 Posté le: Lun 01 Jan 2018, 17:31 Sujet du message: TeleBASIC v1.0 v1.2 (Club Apple, 1985) |
 |
|
#989 - Written by Joel Bernard in 1984 and published by Club Apple in 1985. This is a set of telecom (eg videotex) routines for the Applesoft basic.
Joel Bernard is known for his telecommunications programs published by Version Soft.
Note: this software has the MEANEST DOS 3.3 protection routine: it inverts the read and write commands of the RWTS. If you call a read sector, it will write it. It you ask for a write, it will read the sector. So... always protect your disks!
Disk structure
Nearly standard DOS 3.3 16-sec disk
Protection type
Change of markers
- T0-T2: D5AA96 F2AA / D5AAAD F2AA
- T3-T22: D5AA96 F2AA / AAD5AD F2AA
- Sort of desync of data field, see $BF68
- RWTS command change: 01 is 02, 02 is 01 (when you read, you write!) at $BDB5: EOR #$01, init $B7F4 at $B725 where A9 02 8D F4 B7
How to copy
Boot my copy disk
Launch Advanced demuffin 1.4
Press B to boot with Télébasic v1.0 floppy in D1
Write protect your original disk!!!!
Enter monitor
BDB5:49 01 => EA EA
That is MANDATORY or you will lose your original disk!!!!
How to normalize
Boot my copy disk
Launch Disk Fixer
| Code: |
T0/S1/26: 02 -> 01
T0/S1/68: 02 -> 01
T0/S3/35:F2 -> DE
T0/S3/91:F2 -> DE
T0/S7/0:4C C2 BE EA -> 84 48 85 49
T0/S7/B5:49 01 -> EA EA
T1/SE/27: 01 -> 02
T1/SE/3E: 01 -> 02
T1/SE/B2: 01 -> 02
T1/SE/B6: 02 -> 01
T1/SE/E0: 02 -> 01
T1/SE/F8: 02 -> 01
T1/SE/FC: 01 -> 02
T1/SF/31: 02 -> 01
T1/SF/41: 01 -> 02
T1/SF:5B:29 01 0A EA -> C9 02 D0 06

The changes on T1/SE and T1/SF are in the File Manager part of DOS 3.3. I invite readers to buy the following book: Apple II DOS 3.3 guide du programmeur, by Marcel Cottini, published by Sybex.
Why is it important to normalize the disk
Once the markers and data read routines changed, one could stop here. I've decided to go further because of the RWTS. If one has wanted to use the RWTS of Telebasic in its own programs or to copy other disks, they would have been destroyed. For instance, Advanced demuffin uses the read command (01) to read an original disk. With that RWTS, it would have written sectors instead of reading them!!!
The disk image is available at http://www.brutaldeluxe.fr/crack/
Reboot and... enjoy (and write protect your original disks)

The modified data field read routine at $BF68
| Code: |
The $BF68 code.
The timing bits added in the data field!
----------- DISASSEMBLY MODE -----------

The RWTS code at $B7AB, the one that switches between the read and write commands. The DOS 3.3 was modified to read data with a command of 02 (instead of 1) and to write data with a command code of 01 (instead of 2)
