Re: [N8VEM-S100:6880] Re: Altair Cyclops Info Wanted

The MK4006 was Mostek's version of a 1Kx1 dram, but the construction style looks very much like the picture of the Cyclops sensor in Wikipedia.

I started reading Popular Electronics around 1974, although was a few years before I cut enough lawns to purchase my first "real" computer (An OSI C2-4P).

Nice find.  What's the size of the MK4006? Does it match the resolution of the camera?

Wow, you remember when that came out?  I'm afraid I'm just a bit younger.

John -

I'm suspicious that the DRAM used as a sensor may be the Mostek MK4006.  The pictures of the sensor have the same construction and the pinout looks correct.

Data is on page 96 here:  http://bitsavers.informatik.uni-stuttgart.de/pdf/mostek/_dataBooks/1979_Mostek_Memory_Data_Book_and_Designers_Guide.pdf

I remember being fascinated reading that article when it first came out!

I found the assembly manual and schematics for the camera and controller in the hartetechnologies collection. The controller manual seems to be missing the schematic for the 2nd board of the controller. There is still no description of the imaging chip, except to list a Cromemco part number. Making (slow) progress! There are still some Cromemco people around and I'll try to find and contact them.
