1 **** OS-9 Level One VR 02.01.00 'Phoenix' Release Notes ****
|
|
|
2
|
|
|
3 This release of OS-9 Level One for the Tandy Color Computer and
|
|
|
4 Dragon computers represents the first community-based release
|
|
|
5 since the discontinuation of both the CoCo and Dragon in the 1980s.
|
|
|
6 Its codename is an obvious parallel: Phoenix.
|
|
|
7
|
|
|
8 There were several reasons for releasing a new version of OS-9
|
|
|
9 Level One:
|
|
|
10
|
|
|
11 o It was long overdue (16 years)
|
|
|
12
|
|
|
13 o Year 2000 fixes were needed
|
|
|
14
|
|
|
15 o Bringing both CoCo and Dragon OS-9 to the same code base
|
|
|
16 was desirable
|
|
|
17
|
|
|
18 o This release served to test our methods for assembly and
|
|
|
19 packaging, which will come in handy as we continue to
|
|
|
20 work on future possible releases of this and other versions
|
|
|
21 of OS-9
|
|
|
22
|
|
|
23 One goal of this release was to consolidate commands and modules from
|
|
|
24 both the CoCo and Dragon versions of OS-9 into a single distribution
|
|
|
25 that would support both systems. The last CoCo version of OS-9
|
|
|
26 Level One was version 02.00.00, released in mid-1986. The last Dragon
|
|
|
27 version of OS-9 Level One was version 01.02.00, released ????.
|
|
|
28 The CoCo version of OS-9, being newer, was the basis for this upgrade,
|
|
|
29 and the Dragon distribution disk reflects the newer OS-9 modules from
|
|
|
30 the CoCo version.
|
|
|
31
|
|
|
32 This goal was accomplished in tandem with another goal: bringing some
|
|
|
33 commonality to commands between OS-9 Level One and OS-9 Level Two. The
|
|
|
34 CoCo 3 version of OS-9 Level Two was released in February 1987, about
|
|
|
35 one year after CoCo OS-9 Level One Version 2. While some commands
|
|
|
36 are Level Two specific, most commands can interoperate in both environments,
|
|
|
37 and we felt it would be of benefit to "upgrade" Level One to some of these
|
|
|
38 commands. We even went as far as to back-port certain commands like
|
|
|
39 os9gen and cobbler from Level Two, because they offered increased
|
|
|
40 functionality. Level Two-specific code was conditionalized out and
|
|
|
41 Level One code was introduced. The obvious benefit for us is that
|
|
|
42 we can now build a Level One and Level Two command from the same
|
|
|
43 source file.
