RXB Posted February 13, 2019 Share Posted February 13, 2019 I only suggested the CASSETTE port as this could be added to a single console for input and output to other devices besides just SERIAL like JOYPORT. I was thinking instead of Cassette to send it to a device chip instead thus work like Disk Drive storage. CS1 would be READ/WRITE and CS2 would be READ only. And they could be on same device with single toggle of on or off READ/WRITE Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted February 22, 2019 Share Posted February 22, 2019 And back to Arcadeshopper's comment on the existence of IEEE-488 cards, there are probably about 20-30 of them in circulation. I have a pair of them that I plan to use to interface a pair of TI computers to an IEEE disk drive at some point. . .I also have about 20 of the required TMS-9914s, so I could probably build some new ones on a Protoboard at some point too. . .I just have to test to see if the PALs are locked or not, as I don't think I have a complete description of the JEDEC equations for it. 3 Quote Link to comment Share on other sites More sharing options...
+FALCOR4 Posted February 22, 2019 Share Posted February 22, 2019 Here was a hair-brained idea from back in the 80's. Thought maybe using a DSR space and breaking out CRU bits might be cool, never finished it. Maybe I was thinking I could control the lights in our apartment or something..... :-) 6 Quote Link to comment Share on other sites More sharing options...

HOME AUTOMATION Posted February 23, 2019 Share Posted February 23, 2019 I agree... definitely hair-brained... I did the same thing... the schematics are on faded thermal paper... Mine was stand alone, using tone decoders driven by the sound generator... Abo. 106 outputs. 3 Quote Link to comment Share on other sites More sharing options...
