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?
Thanks
Brad

Brad,
You don't type in S1 records at the monitor prompt. 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):

Thanks Brent. So when I hit the end of an 'S'
record line.. is it
just a Line Feed I need to go to the next? Or just type the next S
record right in behind it?
Also curious about how you type S records at the monitor prompt. I'm
reading and trying to figure out how to do that.
Many thanks!
Brad

Yes, the monitor just sees bytes coming at it, it can't distinguish
whether they're typed or coming from a host/machine, as long as the
byte sequence accords with the Motorola S record format.
You can formulate your own S records and type them at the monitor, too.

Another question if I may -- for a short TXT
loader file.. could I
manually enter the information contained therein with my terminal?
I'm just thinking for a quick memory test, etc -- it'd be six of one
half a dozen of the other in terms of time to hook up a PC terminal
and
send the file..
If I were to hit L to put the 6800 into load mode, could I then just
type out the contents of the loader file with the CT1024's keyboard?
