Will, Once upon a time I ported the 8085 NoICE remote target to M100. You could play with that. It runs over the serial link so you can't really debug code that is for the serial port which is probably why I haven't used it in a long time (hmm... 17 years
But it might be good for your purposes. https://bitchin100.com/files/m10x/noice_mon.zip To start Assembly programming you can use an assembler. There is TASM and as8085 around. Also z88dk supports 8085 which would even let you write C code. It has some debugger as well. To get started, You might try just small bits of hand assembled poked-in or string embedded code. I find that fun. https://bitchin100.com/cloudt will even assemble individual instructions for you and give you ways to generate it as hex, decimal, character codes, etc. Pop it up with the C0DE button and type in an assembly instruction. It will show the hex codes immediately. Click a button to generate text into the keyboard buffer (you'll want to be at the BASIC prompt or in TEXT when you click so the text has somewhere to go). There is a complete 8085 reference sheet in the Bitchin100 wiki https://bitchin100.com/wiki/index.php?title=8085_Reference The books you want are Inside the Model 100 by Carl Oppedahl and Hidden Powers of the TRS-80 Model 100 by Christopher L. Morgan. And the wiki -- John.
