The ASCII Corporation R800 was a fast 16-bit processor used in MSX TurboR computers; it was software-, but not hardware-compatible with the Z80 (signal timing, pinout & function of pins differ from the Z80). Zilog's NMOS Z800 and CMOS Z280 were 16-bit Z80 implementations (before the...
The Z80 pinout shows just how simple this is to hook up and at least test PC increment on NOP instructions. Hooking up some LEDS (with resistors!) to some low address bus lines, powering it with USB 5v and also fixing some of the other status inputs to 5v – they are active low i...
Since I wanted a small package, the Z84C15 was a natural, as that's got the CPU core, CTC, SIO, PIO, clock generator, etc all on chip. Using the PIO would be a nice way to interface to the IDE controller, but I hadn't seen such an implementation yet. Typical designs I've seen...
P5 is the floppy interface connector. It uses PC compatible pinout. When using a PC floppy cable with a twist, Drive A (ID 0) is the drive after the twist and Drive B (ID 1) is the drive before the twist. When using only one FDD, either a twisted cable can be used, or the BI...
