Subject: Amateur project: microcode emulation
Any advice, please? (apart from MVS 3.8J with Hercules. I already have that.
But I lost the automation interface I wrote years ago)
It's been many years since I was an IBM geek. MVS/ESA and JES3, with Z/OS on
the horizon.
Is there any microcode available (functionally equiv, if not the genuine
article) that might allow me to start with basic 31-bit ESA instructions and
perhaps add others as I go?
I started an emulator that ran code for unit testing (at kips, not mips :-)
) but the good thing was that when it crashed I could slam it into reverse gear
and see how I got there.
I always wanted to update it and port it to run on an Android tablet and it
seems I have some time now :-)
Thanks in advance for any pointers or suggestions.
Rupert
