Aw heck, why didn't you guys just say so :) Since in my day job I'm an HP reseller, I just did some checking with my HP sources. The following manual: CS/80 Instruction Set Programming Manual, part no. 5955-3442 (new part number 07957+49A-90003) is available. My cost is $24.00 each plus shipping. Does anyone want me to order some copies and ship? Jay West
