Last call for expressing interest in a bulk purchase of SBC-4P boards and/or daughter boards.
I have based the memory expansion on Garth Wilson's memory module. Since those are not quite ready, I have not been able to test them or test the bus loading/max clock frequency parameters.
With three daughter boards, I can run at 12MHz. 10MHz might be a better recommendation for more safety margin.
Here is an overview of projected costs:
10 SBC-4P boards - $40 each
20 SBC-4P boards - $26 each
Parts for the board $60-$80, depending upon quantity discounts
Dau-Term daughter board - $15 - $20
Parts for Dau-Term - $20 - $32
Dau-IO1 board - $15 - $20
parts for Dau-IO1 - $20 - $28
It would be best to contact me via email so I can keep track better.

This system can support developement in assembly, EhBASIC, CC65, and eventually some form of Forth.
My website has some preliminary info.

Feel free to ask any questions also.
Thanks
