Just thought I'd share some photos of my disassembly and repair of my Dynamac, for curiosity's sake, although it may be useful to anyone else tackling one of these beasts.
These screws attach the PSU, they're the only ones on the bottom of the case that don't need to be removed to open the case
This is where the display attaches
They disassembled a Plus to make a Dynamac - they tried to use as much of it as possible - including one of the feet to secure the internal speaker down!
This is the subassembly that sits on top of the logic board - floppy on left, Rodime hard drive on right
This is the keyboard socket normally poking through the front of a Plus - here the cable goes to the daughter board then to the keyboard
Design by Bill Goins - he went on to work at Apple and at Power Computing! So he did two generations of legitimate clone manufacturing!
This sticker on the PSU just amused me
Looks like someone at Dynamac was a Star Trek nerd - if you don't know, google "NCC 1701"
Daughter and motherboard assembly - the Plus's RAM is at the bottom. Internal SCSI cable looping out from under at right.
Logic board sandwich
Here you can see how the main 68000 CPU is wired into the daughterboard
Happy and running again!
I stupidly forgot to take any photos of the inside of the PSU. It is a bit cramped and not fun to work on at all. I had to open it up due to exploded foil capacitors, which weren't as hard to replace as I was worried they would be, but figuring out the correct ones was difficult as it was so hard to read the labelling on them.
I'm now searching for the system software that should make it work in its full intended screen resolution of 640 x 400 - at the moment only running in 512 x 342
If you can help please PM me!
Any more photos wanted? Questions?
