Hello, I managed to repair the SCSI board of my tape unit. In the end it was fairy simple, just one bus buffer not working as expected. On SCSI board I have ROM 193996 rev 10, while on control board ROM 123248 rev 30 and ROMs 123615/123616 rev 06. Could worth to update it for better tape reading support or compatibility? Anybody has some more recent ROM? If anybody is interested, I can share the ROM images. Andrea
