Do you have a source online for PDP-8 toggle in test programs, such as echo characters to/from the TTY and PDP-8? THe PDP-8e versions are different. I can probably figure some of it out, like I did with the chase the lights, but I am always up to make things easier.
I've used print and echo TTY tests on straight 8.
BSW is not valid for straight 8 so tests will give different results after BSW. IAC with rotate are also invalid but didn't see any in quick look. Don't remember seeing straight-8 specific toggle in tests.

Thank you for checking. Here is one I made from the assembly code found on wikiwand: 0010 / Set current assembly origin to address 10 STPTR, 7776 / An auto-increment register (one of eight at 10-17) 0200 / Set current assembly origin to program text area HELLO, 7000 / CLA CLL 7016 / TAD I Z STPTR 7400 / SNA 7400 / HLT 7500 / TLS 7540 / TSF 5000 / JMP .-1 5200 / JMP HELLO STRNG, 0310 / H 0345 / e 0354 / l 0354 / l 0357 / o 0254 / , 0240 / (space) 0367 / w 0357 / o 0362 / r 0354 / l 0344 / d 0241 / ! 0000 / End of string $HELLO 0000 / Default terminator
