›››››› HISPDROM.XMO›› This file is an overlay for the 800XL OS that will› enable ICD modified 1050's to run at high speed without› SpartaDOS. You need to load the XL OS from address $C000 to› $DFFF into memory at $4000. Overlay this with HISPDROM to› create the modified file. The area in the OS from $E000 to› $FFF is not altered and can be used as is. Burn an EPROM with› the new OS and plug it in - you now have high speed I/O any› time you go to a modified drive.›› ***** I used locations $24A-$24D as flags. If this causes a› problem on any of your favorite programs, it can be moved.›› I used a ProBurner ( Thompson Electronics -- GREAT!! )› to produce my EPROM:› a. Move 800XL OS $C000-$DFFF into $4000-$5FFF.› b. Go to DOS.› c. Load HISPDROM from D: - this will overlay parts of› $4000-$5FFF.› d. Burn EPROM from $4000 at $0000 to $1FFF in chip.› e. Move 800XL OS $E000-$FFFF into $4000-$5FFF.› f. Burn EPROM from $4000 at $2000 to $3FFF in chip.›› Other types of programmers should require similar steps.››› BOB WOOLLEY [DAD] [75126.3446]›››››››››››››››››››››››››››››››››MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
