While digging through a box of old VAX CompacTapes I found these two tapes MICRO-VAX HOST-TAPE: VAX/VMS Backup File: PSDIST.BCK Rev.: A2.V01 PS300 VAX HOST COMPACTAPE Format: VAX/VMS Backup Format Files: USER.BCK, TOOLS.BCK, DEMOS.BCK Part Number: 904003-040 Rev. Level: Illegible I do not know whether these two tapes still contain what they say they do, but if there's interest I can dig out my external TK50 and make an attempt to read them. The PS300 looks like a pretty interesting system. - Josh
