John believes the machine used for the ZX81 and ZX Spectrum ROMs may
have been smaller than the one used for the ZX80 ROM and with only one
disk drive, but it was the same blue colour. That's probably as close
as we're going to get to the specific models involved.

What is a decade amongst enthusiasts? The small, single disc version of the Zilog development system was called a PDS (personal development station) and was about half the cost. I bought one in 1977 (from memory it was well over £2000, a LOT of money in
those days - my father thought I was mad) and used it to develop ASZMIC and my other Sinclair stuff. I still have it in the loft, but I think I inadvertently threw out all the 8" floppies when I moved 13 years ago so it is not much use. It came with the
same software as its big brother, but only a separate single disk drive and a lot less memory.
