Hi All: Is there anyone out there who might have a copy of the MVME410 users' manual? I've spoken to my local MOTO sales office but they say its too old for them to have records on. Even a poor copy is better than no info at all. Worst comes to worst, does anyone know the parallel port pinouts? Thanks in advance Rich Knowles knowles@fnalo.fnal.gov Fermilab

Some offices still have that manual, but someone took our file copy in your local office and failed to return it. Rather than calling all over the country to find someone willing to stand at the Xerox machine, here's your pinout: Connector J1 Pin Signal Descr 1 PXCB2 INPUT PRIME low lvl output, clears print buffer and inits dvc 3 GND 5 PXCB1 FAULT - low lvl in; paper empty, deselect, etc. 7,41,45,49 Reserved 9 PXPB7 11 PXPB6 13 PXPB5 15 PXPB4 17 PXPB3 19 PXPB2 BUSY - input indicating printer cannot rcv data 21 PXPB1 OUT OF PAPER - hi lvl in 24 PXPB0 SELECT - hi lvl in 25 PXPA7 PD8 data out from PA7 27 PXPA6 PD7 29 PXPA5 PD6 31 PXPA4 PD5 33 PXPA3 PD4 35 PXPA2 PD3 37 PXPA1 PD2 39 PXPA0 PD1 43 PXCA2 DATA STROBE - output clocks data, active lo, 1 us wide 47 PXCA1 ACK - low lvl in, indicates character ready or end of op'n 8 No connect All other evens Ground Note that the descriptions are based upon use of the parallel pins to drive a Centronix-style printer port. Based on the above and a simple program to play with the PIA, you should be able to nail down everything pretty simply. The pinouts on the other connector are the same, but, obviously, attached to the other PIA. -- [ Michael Bodine, michael@chg.mcd.mot.com, Dial: (708) 576-7840, FAX: x8875 ] [ Motorola TSD; Loc IL38; 1100 Woodfield; Suite 334; Schaumburg, Il 60173 ]
