I have not seen any Commodore 8" drives in person (though I'd love to have one). Even when my daily-use computer was a PET (1979-1983), I knew all about Commodore's 5.25" drives but had never heard they ever made 8" drives. It wasn't until I was browsing the firmware directories on funet that I learned of them. >> the later 8061, 8062 and 8280 were all dual >> drives and could read IBM 3740 as well as Commodore GCR format. > > Does that mean, the 8060 can't read the IBM 3740 format? The IBM 3740 format is nominally 250KB (single-sided, up to 77 tracks of 26 sectors of 128 bytes), so it suggests that a single drive that's capable of 750KB, even allowing for double-sided media, isn't a 3740-compatible format. Other than that, I have only that declaration to go on for media compatibility (or lack thereof). As long as the drive mech is 48 tpi and the read/write circuitry can handle FM data, I would think that the limitation could be firmware-related. If those hardware conditions are not so, then it's likely that there's a hardware issue at work here. >> and the 8280 1MB. > > Okay, this drive is not so interesting, because a own it. Do you have any pictures (especially of the inside)? -ethan Message was sent through the cbm-hackers mailing listReceived on 2011-09-07 17:00:03
