FW: [N8VEM: 15283] Re: SCSI2IDE Progress

Hi! I think this is of general interest to the vintage/classic/hobbyist computer community. We are getting very close to a fully functional free and open source SCSI-1 to IDE (including CF adapters) and SD bridge board. There have been several discoveries during the build and test phase and we will be getting a second set of prototype boards soon that include all the fixes (including optional terminating resistors, various fixes and improvements, etc). Please see the photos of the test harness and the board responding to a PC SCSI-1 controller identify command. This board is being targeted to the most oldest SASI and/or SCSI-1 equipped machines. Generally speaking newer SCSI drives are still available and/or commercial SCSI to IDE bridges exist already so this board would not be necessary. It is primarily intended for the most ancient SASI/SCSI-1 machines such as early Mac, Atari, Amiga, Apple II, DEC, Sun, Apollo, various CP/M single board computers, sewing machines, synthesizers, lab and/or test equipment, etc with specialized SASI and/or SCSI-1 requirements. Occasionally these older machines require specific SASI and/or SCSI-1 drives to operate which may no longer be available. Since the bridge board is free/open source the identification strings and/or firmware can be modified to emulate these older devices. Thanks and have a nice day!

Still a long way to go, but this is good stuff. I have been able to exchange data with a host initiator to the point where the host knows the target is there and basic information like it's name and capacity. Here are links to some pictures I just posted on the Wiki. I can see the host asking for a "READ DATA" command now, but have not had time to implement it, but very close. S2I Test Harness <http://n8vem-sbc.pbworks.com/w/file/fetch/62651425/2013-01-13%20S2I%20Test% 20Harness.jpg> shows my SCSI2IDE board connected to my Xi 8088 (thanks Sergey!) via a Future Domain SCSI Controller. S2I LUN Discovery <http://n8vem-sbc.pbworks.com/w/file/fetch/62651421/2013-01-13%20S2I%20LUN%2 0Discovery.jpg> shows a boot screen demonstrating the Future Domain Controller BIOS finding the SCSI2IDE board and successfully determining it's sector size. SCSI2IDE Board <http://n8vem-sbc.pbworks.com/w/file/fetch/62651429/2013-01-13%20SCSI2IDE%20 Board.jpg> just shows the board itself.
