Are you reading this Atari? Perhaps we should petition Atari about this. >By the way how big is the ROM space of the 1040STE? I think this is the situation on ROM size and location:- Machine Size Address TOS Version ------- ---- ------- ----------- ST,STF,STFM 192K $FC0000 TOS 1.0,1.2,1.4 STE 256K $E00000 TOS 1.60,1.62 Mega STE 512K $E00000 (?) TOS 2.05 TT 512K $E00000 TOS 3.00 (?) Note however you should *NEVER* rely on the address. You should get the address system header at $4F2 and work from that. I guess the STE could be hacked to take 512K of addressing. Maybe the MMU craps on that idea. >Harold van Aalderen (hvaalde@cs.vu.nl) +----------------------------------------------------------------------------+ !
