Still plugging away on a Windows XP SP3
Same here. I wish I could go back to DOS.
BTW: For those of you who remember the MITS Altair 8800 kit back in the 70's, I just got my brand new kit of an 8800 'emulated remake' from Briel Computers, called the Altair 8800Micro. With a front panel with toggle switches, LED's an all. It uses an Atmega8515 to emulate the Intel 8080A (or 8080B), including the single cycle stepping for each instruction. It sells for under $225 bucks (a bargain for such a great memory). This will be a fun project for me, running 8K or 16K Altair Basic (by Bill Gates) again, and with an add on board also CP/M will be a great experience. Unfortunately I sold my old Altair 8800 PC; BIG MISTAKE!!!

When I have it working, I will try to see how Arduino could improve my new Altair 8800Micro or viceversa. This is a nice kit, good for bringing sweet memories back. 8)
