Friendly fZ80 is a new, modern desktop computer that runs CP/M 2.2 and MP/M II 2.1, Digital Research's multi-tasking operating system for the 8-bit 8080 and Z80 microprocessor. fZ80 is built around a modern processor, uses a modern (VGA) display, modern keyboard, USB power and SD card storage.
As of 16 August 2026 these are updated hardware and continuous software development. Cabinet aesthetics and finish are improved. The manual has nearly doubled in size. MP/M operation is discussed including how to effectively set it up for daily use. Here are some construction photos.
The process to ready machines to ship took far, far longer than expected. The machines and code are "done"; the problem has been the "packaging". I travelled a lot in July, I have a nasty cold this week, and I will be travelling next week, and I was attempting to hurry to launch the eBay sale this week. Hurrying is never good. So I'll finish up copying files onto SD cards (slow!) this week and all will be finely polished and ready to go on the 17th. I apologize for the multiple delays. (And I am awaiting six (6!) simple spacers to assemble covers onto the last two units; parts arrive this week.)
fZ80 CP/M has a 61K program area; MP/M has 208K memory in four banks, capacious by standards of the day. The emulated Z80 has an equivalent clock speed of approximately 70 MHz, and passes all known Z80 compatibility tests.
Housed in a painted aluminum cabinet approximately 8" x 4" x 2", the rear contains serial and parallel port connectors with "IBM PC" pinouts, plus USB-C connectors for keyboard and power.
Use the links in the bar at the top of the screen for provided CP/M and MP/M software, hardware details, manuals and other documentation and features.
Here are a few simple videos of the fZ80 in use, to get a sense of what it's like to use; boot CP/M, run MP/M, multiple "busy" screen programs, an example compile, etc.
There is a fZ80 Operator's Manual and documentation for all of the software and hardware involved. A printed manual (5" x 8", 208 pages) is included with every machine.
CP/M and MP/M software is found at the Software link in the bar at the top of the screen. Machine firmware updates and process are available here.
I will post the eBay link and item number here in the first week of August 2026.
