Another good one. I'll check for references to SYMBOL in this book when I get home tonight. I believe TCMHC only has the CPU. Its the box on display between the PDP10 and the Meiko supercomputer. BTW, David Ditzel of Transmeta worked on SYMBOL (at Iowa?) and recently rediscovered the machine on display during a recent visit. When I was in college in the 75-79 timeframe HLL architectures were the subject of considerable interest and research (and I believe this was the case for the previous 20 years). I was originally drawn to working at HP by the work they had done providing microcode support for an incremental APL compiler on the HP3000 (which was the subject of a lawsuit HP lost before withdrawing the product, but that's another thread). I thought it was a fascinating field, but the tidal wave of RISC architectures in the early-80s I think pretty much killed off HLL architectures (which I believe was the right thing).
