHz PC.

Commodore 128 had a Z80 too, you didn´t forget that did you?

The PowerPC 615 was an IBM project, and hardly a secret.  Nor was it what most people figure.

IBM was designing a PowerPC that would have a PC's FSB, so as to use cheaper northbridges.  To allow the PC bios to work, a small x86-compatable core was also included, but you'd have gotten maybe 486DX2 performance out of it.

If we're counting these, we may as well count everything with a GPU or embedded controller.  The I2O initiative made sense from a technical standpoint, but apparently got mired in bureaucracy, and became a dumping ground for the i860 chips when Intel failed to get them into the workstation market.  (Something about focusing the initial compiler efforts on ADA!?)

Not a bad little chip, for 1989.

Edit: Okay, I might be more than a little off here... http://www.wikipedia.org/wiki/Intel_i860 -- i860 and i960 aren't really related; http://www.chipcenter.com/eexpert/dgilbert/dgilbert027.html -- the i960 is the one more associated with I2O?  ...Or did both end up dumped at that market, anyway?  Here's a recentish Intel card on eBay using the i960, can't remember enough part numbers to find more 'vintage' boards.
