WILLIAMS FIREPOWER

Oh dear, seems like a virus getting around at the moment - lol , would it be just easier to just replace CPU board as a whole (with chips), I have seen them around on net for $150-200 ?

Thanks Skybeaux, any chance you can sell me these chips as I would rather try changing these out first then trying to find someone here kalgoorlie to change socket out (I presume its soldered)

I don't think IC27 and IC24 are socketed from the factory so you would probably have to desolder/resolder these anyway.

Some of the original Williams factory chip sockets are notorious for failing, particularly the "Scanbe" brand of sockets, so I would still be inclined to check this first.

Swapping the whole CPU board is always an option but you would also need to swap over the actual firepower game roms from your board.

Jomac http://www.jomac.net.au/ in Perth do repairs if you wanted to send your board out or else several members of this forum also offer board repair services.

Just had C5101 socket replaced also and still no luck.

As Ken said, there are a couple of other chips which could cause problems in this circuit.

This is from http://www.pinrepair.com/sys37/index1.htm#battery
....there are two other chips involved in the memory protect circuit on sys6/7. On system6 that's IC27 (4071 CMOS) and IC12 (7808). But frankly it is very rare that either of these chips fail.

If you've got someone to help with solder work, you could try replacing these.  It's also a good idea to install a socket if you do decide to change them.

Thanks Stevesee, have purchased a complete board from Ken & will just get my one refurbished & put in cotton wool for the next 30 years - lol.

No worries.  Sounds like a good plan

Hey all, just to let you know that all is good in my world of pinball again after replacing the CPU refurbished board from SKYBEAUX (Ken), the world is now a better place again
