These tape drives have been reported as working (or not working) on
386BSD or NetBSD, either in articles on USENET or in response to
previous postings. If you know any more details, want to point out
errors, know another tape drive works (or doesn't), have any
suggestions for additions/changes to the FAQ, or anything else
useful, please send your reports to:
andrew@oti.on.ca (Andrew Cornwall) or
rsk@ecs.soton.ac.uk (Bob Kemp)
PLEASE HELP TO UPDATE THIS LIST BY PROVIDING COMMENTS AND NEW
INFO. IN RETURN, WE WILL POST UPDATES AND TRY TO MAKE THE LIST
AVAILABLE TO ANYONE INTERESTED.
IMPORTANT DISCLAIMER:
This list is not guaranteed to be 100% correct.
We don't know much about tape drives as yet, so
we are only collating information provided by others.
By getting feedback on this list, we hope to improve
it into an FAQ.
EVEN MORE IMPORTANT THANK-YOU:
Thanks to everyone who's contributed to this list. Without
your help, it wouldn't exist!

COMPATIBLE TAPE DRIVES:
Format of each entry is as follows:
Name: {name of the device; if you're reporting, please be as
specific as possible}
Capacity: {Maximum size of the device}
Approx Cost: {Roughly what you paid}
Interface: {How it talks to the machine - SCSI, PC bus, etc}
Controllers: {What controller you're using - Adaptec 1542B, etc}
Informant: {Who says it works}
Comments: {Anything good or bad you feel like saying}
Name: Archive 2150
Capacity:
Approx cost:
Interface: SCSI
Controllers:
Informant: ejh@slustl.slu.edu (Eric J. Haug)
Comments: works well with both the driver in the distribution
kernel and julians' SCSI drivers.
Name: Archive Python 4???
Capacity: 2GB on 90m tape
Approx Cost: US$1149
Interface: SCSI
Controllers: Adaptec 1542b
Informant: admerlev@cip.e-technik.uni-erlangen.de (me 8-))
Comments: nice device!!!, works like a charm, tar w/ original
scsi-driver plus variable block length patch, under DOS:
GTAR, ASPIBIN (ASPI-TAR), PCTOOLS 8.0, COREL-SCSI
Name: Archive [exact model unknown]
Capacity: 60Mb
Approx Cost: US$1800 list price (4-5 yrs ago)
Interface: SCSI
Controllers: Adaptec 1542B
Informant: sjg@melb.bull.oz.au
Comments: [Came with sun386i. It has an] emulex board [that]
acts as an embedded controller (like SCSI disks have).
The drive is good for 5Mb per minute I believe which is
also what my 1542b is set for. Certainly the tape
steams _very_ well, much better than it ever did on the
sun386i!
Name: Cipher Model 540
Capacity: 45M/60M (probably/hopefully)
Approx Cost: Loaned to me in `vintage appearance' (Much dust) - No idea !
Interface: SCSI 1
Controllers: Adaptec 1542B
Informant: Julian Stacey <stacey@guug.de>
Comments: Shows promise, Cant yet call it truly usefull though:
The Good Bit:
I have seen it stream constantly on 386bsd.
The Bad Bit:
I can't use it as a usefull drive because it keeps
dropping out with errors.
The fault does not lie in the media, & most probably
not with external power supply or scsi cable -
I'm working on it.
Name: Cipher ST-150F
Capacity: 150Mb
Approx cost: US$300 (incl. interface)
Interface: QIC-02
Controllers: Cipher
Informant: hideki@isl.rdc.toshiba.co.jp (YOSHIDA Hideki)
Comments: works well with blocksize <= 4b
Name: COMTEK Gigatape 1200 4mm external DAT
Capacity: 1.2 Gb
Approx Cost: US$800
Interface: SCSI 1
Controllers: Adaptec 1542B
Informant: Rich@rice.edu
Comments: Uses formatted, fixed blocksize tapes. Only
partial success writing about 400Mb so far.
Name: Sankyo ST525
Capacity: 525 Mbyte
Approx Cost: 6000 SEK (US$850)
Interface: SCSI (SCSI-2)
Controllers: Adaptec 1542B
Informant: jonas@carmen.volvo.se (Jonas Lagerblad)
Comments: everything works allright except for one crash
The SCSI bus seemed hang after running
"dump 0uf - /dev/rsd0a | gzip --best | dd of=/dev/rst0 bs=64k"
for approx 1 hour. If I skip the compression everything works
perfectly. (I am using Julian's SCSI driver)

Name: Tandberg 3820 5 1/4" HH internal QIC 525 SCSI streamer
Capacity: up to 520Mb (depending on media) uncompressed
Approx cost: (I bought mine two years ago--it wasn't cheap :-)
Interface: SCSI-1/2
Controllers: I used the AHA1542B
Informant: tmh@first.gmd.de (Thomas M. Hoberg)
stacey@guug.de (Julian Stacey)
Comments: Works well with both the driver in the distribution kernel
and julians' SCSI drivers. Reads all QIC media (tested
QIC 40/60/120/150/525) Writes QIC 120/150/250/320/525
(120/150/525 tested) Includes a 256k buffer. 2 rw
speeds: 83k/s for QIC<320, 200k/sec for 320+
Occasionally the file system can't keep up at
200k/sec on backups (small files), somewhat more often
on restores. The drive can directly seek to any block
on the tape, so in theory at least with the
appropriate device drive you could mount a file system
on it (you better keep fragmentation low :-) As you
can guess, I am EXTREMELY happy with it.

The Good Bit:
It streams constantly without error (~40mins for 525M
write @ 60K blocking). Tape drive shares bus with 3
SCSI-2 Seagate drives also OK with a SCSI-1 Micropolis 1684-7.
The Bad Bit:
We (several us of using these TDC3820s on different hardware)
have undergone an eerom + eprom autodensity upgrade to allow
150M writes (previously could only read 150M tapes +r&w 525M);
this known as Revision 04908, Done 92 08 28.
There is some kind of block size problem that prevents
us reliably exchanging 525M tapes, 150M seems OK,
problem is tape hardware oriented I believe,
not 386BSD specific.
Problem pre-existed the 150M write capability upgrade.
A friend with same 386bsd + TDC3820 + 1542A cant read my tapes,
neither can a PCS (M68000 based) computer with a TDC3820

Comments: Works great with Julian's SCSI drivers and an Adaptec 1742...

Comments:
Name: Wangtek 5099SC24, this is a QIC drive (same mechanical drive
as 5099EN24) with a QIC24 to SCSI board by wangtek full height
Capacity: 60Mb w/DC600A, 100Mb w/DC6250
Approx cost: Used as is drives US$25.00/each, refurbs ~US$100.00
Interface: SCSI
Controllers: Adaptec 1542B
Informant: rgrimes@agora.rain.com
Comments: works well with both the driver in the distribution
kernel and julians' SCSI drivers. Very old full height
driver readily availiable in the surplus market. I know
where there are 50 or so of these for $25.00/each as is,
they are pulls from old workstations.

Informant: berry@max.IN-Berlin.DE (Stefan Behrens)
Comments: [With original 0.1 SCSI ...] it streams constantly and
works without any errors. The tape drive is the only
device on the SCSI bus. It works great with the
original as drivers. But with Julians new st stuff
there are a lot of problems. I can read from the tape
but writing usually does not work!
Name: Wangtek 5525ES
Capacity:
Approx cost: US$600, CDN$1000
Interface: Adaptec 1542B, Adaptec 1742

andrew@noware.ocunix.on.ca (Andrew Cornwall)
Comments: Writes QIC120, 150, 250, 525. Reads QIC24 as well
(untested). Works with the distribution kernel.
