This is where it's going, an old STM. Note the spring clip on the MMU, this needs to be removed!

MMU board in place - difficult to make out, but it won't fit with the MonSTer board in place

So, with the MonSTer popped out, I tried to fit it, but DISASTER! I has the pins set one too far back and my excitement to fit it, I pressed so hard that the back two pins popped through. I thought this would trash the board, but a very careful re-solder seems to have kept it alive, a lucky escape!

Bootup RAM test looks good ...

And a few runs on a proper RAM tester also look good, so happy days
