A small update to my BIOS and Monitor code. Last update was 2.02. This version adds support for JUMP table calls to use Xmodm-CRC Load and Save functions from another program.

An updated Enhanced Basic (CMOS version) was also completed that provides LOAD and SAVE functions using the updated monitor code.

I've uploaded the new code to my Github page. Code size is still very reasonable: BIOS under 1KB (includes 5- 32-byte I/O addresses). Monitor just under 5KB. EhBasic at 9.75KB.

Inside 16k total? I like it!

Yes, it will fit in just under 16KB. However, my default locations in ROM are spread out a bit. With the Monitor and BIOS having 6KB and 2KB allocated in total (including I/O).

I've allocated BIOS space from $F800 - $FDFF and $FEA0 - $FFFF. I/O space is from $FE00 - $FE9F (5- I/O selects that are 32-bytes wide)
- currently, it occupies from:
$F800 - $F9F0
$FEA0 - $FFA8
$FFD0 - $FFFF

I've allocated Monitor space from $E000 - $F7FF
- currently, it occupies from:
$E000 - $F3FB

I've located EhBasic at $B000 and it extends to $D6FF

So one could easily fit everything in less than 16KB of ROM and extend RAM from 32KB to 48KB.
