So the replacement caps arrived today.  It turned out that while one of the tantalum capacitors on the main board had failed short, some actually seemed ok.  However I replaced the lot as a couple more had odd readings and there are only 9 of them anyway.  Powering the board up I actually got some output, though it's garbage with a flashing cursor a 3rd of the way down the screen.  Still, not at all bad for a computer that has sat idle for 25 years.  I'm thinking a short on the data or address bus, or maybe a faulty ram chip.
