;o) Whater ya doin'?! I'm trying to keep this auction low so I can win it!

Actually.. do you know anything about the different revisions? I'm surprised to see a letter as high as G on this unit.

Ya, I was close to winning this nice piece. But the odd thing was, was that I did not realize the amount of scammers on eBAy. Some guy claiming to be the guy who posted this auction, and somehow emailed me and told me that eBay made him take the auction down, and that he would still sell it to me. But anyway i figured out that he wasn't he he said he was. But it shocked me. I didn't expect some punks to be watching a kim-1 or to even know what one is. Perhaps there's a group of predators lurking in the shadows of vintage computer auctions. So be warned.

Yep (on scammers). I get bogus "second chance offers" all the time.

You know, after looking at the KIM-1 circuit, if you really want one how about just building your own? The circuit looks pretty straightforward and I bet you could build a functional prototype in not too long. The schematics available online at:

http://www.zimmers.net/anonftp/pub/cbm/schematics/kim-1/index.html

Personally, I am not interested as I am more of a Z80 & CP/M type but a 6502 would be a great platform to integrate with a video chip like MC6845.

It looks like it would be a fun project. Just a thought. Thanks!

PS, Now this guy knows how to do a homebrew 6502 project! Check this out:

Yes, I was also wondering if there already aren't any KIM-1 replicas?

On the topic of homebrew 6502 projects, I like M02 (http://freenet-homepage.de/dieter.02/m02.htm) by Dieter Mueller, built entirely out of 74LS parts, EPROMs and RAM. Look, no CPU! He also has built a 16-bit computer out of a few 74LS and an impossible amount of transistors.

WOW! I am impressed. Cool!

The 6502 is still available as the 65C02.

Thanks!

carlsson,

Yes there is a replica being made by Vince: http://www.vintage-computer.com/vcforum/showthread.php?t=7209

The direct link is here: http://www.brielcomputers.com/micro-KIM.html

Other than that you can try your luck with some of the books or tutorials out there also on trying to make a replica (although I think Vince pointed out that some of them had incorrect wiring): http://www.6502.org/oldmicro/buildkim/buildkim.htm

Yep, Vince posted about his project the same day or the day after I wrote it!
