Hi Are old parallel cards able to send AND receive datas? In others words can I do a LDA $CXXX to GET a byte? Are they any "standard" programming address for this type of cards? See you soon ;-) Babar Babar de Saint Cyr (France) LCD Apple 2c, WorkStation Apple2e, AppleTalkized IWLQ, 11.25 Mhz TWGS, etc... ;-)
