I received some queries about how well PC-DITTO works. Well, I don't have an extensive (or even large) collection of MS-DOS programs, but I haven't found one that doesn't work yet. Everything is sluggish...it isn't too bad in most applications, though the programs that produce slight pauses on a real pc will seem to choke in PC-DITTO, and if you get impatient you might hit reset too soon. Overall it has the feel of a slightly overloaded time-sharing system...I've used those enough that PC-DITTO doesn't bother me. However if you are accustomed to the instant gratification of micros, PC-DITTO might get on your nerves. The worst-case performance seems to be on cpu-intensive tasks. Here's the WORST comparison I've found, for a number-crunching program compiled from QuickBasic and running on MS-DOS 2.11 on all systems: IBM PC: 1:30 Leading Edge "D": 1:02 PC-DITTO: 10:28 As I say, this is worst case, and most programs don't seem 10 times slower. However you should think twice before using a heavy-duty PC program on PC-DITTO...at least be prepared for 10:1 time increases. Overall I like the program. It is quite adequate for the sort of stuff I need to do, and obviously a lot cheaper than PC clones. My only gripe so far is that it doesn't support the ST monochrome monitor yet, though they say they are working on that. Where text is concerned I prefer using the monochrome monitor rather than the color monitor (or just about any other display, including Macintosh). Oh well. Don Rice FXDDR@ALASKA

Whether or not it is"unbearably" slow depends on the application. If the application is compute intensive (such as graphic printing calculations) it is extremely slow. However, I use Quicken 4.0 regularly and the speed is a little slow but perfectly acceptable. I have even run SuperProject Expert and Advanced Project Workbench. These are slow and if one were to use them frequently, it would drive one nuts. However, for the quick odd update, it is fine. Roy C. Gosewehr
