- IBM has stated numerous times it will be delivering a LocalBus/MCA
- dual architecture machine (or two :-)) in the near future. It is not
- yet clear whether that LocalBus design will be VESA or Intel PCI, but
- it will be one of the two.
-
- I wouldn't exactly call MCA dead, by the way. It has a far larger
- market share than EISA (with no sign of change there; perhaps the
- opposite, in fact), and it is part of the third (or second, depending
- on whose figures you believe) best selling workstation line (the IBM
- RS/6000). It is available from third parties, notably NCR and Reply.
-
- While I'm on this subject, LocalBus isn't the only new bus
- architecture vying for a place. PCMCIA is also in the running, and
- you'll see machines from IBM (both desktop and notebook) with PCMCIA
- slots. They each have a place.
-
- I should also mention that several vendors (IBM and Compaq, notably)
- have had "LocalBus" video adapters for some time. By placing the
- video on the motherboard these manufacturers did not have to worry
- about AT bus limitations. (True LocalBus, of course, offers up to
- three slots, which means the video circuitry can be replaced and still
- stay local.)
