> What is a BBS? You're joking, right? BBS = Bulleten Board System Before the Internet was publically accessable, most people that were online were either using a commercial service such as Compuserve, or BBS's. Some BBS's were free, others charged for access. There were even "Networks" of BBS's such as Fidonet that shared email and message boards. Everything was done via dialup, often with very slow modems.

Items FS

by pat＠purdueriots.com

I've got things that still haven't been claimed from last time yet. I'm asking $5 plus shipping costs each item. First, the new: - PowerMac 6100/66 with 250MB hard drive, cdrom, and DOS card (with dongle for the DOS card). I think it has 16MB RAM. - Compaq Luggable (original model). Has 2 FH 5.25" floppy drives. - Zenith XT clone with 10MB hard drive, and 360KB floppy drive. Tested, works. - DEC LanBridge, not used, pair of AUI connectors on the back. Now, what's left from last time, and probably going to get thrown out soon: - Macintosh Classic II. 80MB HDD, not sure on amount of ram. - Macintosh Plus 1MB - Macintosh Quadra 700, 16MB ram, 230MB HDD. - Mac-plus style keyboards and mice (4pin RJ11 keyboard, DE9 mouse) - PS/2 Model 70, with 6MB ram and an 80MB hard drive. I have at least two to get rid of, but need to find where I stuffed the ram first... - 2 Full-height 50pin centronics SCSI enclosures - HP 9000 model 715/50, I think it has 32MB ram.

>theres no header on the data tapes (IIRC) That's a simple fix. Actually, if that is the only reason an audio tape isn't usable, then I can custom order tapes from a supplier I use in the correct length (600 feet) and with no leader. I don't know the price for sure, but I would venture to say no more than $2.00 per tape. (I get normal 120 minute tapes from him for about 60 cents a tape). Somehow I suspect there are other reasons beyond tape length and lack of a leader that makes it different from an audio tape. -chris <http://www.mythtech.net>

>I have a number of data cassette tapes still in original packaging. A maxell >CS-600XD says 600feet length, 16,000ftpi and D/CAS-86 compatible. Have no >idea what that means. Well, at least it gives me the specs to find a compatible tape. In doing some more searching, I'm having a very hard time finding anyone that actually still sells the tape. A few people still list them, but so far no one seems to actually have them. Probably because from what I can find, Maxell no longer makes the tape. Any chance you might want to part with one tape on the cheap? Although, honestly, if I can't find a supplier for tapes, it won't really matter if the drive works or not. Maybe I'll just stick an audio tape in it and see what happens (found a newsgroup posting that says not to even think of doing that... but they don't say why... if the universe implodes tomorrow, you can all blame me for using a cheap audio tape in the drive) -chris <http://www.mythtech.net>

I just aquired a ClubMac tape drive that I want to test. It is a rebadged Teac MT-2ST/N50 cassette drive. I'm hunting around for info, and it looks like that uses a 600XD cassette. A regular audio tape cassette fits in it. Does anyone know if I can use regular audio tapes? Maybe a particular style of audio tape? I really just want to test the drive to see if it works, so if an audio tape will work long enough to write some data and read it again to make sure the drive functions, that should be enough. I don't really want to plunk down $15 for a data cassette for it to find that the drive is dead. -chris <http://www.mythtech.net>

I think the coercivity of these tapes is about 600 >oersteds (which makes them Class II); normal audio tape is about >280-320 (Class I). Interesting about that notch. I tried fitting an audio cassette tape in mine last night, and it inserted and allowed me to close the drive (flip the locking handle to the locked position). The link indicates that I shouldn't be able to close the drive without that notch being present. I didn't examine the mechanism as it locked, so it is possible that it has a fail safe and although the handle showed locked, the transport in fact wasn't. Or of course, the previous owner may have forced it locked on an audio cassette and broken the transport. I guess I need to open the drive again tonight and take a look. It does give me hope that you think the tape might be in the range on an Audio Class II tape. Those are easy and cheap to come by around here. The local Tower Records sells them in lengths from 30 minutes to 120 minutes, with all sorts of odd "match the CD" lengths in between. They are usually in the $1 to $5 each range depending on brand, quality, length, and number in a pack. I should take a look there tonight, I almost wouldn't be surprised if they sell D/CAS tapes (if they were used in audio equipment at any point, chances are Tower has a few of them). -chris <http://www.mythtech.net>

Probably. I have some 30/60MB Verbatim ones, which *do* have a leader. I suspect they'e a different coercivity from normal audio tape. However, I think the warnings about not using audo tape come from the fact that cheaper audio tape used to be reknowned for being a little abrasive, and for shedding oxide, which is not very good for streamer performance. -- Pete Peter Turnbull Network Manager University of York
