Does anyone know if a list exists with various models of these Vtech machines, and what hardware is in there?

I come across Vtechs semi-regularly in places like thrift stores & flea markets. And wouldn't mind having a go at some.

The model discussed here seems fairly hacking/modding friendly (discrete Z80, cartridge port etc). But I suspect most Vtechs are dirt-cheap, undocumented ASICs + tiny LCD screens. No fun hacking that (besides ~0 collectors value).
