Just opened up another STM, besides the cool ram upgrade it has lots of patches going from the modulator to various places around the shifter. Anyone know why?

Well, you've solved the mystery of my 520SFM's memory upgrade manufactuer for me! It doesn't have the name on mine, merely the logo.
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.
