Convert 7 outstanding it.todo markers into actual passing tests now
that the chips and bus infrastructure can support them:
- 4004 LDM: ACC observed via SRC + WMP X2 bus drive
- 4004 FIM: register pair observed via SRC X2/X3 nibble drives
- 8080 hand-built loop: LXI/MVI/INR/DCR/JNZ decrements counter
- Z80 IM 2: vector table at I:00 → ISR via INT̅ low
- 8086 1 MB wrap: DS=0xFFFF + offset 0x11 lands at physical 0x00001
- 8086 ALE pulse: counts ALE rising edges per bus cycle
- 8086 AD release: external drive sticks during T2 (chip released)
- 8086 hello-world: 5 MOV BYTE [imm], imm writes to memory-mapped
"UART" at DS:0x9000; bus capture + RAM peek verify "Hello"
Plus: remove redundant 8080 CPUDIAG and Z80 ZEXDOC todos — the
actual end-to-end runs already pass in dedicated cpudiag.test.js
and zexdoc.test.js files.
Suite is now 125/126 passing, 1 todo (Busicom 141-PF demo, awaiting
firmware ROM), 0 failed.
