I'm happy to announce the availability of a new all-in-one SIO2PC interface that combines SIO2PC and ProSystem cables into one low cost, jumperless and auto-switching interface.
Interfaces are available with real Atari SIO jacks, or with terminals. The SIO jack model will probably be a limited production, I doubt I will be able to get many more of the SIO jacks.
Prices for the first 100 standard interfaces sold are only $19.99.
Complete documentation for the interface along with photos and PayPal order form can be found at
