16-bit 6502 replacement bulk order : PCB schematics
Browsing through the discussion at 6502.org 's forum can be tedious, and
Daryl doesn't read these newsgroups, so here is his original post on
6502.org:
"After several months and many more revisions, I've completed laying out the
traces for the converter. I still need to clean it up - straighten some
traces, add 45 deg bends on the corners, check spacing around all pads and
vias, etc.
I added to the schematic. There are two jumpers. J2 allows you to select the
gate for the 74x245 and J3 selects 2 inverters or 4 inverters as inputs to
the AND gate.
Check out the schematic, layout draft, and expressPCB files on my web site.

Estimated cost for 10 boards would be $200. ($20 each)

and
"The clean up is complete and the design is ready.
I am willing to place a bulk order for these boards. We'll need a minimum of
10 boards in order to get the price down to $20 each. More boards would
bring the price down lower. I currently have requests for two. These are
four layer standard boards produced by ExpressPCB.com.
You can email your requests to me at 65c02@softcom.net
Please note: I was asked to help design the board and used information from
others to create the schematic. I have not tested it myself and cannot
promise that it will work. Please look over the schematic and my layout
before you decide to order. It can be found here:
