Model 90 with Type 0
rf90386a.exe Refdisk for Model 90 and Type 0 386DX Complex @FDDE.ADF - IBM Enh. 80386 Memory Exp. Adapter w/ROM CFDDE.ADF - Init file for @FDDE.ADF Weitek 3167 on Type 0 Complex (!!!) ![]() A good image showing the clean configuration. Planar XGA, 160MB DBA-ESDI, 4x 2MB 85nS on one riser, 8MB (4x 2MB 80nS) on 2-14 80386 Memory Adapter w/ROM. About the only thing missing is support for 8x 2MB 85nS on the risers. That would give us 16MB with no need for a memory expansion adapter taking one slot... ![]() This side view shows the DBA-ESDI edge connector seated into the planar socket. I do not know if the old style risers (with electrolytic caps between SIMMs) is the key to success, or if the new memory risers also work. ![]() Total System Memory reports 16.0MB installed, 15.6MB Usable (includes memory adapter!) Built In Features, Installed Memory reports 8.0MB (planar memory) ![]() Usable System-Board Memory is "Parity"... I didn't know there was a choice... Enhanced 80386 Memory Expansion Adapter w/ROM Installed Memory is 8.0MB ROM Address DE000 - DFFFF.... ![]() And here is the 160MB DBA-ESDI, Integrated Fixed Disk and Controller. Weitek 3167 on Type 0 ![]() Well, this proves the 3167 is socket compatible with the Type 0 complex FPU socket. Something I did not know. 3167 POST ![]() 3167 looks to be supported by the Type 0 complex. Note: The 3167 is a single chip successor to the three-chip 1167 (163, 1164, 1165) X1163 Databus X1164 Multiply / Divide Unit X1165 Arithmetic Unit 3167 Phong Shading Demo ![]() AdapterID DF9F Integrated Fixed Disk and Controller (inegrated into planar ADF) DMA Arbitration Level
