says... I wrote this up yesterday, but for some reason it apparently got lost in the aether...

Showed that we didn't need IBM for what ? We didn't need IBM to design and produce unreliable ill-thought, poor performing, hard to install I-O busses ? Not entirely true in the case of VESA because it had IBM's PC-AT bus embedded in it anyway.

Come to think of it, it wasn't until PCI-X came along that PCI acquired the RAS essentials for high-end systems that MCA had all along. IBM, HP & Compaq were the big names behind PCI-X, take note : They all sold big-iron. Of those just one continues to make big money selling big iron, and it sure as hell ain't HP.

I'm not sure there ever was any real compebreastion. The timing and the feature sets barely meshed, same goes with EISA. For example MCA had parity on the data and address lines. AFAICT EISA and VLB didn't do parity full-stop, so much for basic RAS support. :

I'm going to dig out Mueller's book on PC maintenance... If it were far better, then PCI would never have survived...

A few dates for you : 1987 - MCA (AFAICT MCA boxes were shipped in 2002 !) 1988 - EISA (RIP ~1995) 1992 - VESA Local Bus (RIP ~1995) 1993 - PCI 1999 - PCI-X 2002 - PCI-Express

Having taken a look at MCA, it actually looks pretty simple to interface to, easier than PCI at any rate. ;)

Cheers, Rupert
