AST RESEARCH, INC. TECHNICAL BULLETIN TB-0322 9-25-87 RAMPAGE/2 AND AST CLOCK AST clock circuits that use 32 contiguous I/O locations (200- 2DF) interfere with the RAMpage/2 smartswitch program version 1.0. When installing a RAMpage/2 in the same system with a board product using the above I/O addressing, the smartswitch program will inform the user that there is no smartswitch board in the system. If the clock circuit is disabled the smartswitch installation will operate normally. Some AST products that will display this condition are: MegaPlus II, ComboPlus and I/O Plus II.
