Hallo Michał, > Beware - INT 10,08 (read character from screen) is not supported on the 8088 card! Strange, are you sure? You said you tried BASIC under DOS 1.25. I haven't run any BASIC under DOS the last 15 years so I'm not quite sure of it behavior anymore. But IIRC it behaves just like BASIC on any 8-bits Commodore (= Microsoft as well). If this BASIC is not using function 8 (indirectly through DOS), how does it keep track of changes? Then what about other programs needing this function? (none comes to my mind right now) IMHO every INT function that is supported by the original IBM BIOS and can be supported, should be supported by the BIOS of the 8088 card as well. Should be doable with the new card with its 64 KB EPROM. A possible solution (for the moment ?) is reserving memory which serves as a copy of the screen. Every movement of the cursor and key input is stored here before being sent to the computer itself. So when an "Enter" is detected, the actual line is read from memory rather then being read form the screen using function 8. But I'm not happy about that. Anyway: I also decided to limit the length of the BASIC lines to 80 chars. Which means no table needed to keep track of longer lines. If time proves we need longer lines, it is something that can be implemented later.
