Hi all,

I have just purchased a second hand PCB50B Eprom Programmer to help me repair old arcade machine pcb's. The problem I have is that the 20 pin IC chip next to the parallel port (it's adjacent to the other 6 IC's) was put in back to front and has blown. The chip itself has had the details rubbed off of the surface so I don't know what the chip was - can anyone tell me what it should be? I'm not sure why this was done - the other 6 IC's can be read easily. Also, do you think it will still work even when I replace it? There are no other signs of damage to the board and the chips looks standard.

I have also downloaded '098d12' - is this the correct software?

Sorry if these are basic questions - eproms and their hardware are a bit new to me

Anyone? I think it's a 74HC224 which is a Octal bus interface but I just need to be certain before I order the new IC.

any help is great

Thanks EZoSat,

Just found some on the net - I'll order one and go from there. I wonder why the details were rubbed off in the first place?

I don't suppose there's a link somewhere to a schematic for the programmer? Would be nice to have something to follow if the new IC does not fix the problem.

EZoSat,

Just to let you know it's up and running - thanks for the information.

I did run into another problem that I solved. My parallel port had the wrong address as I installed a card I found on eBay in a spare port. The EPROM software looks for specific address (0x378 for example). The address for my card is D898. This link tells you how to get round the problem:

Hope this is useful to anyone who has the same problem
