Moving programs to the A1 is kind of tricky since there is normally only 1 expansion slot. You can either have a cassette interface in it or a CFFA-1 card. Moving between the formats can be tricky, although a CF flash card can be loaded up with ciderpress on a modern PC.
I now have my PS2/RS232 ASCII interface converter prototype working. Using a terminal program on a PC I can download programs to the A1 using the monitor commands. Once in the system, I can save to whatever type of device I have in the expansion slot.
Are there any A1 programs floating around in machine readable hex or even better, monitor command format? If not, is anyone interested in helping build a library of programs in this format?
