OK, jumpers now make sense, QT software explains them in the HELP 
script. Still, problem is that the QT60i and QT125e drives  don't 
seem  to work with the Wangtek full length card. Is that the  PC-
36? What's the Tecmar 1/3 length card known as (it's not the  PC-
02 as I have one of those).

Finally,  a  rhetorical question: why are different  tape  backup 
software  packages incompatible? Was there no  standard?  SYPLUS, 
QT, ARCSOLO all seem to store data in their own ways.

David,

that's any sort of QIC-02/36 adapter. Although most vendors showed
only their own, there are many manufacturers of them and many
revisions .... So, even if you don't find the board in your help
files, it's very likely that all jumpers are the same...
Anyway - most QIC-02 adapters doesn't work with fast PCs - i tried
with 4 different boards and, with all tricks tried,  none worked in a
P90, but all worked in a 386/20....

Thanks.

I now have Wangtek drives a  2 x 5150EQ
                          b  1 x 5125EN24 (QT-60i)
                          c  2 x 5099EN24 (??????)
                          d  1 x ????     (QT-125e) 

Controllers               a  Wangtek PC-02
                          b  Wangtek PC-36 Tecmar ROM 
                          c  Wangtek Pc-36 Wangtek ROM
                          d  Tecmar 938469 (like PC-02)
                          e  Compaq (like PC-02)

Am I right in assuming that the 5125EN24 and 5099EN24 drives are 60MB?
They work with the Wangtek PC-36 in a 386/20 desktop, but the 5099EN24
will not work with the Tecmar PC-36, at least, it fails a write test.
The Tecmar ROM based Pc-36 has a different jumper configuration for
W2 and W3 to the straight Wangtek PC-36. In the Tecmar Pc-36, W3 is
jumpered, whilst in the Wangtek PC-36, W2 is jumpered.

I only have a manual for the PC-02 not PC-36.

I really need to know what the difference is between the 5125EN24 and
the 5099EN24.

Finally, whilst faster than 386 can be a problem, pentiums are
right out......I am having problems on a Toshiba 5200 expansion box.
I note that in the expanion box manual there is some reference to 
pull up resistors on he DMA lines. Should I try turning that option
off?

I am trying to come up with a workable combination of drives so a 
friend can back up on one 386 machine, and I can read the tapes here
on another. Clearly his will have to be a 60 or 125, but I don't
know what the 5125En24 is....

The Toshiba 5200 Expansion Unit provides 5 extra 8 bit slots. Plugging
the PC-36 or PC-02 gets some response from external drives, but when
it comes to WRITE operations or restore, the units just hang. There
arer NO other cards in the expansion box so it can't be an IRQ or
other conflict. The cards are set at 300Hex, IRQ3 (tried 6 and 7) and
DMA 2 or 3. It makes no diffrence.

Does anyone have any suggestions as to why a DESKTOP 386/20 presents
no problems but the Toshiba 5200 and expansion unit does? The only
things I can change on the interface is whether or not pull up
resisters are on the DRQ lines or not and the bus speed being 4.77 fixed
or the speed of the 5200. It's currently on speed of the 5200 bus.

Someone has kindly help out with an account of what the 5125EN24 is, ie
a 120MB streamer which uses the PC-36 interface. Odd thing is that this
drive runs with the Tecmar ROM based controller but not the straight
Wangtek Pc-36. The two boards seem the same apart from the EPROM and W2/3
settings.

Does anyone know for sure what mechanism the QT-60i has? maybe the front
plate has been switched? A more suitable candidate for the QT-60i would
be the 5099EN24 surely?

The 5125EN24 is 15 tracks (125MB), the 5099EN24 is 9 tracks. If the 
controller is writing 15 tracks, your 5099 will fail.
