- I have here the glossy on the Micronics VL-bus motherboard, and a few
- details in its design give me reservations. Namely, the entire memory
- subsystem appears to use oddball SIMMS; the main memory is needs 36-bit
- ones on a 70-pin carrier, whereas I was under the impression that 72-pin
- carriers were prevalent in this size. It's probably not worth wondering
- what engineering decision resulted in a 12-chip SIMM (as depicted in
- their photo) instead of 9 chips. The cache subsystem is available in
- two sizes, 64k and 256k, but again these are mounted to an even longer
- SIMM, which pretty much ties you to whatever speed (and price) parts
- Micronics sees fit to ship. Somebody, please tell me that my concerns
- are unfounded...
-
- I noticed in one of Ken Germann's blurbs that Zeos is also going with
- 36-bit SIMMS...how many pins are they using?
-
- Just for the record, assuming that this really is the VL-bus that Computer
- Shopper reports was unanimously approved at the last VESA meeting and not
- another case of marketing hype, it looks as though they've gone with an
- EISA-type connector with one slot key, about 2/3 the length of the full ISA
- connector and placed right next to it. Looks a lot like what V-COM is
- currently using, but I'm not certain about that. The board also sports a
- 169-pin OverDrive socket, and on-board I/O consisting of 1p2s, a 2.88
- floppy controller, and some sort of new IDE controller sitting on the VL-bus.
- Nobody I talked to had any sort of pricing or availability information yet,
- but then again, I didn't call Micronics directly.
