Ian Pitcher:
   I got an "Orchid RamQuest Extra 16/32" yesterday that I installed in my 9556 yesterday. I grabbed the ADF for it, and it configured just fine. I think this card accepts either 256KB or 1MB (30-pin) SIMMs in its banks. I assumed that it needs at least 100 ns RAM, which I supplied it with and it still doesn't see the extra RAM that I put in. I have 16MB on the planar, which I believe is the most that will be addressable by the 486SLC2, but I figured this adapter would help me get around that. I know this isn't my problem anyway, since it doesn't see RAM on the orchid even with one of the 8MB SIMMs removed from the planar.

From Peter:
   The RamQuest 32/16 to my knowledge is a memory card to be used with a "linear" (unmapped) addressing model - like in a 386DX-class machine - and therefore does not support LIM/EMS. It is not recommended to use this card in a Mod. 90 or 95 - these machines merely support channel memory rather than planar memory. It will probably run - but very slow. These cards are designed for a 386-architecture rather than a 486-environment.

Tim Clarke:
   I had one of these (well... it's still under 'my control' in my brother's machine). The BIOS ROM limits total (planar + card) memory to 16MB-128KB (for Model 50/50Z etc.). Actually, that's what it *should* limit it to, but the v1.1 ROM has a bug which makes the limit 0x3E00 kilobytes, or 16MB-512KB. Anyway, the EMS driver supplied *will* manipulate the hardware to provide <= 8MB of EMS memory without requiring any more than the usual 64KB upper memory area 'window'. Yes, it takes 100 ns or faster full parity 30-pin SIMMs, but has a distinct preference for 9-chip versions, or aversion to some 3-chip versions (timing sensitivity?). Also, I disassembled the supplied EMS driver and it plays with the hardware quite nicely.

Updated RamQuest Extra ROM

Ask about RQXBIO1A.BIN for "V1.1 Adapted ROM" from Tim Clarke.

After much reading, thinking, fiddling with the code and trying to test in an unsuitable system, I think we may have to say the modification is lost and gone forever.

I include a copy of what I think the modified image was. It's an 8KB image due to the EPROM size, but only the first 4KB is actually code etc., the rest is set to hex FFs. During my unsuitable system testing, the Start Address would show up as " --  " because the original ADF only has a limited set of possibilities for Start Address. I've attached a modified ADF with many more possibilities, in case a knowledgeable individual with the right kind of system (50,50Z,60,70,80), adapter and ADF manipulation skills (rename, backup, copy on floppy RefDisk) is willing to test them. But I'd rather they weren't made publicly available, due to lack of testing. There are also test considerations of system RAM installed, split memory block and ROM to RAM copy (70 and 80 and later systems) and other factors, which aren't common knowledge.

Regarding the RamQuest page, there is no support for 4MB 30-pin SIMMs in the code. So, it's 8MB maximum onboard and the table entries for 4MB SIMMs aren't valid, unless that's for one of the other boards. Also, I'm pretty sure it's 24-bit address decode limited. There's also a reference to a JP2 jumper, which my Rev. C RamQuest Extra 16/32 board doesn't have. Maybe this refers to one of the other RamQuest boards listed? (Ed. IIRC, there was a RamQuest XT board).

Please note that I've only ever used it in PS/2 Model 80s (8580-111 and -A16), so any user should retain their original ROM (mine was an 8KB Intel D2764) and burn a new one, just in case it gives problems in 286-based models.

8-Pin Round DIN to 25-Pin Serial Converter Layout (from Peter)

Here's a diagram of the converter cable ("pigtail"):

8-pin DIN                         25-pin Male 
1 DTR =----------------------------------= 20
2 CTS =----------------------------------=  5
3 TXD =----------------------------------=  2
4 RI  =----------------------------------= 22
5 RXD =----------------------------------=  3
6 RTS =----------------------------------=  4
7 DSR =----------------------------------=  6
8 CD  =----------------------------------=  8
9 GND =----------------------------------=  7

Pin 9 is the outer shield ("Collar") of the Mini-DIN plug.
