|Comment||The PC-E500 is rather fast and its graphical
display makes entering BASIC programs pretty comfortable.
It was later replaced by the PC-E500S.
It is rather tricky to find out about the available memory. Use FRE0 and FRE1 to get the free space for programs and variables. Use INIT "E:" to clear all the files from the RAM disk, then DSKF "E:" to see the free space on the RAM disk. For the PC-E500S FRE0 returns 52886 and DSKF "E:" returns 201216, in total 254102 bytes. So 8042 bytes are used internally. Files can hold programs or data.
The PC-E500 comes with a sliding cover lid that can be put on the back of the unit while working with it. The PC-E500S is equipped with a hinged cover that can be removed.
The keyboard layouts are identical.
