Re: New Apple II ethernet card for sale

["Vince Briel" <vbriel@comcast.net>]

Thanks Glenn. Before Rich rewrote his firmware for the CFFA I was trying 
everything to get it to work in a IIplus. I never tried a 6502A but was 
trying the 65C02 which have the extra instruction sets. This had a negative 
result in the IIplus making it unstable. I'll check my stack to see if I 
have an A laying around.
