Since I have some time to write stuff up, I am documenting wiring and usage of the Flash Attack cable (a PET-to-PET data cable), and am adapting it to the other 8-bits (64, VIC, Plus/4, etc.) This cable I have quite a bit of coding experience on, from easy BASICable send/receive routines to memory movers, (should adaptable to the other cable, since the I/O code is separate from the main routines.) I have notes that the Plus/4 Parallel Bus Pins are (a mess): PIN DESC: B Parallel Data Line bit 0 K Parallel Data Line bit 1 4 Parallel Data Line bit 2 (also 'cassette sense', unplug datasette before use) 5 Parallel Data Line bit 3 6 Parallel Data Line bit 4 7 Parallel Data Line bit 5 J Parallel Data Line bit 6 F Parallel Data Line bit 7 and the 'address' for the port is 64784 ($FD10) but I cannot find an entry for the cooresponding Data Direction Register which assigns the bits as input or output.... :/ Also on a side note, anyone have the B-128 Parallel Port and DDR locations, I assume the pinout positions are similar the the VIC and C64? -- 01000011 01001111 01001101 01001101 01001111 01000100 01001111 01010010 01000101 Larry Anderson - Sysop of Silicon Realms BBS (209) 754-1363 300-14.4k bps Classic Commodore pages at: http://www.jps.net/foxnhare/commodore.html 01000011 01001111 01001101 01010000 01010101 01010100 01000101 01010010 01010011 - This message was sent through the cbm-hackers mailing list.
