I need to do assembly programming using TASM. But TASM application is running on 16bit OS. My PC runs Windows 7 64bit OS. Is there any way to solve this problem?
You can use a virtual machine like : https://www.virtualbox.org/
, there is also VMware, Microsoft Virtual machine
you install a virtual OS on it (windows 7 32bits, XP, I was running Win98 on it to play old Prince of Persia :p) and do you work normally ;-)
