pdp-1 Assembly tools

[gray5rhino]

Hello everyone, I would like to write native assembly language programs for the PDP-1, but I can't find an assembler tool that can convert my programs into machine language files to run on the PDP-1 emulator in SIMH. I've searched online for a long time without success. My platform is Windows 11. Does anyone have such an assembler tool?

simtools has macro1, is that not sufficient? https://github.com/open-simh/simtools

I previously tried using macro1 to compile native .asm files, but it resulted in a lot of errors. Some people online mentioned that there are differences between the native PDP-1 assembly language and the Macro assembly language, which is why macro1 isn't fully compatible. That's why I'm looking for a native assembly tool.
