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
