New (free) 50th Anniversary Simulator - HP-35, HP-45, HP-80

[Rob W]

Hi Sarah,

I've been exploring your HP-1973 simulator and I'm blown away! I love how you've presented all the information on a single screen. I've been playing with the different Update modes; single stepping and live execution are really fun. The ROM Map is cool touch - pressing a trig key in Live mode and watching it jump between the three ROMs is just terrific.

I was going to say that I wish I had had your simulator when I was developing my HP-35 replica from the '569 patent but, as I'm sure you know, it's more fun to work it out yourself. I can see that you, like me, have been smitten by the brilliance of the HP designers and your simulator is a worthy tribute to them.

Well done!
