Fixes and improvements to KIM-1 i/o routines. Tested on real KIM-1 hardware. read.s: - Remove commented out line. - Remove unused check for bell character. - Remove echo of newline (hardware always echoes entered characters). - This fixes gets() and fgets() so they return when CR is entered. write.s: - Fix check for adding return after linefeed (failed to work because OUTCHR changes A) - Remove unused check for bell character. kim1.inc: - Add symbol for monitor entry crt0.s: - Jump to KIM-1 monitor by address rather than using BRK (which relies on vector being set in RAM) 2023-03-27 21:56:25 +00:00			`START := $1C4F ; Enter KIM-1 monitor`
Add KIM-1 functions to write to the 7-segment LED display and get keypresses from the keypad. Includes sample program illustrating how to use them. Tested on real KIM-1 hardware. 2023-03-29 22:40:10 +00:00			`SCANDS := $1F1F ; Scan 7-segment display`
