Did I watch the FCukup this weekend? Of course not! Instead, being an uber-geek I built this Z80-MBC2 board and revisited the groovy 70s computing era. Definitely a nostalgic trip down computer memory lane.

Z80-MBC2: a 4 ICs homebrew Z80 computer

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), 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, Collapse OS and Fuzix too). It has an optional on board 16x GPIO expander, and uses common cheap add-on modules for the SD and the RTC options. It has an "Arduino heart" using an Atmega32A as EEPROM and "universal" I/O emulator (so a "legacy" EPROM programmer is not needed). It is a complete development "ecosystem", and using the iLoad boot mode it is possible cross-compile, load and execute on the target an Assembler or C program (using the SDCC compiler) with a single command (like in the Arduino IDE).

The RetroComputing folder is looking good, after a bit of a reorganization and some icon Photoshopping.

I wrote two programs for clearing the screen on CP/M-80 and CP/M-86, one in Intel 8080 Assembly for the Z80-MBC2 homebrew computer and the other in Intel 8086 Assembly for the V20-MBC:

Two CP/M programs to clear the screen

Sometimes experimenting with the Z80-MBC2 and V20-MBC homebrew CP/M computers leaves the screen garbled or in an unusable state, usually ...

The cool-retro-term vintage terminal emulator is, well, cool:

Here are some CP/M Plus programs in cool-retro-term on a Z80-MBC2 homebrew Z80 computer, connected to my Chromebox via a Minicom session on Crostini Linux.

The only issue is coo-retro-term sets the EN keyboard layout and doesn't recognize my IT keyboard. Any fixes?

I tested the Beagle Term terminal emulator with the Z80-MBC2 and V20-MBC homebrew Z80 and Nec V20 computers. It's a Chrome packaged app with good VT100 support.

The screenshots show Beagle Term on my Chromebox running the Catchum and Ladders games under CP/M Plus on the Z80-MBC2, and WordStar and the command processor under CP/M-86 on the V20-MBC.

Beagle Term

Beagle Term is serial terminal emulator.

The two homebrew CP/M computers I use and love have logos that give them personality.

The Z80-MBC2 Limited Edition features a "Z80 inside" logo similar to the iconic Intel branding. The logo of the V20-MBC Black Edition, a two-flavor ice cream cone, is a nod to its Nec V20 chip with the 8080/8088 dual mode.
