Homebrew PCBs

Hi,

    I think everyone on the list should take a look on this link on the
"direct PCB plot section". Seem pretty much doable, even more for the
fortunate ones that have a CNC mill around. Regular size pens could be used.

Thanks, just added it to the "Links" area of the list.

If there is interest I will put up the HP G/L code on one of my web-
pages. HP/Agilent provides a little support for these old, workhorse 
products, but not much. I also have a "fix" for converting the Gerber 
output produced by Ultiboard to something which will plot on an 
HP7475 in minutes instead of hours.

The old serial plotters go for a few tens of dollars on EBay.

I think I missed something- what HPGL code are you
talking about?

I have a couple of those old HP plotters, both serial.
Thought that might be a good place to start for making
an engraver, use the electronics to drive beefier
drive transistors, steppers, and mechanics to move
something like a Dremel.

Hi Jack,

Yes!  I'd be interested.  I still have my HP7475 from '85, although I
use it only occasionally.  Laser printers do such a good job on
schematics now!  What "code" do you have?  I hate to see them piled up
as surplus, makes me want to take them home with me, and give them a
good home!

All things HPGL would be welcome!
