ah the MacCharlie and the Amiga Sidecar, both horrendously overpriced for their respective markets. Though the Amiga peripheral arguably did a much better job owing to the host system's ability to both display color as well as multitask natively, so one could use both environments simultaneously. I believe even possible to exchange data between the two while both were rinning, due to the use of dual-port RAM on the Sidecar and some sort of simple driver running on both sides handled mutexes, locks and such.
