Price rise

We were shocked to find recently that we hadn't raised our prices since 2001, more than 17 years ago! I can't think of anything else that still costs what it did then, and I'm afraid we need to correct the situation. So we're applying an increase of just over 10% to most of our prices with immediate effect, except that we will honour the old prices for orders processed before the end of September 2019 and quoting the code 1909. This does NOT apply to the two new ones; they are £50 each from the start.

There is one exception to the general rise: those products that were previously £12 are reduced to £10. This means that all our current products will be priced at a multiple of £10.

Windows 10

We now have a page giving information on some possible problems with Windows 10 and/or 64-bit systems. Having said that, we have had no reports of such problems for some months now, and it seems likely that updates to Windows 10 have fixed them.

We're sorry we can not give precise instructions for fixing such problems; all the evidence points to them being problems not with the SIAM programs, but with Windows 10, particularly the 64-bit version. In spite of that, all our development and most of our testing has now switched to Windows 10.

Windows simulations

Details of available Windows simulations are on the Windows page of our Products section.

Windows installation files are big, and can generally NOT be supplied on floppy disk. Please also note that North London Line requires a display with a resolution of at least 800x600, and one larger than that is strongly recommended.

Our current plan is that all future simulations will be for Windows only. As far as we can tell, they should run on Windows 2000/XP/Vista/7/8.1/10 and later; they should run on Windows 98SE and Me, though in some cases a couple of Microsoft patches may be needed to support the now standard Windows installer and Help system. They do work on a Windows 10 tablet, though the precision of a touch screen does leave something to be desired. They also run on Linux with Wine!
