through the 40-pin ribbon cable from the optoisolation board or
low-voltage power stage.
The control board is designed to run in two configurations. It can be
connected to an M68EM08MR32 emulator via an M68CBL08A
impedance matched ribbon cable, or it can operate using the daughter
board. The M68EM08MR32 emulator board may be used in either an
MMDS05/08 or MMEVS05/08 emulation system.
Figure 4-4 shows a block diagram of the board's circuitry.
