Stern Solenoid/Driver Board - RevC

[Sinbad79]

Does anyone know where i can source a new U9 CPU Chip for the M-200?

[studley67]

if you need them in a hurry,i have all the parts for theese boards here.or i buy them from gpe greaplainselectronics

[Sinbad79]

Thanks Studley I'll call you later today for a chat.

Meanwhile, last night's effort was to replace all the components in the reset section of the board. Didnt think that was the issue initially but thought it couldn't hurt.....turns out it wasn't the issue and there is something else going on.

I think next step is to start swapping out IC's

[studley67]

what is that ram daughterboard contraption?

[Sinbad79]

No fkn idea

[studley67]

i am guessing it is doing the work of the old 2x5101 ram chips

[Sinbad79]

yea likely.
Probably an attempted fix by previous owner/operator who likely didnt have any 5105's laying around.
5105 below it is still there.

I guess what i need some of these chips to be swapped out to see if that helps - if i made the drive up to your place this weened, do you think we could get it running?

[studley67]

definitly mate remember i also have a galaxy

[Sinbad79]

Lifesaver!
I'll buzz you later on tonight - hopefully you're coherent and not drunk 

[studley67]

Don't worry about that just yet, you stil have the old sh&*t sockets on the board, first port of call is to replace them.
That add on board is to run a 6116 instead of a 5101

[studley67]

yes criss i also suspected that as he still has the 4 eproms installed

I'm powering up the board on the bench with a modified PC PSU, so connectors aren't the issue just yet, however that said, it's on my list of things to change.

criss is talking about the ic sockets
