I found some stuff while sorting out some old computer stuff.
Way back, when my Amiga was my main computer, i wanted to make my own version. A modular one.
So i started to segmentize the amiga, to put it on several exchangeable cards.
Eurocards are standardized prints 150mm x 100mm, mostly with a DIN41612 connector.
When you make modules you can change/upgrade/test, you can have a very easy interchangeable system using a backplane like this
So i started planning those modules:
- CPU – 68000 but upgradeable to 68030 or alike
- Memory – With expansion
- More IO possibilities
- Keyboard (see more at the bottom of this page)
I had a nice case which could hold a big backplane, custom powersupply. And a front panel containing drives, leds and knobs. (I know i have more info on this somewhere on my fileserver)
A nice example picture i found on danceswithferrets website
I never finished this project.
I used Tech Manuals and print layouts to understand how things where done.
I started to draw the modules like they where placed on the print on semi transparent (chalk)paper, the kind of paper that was used for electronic and mechanic diagrams.
