Very cool, EDTASM+ was loads of fun bitd! You will have an awesome time learning with it - the EDTASM+ cart works with tape or ipod for loading/saving which is also convenient.
It will only take advantage of 32k, but that's plenty of room to assemble pretty big Machine Language programs without linking.
What kind of Assembly are you writing James? 32 columns is perfect imo - big easy to see mnemonics and operands with room even for comments!
Only taking advantage of 32K = source code + symbol table + binary. So not 32K of code.
32 columns is perfect?
The MC-10 version of my 64 column text code (RG6 graphics mode) is 1010 lines long, and with comments is over 120 characters wide at times.
The source file is 34K and that's with macros to shorten it. (FWIW, the Z80 version source is about 39K on disk, and the current 6502 version is 41K)
I'm using Notepad++ and can view around 150 columns of text with comments, opcodes, and keywords in different colors.
I can also compare different versions side by side and have many source files in the editor at once.
Plus, it only takes a couple seconds to assemble my code on my laptop.
When I get around to a 6809 CoCo port, the source will probably shrink to just over 30K and I highly doubt EDTASM+ could assemble it even if I don't use macros.
That's just a demo that prints the font over and over.
The final project will probably have multiple assembly language pieces that large designed to link to C, something which EDTASM+ is totally unsuitable for.
If you want to learn assembly, EDTASM+ is fine. If you want to start a major project, it's just going to slow you down.
I'm not saying you can't write a decent game or other program in it, but it will limit what you can do.
