I would agree, with Zane in that I would prefer an XP1000 @667Mhz to use every day. The apps I have maintained have migrated easily from and AS200 in 1995 to the XP1000 without issues, VMS 6.2 to 7.3. Maybe it is easier to do like kind replacement, you know all ports the same. The AS200/233 go for at time over $300 US. Once in a while an AS300 (AS250) can be found for less, depends on haw the ebay listing is worded. Dan @ Butler, PA
