Re: zx spectrum in zx81 case
Interesting choice of travel...
Since there is a CPLD or FPGA sitting there, it would presumably be possible to create a ZX80/81/Spectrum switchable in the same case?

However, it should have either a green or a red solder resist on the bottom

ZX81 Variations
ZX81 Chip Pin-outs
ZX81 Video Transistor Buffer Amp
Standby alert
There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer later in the year.

what's that Smell.... smells like fresh flux and solder fumes...
Re: zx spectrum in zx81 case
Let the upgrades proceed...
1. Switching regulator
2. Internal microfan... not needed modern components
3. Support for ZX81/80 on CPLD as someone mentioned...
4. Spectrum to ZX81 bus convertor is there one? I want to run Z'pand.
Oh wait first... where do I get one?
