Hi Siggi; Ah, I see. The easiest solution would be to change the value of RAMTOP in line 2020 to whatever value works for you. The upper 6K from $E000 upwards is reserved for a copy of the HRDFILE. So you could set it to anything lower than that. The only change is that you won't have as much memory...

Hi Siggi; I'm assuming your referring to lower ram? The areas used in lower ram are... 8000-14336 HIRES DFILE $2000-$3800 14337-15129 SCREEN MENU $3801-$3B19 15130-15979 MC PROGS $3B1A-$3E6B 15999-16389 FREE SPACE $3E7F-$3FFF 390 BYTES As you can see there are 390 free bytes remaining.

That look great, I'm envious!!! It's nice to know that programs can still be tested on the real thing. I have a ZX81 and T/S1000 with RAM pack, just no cables, power supply or B&W CRT TV.
