Need a Cheap Meter?
Once in a while something comes along that is so cheap it’s almost free, and the Tekpower Handy Man’s Tool
DT830B pretty much qualifies. Aimed at hobby and DIY users,
the DMM provides a 3. 5 digit LCD display with a maximum
reading of 1999, built-in diode test, HEF measurement, and
overload protection. Plus, it’s only $5. Yep, not a typo.
You may as well buy a dozen just so you’ll never have to
root around for one again. It’s available at www.tekpower.us.

$800 and bailed. We’re talking about
Steve Jobs, Steve Wozniak, and Ronald
Wayne. The result was the Apple I
computer, introduced in April of 1976.
(Had Ron kept his Apple stock until 2015,
it would have been worth about $60
Yes, it’s been 40 years. The Apple I —
an estimated 200 of which were built —
was priced at $666.66, not because of
any devilish influence but because
Wozniak thought $777.77 was too much.
For the price, you got a machine that was
powered by a MOS Technology 6502
processor skipping along at 1.023 MHz. It
came with 4 KB of RAM (upgradable to
65 KB), a monochrome monitor capable of displaying 40 x 24 characters of text, and built-in
For storage, there was an interface for a cassette recorder. Keyboard not included. If you are
one of the estimated 34 people who still have a functioning Apple I, be aware that one sold last
year at auction for $200,000. NV
