|  Re: emulators bug
Thanks. Try to run Turbo Assembler 6.0 (converted from C64 by csory) notes. This Hungarian notes wait for SPACE key activity. I tried hit space in the any emulator but without any effects. I analyzed its code and found that it reads $FF08 without previous write to it. Standard IRQ kbd sequence places $ff to $fd30 in the its end - this means for all emulators that in $ff08 will be latched $ff. I wanted to test real hardware to prove one my hypothesis. Your results show that another hypothesis required.
