SAMP001 owned by Simon Goodwin
SAMP003 originally from Nev Young.
SAMP003 was used pre-release for debugging the ROM and DOS by Nev with Dr Andy Wright at MGT in Swansea.
The case is a mock up of the final design and has only a drive bay on the right hand side (as opposed to the left in the final release) and no ventilation slots at the back.
The SAMP003 keyboard is individual key switches with paper printed markings in the same font as the SAM Coupé Technical manual on a custom PCB. SAMP001 has got ZX Spectrum keywords on it's keys.
The SAM Prototypes were hand soldered by Bruce Gordon himself.
