iz8dwf | IZ8DWF gets mail #3! SIDs are coming! Lots of chips and how to test quartz crystals @iz8dwf | Uploaded October 2021 | Updated October 2024, 57 minutes ago.
Thanks to Julian, I got a whole lot of spare chips and a whole lot of SID chips! Now my REV. A C64 PCB is complete!
I've got also a few spare quartz crystals and I show a simple circuit to quickly test them.
