Superclock III eprint restoration now available.

Still a few minor typos and such.

This is a demo of a "level II" precyber Linotype age restoration of a magazine story.

Done by starting with Acrobat's Cleartype and overlaying my Gonzo Utilities.

Full text searchibility, full editability, total source code availability, new color, potentially small file sizes (figure dependent), ability to use ordinary scanners and deal with guttering, ordinary standard fonts with zero OCR missed candidates.

With minimal rekeying and redrawing.

We actually worked with NBS on this project. Who at the time were developing an ill fated television vertical interval time base. The networks eventually flushed it in favor of closed captioning and their own diagnostic stuff.

I also wanted to use this for an always accurate WWVB clock, only to discover that WWVB reception relibility was less than negligible. Mesmerizingly awful, even. A power increase did not help much, and their new super modulation seems to have all the development chips currently stuck in the pipe.

I thought that using a ROM for automatic pushbutton timezone conversion was a big deal, but the customers voted with their feet. To this day, few people fully appreciate the significance of a NIST traceable, self resetting, always accurate clock.

Sigh...

Did you do the PCB layouts back then, Don?

Bishop graphics products and mylar, or something else?

Good old tape and dots. Often 4X, sometimes just 2X.

The European equivalent transmissions seem to be more reliable. When we liv ed in the UK we had a single dry cell-powered "Rugby" clock

formatting link

It was a cheap retail device, presumably dependent on a single ASIC

and when we lived in the Netherlands we had the local equivalent that relie d on the German transmitter. We gave one as a wedding present to a friend o f ours whose incipient husband had the irritating habit of keeping all the clocks in the house ten minutes fast ... Nice man - we love him dearly - bu t idiosyncratic.

A couple of decades earlier, the UK electronics magazine "Wireless World" h ad published a series of article on building your own from TTL logic.

Western Europe is pretty compact. I'm about the same distance from Fort Collins as Morocco is from Eindhoven, and Miami would be almost

50% futher (like to Greenland or Syria from .NL).

Of course now we're told that the Crimea is the "heart of Europe" so maybe my maps need to be re-adjusted.

ARRGH! I do remember those days, and not so fondly!

I had a reducing camera in my spare bedroom.

I actually bought a nuarc rocket, and then never used it when we moved.

Mine was a big aluminum box with a surplus lens, mounted on a frame over my light table.

I was out of commission for a while, but in 1996 I completed a laser photoplotter that lays down 1000 x 1000 DPI raster on red-sensitive litho film. So, I can take the Gerber files from my CAD system and make master artwork at 1:1 size. I rarely use it for PC board artwork anymore, but mostly use it to make the artwork for solder paste stencils. I make those out of .003" brass shim stock - like a 2-sided PC board without the glass epoxy in between.
