Online HP-45 Emulator - First calculator with a shift key

Thank you Thomas for the ROMs! I will be looking into them a bit later.

After a bit of searching, I found these simultaneous key presses trigger as if pressing a nonexistent key code 60.

Although this does switch it into timer mode, it seems buggy. It doesn't seem to work correctly. I am trying to figure out if this is an issue in the emulator or the ROM.

I have to go right now. I don't want to leave you hanging, so I added a button at the bottom to trigger the timer mode. You still have to press RCL before pressing the timer button to get it to switch modes.
