If you needed any services like IO, file-handling, etc, you were on your own. Also, the development environment was un-friendly and difficult. I understand that things have changed now, but at the time I couldn't afford $3k for something that was so incomplete. I returned their sampler, and asked them to contact me when this product has matured, but I haven't heard one word in 2 years. We DO have pSOS for 68k processors, and the guys that use it seem to like it well enough. I believe that Software Components' experience began with, and concentrated on Motorola processors. I don't know if it's possible to develop applications on your target with pSOS-68k -- last I knew, you had to assemble/compile on a VAX or PC or something, and then download to your target. Software Components has NOT kept in touch with our people using their product, and we are disappointed and are dropping use of it. In my search for a RTOS for PC's I stopped looking after I found QNX by Quantum Software Systems. It is a real-time, multi-tasking, multi- user, networking OS that is fast, compact and reliable. It runs on any PC family machine, from an XT to PS/2. It runs in Protected-mode (has for more than 2 years) and has a utility called RUNDOS that permits many, (but not all) DOS applications to run without leaving QNX. I am running NCSA Telnet that way now, for example. Contact me if you'd like more info. *** Usual disclaimers apply.
