212 , 288 , 289 multi programmer card connector wirings.
dataio 212 288 289 resources
Here is the card connector and the chip socket.
The pins in the EPROM sockets are connected the same as the ones
on the card except both /CS pin 1 and 49 I think they tell machine it has card
plugged in and enables the /CS for the 27512 chips on the card .
I can only guess it uses the on board chip sockets otherwise.
I think using a ribbon cable plugged into a programmer and one of the sockets
would connect most of the pins of the card to the programmer.
/CS would need to be connected to the chips one at a time and some measure
to prevent buss conflict by preventing+5V power to enter the machine.
Possible to lift the VCC pin of the chips and connect to pin 28 of ribbon
cable with pin bent out from socket on main board.
Something similar could be done with the /CS pins on the ribbon cable but
no need to lift the chip pins most likely.
I have made a pin list for the ROM card of the 212 Data I/O.
It may be possible to copy the data using a ribbon cable to the internal 28
pin EPROM sockets.
Then it looks like somebody could program 2 of 27512 eproms to use
instead of the card.
Part # 324-1800-008 V5.0 for socket module with 40 and 32 pin EPROM
module part # 715-2035-001.
Power would need to be isolated from main board and applied to eproms on
the card only to avoid buss conflict.
/CS would need to be jumpered to each eprom as data is read from the OTP
27512 chips on the card.
