Help! Hooking up Epson/Practical Peripherals Parallel Printer Cards! I need pinout info on parallel printer cards to wire up a cable to my Olivetti Praxis 30. I came across two parallel printer cards that I have no idea as to how they are pinned out. They are supposed to utilize the same cable and are (1) Epson standard, and (2) the Practical Peripherals Micro-buffer printer card. Both cards have the same pinout configuration, and by tracing out the foil runs, I was able to ascertain that the following pins were probably correct: Epson & Practical Peripherals Printer Cards ------------------------------------------- Printer Card Interface Connector: Pin Assignments: ------ 1 | o o |2 1 - (don't know) 2 - Ground 3 | o o |4 3 - Data 0 4 - Ground 5 | o o |6 5 - Data 1 6 - Ground 7 | o o |8 7 - Data 2 8 - Ground 9 | o o |10 9 - Data 3 10 - Ground 11| o o |12 11 - Data 4 12 - Ground 13| o o |14 13 - Data 5 14 - Ground 15| o o |16 15 - Data 6 16 - Ground 17| o o |18 17 - (don't know) 18 - Ground 19| o o |20 19 - (don't know) 20 - (don't know) ------ The below are the pinouts on my Olivetti Praxis 30 interface jack. I assume that the standard pinouts applied, but I want to make sure before I wire it pin for pin and blow up my IIgs. Olivetti ByteWriter Input Jack ------------------------------ Olivetti Interface Block Pinouts: Olivetti Pin Assignments: ------ 1 | o o |2 1 - Strobe (Inverted) 2 - Ground 3 | o o |4 3 - Data 0 4 - Ground 5 | o o |6 5 - Data 1 6 - Ground 7 | o o |8 7 - Data 2 8 - Ground 9 | o o |10 9 - Data 3 10 - Ground 11| o o |12 11 - Data 4 12 - Ground 13| o o |14 13 - Data 5 14 - Ground 15| o o |16 15 - Data 6 16 - Ground 17| o o |18 17 - Busy 18 - Ground 19| o o |20 19 - +5 volt out 20 - Busy(Inverted) ------ So the bottom line then, is does anyone out there in AppleLand wanna part with the pinout wiring configuration for there two cards? Also, the Practical Peripherals has a six position dip switch that I have no ideas as to just what these babies do. Any help on that item would also be appreciated. +-------------------------------------+ | uucp: crash!pro-simasd!pro-pac!tomj | | Tom Jenkins (808) 422-6224 | | 4385 Keaka Drive | | Honolulu, Hawaii 96818 | | "What, me worry?" | +-------------------------------------+
