I've got a Wangtek DC-300 tape drive (model 54590) and a controller with a 5.25" footprint. The controller has a 50-conductor edge connector keyed the same way as the drive connector, so I'm assuming that the drive is connected there. The controller also has a 50 pin male header. I believe the controller is also a Wangtek model WT05ZK. It's got an 8085A-2 on it, as well as the usual support chips (8257 DMAC AM9128 PIC). Chip dates are 1984. What's the interface to the controller? SASI? Anyone know what the command set might be? Cheers, Chuck
