We are currently listing a range of Timex/Sinclair and ZX81 items on ebay brought over from America.
Amongst them will be 8K non-volatile memory interface, a TS1500 computer and even the TS1000 schematic!
We also have several Tree Forth EPROMs (there are some marked TS1000 and some ZX81, so presumably there were two versions). We even have the instructions on how to convert the ZX81's ROM to accept an EPROM as well as what looks to be a home made adaptor to do this (although the EPROM socket has broken off). It is labelled PC89-C on the circuit board - will upload a photo when I can in case someone can identify it!
Keep your eye on our listings for items of interest:
