Hi Bill, I think that not all Serial to USB adaptors are created equal!
I have not used it for a while but I certainly used a Keyspan one with my GPS and it worked just fine I seem to remember though that some of the cheap ones did not have OSX drivers and some chipsets were reported to give problems so (unless you are into doing all the hard work yourself) I would stick to those with a proven track record with OSX (like the Keyspan ones). Of course, if the only use for the machine is to interface with the lab equipment, then using an older machine with an in-built serial port does keep things simpler. Cheers Neil -- Neil R.

It's "dead". We think this might have had something to do with a power surge then outage over Xmas. We could change to a more recent machine, but it must be capable of running OS9. Could this be a dead PRAM battery? If co, any ideas on where to get one appreciated.
