Great thing! Later I’ve added FLASH-based Spectrum emulator, so I could write programs for ZXS, compile it and try it directly in emulator. You wrote a code in your browser, pressed COMPILE, code went to the server, PASMO did its magic and send back my HEX (or BIN or whatever). So I wished to have “an online PASMO”.Īt first I made online editor with server-side PASMO. But over time I had a lot of assemblers, compilers and IDEs for different CPUs somewhere on my disk. It is a great state-of-the-art assembler, really perfect. When I bought Phil’s V6Z80P, I used PASMO assembler. But internet is a magic “big space for everything”. There is a lot of development tools for these computers, a tons of assemblers and utilities for any OS, from CP/M to Mac OS, DOS, Linux and Windows including. A long time ago I started to play with 8bit CPUs and old computers… again.
