@exxos Good to see this moving again!

I've still got a blank H4 & H5B board on the to-do list (but I do have the old GLUE/MMU chips for them if necessary) so I will volunteer them as/when needed if that would help?

Ah reminds me I need to send you an H5 adaptor for that FPGA board @exxos so you can ditch the old STFM board and use your H5.

Cool. No rush. I need to figure out why my latest firmware doesn't boot up anymore :lol: :roll:

Looks like we have an FPGA MMU running on an H5. It's a little unstable at the moment as am just tuning it to work with the Phoenix Shifter but GEMBench runs ok. Most effort yesterday went into making the 7 Segment Display read as MMU. It's the important things :)

Looking promising.
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.
