Thank you for doing this. 8086 was my very first chip and I used it to run my qBasic "hello world" program on an IBM PC XT. Back then, I thought I was somewhat smart for being able to write a simple program, without giving much thought to the amazing work that went into creating these chips and related technology. I see what you're doing with reverse engineering and documenting as a very important part in preserving knowledge which is otherwise very likely to be forever lost due to IP, copyright and corporate policies. Thank you for your work. I hope you'll find strength and energy to continue.

that was an 8088, which of course had the same core as the 8086, but 8 bit data paths to get on/off chip to save system costs at the cost of some speed.
Thanks, this could be it. The clock frequency was mighty 4.77 MHz and boy was it fast when you typed "DIR" :)
Ah good, it wasn’t just me that measured the increase in performance of 286 -> 386 -> 486 with DIR then!
For me it was watching pfs:Write do spell check, which of course involved a status box showing each word as it was checked to show just how fast computers are :-)
Haha, good old times :)
