128 BASIC-compatible way of loading BASIC as code?On a 48K Speccy (or from 48 BASIC or USR 0 mode on a 128K machine), one can do a silly trick like this: [code];; load a 4000 byte BASIC program ld i…
Dunno if it would work, BUT- save all the system variables except the first 256 bytes that is the original printer buffer area. On the +3 (so I assume the 128 too), that space is used for paging the RAM, so yeah. Speccy 128 would act up a little. -

The attribute data actually begins at (base_screen_address+#1800), so if you're paging in the screens at #C000 this should in fact be #D800.
