2.8M runs at 1,000,000 bits per second. Such controllers exist, but are not very common. Can Catweasel/kryoflux handle that data transfer rate? On Wed, 24 Jan 2018, Jason T via cctalk wrote: Looks like no on the KF: https://forum.kryoflux.com/viewtopic.php?t=198 The post is from 2011, but as

Interest in Teac FD235J drives and FC-1 boards?

I've got a fellow with a stock of Teac FD235J (2.88) drives and about a dozen bare Teac FC-1 SCSI boards. I'm trying to gauge interest--I don't think he wants to sell them onesy-twosy, but I'm willing to act as intermediary for single-unit purchases if there is sufficient interest. --Chuck
