Why limit to the surface? A giant submarine that is hard to detect is more plausable ;)

And yes I do understand your concern

I have had rhubarb in my garden for 30+ years and it died on me last year. I gave a part of it a nighbor, so hopehully I can get a piece back and restart :)

When I started university and got a HP48SX I realised I could do the same thing with the calculator in 4-bit Star machine language. The SX could only generate 32kHz carrier frequency thoug, but the GX could do 38kHz needed. Since it had IR in and out, I could replace Oric-1 + oscilliscope with GX

Found this tape now:

Damn, you scratched an itch I have had a long time :) I have now found the photo copies of the oscilloscope plans. Need to dust off more stuff slowly and see if I can restart the Oric-1. Hopefully I can find the oscilloscope also. Find tapes, tapedeck and digitize the programs and so on

Yes, I still have it. But haven't tried to boot it for many years. I had built a sampling oscilloscope from a kit from an electronics magazine. It connected to the parallell port on the Oric-1. I used them to decode IR-remote controls :)

Yay, an Oric-1 in the wild. This was also my first computer :)

CGN has another problem. Many 1000nth of customers are sharing a few IPs, which leads to reset of active TCP connections if they run too long
