- AST RESEARCH TECHNICAL BULLETIN TB-0191 6-24-86
-
-
- RAMPAGE AT/8 MHz
-
-
- It has been determined that the original version of the AST
- Rampage AT board will not operate consistently in the IBM Model
- 339 AT (8 Mhz clock speed). This condition has been verified by
- AST Research.
-
- What may happen with this board installed in the Model 339 AT is
- that either the REMM.SYS program will not recognize any Rampage
- AT memory, or "Parity errors" will be generated when attempting
- to address the memory.
-
- These boards can be identified by their revision level. This
- number can be found on the back (solder side) of the board,
- etched along the edge of the board that is opposite the mounting
- bracket. Any board with one of the following numbers should be
- considered suspect:
-
- 202079 - 301 -A, -B, or -C
- 202079 - 302 -A
-
- These customers should contact AST Research to have their
- Rampage AT exchanged for a later revision.
-
- If the revision level is the following (or above) the board will
- operate in the Model 339 AT:
-
- 202079 - 302 -C
-
