Portable 100/200/600 March 1986

The "Inside the Model 100" article illustrated on the cover of this issue was less general than you might think from the picture: excerpted from a book, it specifically described how the 80C85 CPU "communicated with the rest of the world" through input/output ports. There was an article that involved opening up the computer, though: the purpose of that was to modify the hardware so that nickel-cadmium batteries would recharge when the power adapter was also plugged in. (My family made that modification to our Model 100. While I did dismantle it myself not that long ago to extract the circuit board and mail it off for capacitor replacement, I have to admit that since switching to nickel-metal hydride batteries, I've been swapping in batteries recharged in a modern device instead of seeing what happens when the modification passes current through them...)

Today's vintage tool, a Yankee screwdriver (aka push-pull ratcheting screwdriver) that I got at a yardsale, and it was apparently had belonged to the guy's father. Nicely worn and was definitely taken good care of; no bits included but I have plenty of those. It works perfectly, but I applied a dab of WD40 to improve the motion.

Here, have a better look at the grooving on the shaft that allows it to drive in either direction just by pushing it.
