The primary components for Plus Too will be the 68000 CPU, RAM, ROM, maybe a microcontroller, and an FPGA containing all the simulated hardware and glue logic. For the FPGA, I’ve been doing some rough estimation of the number of…

Digging further into the Plus Too design details, the next systems to consider are the keyboard and mouse. I plan to use a PS2-type keyboard and mouse, since they both communicate with a fairly simple serial protocol that’s easy to…

I’ve been working through the details of the video and audio systems for my “Plus Too” Mac Plus clone, and things are beginning to fall into place. Here’s what I’m planning: Video The Plus Too will have a VGA output for…

Continuing my efforts on the Plus Too Macintosh Plus clone, I’ve started work on the design of the interleaved memory controller. The memory controller allows RAM to be transparently shared between the 68000 CPU and the video circuitry. The general…

I’ve been looking further into the idea of building a working hardware clone of a classic Macintosh, and I think I can do it. I’ve decided to target the Macintosh Plus for hardware replication, and am tentatively calling this project…

What would it take to build a working clone of an early 80’s Macintosh computer? I’ve been kicking around the idea of a 68000-based project for a while– a custom computer something like BMOW 1, but using a 68000 CPU…
