Well done Robert, lucky find! We should start an owners club :-) I got a mint one last year as featured on Bil Herd's web site http://c128.com/commodore-c232-32k-ted-courtesy-rob-clark which didn't work either when I got it. As Steve says, the most common culprits with 264 machines is the CPU (7501/8501) or TED (7360/8360) although in my 232 it turned out to be the MOS 7707 own brand MUX's that were at fault. I replaced them with stock 74LS257's and it now works great. I also I have a couple of spare CPU's if you need them. I can also provide you with a diagnostic kernal which I hacked together which can help you identify RAM and I/O problems. http://inchocks.co.uk/commodore/Diag264/HTMLManual/Diag264.htm Rob On 02/05/2012 22:00, Robert Sprokholt wrote: > > Today I got a couple of Commodore 232's.
