Some time later (mid 90s) I loaned it to a friend for some contract work at <a likely-bankrupt public utility in San Francisco>. I drove it up there and delivered it on a cart. The stars, however, did not align for getting it back to me the same way so they shipped it to me where I worked. There was some damage to the plastic front cover and control panel mounts. I was able to repair or work around most of it, and the unit still works fine to this day. (Well, the plastic take-up reel is loose...) Pretty much everything I have that could go in a rack I fetched myself rather than having it shipped to me. While one can't always do that, I recently carted home an HP 3455A multimeter from Los Angeles, some 400 miles. I was already in the area, otherwise I don't think I'd've made the round trip just for it. > Based on the service manual, it appears that option 800 requires: > * buffer PCA 07980-6xx14 (512K) or 07980-6xx34 (1M) > * read/write/formatter PCA 07980-6xx31 > Mine has the 800 bpi option.
