I have a Dec LA50 I would like to connect to my AT clone (DB9) but I don't have the correct pinouts. I tried DEC forum on Cserve but it only has the pinouts for an XT (DB25) connection. Can someone out there help? srm@topaz.rutgers.edu srm@remus.rutgers.edu myers@andromeda.rutgers.edu

Cable connections for connecting LA50/100 to (ugh) IBM PC & XT compatible computers. LA-50/100 AT-9 pin AT-25 pin TD 2 2 RD 3 RD RD 3 3 TD 2 TD GND 7 5 GND 7 GND BUSY 11 8 CTS 5 CTS DTR 20 6*DSR 6* DSR 1*CD 8*CD 4*DTR 20*DTR * Some AT machines may need to have DSR,CD and DTR tied together. The Conpaq 286 does not, the Tandon PCA does. You must add the following conmmands to the AT AUTOEXEC.BAT file: MODE COM1:48,N,8,1,P MODE LPT1:=COM1: Set the dip switches on the LA50 Switch Pack1 (SW1) 1 2 3 4 5 6 7 open open open open open close close Switch Pack2 (SW2) 1 2 3 4 5 6 7 open open open open open open close This option provides hardware handshake with the RESTRAINT mode (busy/ready protocal) The RB uses x-on, x-off. This info was compiled by Shurlo Tooker from the notes and personal experience of Kenneth LeFebvre, Shurlo Tucker, and Fredric Schuster. The information was obtained from The Hitchikers Guide RB Fido BBS. I have no direct knowledge to the accuracy of the above information, and make no claim of application to any use.
