Subject: circuit diagrams for the VT78

Hi,

Does anybody happen to have circuit diagrams for the VT78? The power supply
is bust, and I'm having trouble fixing it because many of the parts are
labeled in an unconventional (for me) way. Since the power supply is
switchable for 110V and 230V, I assume they used the same one for models
sold in the states. If anybody has access to these diagrams and could send
me photocopies (postage and packing will be paid) or if anybody could give
me some pointers as to where these could be attained (DEC here wasn't very
helpful) I'd be grateful.

  TIA,

  Ronald

Try Jerrasic Park - this thing is a real dinasaur

Or try a vt100 print set, or vt5x...

The power supply on a VT78 is different from the power supply on the VT5x.
The VT52 has a large transformer in the "printer" area which, presumably,
had to be moved to put the PDP-8 in there. The VT78 has a power supply
module in the back of the terminal.

I have a print set for the VT52, but it certainly did _me_ no good when my
VT78's power supply decided to become a paperweight.
