No jumpers or other variables will make it so. As far as I know >your 3/200 memory board will only work in 3/200's and will not work in >3/400 or 4/300 either. I have just tried the combinations below: 3/480, 3/4xx memory Works (of course) 3/280, 3/2xx memory Works (of course) 3/480, 3/2xx memory Works 3/280, 3/4xx memory Works 3/480, Clearpoint 16M for 3/280 Works, but only if it is not the first board in the system. If 1st, it fails the forced ECC interrupt test. Allan Doyle adoyle@bbn.com BBN Systems and Technologies Corporation (617) 873-3398 70 Fawcett Street, Cambridge, MA 02138
