Re: best cheap/free scores 1.1

intel are the worst,

Re: 569HC1220A TV Power Supply, All Voltages Except 32V

Re: Help with dead Commodore 1802

it's really strange that you see a resistance but no life - be interesting to do an autopsy and cut the metal cap open!

Re: question about Polymodding

looks interesting.

Re: Win7 Chrome Support May End July 2021

this is all bullshit.
chrome and firefox and webkit are all open-source multi-platform.
