Heathkit 3400A information needed

Also, there was a 3400A up for sale on ebay a while back, including a peripheral expansion system. I've already done an exhaustive search on ebay but came up with nothing, ebay only keeps record of auctions within the past 2 months. Does anyone have any information about this expansion system? I'd like to try to build one. I've got all the docs on the 3400 and the eta-3400 (the expansion accessory) and I'd be happy to provide copies. The eta-3400 adds Pitman tiny basic, some more memory, cassette i/o, and a terminal interface to the trainer. I'll check the doc pile when I get home from work... Regards - Mike: dogas(a)leading.net
