Title: TRS-OS: A New TRS-80 Operating System
Website: https://danielpaulmartin.com/home/research/
TRS-OS is a resource sharing OS executing on Zilog eZ80. It translates most all bit level driver communications between TRSDOS and its new host hardware (eZ80). Running up to 5000% faster and 256 times RAM over original Model 4D. Most all TRSDOS applications I have tested work perfectly with exceptions of things flying by to fast (delay loop problems). I offer 3 different session connection methods depending on degree of video & keyboard reproduction you require. TRS-OS is executing on Zilog eZ80 processor @50Mhz no wait states. Two 360k RAM disks, 2 UARTs, lots of general bit I/O & make this like a model 4D on steroids. This new platform executing my favorite DOS will be embedded in various pieces of equipment for projects (wind/solar & hydro). Do you have a eZ80 project you would like to execute TRS-OS & its guest OS(s)? In dedication to this launch, Daniel Martin has donated from his personal legacy collection one original XLR8 to raise funds at TA 2022 auction. I have located original manuals and disks for this product and they will be available at auction. Please bid briskly and high for TA. Let this be in dedication of making TRSDOS live on in new processors. Last year I meant to bring XLR8 to sell and many were disappointed. I told you that I would give everyone fair chance, be warned, your chance is TA 2022. What’s next Zilog? TRSDOS is ready. Long live TRSDOS!
