Vector Graphic

Hello all: I recently acquired a pair of Vector Graphic MZ systems - I've always had a fondness for Vectors since I had a chance to play with a hard drive equipped version in the early 90s when I was a consultant transitioning a company from the Vectors to PCs. One of the MZs worked very well, one worked not so well. To appease the wife, I sold the good one and am now looking to get the other one up and running. The issue seems to be minor, the Flashwriter II that's in the box is throwing up garbage on the "terminal" and not interpreting keystrokes properly. Anyone familiar with these puppies who might be able to give me some pointers? I've noticed a real dearth of info online for these boxes so I'll be putting a site up to start gathering info. If there's any lurkers out there playing with Vectors, send me a note, I'd love to compare notes. Thanks! Regards, Gord
