Dear Stephen or anyone needing one
I have one.  Here is the info on it and the history behind it.
Make: VG ISOGAS
Model: Analogue Display Unit (IS1044)
Year Built: 1987
Power: 240 Volts, 50-60HZ
Price $17 000 CDN
Warranty: 90 Days,  off-site warranty, on delivery of unit.
Shipping : Federal Express or UPS (billed to receiver), insurance is up to
you (about $200CDN for that amount)
Features: 1) Front Panel
              - 3 analogue output meters with Gain control for reading of
three collectors
              - Change-over valve R/S LED status lights, toggle switch and
Isolate/Normal switch on front panel
              - Two channel analogue chart recorder controls for: OFFSET,
Amplifier GAIN, choice of what to monitor (Maj, Min1, Min2, Min1/Maj,
Min2/Maj)
               2) Back Panel
               - Valve banks: 3
               - Motor control:2
               - DAC (for manual HT units)
               - VFCs: 6 with 4 active (3 collectors and one spare (e.g.
0-10V EA output))
               - 5 pin DIN for Chart recorder
               - Interfaces: HPIB, RS232, Unit I/F (Source & HT ribbon), 2
Local I/F (for daisy chaining 2 controllers)

The unit was purchased along with a Source Control unit and a used SIRA-9
with the hopes of modifying it into a dedicated dry-bath water
equilibration machine.  Since getting our new equipment (Deltaplus), the
plan was to sell one of our SIRA-12 to make room.  I decided against it and
dismantled the SIRA-9 for spare parts and kept the SIRA-12 instead.  I
built a rolling water bench that is hooked up to one of the SIRA-12 with an
AB-switching box using its existing System Controller to go from manifold
to autowater.
The System Controller Unit is new and has never been used.  It will be
fully tested on one of my existing machines for warranty purposes.  This
unit is the same as those used on the VG PRISM SeriesII, SIRA-10 and SIRA
SeriesII as well as on previous PRISMs' without the front panel analogue
outputs.
If you have any further questions, please fell free to ask.

Best Regards
Gilles
