content: Analog delay lines can also be found in CRT color televisions for timing with the Chroma.Sorry, I don't care for that bench setup . it just dosn't look right to me. Other's here may disagree with me on this one.

content: Do what I did ... use a piece of double sided PCB. Thinner is easier to use, but 1.6mm can work.

content: In AA chargers even 0.8mm is often too thick. A very thin solution is to use a piece of Kapton tape with copper tape on both sides, it is possible to solder wires to this.

content: From that Byte magazine. Look at the über cool Compucolor 8 tracks cartridge "floppy tape memory", it's got 1 MB!. The Compucolors' screens/graphics were simply gorgeous. Sadly, four or five years later, they were out of bussiness. The TRS-80 is nowhere to be seen, because it didn't exist yet. The Commodore PET 2001 came the next month.

content: The Apple II was new then. Note $600 16k RAM. Apple's been expensive since day one. There's another ad later of 16k RAM for $485, but that's with decoding/glue circuitry and mounted in an S100 expansion board, it's $115 less than Apple's bare chips.

content: I'm wondering whether Dave would bother to do a (2 minute?) teardown of my self-made lab psu if I send it to him (which has been inspired by his until now released µSupply schematics) or whether he'd just be disgusted by "yet another self-made lab PSU" and just won't stop ranting about it :-D

content: @11:50, that's the list of warranty repair shops of the thing in the USSR. With city, address and phone number. Back in the days you didn't even think about sending it somewhere with the mail or such. :-) You get an idea how large the USSR was.
