[QUOTE="NOVICE, post: 7301"] I've decided to use surface-mounted cards for programming rather than gold wafers - as, thanks to this forum, I learn they dissipate heat better. I know they are both surface-mounted, but can anyone confirm C-cards and Q-cards are one and the same thing. Also I have a bunch of cards I used to use for D2Mac. Anyone know if any of the following might be of use for satellite or terrestrial digital: 1) Green PCB card with the chips PIC16C84 and eeprom 24C16. 2) Two gold wafers with what look like two parallel sets of three contact lines (ie six lines on the chip) 3) Two white wafer cards - one with six contacts lines on chip, the other with a much more intricate pattern It's probably a stupid question but if any of them are of use, will I have to erase their content before they can be used, or can you just rewrite over anything which might be on the chip already? I'm getting a Millennium 2000 programmer. [/QUOTE]
