The curator of the Nova Scotia Computer Museum is letting one of his Kenbak-1 systems go at auction. It's on eBay for the next couple of days and had hit $3,900 last night. (Just search on Kenbak. I don't have the auction number handy.)

I'm going to guess that this one will top out near $10K but probably won't surpass the $11.8K that the last one fetched. It's a very nice, clean, functional machine but I'm not sure the CTI logo is as desirable as the "Kenbak-1" one.

Either way, best of luck to the seller and anyone who bids! :)

Yeah, I been watching it too. Not that I can afford it, just curious if it'll go over $10K or not.

Geez, yet *another* machine that I've never heard of before.

Dude, Erik has had it on his front page for over a year now!

Cool, even delivering in person if preferred. Would one take a Kenbak-1 as carry-on luggage or check it in if flying great distances?

Airport security might not believe that it is a computer.

Registers stored in memory. IBM was still doing that in 1965. The IBM 1130 mini computer had 3 index registers, they were memory locations 1,2,3. The 1130 was a 16 bit word machine. All address had to be positive so max memory was 32K words. If the high order bit was on, then the address was an indirect address.

Darn, museum isn't selling the one with the blue toggle switches on the front. Those look better than those black and white jobbers.

Wow. $10,600 to jam68000. Anyone on here?

Barely broke 10K, in the very last second:

Dat's cutting it awful close, even with sniper software.

What did the last one go for? $11,800 or so?

Not bad, really, considering how rare they are.

Actually, I expected it to go a little higher than that. What are there, like 10 of 'em, counting yours?

14 known to exist with the chance of maybe one or two more being in the wild, if that.

Is that 14 complete & working? (Must be a couple of parts donors around somewhere too, I'd imagine).

Depends on what you mean by complete and working. I'm sure most of them out there have one problem or another, but being what they are they're fairly easy to diagnose and repair, if you want.

I don't think anyone would sacrifice one for parts. . .

Erik, doesn't yours have bad switches or something?

Erik, doesn't yours have bad switches or something?

I fixed the switches (a couple had come unglued - much like the owner) but there is a logic error somewhere on the board that I am not about to fix.

I'm sure it's as simple as a failed TTL part or, maybe, an issue with one of the memories but I don't want to mess with a pristine original to get a functional but modified unit.

But that's just me. ;)
