Editing Building SuperBASIC itself

= '''Building SuperBASIC from Scratch''' =
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.

* 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

The output of make:

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'''`.
