+mizapf Posted April 25, 2018 Share Posted April 25, 2018 Does someone have a HFDC with a Lotharek/GoTek device here? I need a formatted .hfe image because I suspect a minor glitch in the HFDC emulation in MAME; it is producing DDAMs instead of DAMs (F8 instead of FB). Maybe I misinterpreted the semantics of a bit in a HDC command. With a .hfe from a real HFDC I could easily check this. Quote Link to comment Share on other sites More sharing options...
+9640News Posted April 25, 2018 Share Posted April 25, 2018 I've got a setup but I am at work today. Will see what I can do this evening unless someone beats me to it. You need single or double density, or does it matter? Beery Quote Link to comment Share on other sites More sharing options...
+mizapf Posted April 25, 2018 Author Share Posted April 25, 2018 I think it should become obvious in both cases. DSDD is preferred. Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted April 25, 2018 Share Posted April 25, 2018 Fritz442 uploaded a ton of different HFE image formats back in 2015. You can probably get the one you are looking for << HERE >>. Quote Link to comment Share on other sites More sharing options...
+9640News Posted April 25, 2018 Share Posted April 25, 2018 I did not see a specific format with indication it was done specifically with the Myarc HFDC which is what Michael is seeking. Beery Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted April 25, 2018 Share Posted April 25, 2018 Boy, that limits potential pool of people being able to help, 1) The person making it will have to own a rare HFDC and... 2) ... still have a physical disk drive (to make the image)... and 3) have something like an HDX to copy the image over to the PC using something like DSK2PC. Not impossible, as I can think of two or three people, but still... Quote Link to comment Share on other sites More sharing options...
+mizapf Posted April 25, 2018 Author Share Posted April 25, 2018 I'd have in mind you have the Lotharek/GoTek floppy emulator connected to the HFDC, where it creates the HFE file on the memory card, then you just plug that card into a card reader and get the file from it. No? Quote Link to comment Share on other sites More sharing options...

No? I don't know how the HFDC works, but I don't believe you can format a NEW image directly on the Lotharek HxC with the TI-FDC, at least I was never able to do it in my early experimentation with it. The Lotharek is designed to work with pre-existing images. Quote Link to comment Share on other sites More sharing options...
+mizapf Posted April 25, 2018 Author Share Posted April 25, 2018 And re-formatting? Couldn't you use an existing DSDD image, then format it with the HFDC? How should the HxC notice that you are actually formatting the image and not just write a lot of sectors? I don't have a HxC, so I'm relying on your experiences.

Flottmann1 Posted April 25, 2018 Share Posted April 25, 2018 (edited) With DM2K I can format (CTRL - F) an existing Disc Image (Corcomp Controller) on my Lotharek HxC Drive unfortunately my HFDC is defect Edited April 25, 2018 by Flottmann1 Quote Link to comment Share on other sites More sharing options...
+9640News Posted April 25, 2018 Share Posted April 25, 2018 Michael, I just realized my Geneve system has two controller cards present in the system at the moment. A Myarc HFDC and a Myarc FDC. The Myarc FDC is what is connected to the Lotharek device. I'm going to have to do some card pulling and moving cables to get this setup to get you the file you need. It will likely not happen until this weekend. My TI system had just the Myarc HFDC in it, but no Lotharek. For the others inquiring, the Lotharek with the SD card will allow you to reformat an existing image. If you have HyperCopy, you can even set the interlace and skew but this can only be done with the TI FDC, CorComp FDC, and Myarc FDC. The Myarc HFDC is not supported under HyperCopy for formatting.

+arcadeshopper Posted April 26, 2018 Share Posted April 26, 2018 I have the hfdc on my geneve I can move over the lotherek if nobody else does, its in an external drive bay.. Quote Link to comment Share on other sites More sharing options...
+9640News Posted April 26, 2018 Share Posted April 26, 2018 My drives are all internal with hard drive cables barely long enough with the external hard drive sitting on a shelf two inches above the PEBox. I have to unplug all kinds of stuff, so if it is easy for you, go for it. Beery Quote Link to comment Share on other sites More sharing options...
+acadiel Posted April 26, 2018 Share Posted April 26, 2018 Do you need it formatted by the HFDC and by something like MDM V so it uses the Myarc DSDD 320K format? I should be able to take a Corcomp 360K “blank”, stick it into a HFDC GoTek and use MDM V to format it. Just need to find some time, which has been hard lately. Quote Link to comment Share on other sites More sharing options...
+mizapf Posted April 26, 2018 Author Share Posted April 26, 2018 No, just the 360K. The reason is that there is a bit in the write sector and format track command of the HDC9234 that determines whether the sector shall be marked as deleted. The value of the bit differs in the specification between both commands (one requires it to be 0, the other one to be 1). When I formatted a disk in MAME, I saw that all sectors are deleted. However, none of the controllers really cares about this mark, so it has no effect. But it could have, in particular with own read/write functions in copy protections. I need to find out whether the DSR is wrong, or whether it is my HDC9234 emulation. For that reason I need an output of a real chip to compare. 1 Quote Link to comment Share on other sites More sharing options...

MDM5 (V1.25) with what I had on my TI system, offers both 16 sectors per track and 18 sectors per track for formatting. Beery Quote Link to comment Share on other sites More sharing options...
atrax27407 Posted April 26, 2018 Share Posted April 26, 2018 I believe MDM Vn 1.5 is the latestt (current ) version. Quote Link to comment Share on other sites More sharing options...
+acadiel Posted April 26, 2018 Share Posted April 26, 2018 I can format it with DM2K on a GoTek with my HFDC. Might be able to get to it Saturday. The past week has been nuts at my house. Quote Link to comment Share on other sites More sharing options...
Flottmann1 Posted April 26, 2018 Share Posted April 26, 2018 (edited) do not know if it is useful ? have these formatted here with my broken HFDC and DM2K on a Lotharek 997 - 90k 998 - 180 k 999 - 180 k HFDC.rar Edited April 26, 2018 by Flottmann1 1 Quote Link to comment Share on other sites More sharing options...
+mizapf Posted April 26, 2018 Author Share Posted April 26, 2018 have these formatted here with my broken HFDC and DM2K on a Lotharek You're right. It is broken ... in case you still had doubts. There are only 1-bits on the tracks. 2 Quote Link to comment Share on other sites More sharing options...
+mizapf Posted April 26, 2018 Author Share Posted April 26, 2018 Here is a Java-based command line tool that I wrote to analyse HFE files. $ java AnalyseHFE Usage: AnalyseHFE <hfeImage> <track> <head> {"raw" | "cell" | "byte" | "sect" } ["noaddr"] [<outfile>] It runs on Linux, Mac, Windows and needs a current Java RE. If you specify no <outfile>, the output is shown in the console where you are running the program. "noaddr" suppresses position output in the "raw" and "cell" mode.

+mizapf Posted April 27, 2018 Author Share Posted April 27, 2018 Just an update to the tool. I should mention that it can show the contents of non-standard disks like Diskassembler. raw = track bytes from the HFE file cell = FM/MFM cells encoding byte = cells interpreted as bytes, showing address marks sect = show layout of the track, including sector contents. Eventually, I will add this tool to TIImageTool. AnalyseHFE.zip 2 Quote Link to comment Share on other sites More sharing options...

You can format an image on the HxC drive, at least since the Rev B hardware version. Quote Link to comment Share on other sites More sharing options...
+9640News Posted April 29, 2018 Share Posted April 29, 2018 Michael, Not sure what is going on yet, but I configured my Geneve with a Myarc HFDC. I tried formatting. The Lotharek stepped through both sides of all 40 tracks formatting. Then, when it went back to sector 0, the MDOS formatting routine gave me an error. Not sure why yet. Either way, here is the file formatted, but with no correct writes on sector 0. Not sure if this will help you or not.

+9640News Posted April 29, 2018 Share Posted April 29, 2018 I think I just realized the issue. The cfg file was setup for my drive A: with 80 track. If the above file gives you enough information, let me know. If it doesn't, I will pull things back out tomorrow and repeat. Beery Quote Link to comment Share on other sites More sharing options...
