1976 General Electric AM/FM portable radio
A neat little radio with a blown internal speaker, but it sounds great with an external speaker or headphones. Reception is very good and the extra large tuning dial is a joy to use. The last part of the video is a direct hookup from the GE's earphone output to the camcorder's microphone input.
Oddware: IBM M-ACPA microchannel PS/2 sound card
Your options for adding a sound card to an IBM PS/2 with the MCA bus are limited, but the IBM M-Audio Capture & Playback Adapter (M-ACPA) is somewhat easier to find and less expensive than the rest. It has a few quirks, but once set up properly, it sounds quite good. M-ACPA Option Diskette and Windows 3.1 & 95 drivers: http://tinyurl.com/macpadrivers
