Hi,
For my 65C02 computer build project I need to have an SPI interface. As I also have many other things to occupy my days and evenings I'd rather not have to reinvent the wheel. I have seen, and I like, Daryl Rictor's implementation of a flexible SPI interface using an ATF1504 PLD. I contacted Daryl but he is unable to help with programming or supplying devices at the moment.

Before I attack yet-another-learning-curve (I don't have a suitable programmer, I've never used these devices...) I wondered if anyone out there - preferably in Europe to reduce P&P - could program one or two of these chips, from Daryl's files, for me.

The price of the chips from good suppliers (Farnell, Mouser...) is around the 10€ mark. I can reimburse for 2 new chips +P&P, some time and, of course, P&P for the delivery.

Thanks, in advance,

I may be able to help you. Which package are you planning to use? Also, which speed grade do you want? I think I have some new, 10ns, 1504s in PLCC44.

Hi,
Daryl doesn't seem to specify the speed anywhere(*), and the PLC44 was what he used - so I'd say that that's just perfect !
If you'd like to pm me, we could talk business! Thanks very much.
