The regular S1 tape exists in a few places, yes use L to load tape. This
is the best practice.
Purely as an experiment I made a monitor script so I could run at a slow
speed so I could watch the screen as commands were entered. I can't
remember if it was because the load (L) was not working or if there was a
cpu card issue.
I thought as a first step, given at the time in the flow of the thread the
OP was having issues, my monitor script would be worth trying.

Yes, we've had that debate a few times.
AIR, it was decided that bottom-posting was the 'list practice'.

I
agree any
process that has no checksum will be unreliable. Whatever.. .
Let's say for now you have at least the monitor method until something
better comes along.
But as far as MIKBUG/SWTBUG goes, you also always have the "L" command
If the data in your TSC BASIC "M" text were
converted to S-record format
- a trivial programming exercise -
it would be easier (no delays required) (and more
reliable) to load into
the SWTP.
They're both ASCII text input, just different
formats.
I'm not clear why you resorted to the M-command method, was the TSC BASIC
data
not originally
in S-records? - that would be the standard format for
loading such
software into an SWTP.
