Re: OSI + Gotek (youtube video)
Very nice! I have a gotek drive I bought for Amiga but never used yet. Now all I have to do is get my C4P working...

Re: OSI + Gotek (youtube video)
What a breakthrough!
Now, we need a way to convert between the HFE images and the WinOSI disk format (since that's the de-facto standard, and it's very compact).
Once we have that, we've solved the problem of bringing up an OSI disk system without any pre-existing disks, without having to manually construct the disks over the serial port.

Re: OSI + Gotek (youtube video)
This is a great development! For those of us who are tech-challenged and plodding along using legacy hardware and disks only, is there any chance of getting a step-by-step primer for achieving just what you did with your C4P?
Thanks, Tom

Yes I could do that at some point soon.

Re: OSI + Gotek (youtube video)
Here is the process that allowed me to get the Gotek floppy emulator working on my C4P-MF
I had been struggling with my MPI drive for a number of years now, I even got a second MPI drive but that ultimately failed too. These drives are getting very old. My realisation was that I needed to upgrade my drive to a (slightly) more modern 1/2 height drive. Unfortunately the data splitter is built into the MPI drives and a solution need to be found:
1) Purchase a 1/2 height 5.25” 360k drive
2) Order a Klyball D13 Data splitter and build it up
3) Install the D13
4) Using a O-Scope set the timing to 6us on the D13
5) Build (or buy) a cable. ID32 connect to D13 side. Older style CE34 on the disk side.
6) Test setup. Worked!!!! (although some disk written on the MPI drives were a little problematic with loading on the new drive. This was probably due to head alignment differences)
Now for the Gotek part. First thing you will need to do is get a Gotek drive, and flash it for either HxC (10 Euros) or FlashFloppy (free).
http://torlus.com/floppy/forum/viewtopi ... 486#p16455
or
https://github.com/keirf/FlashFloppy/wi ... rogramming
After some discussion with the HxC and FlashFloppy guys, it was decided that a Kryoflux dump of an OSI disk would be needed. Dave offered to purchase a Kruflux, and was able to dump a C4P 5.25” floppy (Tutorial Disk 5) to a kryoflux RAW multi file format.
7) Add another ID32 to the connector I built. This cable will now connect to both the Gotek drive, and the 1/2 height 5.25” 360k drive.
8) Plug the Gotek in. Don't forget that one drive will need to be set as drive 1, and the other as drive 2. This is done with jumpers on the drives. Drive 1 will be the boot drive. I have my Gotek setup as the boot drive 1.
9) You will need to find a way to power the Gotek. I used something like this to power both the 5.25" drive and the Gotek off the original PSU:
https://www.ebay.com/itm/4-Pin-Molex-Ex ... Sw9hlamSXW
10) I was able to take Dave’s RAW multi file Kryoflux dumps and convert them to .hfe format using HxC tools.
11) Rename the resultant .hfe file to DSKA0000.HFE, then load the .hfe file and an appropriate .CFG file onto a Fat16 or Fat32 formatted USB drive. Plug the USB drive into the Gotek.
12) If all goes well, then you should be able to boot from, or access the Gotek drive from the OSI.
13) I was then able to dupe up the DSKA0000.HFE disk image on the USB drive and rename them to DSKA0001.HFE, DSKA0002, DSKA0003.HFE etc. and make disk copies from real disks to the disk images on the Gotek.
DONE
That's all from memory, so hopefully I didn't forget anything.
