It did savesets, directories, searches, date matching ad nauseum. AND I have all the sources for it, if you want it. The company I worked for, CSSN, is loooong gone, and I don't think they sold a single copy! The tape format is embarrassing, but there's low level drivers at least, and it will do simple saves. Command line but mainly a command processor of it's own wit hit's own scripting language. If anyone wants it I'll suck it out of the cp/m machine and email it to you. It has some amusing features, one of which is a special-purpose disassembler/relocator; the IO port used for the Alloy card is a parameter, but the 8080 IN and OUT instructions aren't parameterized; it disasembles itself and patches all the IO instructions. Ugh.
