Unless it is *two* machines? ---- Agreed, all I can do is type exactly what he emailed me. He said "11/23,microvax" but then in a subsequent email said it's a "single system". His last email said he would dig the equipment out of storage over easter and let me know exact pieces/parts. What he wrote is all I know, I just want to pass the deal on to someone so whatever it winds up being is preserved. Best, J

Yes, I am not quite sure what this machine is either. [...]

from the melt.

I offer for your collective consideration my guess that it's a case of someone mistaking the label on a panel for the device inside, and the system, whatever it is, has acquired mixed labeling. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

FYI - I forgot to post; this deal has been claimed; it was passed on to the first person that replied off-list. Hopefully that person can consummate the deal and will post back to the list to let us know the real scoop on what the guy has.

The reference to RX01's also seems a little odd. Testing silicon could be a reference to IC's or the large crystals drawn from the melt. As to being used in house in the UK. Both plants (Ayr and Galway) were F,A and T plants Boards and enclosures came in already built and tested. They would plug the systems together to suit the customers configureation. If a board failed it would be sent to Hoofdorf in Holland where they had a board level repair facility. This was mainly for field service swop outs but they did handle F,A and T failures.
