I'm still a beginner of machine language for the c64 and have lots to learn, but I'm pretty happy with the knowledge gained since I picked this hobby up in early June 2023.

Software Used
VICE Emulator on Windows - Stock Commodore 64 with 2 1541 disk drives (No REUs, No Fast loaders etc...Just a plain boring C64)
https://vice-emu.sourceforge.io/
Turbo Macro Pro 1.2
https://style64.org/release/turbo-mac...
SpeedScript 3.2 to keep track of my notes (COMPUTE!'s GAZETTE May 1987)
64Mon (ML Monitor) from the Commodore Macro Assembler Development System
1541 Test Disk to copy the monitor to my project disk

My Self-Imposed Rules:
Writing code for the c64 using only hardware and software (sort of) that would have been available "to me" on the C64 in the mid to late 1980s. Back then, I had a C64, 4 disk drives (1541,1571, 2x 1581s), and an Aprotek Minimodem-C24 (2400bps) (I ran a BBS for a few years) before I moved on to the PC platform around 1990. I did have an Epyx Fastload cartridge, but that was about it (I never had (or known of its existence) Jiffy DOS)
