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 256Kb of RAM and a CGA display, using the original IBM PC Model 5160 ROM BIOS and CGA font ROM.

This PC XT configuration also includes a 10Mb hard disk with Windows 1.01 pre-installed. This particular configuration will NOT save any changes when your browser exits, since it has been pre-configured to always start Windows 1.01 in the same state.

NOTE: The Windows 1.01 mouse pointer can be controlled with your mouse, but only when your mouse is within the "CGA Display" window. This is a restriction imposed by your web browser, not PCjs.

For more control over this machine, try the Control Panel configuration, featuring the built-in PCjs Debugger, with save/restore enabled.
