The output format generated by the linker for the Sym-1 target is a raw binary BIN file, which is essentially a memory image. You can convert this to a HEX file using BIN2HEX, which is a popular open-source conversion utility program. A HEX file has ASCII representations of the hexadecimal byte values of the machine-language program. So the HEX file can be transferred to the Sym-1 using the RS-232 terminal port, just as if the machine-code was entered by hand. Enter 'm 200' in the monitor and start the HEX file transfer.

As stated earlier, there are config files for 4KB and 32KB systems.

Printf requires about 1KB because it needs to know how to process all the format specifiers.
