I have a Victor 9000 I'm restoring here, and I
have
a few questions:
1. Where do the two plugs for the 5 1/4 drive heads
connect? This system
has the Universal bios, a 10MB winchester HDD with
DOS 3.1x and the
later 1.44MB GCR/MFM floppy installed, but I can
only seem to get one of
the drive heads working (using catweasel on PC to
dump a 'formatted'
disk afterwards results in clear data spikes on one
side and the other
side blank, and format.exe won't format disks
properly unless given the
/1 1-sides flag)
2. The victor 9000 does NOT say anything when I turn
it on. I know the
Sirius 1 did, but I'm not sure the Victor does. Is
this normal, or does
the system need the HC-55564 delta modulation chip
replaced?
3. Does anyone have a schematic or service manual
for the victor
9000/sirius 1 anywhere?
I think I have a service manual *xeroxed* for the
Vic9K, but it's in another state, as is my brain half
the time. It won't be in my hands in all likelihood
for 4-8 weeks. Sorry, I know that's a long time to
wait, but that's all I *can't* do for ya now.
I also discovered that both of the victor keyboards
I have need
re-foaming between the contact discs and key
plungers, which is gonna be
a whole bunch of fun to do.</sarcasm> They also both
need new snap-tabs
on them as both of the tabs have the tooth broken
off (though they work
fine other than having to hit keys really hard and
the cord occasionally
falling out of the computer)
A thorough cleaning is in order before you replace
all that. I bathe my keyboards in a 10-15% solution of
ammonia and water. I haven't yet disassembled a V9K
keyboard, but I imagine it's typical as far as
keyboards go. Remove the plastic and toss it in. If
you need more details, I'll provide. It works well.
P.S. Does anyone have dumps of the older BIOSes for
the system? The
universal one is the 'last' one of at least three I
know existed. More
than one version of the universal one may exist. The
one I have is
labeled 'V9000 UNIV. FE F3F7 13DB' and 'V9000 UNIV.
FF F3F7 39FE' with
respective crc32s of 25C7A59F and 496C7467 for each
ROM. The sum16s
match the last part of the labels, i.e. 13DB and
39FE.
I have a Vicki in my present possession and 2 V9Ks at
the other location. I don't have a working boot disk
unfortunately. I'm assuming the drives in the Vicki
are the same as the V9K's, so if you can provide one,
I'll provide you with whatever it has.
I was told my roms are *older*. That's the extent of
what I know.
