VED.68K was written back to floppy disk and the screen editor was able to run on the actual machine.

The CP/M volume contained 238 files. The screen editor VED.68K and the graphics library XG.O are valuable because they are not included in the bitsavers.org floppy disk images. I have not yet found a way to write these files back to floppy disk, so I will try this over the weekend.

Use cpmtools to retrieve CP/M files. $ mkdir cpm $ cpmcp -f dim68-hd tulin-extracted-1 0:\* cpm The contents of the diskdef file are as follows. ---- diskdef dim68-hd seclen 512 tracks 1331 sectrk 17 blocksize 4096 maxdir 1024 skew 0 boottrk 1 os 2.2 end ---- Extracting MS-DOS...

I do not have the hard disk controller, so I could not try to mount it directly on my Dimension 68000, but I was able to retrieve all the files from the disk image.

I hope you are able to retrieve the MFM image and boot it. I recently found a system with a hard drive on eBay. The seller once accepted my offer, but unfortunately has since rescinded it. It doesn't seem to be bootable, but it is an unusual system...

I got a utility disk for Apple II emulation, which allows file exchange between Apple II and CP/M.

In a case like this video, perhaps the track 0 sensor is broken. As an interim measure, the sensor can be disabled by disconnecting the sensor connector and shorting it out. I have repaired three Laser 128s this way.

Uploaded the sketch to github. Added caps lock function. https://github.com/ushicow/PS2toDim68Keyboard

The floppy disk drive was replaced and ProDOS now boots. I got two SA455-2AA and tried them. I replaced the controller PCB of the SA-455 originally mounted with the PCB of the SA455-2AA. One "59.6.15" (59 means Showa era in Japan, manufactured June 15, 1984) can boot ProDOS and other software...
