Wow!!! Cool emulator....

Ah, I think I figured out the image part.

Kenbak1_base.jpg has the background of the machine, and this is the part that could have the extruded handles added, but the existing jpg doesn't have...

Wow!!! Cool emulator....

I'm amazed. After trying the very clever and fun 8088 assembly language emulator, I too had thought it would be cool to have a Java web-based emulator with great graphics, which would be machine...

GR104C Manual? You gotta be kidding...

Okay, now all of us vintage electronics nuts are looking pretty sane. You're actually trying to build a GR104C Healthkit Television? I can't even imagine why someone would do that.

But motives...

Yes, I'm always surprised when a DOS-like program works in the command window of a late product like Vista, but yours does. It looks nice, nice smooth display, quite usable for a text only...

Very cool....

Hey!

Great little emulator! Well done!

I like the memory dump in Octal. Very nice.

I was even more pleasantly surprised that the "4" below the number 2 light is offset to the left. ...

Do binary images exist for any programs? I've seen a few original Altair tapes go for auction, but no web site I've seen has the actual binary images. If I could see the data, I have a whole ton of...

Very interesting. I just ordered one too.

I've been thinking of buying an "itouch" to surf the internet (my whole city is going wireless over the next 12 months) the real keyboard (or "kinda...

Wow, I wondered who bought that kit!!! I thought it was that deep-pocket collector in Florida who's assembling a museum.

Yes, many would consider the kit ruined by assembly. On the other-hand,...

Here's a picture of the eBay $9 power supply (plus around $7 for shipping) in the approximate place (above the original.)

It's bigger than yours, but smaller than the original version. I think...

more comments (ttl, etc.)

I'll attach a picture of the inside, but not much to show. This looks just like your machine. I tried to neaten up the wiring by twisting the wires a bit, but it didn't do much. Maybe a nice braid...

Oh, I talked too soon (Tie inputs high through resistors)

I guess I talked too soon, and found the answer to why John Blankenbaker tied the inputs to his TTL chips through a resistor to the +5 volt supply. I appreciate that nobody has yet slammed me. I...

No, not me. My little girl! She's actually less interested in vintage computers than you'd think by the photo.

Another Finished Kenbak-1, how many are functioning now?

Hello:

That modification on Eric Klein's machine is interesting because it is the first (and only?) modification known on a Kenbak-1. Common sense suggests that this should be an input or output, the only...

IC-99 Mystery (modification)

I see talk about IC-99 (the un-used chip) getting hot. There is a bit of a mystery regarding this, but I really think the original machines *DID NOT* have a chip in this place.
