Hi everyone,
I'm new to this great forum and was hoping to get some help on getting an Apple II Europlus working that I recently aquired.
It initially did not turn on at all so stripped down power supply and after replacing damaged capacitors, bridge rectifier and fuse, I now have power.
When I turn it on there is no beep but there is just a scrambled display as shown in image.
It looks like there has already been some work done on this motherboard previously as there is a machine pinned IC socket used for the 6502 CPU.
On the back of the board there are two wires. Not sure if these are also added?
I have some basic soldering skills and and a multimeter and hope I can get this working. Would appreciate any help or suggestions on where to start.
The motherboard number is 820-0044-C
Hi,
it seems a RAM issue, check the ram IC
Thanks for reply - I have already tried differnet RAM.
I think there may be a problem with Databus or Adressingbus. I'm waiting for some replacement parts to test.
I've been following this guide here which has been very helpful: http://www.appleii-box.de/D04_resurection.htm
Will update if I have any success with this.
