Hello,
I am having trouble interfacing an HP 9134 HDD to my HP 85. I have connected
other drives without difficulty such as the 9121D so I believe the computer
is set up properly.
I recently picked up a 9134A HD. It apparently emulates a 9895A 8" flexible
drive and 3 slaves each with 1.15MB capacity.
I'm not sure that the 9134A will work, you may need the 9133 or 9134 VX model.
I've seen a great deal of contradictory info in the HP catalogs and manuals. According
to some docs you also have to have the correct option. On SOME models there is a switch
inside that can be used to set the 9895 emulation mode (that's all there is to the
option). Some VX models have the switch and some don't. After YEARS of looking
I've finally found one and maybe two of the right models. One of them has problems. I
just got the other yesterday and I THINK if has the necessary switch but I haven't
opened it to be sure.
I just dug out my HP 9000 series 200 configuration manual and it says that the 9134A
does use the Amigo protocall and will emulate four 9895s. It also says that the option
010 drive is a single unit (ie one 5 Mb drive) so if your's is a 010 then you need to
change the switch setting.
I set the HP-IB address to zero on the HD and typed MASS STORAGE is ":D700".
Try using "D700,0", "D700,1", "D700,2" and
"D700,3", That will address the individual logical drive units.
I then typed CAT and Initialize and keep getting a
"Timeout". Also if I turn
the 85 on with the HD connected and running and type CAT the HD does not
respond as my 9121 would without typing a mass storage is command.
Can I assume the drive is bad or am I using the wrong syntax. The drive
spins up nicely, and the light comes on but I get that error message and the
disk access light does not come on.
Turn off the drive, unplug the HP-IB cable, turn the drive on and it will do a self
test. If the fault light goes out and the power light isn't blinking after about 1
minute then there's about a 99% chance that the drive is good. (Note: the power light
may go off or it may stay on, different drives are different.) If you get any abnormal
indications then the drive is probably bad. HINT: on some (all?) HP HP-IB drives the heads
will park automaticly after the self-test if you power it up with the HP-IB disconnected.
A handy thing to keep in mind before you ship or transport the deive.
I hate to toss this drive into the dumpster if it is functional.
Don't toss it if it self-tests ok. It can still be used with other HP computers.

Thank you for your thoughts.
