Hi, In case anyone is interested, I have finally cobbled together a web page that documents the construction of the Popular Electronics Cyclops camera that I exhibited at the 2016 VCF East. It also documents my work to produce a Cromemco S-100 Cyclops that I hope to exhibit at the 2018 VCF

Thanks for the suggestions. I will have to desolder the heatsinks from the board though, and then I can try a good clean up as suggested. I know about those RIFAs, the H7878 had one but it seemed still OK and this one looks to be in good condition, do they show signs of cracking before they go?

Hello, the vertical heat sinks for the TO220 with this design are fairly common, I saw them many times on various boards. However, as they are simply aluminum parts, you can clean them for sure. After removing the screw, you could try simply with an hard brush. If badly corroded, remove the

Beginning of the 70's I was using a pdp-10 at TSL (Time Sharing Limited, UK) over a phone line writing logic simulation software in Fortran. Remember it fondly, especially the number of times I needed to redial in and try to reconnect to my session. Still smell the teletype. Cost about £10 for the
