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.
- fsckboy 6y agothat 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.
- dt3ft 6y agoThanks, this could be it. The clock frequency was mighty 4.77 MHz and boy was it fast when you typed "DIR" :)
- robin_reala 6y agoAh good, it wasn’t just me that measured the increase in performance of 286 -> 386 -> 486 with DIR then!
