==================================================
8-BIT / MOS   Commodore 64 & Commodore Plus/4: MOS 6502/7501 architecture, Commodore BASIC v2/v3.5, 1541 5.25" floppy drives, tape azimuth tuning, and raw PEEK & POKE memory manipulation.
DOS PLATFORM  MS-DOS 5.0 to 6.22: Squeezing every byte out of the 640KB conventional memory barrier (HIMEM.SYS, EMM386, UMBs, MemMaker), multi-config boot menus, Norton Commander, and batch automation.
EARLY GUI/NET Windows 3.1 & Windows 3.11 for Workgroups: 16-bit cooperative multitasking, Win32s subsystem, IPX/SPX and NetBEUI local networking, dial-up networking, later TCP/IP over PPP.

CORE ETHOS    Modern hypervisors and cloud platforms feel less like magic when you started by managing memory maps, IRQ conflicts, boot loaders, and hardware limitations by hand.
              There is no cloud, it's just someone else's computer.
