/* ibm1130_gui.c: IBM 1130 CPU simulator Console Display
*
* Based on the SIMH package written by Robert M Supnik
*
* (C) Copyright 2002, Brian Knittel.
* You may freely use this program, but: it offered strictly on an AS-IS, AT YOUR OWN
* RISK basis, there is no warranty of fitness for any purpose, and the rest of the

* or modifications.
*
* This is not a supported product, but I welcome bug reports and fixes.
* Mail to simh@ibm1130.org
*
* 30-Dec-05 BLK Fixed mask for IAR and SAR register display and added display
* of Arithmetic Factor, per Carl Claunch.
*
* 09-Apr-04 BLK Changed code to use stock windows cursor IDC_HAND if available
*
* 02-Dec-02 BLK Changed display, added printer and card reader icons
* Added drag and drop support for scripts and card decks
* Added support for physical card reader and printer (hides icons)
*
* 17-May-02 BLK Pulled out of ibm1130_cpu.c
