please test this:
a) jump to basic
b) eject disc "D"
c) RANDOMIZE USR 15619:REM:*"d:" - call tr-dos, switch to drive "d:" and return to basic with message "R Tape loading error, 0:1"
If I use tr-dos 6.11e with ramdisc support:
a) jump to basic
b) RANDOMIZE USR 15619:REM:*"d:" - call tr-dos, switch to drive "d:" and return to basic with disable interrupt = stop CPU in ZX rom at HALT instrustion.... Why ?
