This directory contains a platform for producing CP/M-65 binaries. See:

https://github.com/davidgiven/cpm65

It should contain bindings to all the CP/M and BIOS system calls, allowing you to write arbitrary programs. Noted quirks are:

• it's up to you to decide whether to return to the CCP by exiting from main(), or reloading the CCP by performing a warm start by calling cpm_warmboot(). You do not need to worry about overwriting the CCP's zero page allocation, only the TPA.
• there's no heap support yet, but you can get at the base of program workspace via cpm_ram. For now use cpm_bios_gettpa() to find the TPA bounds.
• command parameters aren't parsed — argc and argv contain garbage. Instead, use cpm_cmdline and cpm_cmdlinelen.
• the pblock layout is going to change... lots.
