New to the site are these 130XE specific RA adapter boards. Right now I am offering these on a pre-order basis. They compliment the Dual RA Cart Adapter board I already offer. I am also working on the details of a full 130XE Cart/ECI right angle switcher board. Just need to work out how best to deal with the various configurations of cart/eci devices.
Not to leave out the 600/800XL entirely I am also planing on offering a Dual T cartridge port adapter board. Hopefully in the next few weeks.
