Hi! Thanks! Sorry for the many delays. I am very behind on projects and appreciate your patience. Here is the latest information on the free/open source SCSI to IDE and SD converter. Thanks to Wayne and other builders, the early prototype is working and can emulate a Seagate ST125N 20MB SCSI-1 hard drive. In theory, the S2I should be able to emulate almost any SCSI-1 device so this is really just a "proof of concept" indicating it can and does work. We are looking for additional builders to participate in the project to help expand the capabilities of the S2I device. Especially those with legacy SCSI-1 machines willing to build and test the S2I board. http://n8vem-sbc.pbworks.com/w/page/62549548/S2I%20Firmware%20Status http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=SCSI2IDE There are five (5) of the bare S2I PCBs available. The PCBs are gratis with the understanding the builder will build and test the S2I prototype board. Do you want a bare S2I PCB to build and test a prototype S2I? If so please send me your shipping address. Thanks and have a nice day! Andrew Lynch
