It's $60 shipping inside the US, so $100 shipping sounds like a bargain. However, if you'd like a full-szied 10.5" reel, these aren't that. Look like 600' reels, rather than the full-length 2400' ones. --Chuck

Quoting Anders Nelson via cctalk : Here is a 10-pack of 9-track tapes for $10USD: https://www.ebay.com/itm/BASF-9-Track-Mag-Tapes-Brand-New-Case-of-10/112152910883 Shipping to NZ will probably be $100... I bought one of these boxes and could send you a single tape if you need it, but I imagine there's someone with a tape they don't need closer to you. The shipping guess was damn close - $97.94 (approx. NZD143.54), plus US$10 for the actual tapes. It actually sounds like quite a good deal, for brand new tapes. Thanks for the offer of the tape, if I get stuck I'll drop you a note. Cheers, Mike
Re: Burroughs BU4400 tape drive. What is it?
Quoting Chuck Guzis via cctalk : If you're going to use this thing, do check the carbide (sometimes ceramic) cleaning blade. You want the edge to be sharp and smooth; if it's nicked or chipped, it will end up doing more harm than good. In this case, it's really just for show - I don't have a real 9-track drive, or any tapes. That was why I'd prefer an unusable tape, rather than destroying a good tape by passing it through a cleaner repeatedly. However, tapes do seem really quite cheap and easy to find. I suspect that a carbide insert for machine tools might be cobbled up as a replacement, if required. I suspect the blade is actually missing. There's am empty spot that looks like it might have taken a cartridge at once point in the tape path. Maybe nothing actually goes there, but on the tape path diagram, it seems to show something with a narrow gap the tape passes through. If I wanted to make it functional, I could fairly easily make a cartridge that fits in the spot as above, and passes the tape across a blade of that sort without a great deal of pressure. I would really like a working drive sometime, so I am actually considering doing this... Cheers, Mike

Burroughs BU4400 tape drive. What is it?
Hi all, I just bought this Burroughs BU4400 tape drive: https://www.trademe.co.nz/Browse/Listing.aspx?id=113439 As the seller says, Google comes up empty. Seems strange, I would have expected some reference somewhere. Does anyone know anything about it? I'm going to pick it up this evening. It'd be superb as a display piece, but I'd be really keen to drive it with something and get it reading and writing. On that topic, are there any suggestions on how I could get my hands on a few tapes, preferably with a format this drive can read? The actual contents aren't important; even blanks would be OK, though not being able to get it reading before moving on to writing would make the project more difficult. Cheers, Mike
