[TURBO232 - FEATUREREQ] #419

Open emanuelelaface opened 1 month ago

emanuelelaface commented 1 month ago

The current implementation of ACIA 6551 is with the Swiftlink protocol that reaches a maximum speed of 38400 baud. The same chip was used in the Turbo232 UART cards, such as the GLINK232T reaching a speed of 57600, 115200 and 203400 baud. It can sound useless for a Commodore 64 but there is an amazing project of BBS (https://github.com/retrocomputacion/retrobbs) that is capable to stream audio and images at the maximum achievable speed, and especially the audio quality would greatly benefit from higher speed of the modem.

This is the schematic of one card that implements the Turbo232: https://gglabs.us/sites/gglabs.us/files/glink232-C01.pdf

It may be more beneficial for the Retroterm maintainer to add support for the Ultimate network (tcp/ip) stack instead.
