- Overdrive Socket?
-
- I don't think so. IBM does not have a history of using the
- overdrive socket. I think instead you get a new daughterboard with teh
- 486/66 on it that you place in your 77.
-
- Local-bus SCSI?
-
- I thought local bus was limited to ISA and didn't exist with
- MCA machines? I don't know why they would have local bus for MCA especially
- considering if you have busmastering cards you can effectively transfer
- data as fast as local bus.
-
-
- SCSI-2?
- I don't know if the scsi controller in the 77 is a scsi-2 controller
- but it is a new 32-bit scsi controller made by IBM and it is cached.
- I think the cache is something like 512k.
