Intel imm6-76 PROM programmer

Simple programmer for 1602/1702 and 1602A/1702A 256x8 static PMOS
UVEPROMs (1602/1602A have a metal lid preventing erasure but are
otherwise identical to 1702/1702A). Used in the INTELLEC® 4 and
INTELLEC® 8 development systems.

P1 universal edge connector (only used for power)

DO are open-collector TTL outputs with 5.6kΩ pullups.

DATA OUT ENABLE has an onboard 5.6kΩ pullup. Driving it low disables DO
outputs.

DATA IN + TRUE (if jumpered in) has a 5.6kΩ pullup and is XORed with the
DI inputs.  It should be pulled low in systems that use negative logic.
It is not jumpered in when used with INTELLEC 4 or INTELLEC 8 systems.

/DATA OUT + TRUE (if jumpered in) has a 5.6kΩ and is XORed with the PROM
data outputs.  It should be pulled low in systems that use positive
logic.  It is not jumpered in when used with INTELLEC 4 or INTELLEC 8
systems, the line is tied low with an onboard jumper.

/PRGM PROM PWR has a 27kΩ pullup to +80V DC and must be pulled low (to
GND) for programming voltage to be applied to the PROM.

When pulled low, R/W initiates a 2% programming duty cycle for writing
to a 1602 or 1702 PROM (150 millisecond cycle time).

When pulled low, RW A initiates a 20% programming duty cycle for writing
to a 1602A or 1702A PROM (15 millisecond cycle time).
