Thanks for that fascinating post- I'd wondered about what went on in these ground-breaking little boxes, it certainly broke the mould.

I'd also wondered about the tube commonality between it and those portable 'scopes that appeared in its wake and the thread at least implies what I had also supposed- whilst a tiny telly is a superficially appealing concept to us tech-heads, I did wonder how many people would actually spend a fair amount of money on something that produced a not-much-bigger-than-postage-stamp-size monochrome picture for a short time on expensive batteries, and with all the vagaries of portable analogue reception from directional signals on a less-than-optimum aerial arrangement.

This sort of thing is now definitely worth preserving as an illustration of what was necessary in the past, though- nowadays we're all accustomed to taking high-definition, bright, colour, moving images on flatscreen smartphones/media players for granted and for near-trivial money.
