Lambda 8300 and Dragon 32/64, are electronic devices?
Dragon 32/64 The Dragon 32 and Dragon 64 are home computers that were built in the 1980s. The Dragons are very similar to the TRS-80 Color Computer, and were produced for the European market by Dragon Data, Ltd., in Port Talbot, Wales, and for the US market by Tano of New Orleans, Louisiana. The model numbers reflect the primary difference between the two machines, which have 32 and 64 kilobytes of RAM, respectively.
Hexbus The Texas Instruments Hex-bus Interface was designed in 1982 and intended for commercial release in late 1983. It connected the console to peripherals via a high-speed serial link. Though it was prototypical to today's USB (plug and play, hot-swappable, etc.), it was never released, with only a small number of prototypes appearing in collector hands after TI pulled out of the market. Several Hex-bus peripherals were planned or produced. A WaferTape drive never made it past the prototype stage due to reliability issues with the tapes. The 5.25-inch Floppy drive also never made it past the prototype stage, even though it worked. Prototype DSDD disk controllers and Video controllers were also made. A 4-color Printer-Plotter, a 300-Baud Modem, RS-232 Interface, an 80 column thermal/ink printer, and a 2.8" "Quick Disk" drive were the only peripherals released in quantity, mostly for use with the TI CC-40. All Hex-bus peripherals could be used with a TI-99/4A when connected through the Hex-bus Interface, through direct connection to the TI-99/8, or through direct connection to the Texas Instruments Compact Computer 40.
