Thanks for scanning this! No sign that Al has done-his-bit :-<. In the meantime is it possible to get an unlocked copy that I can OCR so that it's searchable? Should I infer that you purchased that $399 load of DEC modules? I debated, what with the J11 processor, but no FP-coprocessor and no documentation. -----Original Message----- From: cctalk [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Noel Chiappa Sent: Tuesday, February 07, 2017 5:42 PM To: cctalk at classiccmp.org Cc: jnc at mercury.lcs.mit.edu Subject: PDP-11/24 CPU later version So I was recently provided (thanks!) with a copy of the later rev of the PDP-11/24 Tech Manual (EK-11024-TM-003), which I have had scanned for a while now (waiting for a quite period on the list ;-), and is now available for upload here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/EK-11024-TM-003.pdf (Bitsavers et al, please pick this up and distribute.) So it has an Appendix D, which described the -YA later rev of the CPU card (in which a bunch of gates were replaced with a couple of custom gate arrays. Does anyone have one of these? I'd love to get a photo of one, if so. Thanks! Noel
