Sikor Posted February 10, 2009 Share Posted February 10, 2009 Hello!!! I bought Atari with build-in supra PCB. Can anyone identify it for me...? (see pictures). I cant load nothing via SIO with my SIO2SD, but - I think - that it is any flooppy or HD interface. O.K. On PCB is info: SUPRA CORP and number: 30-0021-1. Nothing else. On PCB is soldered NEC D8048C 901 (X1Z176-150) CHIP and one eprom. Anyone know what it is...? Maybe some schematics exist on the net? Best regards, Sikor.

Bryan Posted February 10, 2009 Share Posted February 10, 2009 Maybe it's a printer interface? Looks like someone embedded an external SIO device. Quote Link to comment Share on other sites More sharing options...
carmel_andrews Posted February 10, 2009 Share Posted February 10, 2009 could be their version (the original) of the hard drive interface they did Quote Link to comment Share on other sites More sharing options...
Bryan Posted February 10, 2009 Share Posted February 10, 2009 (edited) No edit button... It looks like the original connector was 36-pin (Centronics), so I bet it is a Supra/MPP printer interface. Whoever installed it used the smaller connector like the 850 does. Edited February 10, 2009 by Bryan Quote Link to comment Share on other sites More sharing options...
+Allan Posted February 10, 2009 Share Posted February 10, 2009 It'a a Supra Mpp 1150 Parallel Printer Interface. Allan Quote Link to comment Share on other sites More sharing options...
Sikor Posted February 11, 2009 Author Share Posted February 11, 2009 It'a a Supra Mpp 1150 Parallel Printer Interface. Allan Thanks for info. Anyone have schematics or simply pinout description from this interface? I must make a new cable for this Quote Link to comment Share on other sites More sharing options...
Bryan Posted February 11, 2009 Share Posted February 11, 2009 You can probably figure out the SIO lines by where they're soldered to the XE. On the left of the board is where the Centronics connector went, so you can just look up the pinouts for that (also, the 15-pin external connector may be wired like an 850 so that gives you another point of reference).
