My Cyclops Projects

First, my sincere thanks to Terry Walker and Harry Garland for their invaluable support for my projects.
I also want to thank Randy Wilson for his efforts in finding and generous loan of his Cyclops setup.

Second, the piece of information that you most want to know is that the image sensor chip is a Mostek MK4008P-9 or an AMI S4008-9 with the lid removed. Lid removal is most easily accomplished with a sharp chisel. With careful handling, the chip will continue to function without its lid. No glass cover is required.

I created an exact reproduction of the Cyclops camera, described in the cover article of the February 1975 issue of Popular Electronics.
A good scan of the original article is here.
A hand bill advertisement for the "SE-1024 image sensing module" (the circuit board described in the article) is here.

I exhibited this camera at the 2016 East Coast Vintage Computer Festival.
Some good photos of my exhibit are on this page.
HACKADAY published an article about it here.

These Cromemco Cyclops ACC board reproductions were produced in KiCad.

Designing The Replica Boards

I started to go crazy with micrometer calipers but after a while I decided it wasn't worth it. Placement of all components, vias and traces are +/- 1mm from the originals. Of course, the image sensor is exactly in the middle of ACC-1 as required. The KiCad projects can be downloaded below if you want to try to do better. These schematics (and boards) match a WORKING ACC example generously provided by Terry Walker. Note that the schematic of ACC-2 does not match any published schematic. Note also that the silkscreen on the board matches the production board, but not the schematic and the actual parts on Terry's board. C5 is 100pF, not 47pF.
