Jason Calacanis posted on X marking the 49th anniversary of the TRS-80 microcomputer launch by Radio Shack. The post detailed the device's original specifications including 4KB of RAM, 4KB of ROM, a keyboard, black-and-white display, and tape cassette storage, all priced at $599 in 1977. It included a video and asked who had owned one. In reply, Elon Musk stated that his first computer was a Commodore VIC-20. The exchange appears in public posts on the platform, with Musk linking to a Grok conversation sharing VIC-20 specifications.
