I never got the serial cable to work to the simulator, BUT I have purchased a 3.5" floppy (yes, the still sell them for about $10) that can be used to transfer your program for testing. It's pretty much plug and play to your own provided lap top. I'll write up the transfer procedure and post it soon. The funny part is that while Microcenter still sells the drive, they no longer sell floppies. so a special thank you to Vintage Computers for loaning me a floppy. Cheers!
