Title: Odd Question About A D80 Cpu
Post by: pooboy_92 on August 17, 2011, 06:54:50 AM

I know this isnt amiga related but I figured this is one of the few places this might get answered.  I have started to create a "Z80" computer and while looking for parts have stumbled across an old computer with what is marked as a  "D80" processor.  The only information I have found is this link

I am very interested in any information on it as I am still hunting for ram and things of that nature and this cpu appears to have them built in.

Any help is welcome and again im sorry for being so off topic but I need some help here, thank you.

Thank you for the quick reply.  This is exactly what I was looking for, the odd thing as as i read through this it says that they were used as slave cpus, but it was the only cpu on the poard and the computer was funtional before it was rained on oops.  So it just interesting what you find in your old parts sometimes.

But Anyway again thank you :roflmao:

If you could post some pictures of the full board then it might be possible to verify whether it was the only processor on there. It was designed to be used as a microcontroller & while it's possible to use that as the only processor it would be rare (although the magnavox odyssey 2/philips videopac control used an 8048 microcontroller).
 
You can tell if the program for it is internal by checking whether pin 7 is grounded or connected to vcc (? 5v).
