This adapter implements
IBM's Translation RAM, used by Micro Channel based
PS/2s to remap failed system or adapter board memory
during POST. 100 ns or faster 9 chip 30 pin SIMMs. Will
operate in a 16 or 32 bit slot.
Files include Disk Cache,
RamDisk, Expanded Memory Manager (EMS 4.0), Print
Spooler
Com1-8, 150 to 9,600 bps. Stop bit on/off, parity even
or odd.
Parallel port can be configured as LPT2 or LPT3.
Note: LPT2 is the clone LPT1.

Snippets
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.
