ASCII Keyboard needed

Hi,
Sorry, I posted an incorrect email address in my post.
My correct email address is: michaelvannozzi1@gmail.com .
I purchased the Apple 1 motherboard replica that was on eBay.
I purchased the motherboard that is mounted in a picture frame.
I am currently thinking about building an Apple 1 clone.(this is why I am looking for an ASC-II Keyboard).
I am currently collecting early desk top computers with the idea of opening an Internet Café in downtown Bend, Oregon.
I will have some display cases around the perimeter of the dining room area,
for people to look at early desktop computers,(1975-1980s), early hand held computers, calculators, adding machines, etc.
The café will offer Coffee, Tea, and sandwiches, etc.
Currently I have acquired the Apple 1 motherboard, a Commodore Vic-20, Unused in the original box, (2) RadioShack TRS/80 Model 1.
My wife and I will retire to the Bend, Oregon in about 3 years, so I have that time to acquire the other 20 or so computers for the display.
I will be looking to buy an Apple 2, an IBM 5100, an IBM 5150,an Apple Lisa, an Apple Mackintosh, a Texas Instruments Ti/99-4, a Coleco Adam, a Commodore PET, etc.
So, if anyone knows where I might be able to acquire these early computers at affordable prices, I would appreciate it if you would let me know.
Thank you.
Kind regards,
Michael Vannozzi
