Intel 80287 Math Coprocessor upgrade!
My Commodore PC40-III has been successfully upgraded with the 287. I don’t know what I’ll need it for, but I wanted to add one.
I’m rearranging my bench equipment layout again to try and find a suitable new layout.
Commodore 1352 Mouse for their PC compatible family.
This is not a serial mouse, and thus it requires the use of a specialized mouse port on the back of the PC-III series. The utilities disk was never unsealed, so I get to do that too.
New layout, same problems: PC40-III doesn’t take to installations onto IDE drives that aren’t in its list.
The Commodore PC40-III finally has a keyboard to match!
There is a chorus of 5¼“ floppies singing away in my room.
Commodore PC40-III
Commodore made IBM compatible machines, believe it or not. This is a later 286-based machine with an IDE hard drive, both 5¼ and 3½ floppy drives, embedded VGA, and 1MB of base RAM in a small form factor. This one has a bad hard drive, but that can be fixed.
