I got an old 386 PC :-)
CH-3865-16D VER1.1 (or CH-386S-16D VER1.1)
There are 4 empty sockets and 6 jumpers for SIMMS.
1) Before I inserting the SIMMS: only 384K extended
2) After inserting 2 SIMMS: only 384K.
3) After inserting 4 SIMMS: at first still 384K. I reseted the jumpers in all compinations and got max 1408K extended memory and I remember I also got some extended memory between 384 and 1408K. I should be able to get 4Mb extended memory from the SIMMS, see below.
About the SIMMS:
They have got 9 chips and 30 legs each and they are tested in a 486 PC that have got 4MB total.
KMM591000AT-8 89 40
KM41C1000 AJ-8 (or AT-8)
When turn on the 386PC:
TSENG LABS VGA BIOS MODEL:8925 CLK4B 09/14/90
512KB display memory
Phoenix 80386ROM BIOS PLUS Version 1.1003

640K Base Memory, 01408K extended (384K, before adding the SIMMS)
My question looks not so easy as the points...I will increase the points to 150 if you help me to get all 4Mb extended memory :-)
