Easy Z80 project on OSH Park - View and order the PCB. Easy Z80 is supported by RomWBW v2.9.1 and later. RomWBW includes BIOS, CP/M-80 2.2, Z-System, and a collection of utilities. It also should be possible to run FUZIX on this board. Easy Z80 uses an ATF16V8/GAL16V8 SPLD (U9) for address decode logic.

The Z80-MBC2 is an easy to build Z80 SBC (Single Board Computer). It is the "evolution" of the Z80-MBC (https://hackaday.io/project/19000-a-4-4ics-z80-homemade-computer-on-breadboard), with a SD as "disk emulator" and with a 128KB banked RAM for CP/M 3 (but it can run CP/M 2.2, QP/M 2.71, UCSD Pascal and others).

This companion programmer PCB should cost about $2 more when it is ordered at the same time as the CPU board from JLCPCB or other similar proto-board shops as shown in the Z80 Retro! - How To Order PC Boards video on YouTube.

The Z80-MBC2 has a multi-boot capability and can run CP/M 2.2, QP/M 2.71 and CP/M 3 (128KB banked memory supported), so you can use a very large amount of SW with it (e.g. you can easily find Basic, C, Assembler, Pascal, Fortran, Cobol compilers, and some of these are already provided in the virtual disks on the SD).

All the documentation needed to build the SSP (Standard Parallel Port) Adapter board (A240721-R270921) including schematic, PCB assembling guide, Gerber files for PCB production. PCB is 55mm x 60mm 2-layers.

2018年7月27日 · The Z80-MBC2 is an easy to build Z80 SBC (Single Board Computer with 8MHz Z80, 128kB banked RAM, RTC, Disk on SD, Basic and Forth interpreters, CP/M 2.2 and 3.0, QP/M 2.71, cross Assembler and C toolchains).

This 5 chip Z80 single-board “computer”, is a very simple Z80 based “controller” with 8255 for I/O plus a “Z50Bus” expansion connector. I created it to kick-start my Z80 experiments – breadboarding is fun, but sometimes you want the basics to “just work” so you don’t have to troubleshoot loose wires 🙂

The Z80-MBC2 is an easy to build Z80 SBC (Single Board Computer) with a SD as “disk emulator” and with a 128KB banked RAM for CP/M 3 (but it can run CP/M 2.2, QP/M 2.71 and UCSD Pascal too). It has an optional on board 16x GPIO expander, and uses common cheap add-on modules for the SD and the RTC options.
