Sorry to spam the list, but I find myself in need of some holiday cash (or
positive PayPal balance, anyway) so I am offering a REPLICA Cromemco Cyclops
Camera for sale. This is ONLY THE CAMERA. You will need to have your own
Cyclops interface board set or build an XYZ scope interface as in the
manual:
https://www.autometer.de/unix4fun/z80pack/ftp/cromemco/Cromemco%2088%20ACC%2
0Manual.pdf
This will be the camera I demonstrated at 2018 VCF East. All three circuit
boards are clearly labeled REPLICA in the copper layer. Details of the
construction and other photographs are on my web page:
http://wsudbrink.dyndns.org:8080/cyclops/index.html#Cromemco
I would much rather sell it here to someone who clearly understands what
they are getting, rather than dealing with ebay. I will also include a pair
of REPLICA side panels (made from measurements of an original) that I had
made last year. I would be happy to zoom with the buyer and demonstrate the
camera in operation.
Email me directly if interested.
Thanks,
Bill S.

Was the image sensor a CCD/PD imager or clever use of a memory chip with a
window?

The image sensor is a MOSTEK MK4008P-9 or an AMI S4008-9. Cromemco used both. They
removed the lid and added a glass cover, but the cover is not necessary. I have operated
several cameras with no cover. If you scroll up to the top of the page, you will see
pictures of the chips. The memory cells in the chips are three transistor design,
allowing non-destructive reads. The device repeatedly reads the cell array, watching as
they fade out due to charge leakage caused by light hitting the cell. Interestingly, the
light sensitive component in the cell is not the capacitor, but rather the transistor
linked to ground. The transistor is sensitive to visible light but is even more sensitive
to infrared (just below visible).
