I used a Symbolics 3600 much more memory, 4MWords IIRC. My own 3640 has 4MWord. A word was 36 bits wide. > So they were roughly comparable in memory capacity.

Sure not: you could use a 3600 with 20 MB RAM and 150 MB virtual memory.
- hga 11y agoIn the preceding generation of CADR Lisp Machines built by the MIT-AI lab, I seem to remember that half a megaword of 32 bit words was not uncommon, and at least one had 2 megawords.
- rjsw 11y agoThe CADR could address 64MB of virtual memory, a fair bit more than a Sun-2.
- hga 11y ago24 bits word addressed. The 25 bits for the LMI LAMBDA (a microcode hack that no doubt incorporated the 2 space copying GC), and 28 bits for the Symbolics 3600 family. In all cases I'm pretty sure too little ^_^. There were a lot of Moore's law skeptics back then....
