DATAMAN S4 MANUAL
EMULATE KEY 47
S4 is impedance-matched to normal drive
conditions, e.g. direct connections to
output buffers. Emulation may not work if
driven with high-impedance lines - via
series resistors, for example.
Emulating 2716 EPROMs
Due to a quirk in S4's hardware, 2716
EPROMs must be emulated at address 00800,
rather than 00000. This means that when
loading a 2716 into S4's RAM, which is
intended to be emulated, it must be loaded into
addresses 00800-00FFF. This is achieved by
pressing the key when in the LOAD routine:
When code is downloaded into S4, it must be
moved to address 00800 prior to emulation.
