A few years ago there was a "Extreme" Micromite I think ? 100 or 144 pin at that.
Based on a pic32MZ EF 2048 I think. At 200 Mhz and heaps of memory etc the hardware is still reasonable but pricey. Is there a MMBasic for it ?

My impression is, there are no hardware suppliers active ?

AFAIK there is no-one selling MMX PCBs at the moment. Is the chip even available at a sensible price now?

@ zeitfest, if you are looking for MM.extreme I may have something lying around, I used to build up everything going to give me something to do. I know I built a couple, I will see if I can dig them up.

Many thanks ! (edited) although, I am not trying to get boards.
The reason I asked was that I designed and built a small pcb pcb for the pic32MZ some time ago.

It runs ok and I am pleased with it, it wasn't specifically designed as a MMX / eXtrem platform but looks like it runs it OK using alternate serial io pins.
So I am wondering if it worth a final tweak to connect the standard io pins, which should make it ok for MMX.
I might do it anyway as an exercise, but I doubt it will go anywhere.

Most projects here seem to go the same route : someone has a good idea, invests time and resources, puts it on TBS, maybe Silicon Chip puts it "design ideas" section...it then gets steamrollered/superseded by similar aim projects by people with apparently infinite resources, and a month or so later there might be a kit project in SC, at a kit cost that quite deters people, or no supplier at all. That then bypasses and obliterates any real commercial or mindshare future of the original project...Net effect, backward.

There are a wide range of MMX PCB designs 144-pin, 100-pin, 64-pin posted on TBS but they all suffer from the fact that the uP chip would need hand soldering and this is perceived as too difficult by many

If the MMX was to be seriously revived then a PCB design with a proper BOM and CPL that could then be manufactured by JLC would be a pre-requisite. Just posting gerbers doesn't solve the soldering issue.

Then you have to ask why? The STM32H7 is twice as fast as the PIC32MZ for the same price. The STM32 IDE/Compiler is free (the PIC compilers are expensive) and the PIC IDE is much harder to use. I did bring the MMX source up to a reasonably compatible and modern version (5.07.01b5) but don't intend to invest more time in it.
