Re: RAM Packs Alternatives?
Although the picture is quite blurred It looks like the solder coating has worn down to the copper tracks underneath in places making the edge connection unreliable, I would do as stroebeljc advises and re-coat the edge connector with solder.

Re: RAM Packs Alternatives?
yes, 16K or larger capacity RAM packs for the ZX81 should work fine with a TS1000. Also 2K, 3K and 4K made for ZX80 work fine on a ZX81 or TS1000 I Thought a track had to be cut in these ZX80 RAM packs for them to work rather than plug and play as your post suggests, apologies if I've misunderstood...

Re: 384 rows super HRG
Unless it's usable on a real zeddy I can't see the point other than a proof of concept for emulator use, if it's just a see what's possible exercise for Eighty One then yes I get it but something for real kit would be more useful I would have thought.

Re: RAM Packs Alternatives?
Paul is correct in my opinion. The 80's edge connectors were terrible whereas the modern replacements are far better, one example is of those fitted to Charlie Robson's Zxpands. The white issue 6 I have from him has an edge connector that grips like a vice and like all my other spands suffers no wob...

Re: End of Z80 production?
Mentioned on a few other forums too, luckily I have about a dozen or so in my spares box mainly Zilogs including a few CMOS ones which should be enough to see my time out.
