....I get this on-screen error message: '5ur' or maybe instead of a 5 is a capital S 'Sur'...the manuals do not mention anything about this error message which is rather strange since they mention others, ....this has me puzzled.
Just for the record: I had the same issue on a newly acquired SB-55 and it happens when you try to use a floppy formatted to 1.44 instead of 720k. You have to cover the hole on the lower right hand side of the floppy and format as 720k, that's all .
I had the same issue of the SB-55 saying "Sur" on the display, turns out my floppy disk head was jammed. Opened it up, gave the floppy head a nudge and it started working beautifully.
And I would like to reiterate the above, along with, make sure that you transfer the files using a floppy drive designed for 2DD (double density) disks. Some of the newer 1.44 drives do not natively support 720k DD disks, and if you take a 720k disk and try to format it using "format a:" command, the drive will error out saying Track 0 (zero) is bad, disk unusable. I found that out after spending a whole day trying to get my SB-55 to read a disk ... 😀
I hope this helps someone who's in the same situation as me. Made an account on Vogons just to share this experience 😀 ... by the way, love Vogons, I've been reading stuff on it since the past year an a half, lovely community !
