Here are my SBC-2 Operating System Source Files.
They include:
sbc.asm - The build file that includes all the other files in the proper order
(you would assemble this file with TASS)
reset.asm - reset and IRQ initialization
sbcos.asm - monitor & minassembler
acia.asm - 65c51 init and IO support for monitor
via1.asm - via # 1 init
via2.asm - via # 2 init
basic.asm - Enhanced Basic 2.22 (modified slightly from Lee's distribution)
basldsv.asm - load and save routines for EHBASIC.
upload.asm - XMODEM/CRC & Intel-Hex File Upload support
Compiled using TASS using the following command line:
TASS /c /lsbc.lbl sbc.asm sbc.bin sbcos.lst
The compiler list output file from TASS is called:
sbc25.lst
The label file contains all the labels and their addresses and is called:
sbc.lbl
There is 1 compiled file included:
sbc25.rom - the 32k raw binary object file (only the upper 20k are used)
Good luck!
