Re: VZ200 - VZ300 5.25" floppy format support?

Yeah I think it has all the disk format info you need in the manual except the checksum algorithm (which is only a byte, can either guess it, ignore it, or disassemble the ROMs). The encoding is fully described, as far as I can see. Thanks Rich! I'm glad this old 80's hardware manual made you smile...

Re: Dumping 2-sided C64 disks

thanks for the reply and I see that my question has been asked before - sorry for not spotting it earlier. Out of interest, I just tried dumping both sides of a C64 disk and it appears that my 5.25" drive can go to track -8, however I did not end up with a valid 'c64_s1.d64' image. Here is some of t...

Re: VZ200 - VZ300 5.25" floppy format support?

ok, well after months of rain, floods and cyclones - I've finally had some VZ floppy disks delivered to me and I've archived them using:

DTC.EXE -fFILENAME -i0 -i2

as requested.

So, where do I upload them please?

Re: Dumping 2-sided C64 disks

first up, my apologies if this idea has been theorised before.. but with C64 flippy disks.. we used to turn the physical media over for side 2, couldn't we insert the disk 'upside down' (I know we'd either had to punch a hole in the disk casing (as the cheapskates among us used to do) or modify the ...

list directory for known / support format disks

hopefully I'll describe this adequately enough.. because Kryoflux has a set of known disc formats that you can archive directly to (eg: .D64, .ADF, .IMG etc.) would it be possible to list the directory for either the physical disk in the Kryoflux controlled floppy drive? (my preferred option), or to...

Re: VZ200 - VZ300 5.25" floppy format support?

ok the VZ300 emulator authors have been quite helpful with providing the following information regarding VZ / Laser / Vtech formatted disks, I hope some of it is of use :) (actually, looks like some replication of what's in the technical manual PDF I posted a link to earlier). 1. DOS DIRECTORY STRUC...

Re: VZ200 - VZ300 5.25" floppy format support?

IFW - thanks for the info. I'm sure I have seen a dissassembly of the VZ DOS ROM (z80), I'll see if I can find it again.

Haven't had time to image the disks yet, maybe this weekend.. sorry but it's mega busy for me with work at the moment :(

Re: VZ200 - VZ300 5.25" floppy format support?

thank you for the help, I'll image the few discs I have as soon as possible. I was given the VZ300 with disk drive etc. by my father in law, it belonged to a friend of his who recently passed away, so it'd be nice to preserve the code on the discs as apparently he was very involved with the Australi...
