<$IEmulation of PROMS>Emulates the

is connected to the microprocessor then writing
into USER RAM through
the <$IEMULead>EMULead is possible. The

and returns control to the

S4 emulates ROM and RAM, and may be used to
modify or develop code.
The emulation-lead should be plugged into the
target system ROM or
RAM socket before issuing the emulate command.
Pin-out configuration
of EPROMS is automatic, Chip Enable and Output
Enable signals are
implemented correctly, for JEDEC 27 series
EPROMS. This technique
is an enhancement of ROM-emulation - we call it
Memory-Emulation.
EMULate from address zero.
The EMULead causes S4's RAM to behave like
the PROM itself. The target
system sees the zero address in the emulated
PROM at the zero address
