240 OS-9 V03.01.00:
|
|
|
241
|
|
|
242 - New common version among all releases of OS-9 for the CoCo
|
|
|
243 - Many commands have been updated and optimized:
|
|
|
244 o For size reasons, command help information is no longer embedded in the
|
|
|
245 utilites, but is instead available through the helpmsg file in /DD/SYS
|
|
|
246 o date, dir, mdir, procs and verify now require a dash (-) before options

|
|
|
248 good sectors on large sector devices

|
|
251 CMDS directory
|
|
|
252 o cmp, error, help and touch have been rewritten in assembly for size
|
|

|
|
|
257 vdgint.io module contains both CoCo 1/2 AND CoCo 3 graphics code.

|
258 The vdgint_small.io module only contains CoCo 3 graphics code.
|
|
|
259 - CC3Go has been moved back into the root directory from the CMDS directory.
|
|
|
260 This keeps ROM-based users and those who want cc3go in their bootfile from
|
|
|
261 having to change the init module, which referenced CMDS/cc3go.
|
|
|
262 - CC3Go once again references /H0 and /H0/CMDS as paths that it tries to
|
|
|
263 chd/chx to upon startup. This allows for those with floppy boots who
|
|
|
264 want to point /DD at their floppy to continue to do so. Also, if the
|
|
|
265 forking of 'shell startup' fails due to lack of a shell file, then
|
|
|
266 CC3Go will now try to fork AutoEx instead of jumping to the crash routine.
|
|
|
267 - Several bugs that crept into IOMan during the last release have been fixed.
|
|
|

|
279
|
|
|
280 Level 2 Only:
|
|
|
281 - SCF, Rammer and PipeMan are now made from the NitrOS-9 version source base,
|
|

282 bringing in new improvements and features from that platform.
|
|
|
283 - Clock and Clock2 are now unifed once again and are built from the same source
|
|
|
284 base as the clocks from NitrOS-9.
|
|
|
285 - The printer driver is now for the CoCo 3 serial port. In the previous
|
|
|
286 release, it was mistakenly made for the Disto parallel port.

287 - Window descriptors now have proper initialization count.
|
|
|
288 - The debug program is now part of the CMDS package.
|
