Hi everyone, I have been going through my old boards, servicing the ones I had pending, which takes me to a Mortal Kombat 2 board.
I have the sound, main, and expansion, but the expansion memory needs work, when bought the seller seems to have misplaced the memory board outside in his shop, and one EPROM rusted over time, overall board needs some work. nothing serious that I can see on the traces.
I just want to buy every single replacement to have it in stock.
Already got:
EPROMs, sockets, caps, and axial resistors.
looking for:
- the 60pin header which seems standard 1inch length
- the 74actq244 seems it has a modern counterpart: https://www.digikey.com/en/products/detail/texas-instruments/SN74ACT244N/375910
Need help with:
The ones I am not knowledgeable about are the SIP resistor and the one highlighted in yellow, I went to Digikey, and filtered 10pin but no 4.7ohms shows.
is my understanding this is a SIP resistor: 9 resistors / 10-pin / 4.7 Ohm.
added a photo of the part. But all I can find is 4.7K, could this be a typo?
Thanks.
