GoKawiilDeveloper recreates 1993 Mexican BBS session using homebrew Z280 computer logs
Óscar Toledo G. has published a session replay of La Cueva BBS, a Mexican bulletin board system he accessed in 1993 using a homebrew Zilog Z280 computer and a discarded 2400-baud Hayes modem. He wrote his own serial terminal program from scratch, implementing RS-232C communication, AT dial commands, and ANSI escape sequences based on information from books rather than the internet, which did not yet exist for him. To handle discrepancies between documented standards and real-world BBS behavior, he built a capture buffer using the Z280's MMU to record raw byte sequences as they arrived.
