| If you are using Git bash for a command-line (on MS Windows), you need to tell bash that you're not a real Linux machine:
| |
| export OS=cygwin
| |
| I had to add the make command by following the instructions here: https://gist.github.com/evanwill/0207876c3243bbb6863e65ec5dc3f058#make. From ezwinports, use the '''make without guile''' zip file.

| | See the repository's README: https://github.com/wildbitscomputing/superbasic |
| | |
| * Install python-is-python3 on your Debian or Ubuntu machine
| |
| * Install `64tass`. The version available in the Ubuntu repos compiles the source without errors.
| |
| * Execute `git clone https://github.com/FoenixRetro/f256-superbasic.git`
| |
| * Execute `git clone https://github.com/WartyMN/Foenix-F256JR-bootscreens.git`
| |
| * Change into the directory `f256-superbasic/source`
| |
| * Execute `make`
| |
| * If this succeeds there will be an updated file called `basic.rom` in the directory `f256-superbasic/source/build`
| |
| * Change into the directory `f256-superbasic/source/build`
| |
| * Execute the command `python splitrom.py`
| |
| * If this succeeds there will be 4 updated files called `sb01.bin`, `sb02.bin`, `sb03.bin` and `sb04.bin` which can be flashed to the F256 Jr./K

| I modified the 00start.asm file on line #30 to change the F256Header from "basic" to "sbasic", this way it shows up in the system commands as a separate command.
| |
| | |
| F256Header:
| |
| .text $f2,$56 ; Signature
| |
| .byte 4 ; 4 blocks
| |
| .byte 4 ; mount at $8000
| |
| .word Boot ; Start here
| |
| .byte 1 ; version
| |
| .byte 0 ; reserved
| |
| .byte 0 ; reserved
| |
| .byte 0 ; reserved
| |
| .text "sbasic",0 ; name of program.
| |
| .text 0 ; arguments
| |
| .text "The SuperBASIC environment.",0 ; description
| |
| After splitting the ==basic.rom== into bins, I then flashed with this CSV:
| |
| 08,sb01.bin
| |
| 09,sb02.bin
| |
| 0a,sb03.bin
| |
| 0b,sb04.bin
| |
| After reboot, type `/sbasic`.
| |
| | |
| Type the following in the F256K in 'sbasic'
| |
| print ?(8+4)
| |
| This command is short for print peek(12).
| |
| | |
| Result should be `'''72'''`.
