The PPC-1 and the PPC-2 were meant to be a portable and cheaper alternative towards the IBM PC. The Corona PPC is internally almost identical to the IBM: they both use the same 8088 processor, they both use the same keyboard, they both have the same amount of floppy drives for the same sort of floppy disks, the PPC is compatible with software for the IBM PC and the PPC had four slots which are fully compatible with the IBM PC.

Every Corona PPC has at least 128 Kb memory, at least one 360 Kb floppy disk drive, a communications port, a printer port and a 9" monitor. The interfaces for these peripherals are built into the system, making it possible for the four expansion slots to be used for other purposes. Corona also sold an optional 10 Mb hard disk. The PPC-2 was a bit more advanced compared to the PPC-1, due to the fact that the PPC-2 had two drives and had a memory capacity of 256 Kb.

There existed another PPC model on the market: the Corona PPC-XT. The PPC-XT could read double-sided floppy disk with a Winchester hard disk of 360 Kb and had a memory capacity of 256 Kb. The PPC-XT was also compatible with the Corona 10 Mb hard disk.
