Hi All, A friend arrived at my door with a HAL CRI 200 brought at a Ham Junk sale - does it work? - will you test it for me? - he said. The documentation talks of the TRS 80 computer and software that was in vogue back in 1984!! I love the Origami LED display hood. Anyone out there have an idea if the unit can still be made to perform? 73 Bob ZL2AMI
