Chaps, I've been testing the 6532's I received from China and so far they all work except one which is a partial fail. I have been testing them in my working SFD-1001 by doing a few load/saves and then running the SFD-1001 "PERFORMANCE TEST" program off the 1001 Test/Demo Disk. This formats a disk, writes some files, reads them, writes and reads from tracks 0 & 154 and deletes the files. Originally I was testing 2 chips at a time then the next 2 and so on until I got to thinking that maybe the drive never made full use of the facilities of both RIOT chips so I went through the whole process again but this time i tested, swapped the two RIOT's over and tested again. Sure enough, of the 13 chips I have, I have found one that works in 4J but not 6J. All the rest work in both positions. A couple of questions: Does anyone know the internals sufficiently to tell me what aspects of the RIOT functionality is not utilised by the two in the SFD-1001? Do people think this is a thorough enough test or is there a better approach to testing them? (given that the only hardware I have that uses them is IEEE drives) Does anyone have a file copy utility for a PET with daisy chained IEEE devices? I want something to copy between devices, not drives in the same device. Regards, Rob Message was sent through the cbm-hackers mailing listReceived on 2012-07-09 23:00:05
