While I'm waiting parts for my 4016, I thought I'd take a look at the 4040 disk drive. It's going to need a bit of work....
I was going to power it up but I think I need to clean up the drives first and get the heads moving freely.
The motherboard is, as always, clean and tidy as it sits on the underside of the lid so it never gets dirt landing on it. And it also looks like it has DOS 2.0 ROMs so that's a start.
