Run your Sinclair QL
programs on your PC
QPC 2 is a 68000 emulator, which comes
together with a completely
re-written, highly improved integrated operating system SMSQ/E, which is QL-compatible.
This means, that you can run 99% of the existing QL programs under QPC 2 on your PC.
Demo Version - you
can see how well it works (but it does not save!)
So what exactly is QPC 2 then?
The more advanced version of QPC. Whereas QPC required your PC to run in DOS mode only
while QPC was running, QPC 2 now allows you to multitask with Windows95, 98 and NT. You do
not need to run your system down and up to start QPC 2, just doubleüclick it and it
starts. Also, the configuration of QPC 2 is MUCH easier - it is done in a configuration
window where all settings can be easily done.
Installation is much easier too, all is done automatically with an installation
or you just execute it directly from floppy disk or harddisk.
We have also reacted on the requests of many users: you can now have the QL windows
scaled! For example, if you have a graphics card or a laptop with a resolution of 1024x768
pixels, then you can decide whether you want to use the full resolution (thus giving you
1024x768 pixels for the QL ... high resolution with small fonts) or if you want the
512x256 pixels to be scaled into 1024x768 (so that you have a large, nice original QL
QPC 2 comes with the integrated operating system SMSQ/E,
which is a completely re-written but QL-compatible operating system. SMSQ/E provides a
huge number of improvements over the original QL operating system QDOS, here a short

And many other very useful improvements.
In general every well
written QL-software will work provided you have copied it from Microdrive
to floppy disk. This applies to most software written in the last 8-10
years. Even the good old Psion programs "Quill", "Abacus",
"Archive" and "Easel" work. This means, that with QPC
2 you can handle data and programs written 12 years ago!
QPC 2 omes with a manual which explains
how to install and run QPC from floppy or harddisk, and explains on approx.
40 pages the differences between an extended QL-system and SMSQ/E, i.e.
lists all the improvements in detail. It does not replace the original QL
documentation, nor does it explain the QL-extensions you should be familiar
with, e.g. Toolkit II.
