Jeff Parsons 22728fb7e9 v1.37.1: Fixed a CPU bug wherein resetting a running CPU could result in multiple runCPU() timeout handlers being created (there should never be more than one outstanding runCPU() setTimeout request); also modified the Keyboard component to use a CPU-driven timer instead of setTimeout() for keystroke injection, so that stopping/starting the CPU won't interfere with the injection process

IBM Pascal Compiler 1.00

When the IBM Pascal Compiler 1.00 was originally released in August 1981, the standard IBM PC contained at most two diskette drives (no hard drive), so compiling Pascal programs required using a "scratch disk" in drive B: and then inserting each of the three 160Kb Pascal Compiler disks into drive A: to complete the compilation and linking process. Moreover, the user was required to copy LINK.EXE from their PC-DOS 1.00 diskette (the only version of PC-DOS available at the time) to the third disk.

To make life a bit simpler (but only a bit), we've combined the contents of all three diskettes onto a 360Kb "Combined" diskette, along with LINK.EXE from PC-DOS 1.00. Here's the DiskDump command used to produce the diskette image:

diskdump --path="archive/PAS1/PAS1.EXE;PASKEY;ENTX6S.ASM;FILKQQ.INC;FILUQQ.INC;archive/PAS2/PAS2.EXE;
archive/PAS3/PASCAL;PASCAL.LIB;../../../../dos/ibm/1.00/archive/PCDOS100/LINK.EXE" --format=json --label=PASCAL100
--output=PASCAL100-DISKS.json --manifest

It's important to use the original PC-DOS linker, because not all linkers will process IBM Pascal 1.00 object files properly. Given this dependency, it's odd that IBM didn't simply distribute the PC-DOS 1.00 linker on the third IBM Pascal disk; there was certainly room for it, so it wouldn't have cost anything, and it would have reduced the risk of using a newer and potentially incompatible linker.

NOTE: We do not have copies of the three original distribution disks. However, based on information in IBM's Pascal Compiler documentation, we were able to recreate the contents of the disks. The file dates were arbitrarily selected from the August 1981 time frame.
