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. :shock:

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.
