Excellent! 1512 DD with EGA graphics was the first family computer we had. I now have a 2086 with a 30MB RLL hard drive. I also have a 1386 which I'd never heard of until I got one off Ebay a while ago. I was using a XT-IDE card in my 2086, but went back to using the RLL drive as I like the sound of it. When you get a keyboard & can boot it you might be able to use something like SpeedStor to investigate the hard drive further. Looking forward to this project continuing.

I remember at my first job, 3 chaps buying these when they came out. I think I had my Amiga 1000 at the time, and was not much impressed by them, graphics and sound-wise. Of course, you couldn't argue with the range of software. Someone else I knew was a computer novice, and he asked me to help him with his new 1512. I recall making backups of the GEM disks for him, and showing him how a spreadsheet worked.

I've got the original PC1512DD disks somewhere.....

Those WD drives seize up on both the spindle and the head stepper motor. A drop of oil is usually all that's needed to get them running.
