Just wanted to let you know that JiffyDOS support for 1541-III is in beta phase. I've been working on this for a few weeks now with the help of Jan Derogee, Unseen and 1570. Game loading works now but it still needs more testing, and some debugging in card root directory loading (D64 directories show fine). It loads a 170 block game in a few seconds!
I'll post a link in a few days when I've tested it a bit more.

The beta release can now be downloaded from: jderogee.tripod.com/jdbeta.htmCompability with various games needs to be tested, and we can really use your input! Enjoy  |

OK I have this installed into both my 1541-III-DTV V2 boards. SO far the loading feature and sub directory access is perfect on my Hummer. I dont know of a patch for JiffyDOS for the Hummer so I cant test it with that.
I am having a problem sending commands or reading the error channel. Any attempt to read the error channel hangs the system. It seems like the system is waiting for the drive to send the final close message when I watch on the terminal of my PC with TinyBOOT via serial. The previous firmware did work (08-02-27) with commands so it would seem to be something new.
Let me know if there is anything I can do to help, I am more than happy to test any firmware etc.

I just put my DTV2 in a case with a 1541-III-DTV and I tried the patched 6.01 (?) JDOS kernal for DTV and I cannot seem to be able to load anything from the SD card with JDOS softkernal installed.
Can you let me know which verson of the firmware you use on your 1541-3 and which softkernal you use on the DTV for JDOS ? (is it plain original JDOS kernal or patchet somehow ?
PS! Mine just hangs forever on "LOADING" when I try to load a file on the SD card or inside a D64 file when i use the patched jdos softkernal

The timing-patched Jiffy softkernal doesn't fully work on the DTV + 1541-III as of yet. I'll try to get it working too. |

sure:
60000 open15,8,15:input#15,en,em$,et,es:print en,em$,et,es:close15
or:
save"filename",8,1
I am also getting the results Espen Skog is getting when using the JiffyDOS 6.01 softkernal, DTV displays 'searching for filename' and never responds.
Let me know if you need any testing of new firmware I'll be happy to flash my unit and have a go.

yes, I agree. I can't wait to test a new fw. It will make the dtv 100% über-cool  |

yes, I agree. I can't wait to test a new fw. It will make the dtv 100% über-cool Here's a new intermediate beta firmware release which supports JiffyDOS also on the C64-DTV! I'll look into the other problems next. [technical] This was an interesting problem to solve. A bit of tweaking on the timing was needed, but the most difficult problem was the end-of-file marker which was not recognized by the DTV... Strangely I had left the clock signal up from the PIC processor and DTV could not pull it down to acknowledge. C64 had no problems pulling it down The IEC-signaling should rely on bus pullups, and just pull down the needed signals. Oh well... [/technical] Anyway, here's the link to the hex file: www.netsonic.fi/~kelpf25b/jdbeta3.hex |

Hi.
I installed the newest offical 1541-III FW in my 1541-III-DTV and with this connected to the DTV I get loading errors when using the dtv-patched jdos-softkernal which you mailed me. Is this loading-error gone if I upgrade with the FW you refer to above ? If so -- I am very happy :-)
I am curious: Do you know if the patched JDOS softkernal is really needed, or if a stock JDOS kernal works just as well ?

Be prepared to be happy Espen This new firmware works at least with the fixed Jiffy soft kernel on DTV and original Jiffy on C64. I've spent the whole day debugging it... |

Ok, I have this d/l on my dirve and am off to flash it. Will see how it goes and am darned excited!
P.s. Espen, yes the DTV patched jiffy softkernal is outstanding and gives incredible performance with a real 1541C with JD 6.01 rom installed. I was shocked to see my DTV working so fast with loads since the ntsc machines have such limited fast load options. I was unable to get the original unpatched Jiffy Rom to function with NTSC Hummer. It really shines when loading 64k raw image files, only takes a few seconds, which is outstanding for the Hummer.

Well it's closer to working with the jiffy dos as now it gives a response from the @ command but it just keeps streaming error messages off the screen until run stop restore.
SO this seems a bit closer since before when I issued the @ command with the jiffy dos kernal it just locked up totally until reset. Now it is getting response but no end. Am I having the same eof problem with my hummer since the timing is a little dif?

If the new firmware doesn't run on your Hummer then maybe it's NTSC-PAL timing related? I can try to compile some variants with slightly offset timing to find out which works for you.
I'm waiting also for Espen's test results whether it runs on his PAL DTV now. I don't know if there are issues with different DTV versions too...

Hello, Jussi: This is great news. I wish I would have the possibility to flash it and thry it right away. Unfortunately, this whole week I will be in Oslo at the main office and I won't be back to my own office until next monday :-\ But be sure, I will reflash it right away when I get back Expertsetup: I think I will bring out my ye-olde-eeprom burner for the c64 and make myself a jdos romset for the 1541 I have, as it would be cool to have access to my old floppies aswell. I might even make a jdos set for the 1581 I have (which I have never tried as I dont have a psu for it -- have to make one). I think I will make a new DTV box next time which resides inside a small keyboard so it is easy to bring on trips Would make a nice box to connect to the hotel tv. :-) Regs, Espen -- back in 7 days |

Jsaily, I think it may be the dif system speed that is causing me some trouble. I'll be happy to test some offsets, I love any excuse to use my dtv & cbm gear.
Directory listings with cbm dos5.1 are working with the new firmware as is the binary load command % as well as the / command for loading to $801. The @ command to read the error channel with dos5.1 is not quite working, shows the first char then hangs. I am also unable to run the basic program to read the error channel, system hangs as before.
Large files load fine without any problems for me, and sub directory access is working just fine.
Error messages are working in DTVMON from flash which is interesting as the f1 directory function in DTVMON does not work. TLRs FLash program will read the directory and load files but it shows the files as longer by 191 bytes. FOr instance when I load the kernal image for jiffy dos into dtvflash it shows the length as $20bf which is indeed 191 bytes off.
Espen, yeah I think jiffy in the 1581 is a nice way to go since I can R/W with my pc for it.
