+5v right into the regulator socket, but serial and microdrives are

that arrangement so it is of limited use! I'm open to suggestions on

to get a replacement transformer, or for simple designs for a PSU that
gives
the correct AC output too.
Hi Dave,
I hope your feeling better soon. You should be able to connect your ATX
+12V and -12V supplies onto the QL's +12V and -12V lines (IC36,37).
Check this as it is all from old memory, but QL spec is:
10 VDC 1.8A (LH pin looking at back of QL m/b connector)
GND - centre pin
16 VAC 500ma(?) RH pin.
The values are written on the bottom.
Both these voltages are unregulated.
I always thought 10v DC (and it was often 11v) was too high and the
reason for the hot 7805. 8V would be fine.
Dave - I *know* you are really ill, as you have been very quiet on Skype
