Hi Craig,

I've just made an offer o= f $100 for your memory expansion card on eBay.=C2=A0 I want a couple of oth= er items from you which I will pay for separately. This arrangement would e= nable me to get the items with reduced customs duties/taxes, which is alway= s interesting.

I have a question regarding the v1.= x CPU card and the memory expansion board. If I remove the RAM and EPROM ch= ips from the v1.x CPU=C2=A0 board, can I use the memory board to define a R= AM/ROM map to make the v1.x CPU look like a v2.x CPU?
