Thanks. I guess what I'm wondering is whether the maximum-mode signals (S0, S1, etc) are somehow more fundamental to the 8086's operation, with the minimum-mode signals (WR, INTA, ALE etc) being derived from them solely for the be

Thanks for the blog, I read every post. I'm curious about the circuitry that drives the difference between "minimum" and "maximum" modes from the processor - another Intel pin-saving strategy. Is there basically an

It's fiddly and there's a small chance you'll break some expensive components. (I once dropped a CPU from a height of a few inches, and had to straighten out the pins with a credit card). Cable routing is a pain. I'd sti

I wanted to write an 8080 emulator for the hell of it. What target? I started in Javascript, but I ended up writing it in 8088 (MS-DOS) assembly, because it has all the same flag behavior built in. Way more fun! ZEXALL and derivatives are p

That's what mmap is for :) When a read call completes, you know you've successfully read the data from the underlying device. If you have swap disabled you know you can read and write from that memory quickly. With mmap'd dat

What is your actual goal, beyond joining the project? Is it to upstream a fix or feature you find useful and don't want to maintain as a fork? Is it to build a personal portfolio of contributions? To learn close-up about technology the

Lots of 32-bit Windows apps shipped with 16-bit installers (old versions of InstallShield and the like). When MS dropped Win16 support from x64 Windows, they built native implementations which "ran" the 16-bit installer based on t

winevdm came to mind as a rather different Windows API + CPU emulator project - it glues WinAPI thunking to MAME's x86 emulator to run Win16 apps against the Win32 API. On 32-bit x86 this is redundant, because the built-in WoW32 will d
