Three decommissioned lighters - old barges that were used to transport coal and other industrial materials - have been sunk in the Blackwater Estuary, between Maldon and West Mersea in Essex.
1. I wrote a markdown file with the specification of what I wanted to do. Just English, high level ideas about the scope of the Z80 emulator to implement. I said things like: it should execute a whole instruction at a time, not a single clock step, since this emulator must be runnable on things like an RP2350 or similarly limited hardware. The emulator should correctly track the clock cycles elapsed (and I specified we could use this feature later in order to implement the ZX Spectrum contention with ULA during memory accesses), provide memory access callbacks, and should emulate all the known official and unofficial instructions of the Z80.

How often does the "slow path" actually trigger? With 32 TLB entries covering 128 KB, Intel claimed a 98% hit rate for typical workloads of the era. That sounds impressive, but a 2% miss rate means a page walk every 50 memory accesses -- still quite frequent. So the 386 overlaps page walks with normal instruction execution wherever possible. A dedicated hardware state machine performs each walk:
，这一点在WPS官方版本下载中也有详细论述
