Okay this is where I was getting a bit confused -- I had gotten the impression that S1 records were essentially what was punched out on paper tape and that on loading back in, the teletype/paper tape reader was simply typing all this in as if someone was sitting there. Looking at your TSC Basic file I see it invokes the memory examine and change function with the M and then starts at an address and just keeps going?
So when you had a program saved to a tape, these would have been S1 records encoded in Kansas City format? Is there a large collection of these loader files somewhere? Or like a definitive list of major software developed for the 6800? I'm hoping to learn more on how to program these things -- I'm assuming there was an assembler people used rather than just modifying memory addresses?

If anything you'd want to download a text file that simulates monitor commands to load memory, but it's a lot slower. I haven't been reading all of the posts in this thread, but have you tried following something like the instructions here to download a tape, I have documented how to use a terminal to download TSC BASIC into an SWTPC using a laptop serial port (or USB to Serial): http://vintagecomputer.net/browse_thread_record.cfm?id=416&tid=2 b On Tue, Aug 16, 2016 at 12:55 PM, Brad H < vintagecompu...@bettercomputing.net> wrote: > Thanks Brent.
