80 column problem
Image icon $_12.jpg23.64 KB

Got an Apple //e Enhanced Board Rev A. Machine runs great except I may have a bad 80 column /w 64k card. See Pic. I ran the self diags *RAM (0's and 1's). Take the card out and reran the diags System OK. The 80 column card is a 607-0103-K (jumperless). First of all has any one seen a card do that before? Next if it is the card do I get the same card or an earlier revision of the card /w 64k on it? My understanding is since I have a REV A board it can not do Double Hi-Res graphics but yet it can (basic command hgr2?) Need a little advice on this thanks.
