- A friend of mine just got hold of a 45MB MFM hard disk. He would like
- to use it in his Tandy 6000HD XENIX machine. Or I might buy it from him
- and use it in my PC7300 (3b1, UNIX PC) However, he bought it with NO
- DOCUMENTATION (oooh!) and thus does not know the jumper settings to
- change it from DRIVE0 to DRIVE1, or what any of the other jumpers mean.
- We NEED this information because it is currently set to DRIVE0, and it
- must coexist with the Tandy's built in drive, which is also DRIVE0,
- which basically means we must set it to DRIVE1.
-
- Any other information on this drive would be helpful as well (i.e.
- confirmation of what our idea of the disk geometry [heads, cylinders,
- etc] is)
-
- If youu know of this drive, please PLEASE get in touch with me through
- email.
-
- Attached is a description of the drive that my friend gave me over the
- phone.
-
- Thanks in advance!

- D3142 DISK DRIVE P/N 134-500558-531
- S/N 8951604193
-
- It's got 641 cyls, 8 heads and 17 sectors per track. The 17 sectors
- puts it in the MFM category instead of RLL.
-
- It's got two banks of DIP switches. One has 8 switches and is labeled
- BS8-01 The other has 4 switches and is labeled
- BS4-01. There are also 5 jumpers labeled JP5 thru JP9 as well as 4
- other, unlabeled jumpers. All of which are open. There is also a
- single jumper in another part of the drive with both its pins labeled
- (TP0 and TP1) that is jumpered. Oh, and on the DIP switches, both of
- the #1 switches are off and the rest are on on both sets. This drive
- was previously used by itself.
