4787Re: [solectria_ev] AMC320 repair
- Dec 8, 2008I would be interested in a circuit board / populated. Is there an estimate of the kit cost?
Thanks, Bill S

This is the schematic for the cable:
http://www.wolftron ix.com/amc320/ amc_i_cable. jpg
I use an old compaq laptop that still works and has a serial port on it,
it runs windows 98SE.
I could do a layout a circuit board for the adapter... but the cost at the
board house I use are:
$33.00 each, with a min order of 4 boards.
$33.00 for a panel (panel = as many boards as you can fit into 60sq
inches) + $50.00, with min order of 4 panels.
So its MUCH cheaper to just bread board your own, or just solder the parts
to a protoboard.
Unless a bunch of people want them. :)
