I am not the only one who is annoyed by misuse of the apostrophe.
Incomplete manual for a LGP-30 "drum" computer. "Drum" refers to the thing's memory, and if I'm reading it correctly, it can store 4096x30 bits, or 15,360 bytes. (15k.) And check out the power-on instructions:
Turning Power On.Tubes? Tubes? Holy crap!
First, let us consider turning the power on. Turning on the typewriter is simple. Just flip the toggle switch to ON. The typewriter can be turned on even if the computer is not on, but the computer must be plugged in. To turn on the computer;
1. Depress MANUAL INPUT switch. Note that the NORMAL, ONE OPERATION, and MANUAL INPUT switches are interlocked. The MANUAL INPUT switch can only be depressed after the ONE OPERATION switch is depressed.
2. Depress the OPERATE switch.
3. Depress the POWER ON switch.
For fifty seconds the STANDBY light is on to indicate that tubes are at half filament power. For fifty more seconds the STANDBY TO OPERATE light is on indicating that the tubes are at full filament power and that the drum motor is energized. When the operate light comes on, the D.C. voltages are applied and the computer is ready for use.
I like how the manual is written, though. Despite the fact that I'm no longer a tech writer, I still have a professional interest in reading technical writing from half a century ago.
And you've got to love a computer which has an oscilloscope as part of its front panel. It runs at a clock speed of 120 kilohertz, is programmed in raw machine code, and boasts sixteen instructions. Jesus.

Sana: I'll call it "Operation Eyeball-Toothball!
Tsuyoshi: What's the point of naming it?
I love Kodomo no Omocha.
