I modeled this piece by hobby purposes. This is a portable executive version of Commodore 64 computer with integrated 5" CRT screen, released by Commodore in 1984 which I found very innovative and compact looking design ahead of its time.
DX models planned to have two floppy drives as they look on my renders but that version has never released. On SX (single floppy) models, location of the top floppy drive is just used as a empty storage shelf. Some experts on the internet made DX version come to life by attaching second floppy drive to the upper part.
I modeled by looking through the photos of the product (it's expensive and hard to find product). I had 3 different dimensional references.
- Case height, width and length from wikipedia
- 5.25" Floppy place
- 5" CRT screen
By taking those into account, I modeled the rest by distance estimation over photos.
This is the TV ad of the product:
