This is a great package, 1995 vintage, which I still use, under windows XP (doesn't work under win7-64).
It does all I need and has almost no bugs. It takes netlists from Orcad SDT/386 which also works great under XP, using the GDI drivers.
Was there ever a successor which retains the functionality without introducing massive bloat?
Protel 95 and Protel 98 were horrible! Protel 99 showed promise. Protel 99SE with SP6 was really good. There are about 5, maybe, bugs there, but it is pretty easy to avoid them. Most important to me, is that the schematic checks have only one bug (if you have the same pin number twice on a component, it fouls up the net generation and rules checks.) Other than that, the number of goofs it detects in multi-page schematics seems to be 100%. And, the DRC on the PCB seems to be 100%. I've done 200+ boards with it so far, up to 6 layer. If the board doesn't work, the schematic is just wrong, and no EDA tool can fix that!
If you can get a copy of Protel 99SE with SP6, I think you will find it is an extension/improvement over Protel schematic and PCB, with much the same flavor. it does have editable shortcuts and menu selections, which I have customized a bit. I no longer remember the areas that got improved/extended, but they seemed to be good and logical places to add features, not stupid fluff. I know that I asked for a number of these.
For history, Accel was the US distributor of the Protel products. Accel was getting pressure to add stuff, and rewrote the basic functionality of Protel's product in (I think, C) and pushed it out. That was Protel 95, so totally unusable it was a VERY bad joke. They had to backpedal rapidly, and eventually Protel bought them out and brought their more well-reasoned software development strategy to bear. Not sure if Protel 98 was also Accel's C-language effort, or was migrated to Delphi. Protel 99 was in Delphi, but was a relatively new program, and needed to get the bugs out, that was the 99SE version. (I think I've got this history mostly right...)
Anyway, Protel doesn't want to give away their old Protel99 program, as it will do 90+% of what Altium Designer will do.
I still run P99SE, using VirtualBox on a Linux host. Your choice of Win 2K, XP or 7.
