Homebrew PCBs

Give me a snail mail address, Don  and I'll send you a copy of the CD. 
I'm temporarily in Canberra at present and using pre-paid nextG, so 
bandwidth is too limited to try emailing it.

The manual gives the switch settings and also a good description of the 
DXY and RD-GL Command sets. I'm not sure whether they are all common to 
the DXY-800 although I did come across a review in a 1984 magazine when 
I was clearing out my old shack a month ago that suggested they were 
then newly released on the market at the same time, with the 800 
offering a slightly cheaper, single pen option. There was some coverage 
on this group back in January though that suggested the DXY-800 had more 
in common with a different model.

Supply is a little unusual in that it supplies 9VDC at 500mA and 35 DC 
at 700mA supposedly, although mine supplies 15VDC and 40VDC, which 
combined with its weight suggests that it is a simple tapped- secondary 
transformer and rectifier supply, without regulation.
