TeleVideo Rises Again: Recreating a lost machine | VCFMW 16 (2021)
Channel: VCF Midwest
Date: 2021-09-20

VCFMW Founder Emeritus Pat Finnegan walks us through the process of reconstructing a system without any schematics.  After years of no success in finding a whole machine, in early 2020 a bare PCB came up on eBay that appeared to be for TeleVideo's first networked diskless Z80 system, the TS-80. This talk details the process of going from a blank PCB with design errors and no schematics or instructions to recreating the system from the PCB up through boot code to run TeleVideo's CP/M based networking environment.
