 These are a lot from a former Sinclair Repair Center.
 We'd like to get these working 100% again for sale along with the
 remainder of the ZX-81 kits from Zebra Systems.
 BTW... Stewart only has a couple hundred left, and when they're
 gone... that's it!
 Does anyone know of a source for these keyboards, or know of a company
 that could make them up?

 At this late date it would probably be easier to design
 and build an interface so that a common PS/2-type keyboard
 could be used, along with some self-adhesive key-top stickers. 
Seems like overkill - the interface would need more processor power than
the ZX81, most likely.  There *must* be a company that makes membrane
keyboards, and will do a shortish run.  I'd certainly donate a
working-ish keyboard to get some made up...
As an aside, I believe a ZX Spectrum membrane is "close enough" if you
extend one of the sockets so it reaches.
