HP41-CX problem with Printer and Digitaldrive and NOV64d - Hiwi - 01-16-2023 03:48 PM Hi all, i have a HP-41cx with IL module and nov64d module. On the loop i have a cassette drive HP84161 an an IL printer HP84162. The nov64d has an active Hepax (tried both 4h and 1d) and CCD-OSX module installed. Others rampages are free. (showing NO Rom as expected) I have some programs on the Hepax ram and HEPDIR shows 2310 or so regs free. If the printer is on HEPDIR shows an ERROR: 'NO H-FILEYSYS'. I have disabled the switch on the IL-module so the printer rom does not swap to rampage 4, but no sucess. I cannot explain this behaviour. If the cassettedrive is the only device on the loop I can access the HEPAX ram as expected. What am i doing wrong? Ralf RE: HP41-CX problem with Printer and Digitaldrive and NOV64d - Diego Diaz - 01-21-2023 09:06 PM Hi Ralf, If my understanding of the symptoms is correct, the HP-IL module is conflicting with the auto-allocation feature of the HEPAX module in your NoV-64d. When first turned ON, HEPAX finds page #6 free, and allocates itself into this address. Once you enabled the printer switch in the HP-IL module, it's *also* allocated into page #6. Using HEPAX 4H will also creates a conflict, since this version requires LIBRARY4 into page #4, and the printer code is allocated into this page when disabled by the switch. Sorry about the bad news, HP-IL and HEPAX issues on a CX are known since long ago and you can find info about it in the HEPAX manual. Using HEPAX 1D on a CX with your configuration may work if you set the printer to enable *before* turning your 41 on. This should force HEPAX code into page #C (if available); but I have not tested this exact configuration and have not the HP-IL module with me to confirm that end. Also, using a CV can help (if you don't need CX functionalities) since HEPAX (again, 1D) will be allocated into page #5 avoiding conflicts with any other module (no TIMER allowed though). Hope you find this information useful. Please keep posting if you try some of the above. Best regards. Diego. RE: HP41-CX problem with Printer and Digitaldrive and NOV64d - Sylvain Cote - 01-22-2023 02:04 PM Just to add on Diego answer, I have done some testing scenario that may help you. HP-41CX fullnut + NoV-64d (default configuration: HEPAX-1D, no other roms) Code: HEXEDIT HP-41CX fullnut + NoV-64d (default configuration) + HP-IL (printer disabled) Code: HEXEDIT HP-41CX fullnut + NoV-64d (default configuration) + HP-IL (printer enabled) Code: HEXEDIT edit 1: typos edit 2: if you want us to be more precise, please give us your exact ClonicConfig configuration so we can reproduce your specific setup. edit 3: Same exact tests with a 41CX halfnut (s/n: 2814S...) gives the same results. RE: HP41-CX problem with Printer and Digitaldrive and NOV64d - Diego Diaz - 01-22-2023 11:46 PM Hi Sylvain, Thanks for taking the time to check these configurations and confirming the behaviour expected on every case. Your input is always welcome. :-) Best wishes. Diego. RE: HP41-CX problem with Printer and Digitaldrive and NOV64d - Hiwi - 01-23-2023 11:41 AM Hi Diego and Sylvain, thank you very much for solving my problem and the configuration examples. It works now and i am happy. Ralf RE: HP41-CX problem with Printer and Digitaldrive and NOV64d - Diego Diaz - 01-25-2023 08:32 PM Hi Ralf, And thanks for the positive feedback. Enjoy your 41s! :-) Diego. |
