Oops, I stand corrected, thank you!
I looked at the MAAM website but could find no further news on the Viscount since the 2000 update you provided a link to, indeed the website doesn't seem to have anything more recent than 2004 on it.
Interesting that it has an APU, never met one of those before, I don't believe it was original manufacturer's equipment, we just had to have a very large GPU that pushed out large amounts of 400cps power to start the engines with, you might just get one started on the battery with much juggling of the HP cock and fuel trim switch, if you were lucky.
