Will try this as well, but again, can't tell result 'till morning. Maybe I'll try OFF IO first to see the effect, then move on to this if it doesn't. Doing both may correct it, but I'd hate not knowing why...

Thanks Joseph.

First, there is no difference in startup time between versions 1BBBB and 2CDCC.

The most probable cause of a delayed startup is indeed the DISPLAY setting. Try DISPLAY IS * first.
If it doesn't help, try RESET HPIL. The HP-IL module could be in a strange state.

Then, check your installed LEX files and option ROM, and remove unknown LEX files that could do something at startup.

Finally, check your STARTUP setting, or clear it with STARTUP "" (with JPC ROM, you can check it with STARTUP$).
