Hi,
I've read about the Northstar 8/16 board, which came in two versions. One was an S-100 board, the other board fitted in a Northstar Advantage case and attached to the motherboard. From what I've read these boards contained a 8088 16-bit processor and 64K of RAM, and allowed either MSDOS (v1 I assume) or Northstar TurboDOS to be run.
Has anyone got an example of either type of 8/16 board, as a photo of the board would be appreciated.
Anyhow, reason for this post is that a friend has passed me a link to an eBay auction for a Northstar PCB:
http://www.ebay.co.uk/itm/NorthStar-Advantage-8088-8087-Co-Processor-PCB-/141498026720
There are 10 of these available but personally I wouldn't rush to buy one. The board has the legend:
8087 ASSY 03922
which (with quotes) prior to this page being indexed gets a big fat zero hits on Google. My hunch is that this board was developed by Northstar as an add-on to their 8/16 board, to add an 8087 co-pro (ie by unplugging the 8088 chip, plugging this board in, then plugging the 8088 back into this board).
Another possible home for this board might have been in the Northstar Dimension, a multi-user beast which featured an 80186.
My guess is this board was never launched by Northstar before their demise in 1984, so good luck if anyone goes ahead and actually buys one.
Regards,
John
