Ah. I'll have to get the old laptop out of hiding then. :-)
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.

xc3sprog will do it with appropriate cable. Or the Raspberry Pi trick that's demo'd around various places -- usually in connection with the Terriblefire boards.

Code: Select all

xc3sprog -c jtaghs2 -p 0 -v <firmware.jed>
for my cable.
