Presents two versions of a modified LOAD command for the ZX81/TS1000 that copies ROM routines into RAM and adjusts addresses to run there. Version 1 (SAVE the UnSAVEable) enables backup copies of self-running programs by scanning for ‘S’ keypress then jumping to the SAVE routine. Version 2 (LOAD the UnLOADable) recovers programs from tapes with bad spots (dropouts) by loading as much data as possible before the silent section. Includes hex code for 1 REM statements and complete BASIC listings with step-by-step instructions.
