- If you have some 96 tpi drives left over from your CP/M days, here's
- a way to put them to good use on your Z-150. They will provide 720k
- each of storage under DOS 2.11 or higher.
-
- 1) Your cable with 34 pin plug will plug onto the extra plug
- inside on the Z-150 disk controller. If you have a Z-158,
- you'll have figure out how to daisy-chain it to existing
- drive cables, since there is only one plug. If you have the
- 37 pin DB connection on the back of the disk controller, you
- don't have a Zenith, but once you figure out the hardware,
- the software will work fine.
-
- 2) For the Z-150 configure the drives as DS0 and DS1, NOT
- DS2 and DS3.
-
- 3) Edit the config.sys file on boot disk to include
- DEVICE=NEW96.DVD
-
- 4) Copy the device driver NEW96.DVD onto the main directory of the
- boot disk.
-
- 5) Boot the system and format some disks using FORMAT96.COM.
-
- 6) Please note that the Z-150 believes the drive numbers set on the
- system board. I declare only two disk drives, and that's all that
- DOS knows about directly. The external drives are handled via
- the device driver above. The Z-158 is a little different. It does
- a hardware check instead of checking switches, so it will try to
- use the external drives as C: and D: respectively. Without other
- drives about, the driver would use the external drives as E: and
- F:. One solution is to use one of the preboot programs that lie
- about the hardware extant. Otherwise, be careful not to use the
- drives C: and D:
-
- 7) If you use DOS 3.2 or higher, you don't need these files, since the
- ability to use 96 tpi coincides with the 3.5" support.
-
- 8) See the assembly listing for information on customizing.
