I have a cimnet BTR that Im trying to get working on a Ge 1050 mccm.The only info I have on this thing is the manual.The wienies at cimnet are refusing to help since im not the original owner-It came with the machine.It will load its config file and accept the mode commands.I suspect that its not putting any parallel out put.Any suggestions?Also,I also have a B&B serial to parrallel converter.The Ge needs a 12v parrallel to read info in the tape port,the converter puts out 5v,what would be the best way to amplify the 5v signal?
