Identifying Your Model

  An important part of properly assembling your system is to know WHAT it is. There were 12 different complexes used in the 90 and 95 models. Each complex has certain limits and capabilities.

WARNING! Complexes can be swapped between model 90 and model 95 machines. If you can, look at the complex itself to positively ID it. Or if you know the differences between the four Types, you can rely on the processor chip alone.

   There is some confusion that newcomers have. IBM identified systems by Type (8590, 8595...) and Model (OG9, OKF...) so a Model 90 could be a OG9 or an OKF or DLA... Or it could be a 9590...

Where to find the Type-Model
Model Operator Panel
Model 8557 / 9577
  Desktop. The 9577 series has two major versions, the Lacuna planar 9577 i/s and the older Bermuda planar 9577
  The older 8557 were 386 class machines.


Model 8556 / 9576
  Desktop. The 9576 series has two major versions, the Lacuna planar 9576 i/s and the older Bermuda planar 9576
  The older 8556 were 386 class machines.
 Image when I get to it. The Type-Model sticker is directly below the power switch.
Model 8590 / 9590 
  Desktop model. It has NO LED panel.
Model -x?x, -xGx, -xJx, -xKx, -xHx, -xLx
   The -x?x model is a 386DX-20. No known suffix for it.

Planar is HERE

Model 9585  The 85 has a blank panel. In addition, the cpu is on the planar (no complex). The 85 has the same case as the 95.
Model -xXx

Model -xKx or -xNx

Model 8595 / 9595
Model -xGx, -xJx, -xKx, -xHx, -xLx, -xMx
  The power button may not have a shutter over it on the early models.
 There are two upgrade complexes, the DX2-66 and the DX50  They do not have a model associated with them.
  The planar is HERE
Model 9595A
 Model -xNx, -xPx, -xQx, and -xYx
  The "A" refers to the improved planar on these models.
