Orchid RamQuest II


Card-ID FEFE (ADF and Initialization file -- both are required!)

Orchid RamQuest II

The Ux component IDs are completely made up. There is no IC on this board that is labeled or identified. I found this in a PS/2 Model 50Z. This adapter seems to do nothing more than emulate the IBM 2 megabyte 16-bit adapter.

Does anyone have the original Orchid option disk or ADF? Tell me!

U1 - L1A3479 (same as the RamQuest 16/32 - does this mean the RamQuest II could do more with an Orchid ADF?)
U2 - Dallas DS1000-125 (Five tap silicon delay line...)
U3 - Lattice 20L8 PAL
RP1 - Resistor Network

The RAM chips on mine are all Fujitsu MB81256-12. (Yes, this is both the ZIPs in row A and the DIPs in rows B and C...)

Why is it possible to disable bank A? (My guess is that you could bypass failed memory this way.)

Orchid was bought out by Micronics. (Micronics made at least one planar/motherboard for IBM to use in a PC Server.) Micronics was bought out by Diamond Multimedia. Diamond did not return my request for information on this adapter. Of course, Diamond has been through a number of different organizations and companies as well.

Globe, Incorporated of New Jersey made the savage purple tabs. They are P/N A1012 and A1006. I thought that Globe had gone out of business (or maybe just didn't have a web site?) but I was wrong!

Any information on this adapter would be very much appreciated! Tell me if you know more!
