One thing I haven't got my head around yet is memory management. I previously assumed that there was no support for virtual memory at all, but I'm not sure that's the case - I've now seen a paper which discusses what might be support for it as one of the hardware modifications which were made to the #MIT machines to support #CTSS, but also suggests it wasn't actually used. In any case, presumably memory fragmentation needs to be dealt with somehow. I think I need to either look at how the emulator is implemented or do some experiments.

The second thing I've been doing is trying to figure out how ARCHIV (roughly equivalent to 'tar') works and therefore how to interpret the file format. This is the file format for most of the preserved source code (which is fortunately pretty readable without understanding the details), but the preserved files also include two versions of the utility itself. 4/n #CTSS #retrocomputing #IBM7094
