It's a little scary that I can recognize a lot of those instructions from memory, even though it's been 40 years since I first got my ZX Spectrum.
Of course more recently I've been doing a lot of z80-based CP/M retro-fun. But "62, xx" is obviously LD A,xx, and similarly the 205 is CD which is CALL.
Fun stuf, thanks for the post, you are indeed AWESOME.

"call 5633" at that which opens the IO stream given in A.
I thought that's silly, but uh, I did recognize the opcode for CALL as well. Turbo Pascal for CP/M allowed one to enter in-line machine code, but didn't offer an assembler...
