In this video we refurbish two odd TRS-80 Model 100s. One of them is a one-of-a-kind prototype from the estate of Tandy engineer Frank Druda (thanks to my friend Eric D.). Second M100 has an odd ‘blonde’ keyboard. Let dig into both and see how much the prototype differs from a production unit and get them both fully operational again. Both units will be at Tandy Assembly 2024: http://www.tandyassembly.com/ https://youtu.be/VFmqBiETwmY Jeff Birt (Hey Birt!)
Malcolm Ramie has what I think is the counterpart to this prototype unit, an external EPROM board owned from Frank Druda, for the Model 100. Malcolm was told the external board was used by Frank to get updates for the OS on the Model 100 during development. The board was shown at VCF-SW 2024, and I dumped the ROMs, though the ones on the PCB are the same as the production OS. Someone might have received earlier ROMs loose from the estate, not sure. This ties to the earlier questions I asked on the list: http://lists.bitchin100.com/private.cgi/m100-bitchin100.com/2024-June/089869.html Jim -- RETRO Innovations, Contemporary Gear for Classic Systems www.go4retro.com store.go4retro.com
