I'm embarrassed to say my resources are still rather dismal and so I'm (begging) wondering if a fellow hobbyist may have a spare Z80 chip laying around that he/she would consider donating to me for an experimental project? Of course beggars can't be choosers but a 4-MHz chip in a DIP-40 or PLCC-44 package would be ideal.
I'd like to test a "pocket Z80" three chip 64K computer design which would include a serial interface and SDcard storage. I did something like this earlier this year (see below) after someone gave me a couple CDP1802 CPUs and I'd like to try and duplicate that success using the more powerful and more popular Z80 CPU.
Thank you all for your time and kind consideration.
I got most of my hobbyist components from eBay, including Z80 and other old chips like the 8051. Prices are reasonable ($5-$10 inclusive of shipping) too, although shipping is sometimes slow if the seller is in China.
Hmm, I recently rediscovered a tray of spare C64 custom chips since the 80's. The pins are starting to corrode. I had socketed a complete C64 including the RAM as a test unit for 'bad' chips. I used to keep extra 'good' chips that I got.
