Orchid RamQuest II MC

@FEFE.ADF IBM 2 MB 16-bit Memory Adapter

RamQuest_II_Files.zip ZIP of the option diskette's contents.

This adapter seems to do nothing more than emulate the IBM 16-bit 2 megabyte extended memory adapter. However, I've not yet tried using it with the option disk provided below.

Have you got any documentation or other information about this adapter? Tell us!

RamQuest II MC (RamQuest IIz - variant for Model 50Z?)

Orchid RamQuest II

The Ux component IDs are completely made up.

RP1 Resistor Network
U1 L1A3479
U2 Dallas DS1000-125 Delay line
U3 Lattice 20L8 PAL

U1 L1A3479 (same as the RamQuest 16/32 - does this mean the RamQuest II could do more with an Orchid ADF?)

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...) Memory in bank A is soldered in place.

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

Orchid Technology Today

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. It's likely that anyone working there now has no memory of these older products. Whatever records existed about these products have probably been tossed 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!
