Re: TA ScreenTyper 5.25 in. floppies

Unfortunately, the files I get are not okay. There seems to be something wrong with the order in which the sectors are read. Looks for me as if an obscure skew or interleave has been used. It's a time consuming trial and error now... I even thougt of writing your stream-images back to a disk and fee...

Re: TA ScreenTyper 5.25 in. floppies

Congrats! I also got some files of the disk. But they still look some kind of weird to my eyes and there are a lot of unreadable directory entries with the same name (00ch.wp) on the first disk. I used this diskdefs with cpmtools: # BEGIN screent TA/alphatronic screentyper - DSDD 48 tpi 5.25 diskdef...

Re: TA ScreenTyper 5.25 in. floppies

In the scopy_335.zip file (you googled and downloaded allready I guess) is a subfolder called "VP" with a file called selectdat.xls which is an excel table describing the file formats that scopy can handle (including the SCREENT format). But the rows are not named and therfore its not of much help. ...

Re: TA ScreenTyper 5.25 in. floppies

I'm not sure which format I should use with cpmtools. Have you selected one from the list in the defintions file or did you create your own? I always get the error message: "invalid OS type `2'"

Re: TA ScreenTyper 5.25 in. floppies

Kryflux does in deed decode the streamfiles! DTC is the command line interface. If you prefere the graphical user interface go to file/settings and choose "mfm sector image" but change the track distance to 40 and you will get a proper image. Dont be mislead by the yellow H boxes. That only means th...

The screentyper (as most what TA/alphatronics did that time) is a CP/M machine (afaik)!

Re: TA ScreenTyper 5.25 in. floppies

Supercopy should read and write theese disk on MSDOS PCs (so called SCREENT-Format)! Google for scopy_335.zip to get a copy including a full manual in german language. But be aware that you need a native MSDOS PC to install the special floppy drivers via the CONFIG.SYS file... Supercopy covers about...

Re: 128K/180K PC 5.25" Floppys.

Well, that looks right for me. What did you excpect?

If you only have 40 tracks on one side you can only read 40 tracks and the rest should be grey! The same happens if you have 80 tracks and tracks 81 to 83 are grey...

Re: What is 'L2' on a Panasonic JU-475-5? I've dislodged mine!

Yes, if the coil is disconnected the drive will not work because there will be no 12V power supply on the board.

I would agree that shortening the two legs of the coil with a wire is okay if powered by a separate PSU. Other drives don't have that coil at all...

Re: Problems/advice with ripping Apple ][ 5.25" floppies...

What problem? The initial problem (first posting from joejoetheclown) of this thread wasn't a real problem but a misinterpretation of the GUIs output! If you are using 80 track drives to read 40 track disks, you should read every second track to get a proper result. The GUI does this by design an no...
