Got this without BIOS but I used the one from #51 with the same Chipset (THANKS CMB75!) and it boots.

To get rid of error messages I had to set in addition to the config shown on the photo (maybe I take new one later)
JP1: 2-3 closed (to use W27C512 ROMs - otherwise checksum error)

To get rid of RAM config errors:
JP13: 1-2 closed
JP4: closed

Hello Tildo,

about your PCD-2L/-2M System I'd like to ask if you got and could copy (hw-) documentation for me?
My System Manual (A22451-A4430-X21-1-7618) is not really helping with connections as i have not the housing with those cables (power,speaker etc.) .
On my nearly identical board (only part of PCD-2 that I own) is written on upper edge:
Board : W26361-D458-Z4-06-05 + CPUAZ-S26361-D458-V102(that white stamp)
Chipset : Intel/Zymos POACH 1 82C230-12, Intel/Zymos POACH 8 82C331, VLSI VL16C452-QC
BIOS : Tandon V5.21 on pair of 27C256 type ROM chips.
A photo should be attached, but i got an error . Saying : "The submitted form was invalid. Try submitting again" and then ...never ending upload. Although I compressed it just under 1MB. So I draw back, no photo.
About the docs, reply if you want to send. Then we connect by sending my a E-Mail over PM?

So far, hoping to hear from you
Markus

I hope to get the format of the post right.

It seems that V2.01 dumped by @Schule04 is not the last version after all.

unknown vendor/model. closest match i found is "286LS" by "JPN Corporation." https://stason.org/TULARC/pc/motherboards/J/J … -286-286LS.html

strong resemblance to #6 and #42 but has SIMM sockets instead of SIPP, and AMIBIOS instead of Quadtel or Phoenix.

board has date sticker from August 1992. (not visible in photo; it's attached to a slot)

my Suntac-based board, similar to #61 and probably by the same generic manufacturer.

jdupes says my BIOS does not match anything in predator99's archive, so i am posting it here. there is a version "3.03HL" already posted but my version is 64k instead of 32k.

EDIT: the BIOS does indeed match v3.03HL in predator99's archive; my version is just an overdump and i didn't notice. carry on!
