So, I bought a copy of the FP11-A Technical Manual (EK-FP11A-TM), but when it got here, it was the 'Preliminary' version (-PRE), with type-written text, some of the figures are hand-drawn, etc. This manual does not seem to be generally available online, although at one point a copy was available for download briefly; although it's not the greatest scan job, I have put it up here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/EK-FP11A-TM-002.pdf So, is it worth my scanning the -PRE version, or should I just punt, and we'll go with that scan of the -002?
