As I recall, it had a custom LSI 16-bit silicon-on-sapphire CPU. The nastiest limitation (aside from the `pushbutton' keyboards on the original machines) was that there were only 4 slots for cartridge ROMs. (You could still squeeze in five options by using a `binary tape'. We needed that a few times to run the plotter off the HP3060A system....) (HPL was weird. Remember r-variables? But at least with the A.P. ROM, you got functions and local variables.) -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7163) Domain: chris@mimsy.umd.edu Path: uunet!mimsy!chris
