MicroCore Labs

Introducing the MicroCore Labs MCL8080+ The MCL8080+ is an Intel 8080 emulator written in C which runs on the ATTiny85 microcontroller.

I would like to share an update for the MicroCore Labs MCL68+ project first introduced here: https://microcorelabs.com/2023/10/26/mcl68-motorola-68000-emulator-2/ I am happy to say that it is now able to completely boot and run the Macintosh 512K!

I was able to run a KayPro II using the MCLZ8 as the CPU.

The MCL_PetDoctor is a suite of diagnostic tests which run on the MCL65+ board which is a drop-in replacement for the 6502 CPU which can emulate a cycle accurate processor along with all all of the computer’s RAM and ROM.

I recently acquired and restored a Commodore PET 4016, so I thought it might be fun to try replacing the CPU with an MCL65+ 6502 drop-in replacement board to see how it performs.

I got the MCL86+ running on the IBM PCjr by adding 8088 minimum mode support plus a few modifications to the PCB.

I picked up a IBM 5150 motherboard from the Silicon Valley Electronics Flea Market a a few weekends ago which appeared to be in very good condition.

The MCLV20_Max has integrated the BootRom from the XTMax project to allow booting from the MicroSD card.

The MCLV20_Max is a Teensy 4.1-based software-defined drop-in CPU replacement for the Intel 8088 used in vintage IBM XT’s.

XTMax is a software-defined 8-bit ISA card which uses a Teesny 4.1 microcontroller board that provides the functionality of THREE vintage ISA cards.
