1861 Replacement

He is not shy about pricing high.

These are just some of the seller's (antiquetech) other items for sale.  Clearly this person specializes in this type of stuff and has several promotional swag/souvenir type items for sale at this time such as other paperweights.

If you like this kind of thing (like the Signetics 2650 micro and industry souvenirs), check out the seller's <see other items>.

*Great!*!*!!  After your wife kills you, she'll put it up on Ebay and the cycle starts all over again!

How about building the VELF?  I think the schematics and firmware is in my folder somewhere....

Thanks Josh,

 

If she does I hope she doesn’t ask for more than what I paid!

 

I will have a look at the VELF and keep the group posted when the chips arrive with my progress.

 As a model railroader, I can agree with that. As a frugal PA Dutchman, I have to somewhat disagree - I have very few pieces I paid full price for as I shop eBay and train shows for bargains. My average is about $40 per locomotive that originally sold for $100, probably my gain to the loss of the wife referenced in the quote. I have stuff I paid a lot more for, I also have stuff I paid a lot less for. It's not so much the trains, it's the price of decent wood to build the layout, and the track, these days.

 With the price these chips are going for, it seems like my buying a Super Elf back in the say was a good investment. It still works, has the original 1802 and an 1861, plus I am pretty sure I have an extra 1802 I got somewhere along the line - not sure if it's good or not. I don't know why I even got an extra. And after all the Questdatas were uploaded, I found out they actually did publish one of my submissions - nothing like finding out nearly 40 years after the fact that I actually was published - forget which year I sent it in, but I would have been 12 or 13 at the time.

Randy, that story is a riot.

For those curious to find your entry, would you happen to know the issue, or the approximate year, or the substance of your program?

Josh can answer that one. But another possibility for your vintage 1802 and 1861 might to build an original ELF from the PE articles. Josh and Chuck Yaykm and I and did one for the VCFMW show a couple years ago, and provided updated parts lists and sources, schematics, and layout. The plans for it are here:

Wrapping is fine.  It's when you find the wire that is the bottom of three wraps needs to move to another pin with three wraps that my blood pressure sky rockets.

Josh,

Are there any KiCad files for the schematic?

Josh can answer that one. But another possibility for your vintage 1802 and 1861 might to build an original ELF from the PE articles. Josh and Chuck Yaykm and I and did one for the VCFMW show a couple years ago, and provided updated parts lists and sources, schematics, and layout. The plans for it are here:

Oh I so need to learn wire wrap

Yep; that's how it was done. :-)

Lest you fear the time and effort it would take, we had visitors to our table at VCFMW *build an Elf from scratch* using wire-wrap. Each visitor added a wire or two. Most had never wire-wrapped before in their lives. Yet by the end of the show, we had darned near finished wiring it!

With regards to the 1861, a later PE article added it to the Elf, with only a few changes to the layout. With wire-wrap, such changes are easy to make.
