I also tried CBM-PC with the 2031LP, the only drive with 75160/75161 AFAIK: no problems as well. IEEE-488 is a protocol and should be hardware independent. Same for RS-232. This enables me to connect a C64 to a PC and exchange data without the fact that a machine has to worry about what hardware the other machine is using. > It has a mode where six of the eight data lines are used as > outputs while the remaining two are used as inputs. When doing that then the SoftBox is not using the IEEE protocol anymore because IEEE requires the 8 data lines either input or output and not using a weird mix. And on its turn you cannot blame the CBM-II not understanding this weird behaviour. -- Kind regards / Met vriendelijke groet, Ruud Baltissen www.Baltissen.org Message was sent through the cbm-hackers mailing listReceived on 2017-05-25 13:01:25
