Pictures of an KDJ11-BF (was KDF) ??

The final letter denotes the board revision, unlike KDF11-B where it denotes the firmware revision. Technically at least, it has nothing to do with PMI capability; all KDJ11-B have that. Originally, the -BF boards sold as 11/83 (etc) used PMI memory and were all 18MHz, while the boards (mostly -BB and -BC) sold in 11/73 systems (non-PMI QBus memory) were only 15MHz, but either flavour will work either way. Early 11/73 boards won't work with an FPJ11 (-BB should be OK). You mentioned the EPROM numbers in a later post. 23-395E5 and 23-396E5 aren't ones I'd heard of, though, but likely are merely later ones than I knew of (or have copies of). I knew of V6.0, V7.0, and V8.0. Fancy dumping the contents to a couple of files? See http://www.dunnington.u-net.com/public/DECROMs for more. -- Pete Peter Turnbull Network Manager University of York
