<YEs, but you need to keep quite a bit of stuff in memory. I think perhap <32K of data memory. I'd like to see anybody fit all of TeX82 into the <other 32K that's common on a CP/M system. Overlays and other sectioning techniques. Also a good portion 32k data area can be farmed to disk files. 64k space can be tough but people ahve done bigger things in smaller machines. Allison
