Does anyone know the I-O port addresses on the (genuine) IBM "GP-IB Adapter" card for the personal computer IEEE-488 interface? It has an NEC D7210 controller IC and seems to have a DMA interface and jumpers for address lines A13 and A14 which I presume allow a limited choice of I-O port addressing. Alternatively has anyone any fragments of freebie code to drive this beastie. Any other hints/kinks on using this card? This is for my own personal use computer, ham radio and instruments. --------------------------------------------------------------------------- Henry Black henryb@hpspd.HP.COM +1 415 857 6655 KK6JR,G4NOC Opinions are mine and not a statement by Hewlett-Packard Company
