Hi
All,
?
I have
a thermal printer HP 5150A that requires a new character code PROM on the BCD
(Binary Coded Decimal) circuit card.? (The HP part number is 1816-0561.)
The PROM is type 74S188 which is a 256 bit memory organised as 32*8
bits.
?
I can
purchase the IC and I can work out the required bit map but I have no way of
programming the PROM.?
?
Anyone
know of a circuit for a suitable PROM programmer for this chip or could provide
this service for a fee?? All I can find on the net are references to EEPROM
or flash and newer chips.
?
Thanks
for any help,
?
