4 This release of Basic09 for the Tandy Color Computer 1/2/3 represents
|

|
5 the first community-based release since the discontinuation of the CoCo
|
|
|
6 in the 1980s.

8 What's New
|
|
|
9 ==========
|
|
|
10 Other than 6309 support, there aren't any significant changes to Basic09.
|
|
|
11 RunB for 6309 and 6809 are almost identical, and only differ by one byte,
|
|
|
12 which is due to the register stack differences of the 6309. The Basic09
|
|
|
13 module for each processor differs considerably, however.
|
|
|
14
|
|
|
15 The 6309 verison of Basic09 is optimized for the 6309 processor and should
|
|
|
16 be noticably faster than its 6809 counterpart.
|
|
|
17
|
|
|
18 With additional integration work, the 6309 version of RunB will contain
|
|
|
19 the same 6309 optimizations as Basic09. This will appear in a future release
|
|
|
20 of this package.
|
|
|
21
|
|
|
22 The gfx, syscall and inkey subroutine modules are also included, as well
|
|
|
23 as gfx2, the graphics module for OS-9 Level Two and NitrOS-9.

25 Installation
|
|
|
26 ============
|
|
|
27 1. Change into the directory that holds the diskette:
|
|
495
|
28
|
|
738
|
29 chd /d0
|
|
|
30
|
|
|
31 2. Included in the package are two install scripts: install6809 and
|
|
|
32 install6309. Both scripts will copy modules to the /DD device. Run
|
|
|
33 the script that corresponds to your processor.
|
|
495
|
34
|
|
738
|
35 3. Once the script is complete, all modules should be in the appropriate
|
|
|
36 places on your /DD device.
|
|
|
37
|
|
|
38 4. For OS-9 Level Two systems, you may want to merge runb, gfx2, gfx,
|
|
|
39 syscall and inkey together for better memory usage with packed Basic09
|
|
|
40 programs. To do this, type:
|
|
495
|
41
|
|
738
|
42 chd /dd/cmds
|
|
|
43 merge runb gfx2 gfx syscall inkey>new_runb
|
|
|
44 del runb
|
|
|
45 rename new_runb runb
|
|
|
46 attr runb e pe
|
|
