Re: wanted - an 8501 cpu

The 6510 substitute for the 8501 is indeed an interesting option ..but so far I have had no success contacting it's developer.
I tried leaving a comment/request to his blog ..but so far ..no response ?

wanted - an 8501 cpu

anyone know where I might obtain an 8501 cpu at a reasonable price ..
I recently restored 2 x commodore plus 4 computers ..and a C16 ..
Sadly I'm one cpu short ...
I can test them all by swapping the cpu over ...but it would be nice and safer to have one in each computer.

Re: My PET 4032 is dead

Now I have space invaders on my PET ..I figured it worth adding a small single chip amp powered from the 5volt rail... inside the case ..and doing the user port sound mod ..
It's very effective indeed..
