Hmm, I have a Dragon 32 and a 64 - ISTR one of them
has two PCBs but the
other is all on a single PCB. Can't remember which is which, now; it's
been a long time since I've been inside them.
I've got a disk cart, floppy drive and OS-9 for the D64, but the machine
itself was unwell and I never did get the time to fix it. One day...
Wellll...all the Dragon 32/64 machines I have seen have 2 boards, a
power/modulator board and the main CPU board but I guess this is not
what you mean :) :)
It's probably the 32 that has 2 boards, the main cpu board and a little
stand off board with some of the RAM on it. I believe that the reason
for this was that the 32 was initially designed to be a 16K machine, but
then Sinclair announced the 48K spectrum and the design was hastily
updated to add another 16K on the addon board.
