P112 question - what can you run that uses 1MB of RAM?

Hi, All, I'm not joining in the kickstarter because I already have a P112 I purchased as a bare PCB and loose SMD parts in the previous round. I

just uncovered it last night moving some things around and started tossing build-parts into a bin to put it together. I do happen to have a couple of 32-pin JEDEC 512K SRAMs (originally for an SBC6120 RAM disk PCB that got destroyed in the mail), so I _can_ fully populate it, but it got me wondering... what CP/M software is out there (except maybe a RAM disk) that can *use* 1MB? I have a bit of experience with 48K-64K CP/M machines (mostly Kaypro, but some others), because back when I was using it, that was how much memory 8-bitters had. I didn't mess with them much after 1985, so if there was still any development on that platform, I didn't see it. So why *does* the P112 have 1MB of RAM? What's the space over 64K good for?
