| == Rel. 4.3 Beta testing: bug reports/fixes ==
| |
|
| |
|
| I should not have sent out the "4.3 beta" a few weeks ago as it was too alpha.
| |
|
| |
| I found a number of bugs that were subtle and affected stability. Now that those are resolved, and the TPDD routines are robust to TPDD problems, I now have a candidate final load. All the features I have considered have been implemented.
| |
|
| |
| R4.3b supports M100/T102 only right now. I will have a T200 R4.3b shortly.
| |
|
| |
| Tested drive targets include: NADSbox, LaddieCon, TPDD-1, TPDD-2
| |
|
| |
|
| |
|
| |
| 1) fixed in 4.3 - timeout of TPDD 1/2 - after loading an image, a command response times out at the end...need to extend the timeout delay.

| == Rel. 4.2 Beta testing: bug reports/fixes ==
| |
|
| |
| 1) DONE R4.3 - found error in code - Year bug - the year data is not correctly preserved by REX when RAM images are saved and loaded. Solution - implement a mechanism that maintains the year data properly.
| |
|
| |
| 2) directory bug with entry for block 31 - it appears that the name entry for block 31 is not displayed correctly, investigation continuing.
| |
|
| |
| 3) DONE R4.3 - sound is disabled - sounds - currently REX uses audible clicks to indicate progress, which can be annoying. Solution - disable audio, replace with some other mechanism.
| |
|
| |
| 4) DONE R4.3 - directories are now sorted in descending order of date/time - directory order - current directory entries are displayed in order of block number, which is problematic since this causes reordering whenever REX garbage collection forces an image to be moved from one block to another.
| |
|
| |
| 5) DONE R4.3 - Overall stability - Identified and fixed two subtle bugs relating to interrupt handling and bank switching.
| |
|
| |
| 6) DONE R4.3 - Robustness for TPDD routines - major rewrite of the TPDD routines in 4.3.
| |
|
| |
| 7) DONE R4.3 - included choice for refresh or revert - Restore from current ram image - there is no easy way to restore from the current backup image. Solution TBD. work around is to copy the backup image to a new block, and then install that image.
| |
|
| |
| 8) DONE R4.3 - non-blank block recovery - it is possible that REX attempts to copy an image to a non blank block. This situation is indicitive of a problem with the system since this should never happen. If it does occur, the system gets in a deadlock condition. Solution - make sure REX has no bugs in this functionality first, but an option to "name" or "delete" the offending block would be a nice safety system.
| |
|
| |
| 9) DONE R4.3 - enter function displayed on line 2 - state function of <enter> for cursor item on screen somewhere - don't leave it to memory only
| |
|
| |
| 10) DONE R4.3 - <TAB> is included in top line now - indicate <tab> is used to toggle groups.
| |
|
| |
| 11) DONE R4.3 - order is now RAM ROM OS (SYS) (SYS is a superuser feature) - change group display order to avoid tabbing past OS type.
