Hello Dmitry and Sergei!
Thank you both - after two weeks of dead FTPs and empty Wayback
captures, this is the first time anyone has pointed me at an actual
file.

It arrived safely and is in my collection now: SV20P.XMD and SV25P.XMD,
both 524416 bytes, with KN_SDL.DOC, all dated 5 June 1997. Not the 0.F
I was after, but it is the first real KN_SDL anyone has been able to
show me, and those 1997 timestamps say it is the original rather than
something repacked later. Thank you.

True, and mine has been saying so all week.

Something went wrong with that upload. The link answers 200 with
content-type application/zip, but the body is zero bytes. The file is
empty, and catbox itself is up. If you still have it, could you check
and put it up again?

That is very interesting to me. If you do not mind, I would like to
call it one evening - it would be a far better reference point than the
transatlantic path I have been measuring.

I do not expect firmware to fix a missing common clock.
Reading KN_SDL.DOC, I find a direct path into the DSP:
ATGhhhh single-word DSP command
ATGhhhhhhhh two-word DSP command with a parameter, in hex
atg0012xxxx tone generator, xxxx = Hz*4
ATGXhhhh/ATGYhhhh DSP command 99, four nibbles from the parameter
and receive levels described as a linear value in internal DSP units,
7FFF corresponding to zero on S39. So, as I have too much free time, I
want to fiddle with it.
I am genuinely curious: did these historical modifications actually
touch the DSP firmware itself, or only the supervisor around it?
Thank you again, both of you.
Best regards,
Grzegorz Worona (kombos)
