EEPROM Programmer V2.0 (sort of)

[dracosilv]

I decided to take a gamble-step and do this to my EEPROM cart:

I know I haven't added the proper 'Dongle' to do eeprom programming, but I could make said adapter.

From the first photo:

This photo shows the connections to the DB25 connector on the top of the board. From left to right:

Pin 22:Black: Ground
Pin 21:Red: +5v
Pin 18: Green: CR/W (R/W for the CPU)
Pin 13: Green: /BLK5 (Active when A000h to BFFFh are accessed)
Pins 9 to 2: CD7 to CD0 (CPU Data Lines)

From the second photo:

This photo shows the connections to the DB25 connector on the bottom of the board. From left to right:

Pins B, C, D, E, F, H, J, K, L, M, N, P, R, S: CA0 thru CA12 (CPU Address Lines)

So all the lines needed for a standard /BLK5 cart are there. I would just need to solder up an adapter.

Questions/Comments welcome/appreciated.
