  I was rather covering my own back when some clueful
person points
 out that it is possible to make a GPIB interface using those chips
 (althoughI still can't see how ;-))

  I wasn't trying to 'get at you' and I
apologise if I gave that 
 impression. 
I didn't think you were 'getting at me'; looking back I should have
put a few   :-)   :-)  in my reply!

...
  I am firstly trying to find out what all the options
for the 380Z
 really were  -- my machine is rather cut down, and contains :  
...
  Z80 CPU (with 32K RAM)
 40 column VDU
 RAM expansion (32K)
 Hires graphics
 Floppy controller
 Terminator 
I'm going to have to dig my other 380Z out and record what's in that.

...
  Secondly I wanted to warn you against connected PET or
HP
 peripherals here, as the results would probably not be good for
 either the 380Z or the peripheral. 
I do have the standard PET IEEE peripherals, thanks for the warning.

...
  It would be interesting to figure out just what it
does. Feel like
 a morning with the TTL databook and a continuity tester? :-). 
When I get the time, I'll do this. I also thought I could scan or
photograph/scan the board and e-mail you a tiff/jpeg
