Jeff Parsons 0f06c3f039 The 5170 AT hard disk controller is limping along now, so I'm getting ready for a 1.15.4 release 
Some other interesting bugs were fixed along the way:
the Video component incorrectly assumed that masking a negative number with 0x80000000 would yield 0x80000000 (it actually yields -0x80000000, thank you JavaScript);
the ChipSet component provides a new addCMOSMemory() interface that RAM objects can use to bump the CMOS total to match the actual total;
the CPU properly implements INSW and OUTSW instructions now (kind of important for the AT hard disk controller)

IBM PC

The above simulation is configured for a clock speed of 4.77Mhz, with 64Kb of RAM and a CGA display, using the original IBM PC Model 5150 ROM BIOS and CGA font ROM. This configuration also includes a predefined state, with PC-DOS 1.0 already booted and DONKEY.BAS ready to run.

And now that PCjs automatically saves all your changes (subject to the limits of your browser's local storage), you can even close the browser in the middle of a game of DONKEY, and the next time you load this page, your progress (and the donkey) will be perfectly restored.

For more control over this machine, try the Control Panel configuration, featuring the built-in PCjs Debugger.
