Well.. I am one of those that got on the bait an bought an Apple 1.
Its just a reproduction PCB, so quite "cheap" compared to the ones in museums. But it will probably take a long time to get hold of all the components.. that is components with date codes from 1976.
Anyone else here trying to put together or got an early 6502 computer? KIM-1 was the first I believe (1975).. and VIM-1 (or SYM-1) from Synertek (around 1978).

I have an L-Star that is an Apple 1 (and others) compatible computer. It's really nice.
On a different front, I have designed and produced my own 65C02 computer (Potpourri6502). While I don't have video yet, that is my next project.
It's a stepping stone to my more elaborate 8-bit wonder-computer I hope to design.

I don't have one, but I thought I should mention the Jolt, which is probably the first 6502 system not from MOS.

EDIT: oops, that was the "Super Jolt," a later upgrade. Here is the original Jolt:

An interesting note:
the SYM-1 was a later development from the Jolt, by the same guy, Ray Holt. Holt is also arguably the "inventor" of the microprocessor. In 1968 or so he created a microprocessor chipset (not a single chip) for the classified Central Air Data Computer for the US F-14.

Things are starting to get together. I have been able to get sockets and most of the ICs (only missing a few Signetics ICs). The 6502 is dated 0677 and is in plastic packaging. Since the build is a NTI board, that puts it into the correct period (many NTI boards shipped in 1977).
The 6502 from February 1977 (this is an Atari Night Driver arcade board):
I hope it still works. The computer will be tested with some other 6502 before I put in that one.
