If interest is sufficiently small, I suggest doing a run of prototype boards at www.33each.com or equivalent. The PCBs will be more expensive ($33 each plus shipping) but will be of top notch quality. No gold fingers though.
For boards like small run Zetas, ParPortProps, S-100 uPD7220 GDC, S-100 Utility, and S-100 VDP it makes sense to use the prototyping service until there is enough group interest to warrant a production run of PCBs. Regardless, I would love to see the S-100 uPD7220 come to pass and the S-100 Utility board as well.
Thanks and have a nice day!

Andrew has uploaded the EDA files for the uPD7220 GDC this afternoon, if you feel inclined to do a production run then put me down for 1 board
just for curiosity value. It might be worth considering a smaller run of 5 to 10 boards as this board has failed to spark sufficient interest for a production run
before. looking a previous forum posts for the uPD7220 GDC it would appear to be a descendant of the ECB uPD7220 graphics board interfaced to the S100 bus and is ripe for testing.

It does seem like it would be an interesting board for an S100 system.
With almost all of the work done it would be a shame not to go through to completion.
Unfortunately I don't have enough of a system together to help in testing, but I can chip in a bit
for prototypes. I'd also be willing to handle the production run if we can get takers for at least
20 boards, if that would be helpful.

I can definitely see chipping in at least some of the cost. I find the uPD7220 GDC interesting as several business class CP/M systems used it for graphics (DEC Rainbow, QX-10 etc.).
