On the Amiga 500, 500+, 600, and 1200, what size screws were used to hold the chassis together? Is it the same size screw for all, different screws per machine, different screws front and rear, or were all the holes designed to work with more than one size screw depending on what the factory happened to have in stock?
There is very little information online about this, so I have scraped around and put this together:
trall measured the external case screws on an A500 case that appear to be original. They are Torx T9, the rear three (3) are 9.0mm long at the shank and 13 threads/inch. The front three (3) are 7.5mm long, and two (2) of those are 13 threads/inch and one (1) is 29 threads/inch.
