Emulator Processor Modules
One thrne-function jumper is located on the 9900 Emulator Processor module. This jumper
allows the 9900 Emulator Processor to operate with the standard version or new, fast version
of Program Memory. In the upper or "Slow" position of the jumper, the 9900 Emu later
Processor module will add a wait state* during every memory access except in operating
mode 2. Placing the jumper in the lower or "Fast" position allows the 9900 Emulator
Processor to run at full speed, adding no wait states except during debug operations. If the
jumper is removed entirely, a wait state is added to every memory access regardless of the
mode of operation. When the 9900 Emulator Processor is used in conjunction with the
Maintenance Front Panel, the jumper must be removed.
*A wait state adds 1 /(clock frequency) ns to each memory access.
