I am interested in emulating the earliest versions of 86-DOS. As I understand it, this would entail emulating the following: an S-100 system with an 8086 board (will be 8088 initially, until I can write a new BIU for the 8086) a 8086 support card which has two PICs, some timers, serial and...

Picked up this card complete in box. The original manuals and diagnostics diskette were still in a sealed sleeve. Scanned the box, manuals, dumped the ROM (via dumper, not debug.com) and imaged the diagnostics diskette. The manual scans are too big to attach...

Over 10 years ago, Montecarlo4Tony released a Windows 3.0 VGA driver for 8088 I wanted to see if an EGA version was possible too, but I got a bit stuck trying to duplicate the patching techniques Tony used. I am happy to report that n0p stepped in and figured everything out. With all credits...

Following in the footsteps of reenigne here with his wonderful xtserver, previously mentioned here: https://forum.vcfed.org/index.php?threads/8088-isa-bus-sniffer-device.32469/ and here: https://www.reenigne.org/blog/isa-bus-sniffer-update/ I thought I'd try my hand at bus-sniffing. I have used...

I'm happy to announce a new CPU Test Suite for the Intel 8088 CPU has been merged into Tom Harte's excellent ProcessorTests repository. They can be found at https://github.com/TomHarte/ProcessorTests/tree/main/8088 If you're unfamiliar with JSON CPU tests, I've written a short blog article...

I was briefly tempted to necro this thread as it is the top google hit for "8088 prefetch algorithm", but I will be good and post a new thread instead. I believe I have figured out a somewhat simple logic behind the 8088 prefetch algorithm, and I have written a blog post covering the details...
