In lieu of having the "1 SYS 1037 BASIC" line, you could formulate a MWBASIC'USR() statement.
For the PET Timer, you might be able to use the 50Hz VSYNC pin mod and write an associated ISR (interrupt service routine)
Otherwise install a Z80 CTC for higher resolutions.
You can use the microbee PCG for the tiles.
The map and msg can be directly ported.
