IBM 5162 - Supersoft/Landmark Diagnostic ROM's
Version 1.2.0
This is the AT version of the diagnostic, intended for the IBM 5170 (IBM AT) and clones. The IBM 5162 is functionally equivalent to the IBM 5170.
Note that the diagnostic's references to chip designators (e.g. U103) refer to to chip designators on the IBM 5170 motherboard, not the 5162 motherboard.
On an IBM 5162 motherboard, sockets U34 and U35 are where the two Supersoft/Landmark ROM's needs to be placed.
The 5162 motherboard requires EPROM's of type 27256 or 27C256 (or equivalent), of an access time of 170 ns, or faster.
Now knowing the above, use the web page at here, noting:
- the ROM for U27 goes into the 5162's U34 socket
- the ROM for U47 goes into the 5162's U35 socket
