ZX-81 / TS 1000 keyboards

My friend and I have come across a large stock of working ZX-81 computers that are missing keyboards. And a stock of others with bad keyboards. 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? I have some samples and a schematic of the matrix so this shouldn't be impossible. We also have a cache of spare parts (Z-80's, ULA's, RAM chips, etc...) for these units. Also, we have a large collection of vintage New Old Stock TTL parts. We are inventorying what we have now, and will post a website with part numbers and quantities available. They've been well stored, and seem to be in great shape. We also found a small stock of Relays, and other parts. Those will be listed on the site as well. It's fun playing with a ZX-81 again. I dug out my TS-1000 and found it didn't work anymore. When we opened it, we found that the Z80 had a bent pin. And over the years it stopped making contact with the contact in the socket due to movement of the parts and corrosion. Once we bent the pin straight and reinserted the Z80, it came up like a champ! And... We also got my Coco III fixed. It came up with a pink screen. We desoldered the 68B09 and put a socket in it's place. I stole a 6809E It now works! Computers in the old days were a lot more fun! Al Phila, PA
