I think this is the coolest clock ever...used but working DG7 tubes and a transformator cheap, one from Mullard and one from Phillips. Other CRT Cathode Ray Tube types can be used; you can even rip one from an old and maybe dead oscilloscope, then you also get the powersupply and stuff. If you are lucky the deflection amplifiers also work 
Then your own home made Scope Clock is soon up and running, good luck. Link.
Homemade Scope Clock

IIRC, the “SYM” 6502-based single-board computer from the late 1970s [there were also 6502 SBCs called KIM, AIM, etc. --- I think SYM was from Synertek] had the capability to draw/write text on a standard oscilloscope. Don’t think it required any additional hardware beyond what was included on the board, and the relatively tiny software driver routine for that functionality was included in the printed manual. Anyhow, that’s what this project reminded me of
I thought it was going to be some boring old post, but it really compensated for my time. I will post a link to this page on my blog. I am sure my visitors will find that very useful. Thank you!
