  1. STARTUP.BAT: … POKE 02DB FF 0041 00 … Two parts: 02DB FF key click off 0041 00 SIO noise off If you don’t want a part then just leave it. If you don’t want both then leave the whole statement.
  2. I tried to get Tempest Xtreme but no reply from the developer and on the web page there was a message about health issues. I am fascinated by this game and how close it could get to Tempest 2000 for the Jaguar. Unfortunately, the demo directly loads to D800-DFFF so you cannot load it from a PBI device. Nevertheless I would also appreciate any information on how to get the full version.
  3. See STARTUP.BAT. There is a POKE statement that switches off key click and SIO noise. Just hit reset or remove the POKE statement from STARTUP.BAT. I will remove it in the next release. These are just my preferences but some users got confused about it. Have a nice Sunday Holger
  4. Only the command processor of BW-DOS has the concept of current drive. All CIO calls use 1 if no drive number was provided. The current drive of the command processor in the format Dx:<EOL> can be found at $7A6. So you can get the current drive from $7A7 with PEEK(1959). This only works from version 1.4 of BW-DOS.
  5. The last time I worked on FastAssembler updates. https://github.com/HolgerJanz/FastAssembler Last BW-DOS 1.4 updates including FastAssembler (See https://github.com/HolgerJanz/BW-DOS/commits/main) : - MEM * bug fix for Newell RAMBO 256k and Antonia 4MB Axlon mode * shows now both PORTB and Axlon (yes, there are machines that have both) * can save PORTB values to file for RAMDISK.SYS (file can be edited with HEXEDIT e.g. to remove banks) - RAMDISK.SYS supports PORTB and Axlon - new added High SIO tool HISIOK.SYS by Hias - new executables BWDOS14.EXE and BWDOS14H.EXE (with HISIOK.SYS) for cartridges like AVG, Uno, The!Cart, Side3 etc. - new version of FastAssembler 1.8 16-11-2023 You can check the GitHub repository for updates in the future. Furthermore I converted the XL OS Rev. 2 sources to FastAssembler: https://github.com/HolgerJanz/FastAssemblerAtariXLOS So FastAssembler on an Atari now can assemble itself, the OS, and BW-DOS. Regards Holger
  6. Ok. I cannot remember whether I ever flashed on my 800 or not. I try it if I am back from vacation.
  7. What are the consequences? I use the cart without any modification and it works.
  8. The Web page for that says it doesn't work on the 800 without a solder fix. Is there a no-solder option? I use it without any soldering and it works great. Maybe @JAC! has more insights.
  9. I use The!Cart. You can install more than one versions of SDX. https://www.wudsn.com/index.php/productions-atari800/tools/thecart
  10. Yes, I discovered it while modifying the resident programs - I solved it by simply limiting the search for the installed program to an address higher than the disk buffers, but this is not a great solution, as different DOS could have the disk buffers in other places. Problem with the XOR is that assembling the programs is more difficult, needing an extra step. In BW-DOS you can use start-up-MEMLO: BW-DOS 1.3 BW_SMEMLO = COMTAB+30 (BW-DOS 1.4 = $744). It contains MEMLO at boot time. You just have to search between BW_SMEMLO and MEMLO. Example see sources of RAMDISK.SYS.
  11. Nice to read from you again, Jiri. Welcome back! @Jiří Bernášek Yes, this hobby can be very time consuming and you have to take care of yourself. I do it time boxed and I am listen to my wife The strategy of sector allocation with minimum performance and memory is always a compromise. I am quite satisfied with the current one. It works now for several month and I could not see any issues. I always keep an eye on the VTOC of my working drive. It is a 4MB harddisk partition. I did an update: added executables BWDOS14.EXE and BWDOS14H.EXE (including HISIO driver by Hias), they can be used to start BW-DOS from cartridges like The!Cart, AVG, Uno etc. RAMDISK:SYS now supports ICD Rambo 256k (main banks are ignored now @Ricky Spanish) and Axlon extensions, if your computer is equipped with both PORTB and Axlon then you can install one ramdisk for each add banking file R256D208.BNK for RAMDISK.SYS, it is for the ICD Rambo 256k with main banking, it contains all extra banks plus the main bank RAM under the OS ROM (you could go further and use the main bank $8000-$BFFF if you work with a 16k cartridge like Atari Loge or Microsoft Basic 2) MEM now shows correct values for Newell 256k PORTB and Antonia 4MB Axlon MEM now supports a file option to store the current valid PORTB values in the format for RMADIASK.SYS, this file can be used as a starting point to edit with CUT or HEXEDIT. Added HISO driver by Hias @HiassofT For details see: https://github.com/HolgerJanz/BW-DOS/blob/main/BW-DOS 1.4.pdf https://github.com/HolgerJanz/BW-DOS/blob/main/BW-DOS 1.4.atr Like @dmsc always writes: Have fun!
  12. Still work in progress. In the summertime I do not spend so much time on my Atari.
  13. I have added Fuji. https://github.com/HolgerJanz/BW-DOS/blob/main/1.4/SOURCES/EXT_CMD/SELFTEST.ASM
  14. BW-DOS only supports SpartaDOS file system. Use tool MENU to copy files between SpartaDOS and Atari file system. For more information about tool MENU see documentation page 11 pp. https://github.com/HolgerJanz/BW-DOS/blob/main/BW-DOS 1.4.pdf
  15. Turbo Basic XL 1.5 by Frank O. & dmsc. I am no TB expert but it looks like it reserves a buffer for every active drive to support its DOS commands.
