Thanks David. I've done some experiments with various TVs around the house and web searches to confirm your numbers which as we all knew were correct. So, I...
Hi, I'm ready to build my Membership Card rev 2 now but I'm wondering about how to mount it. Some of the photos I've seen show pretty fancy cutouts on the...
Hi Nick: One way to work the Altoids tin is to fill it with water, then place it in your freezer. When the water has turned to ice, it can act as a support...
I used a Dremel tool with an abrasive cutoff wheel which is why mine has slots instead of holes. I found this increased the tolerances a bit making it, for...
All, For the past several months I've been quietly working to locate the former owner of Quest Electronics partially to determine the copyright status of the...
Great work, Steve! It's nice to have the Quest copyright issue answered once and for all. Thanks for the upload. Dave ... [Non-text portions of this message...
Steve, That's fantastic! You probably have a better collection than I do but if I have anything that can fill in the cracks I'll happily contribute it to the...
Nick, Been trying to post the Manual in the files section under Quest Docs, but the file I have at my finger tips today is too large. I'll squeeze the air out...
... I used the Front Panel board as a template. I taped it to the Altoids box cover, then drilled little holes where the switches, LEDs, and D-connector go....

... Ice expands 4% over the same volume of liquid water, with tremendous force. It can break copper and iron pipes! Of course it shatters glass. So I don't...
Ok, files are fixed and should download without issue and be reasonably sized... Super Elf Manual and Super Elf Expansion manuals are in the files section...
I used a Whitney No. 5 Jr. hole punch on my Altoids tin. In other instances where I have to drill thin sheet metal, I put a piece of wood on both top and...
... It is possible; but it just *barely* fits. The switches have to be right tight against the board, the leads on the back sides of the boards trimmed very...
... I managed to get everything but the switches to a decent height. As it was, I was considering nibbling out a rectangle for the switches and just let them...

Well, I wasn't quite ready to hatch this egg, but Lee's recent Nixie comments inspired me to let crack it open... Since I have a Super Elf with a 44 pin edge...
... Beautiful! You're way ahead of me, Steve! Question: Have you used it? My thought is that the 1802 instruction set is hex-oriented (upper 4 bits is the...
... Definitely. Practically the whole point of the project is showing it off once it's done. ;) ... I was thinking about that as a possibility. The idea I had...
... It's not as bad as one might expect. So far, I've been tinkering with the Octal Nixie tube display on my Elf with binary switch inputs. Since I'm not...
... There are other processors where use of octal does clarify the instruction codes. In the 8080 and 8008 from Intel, there are eight destinations or sources...
Herb, Well put. I remember loading the octal bootstrap routing in to my Varian 620L so that it could read the paper tape into core to run Basic. Binary 16 bit...
... I was still using HP2000s in rocket testing only a decade ago. So far as I know, they're still there--they would have been very hard to get rid of since...
