Completed design for the Relay Set D of the WITCH-E project.
this section latches 5-bit patterns from different source such as the tape reader. using a series of AND with OR gates the 5-bit value is decoded to decimal.

oh! this is interesting! they are using "Scraping" cutting printer to cut their own punch cards! this process might be usable for my WITCH-E tape reader!

"Around 60% of differences in GCSE results can be explained by genetic factors, with the same genes responsible for maths, science and the humanities." "You may feel you are just not a maths person, or that you have a special gift for languages, but scientists have shown that the genes influencing numerical skills are the same ones that determine abilities in reading, arts and humanities."

"We found that academic achievement in English, mathematics, science, humanities, second languages and art were all affected by the same genes. People may think that they're good at one subject and bad at another, but in reality most people are strikingly consistent."

So which genes make you good a lot of things and utterly horrible at a select few? Or is that caused by the teacher?

+David Anders It is interesting (and a bit humourous) to be reminded of how people thought of computers. The introduction has many ideas that probably sounded perfectly fine back then but are quaint today e.g. comparing a computer to a human brain.

+Thomas Ruecker - the red dotted line rectangles are ground fills connecting several components. In Eagle you have an option to not view the fills while doing layout and i generally post the images without the fill. in this case, your question revolved around the two vias connect IC56 and IC38. if i were to do the connection on the top layer without vias, that would isolate one side of the fill prevent a connection.

Ah, that makes sense. I was suspecting it would be related to those dotted rectangles.

I love spending time sitting down and using the various vintage computer systems I've collected over the years, but more than that I enjoy learning new bits of history about these systems and how they came to be. While my vintage collection is sizable — 16 systems (excluding consoles and ...

Embedded Linux Developer

I am an embedded systems engineer specializing in the integration of hardware and software at the lowest levels utilizing Open Source tools, bootloaders, and operating systems such as Linux to rapidly produce quality products. Past product developments have included the TCSX-1 thin client for Advantage Business Computer Systems, the M5900 handheld for American Microsystems Ltd., and the PandaBoard for Texas Instruments.

My specialty is complex problem solving to provide rapid solutions to both hardware and software issues. This includes reverse engineering existing legacy projects as well as processing, assimilating and filtering large amounts of datasheets, schematics, software source code, and management specifications.
