I wrote one 1985 as a DOS-extender,
but we had no internet so it was never published.
you may find a lot of later attempts from many sources now:
"HEX2BIN" or similar names with .ASM,.OBJ,.COM or even .EXE.

The 'problem' with debug output is that it has address prefixes and
display values at the end that need stripping out to get pure hex.

I could post code in hex, if that's more acceptable - it's just easier
for me to just CnP a debug dump.

I did hex2bin and v versa a while back; OK I'll revisit it to have a

Just Hex2Bin for debug typists!

(Is OK up to 62k, I think, might have problem with larger files if size
odd, I haven't tested it- prog desn't allow for hex pair to be split over
read boundary)
e.g.
hex2bin <hex2bin.hex >newh2bin.com
I *think* one can do
debug hex2bin.com
e100 <Paste hex string>
rcx 34 (check!)

(might be an input limit in debug, if so do CnP in smaller bits)
could work, but I'm afraid there is a much smaller size limit.
Smaller than linelength?! Ah debug's 'E' command must have separated hex
pairs. Just for you:
debug hex2bin.com
