I have a Leading Edge Model D with Hercules right now. I have a Paradise EGA 350 Autoswitch card and want to find a monitor that will handle the capabilites of this card. But I have some problems. First, when I installed the card to replace my Hercules, the system would beep twice on boot-up, which is not normal. I had the card set to only work in Hercules mode, but it still beeped twice. The graphics were correct, but that sound worried me. Is there something wrong that I am doing, or is the sound something the card produces? Second, I want to find a good monitor for this card. I have looked at the Thomson, Samsung, and Princeton brands. Any comments on these, any specific models to consider, or any other ideas would be greatly appreciated. Especially anyone who has had experience with the LE and EGA, since this system seems to have a few individual quirks unlike other PCs or clones. Thanks in advance. -- "If more of us valued your ways, food and cheer above horded gold, it would be a merrier world." -Thorin, King Under the Mountain Tom Hollowell Ohio University, Athens (thollowe@ace.cs.ohiou.edu)

Well, unfortunately I can't answer as to WHY the LE Model D does this but, I too have experienced the same thing! I've experimented with AT&T's VDC750 card in my Model D and attached AT&T's 319 EGA Monitor. Upon booting the system I got the 'ol double beep! I really think it has to do with disabling LE's indigenous video controller... and not the addition of the board... > Second, I want to find a good monitor for this card.

Well I have one of the 'low end' Thompson IRGB monitors I use in CGA mode. ... and I'm NOT really pleased with its display capabilities. I have heard some good things about Samsung and Princeton though! Ken Hinds UUCP: ..!att!holin!klh

My understanding is that the two beeps from the leading edge, are just its way of informing the user that there is no monitor... <grin>, or at least, so the computer thinks. I've talked to several tech people to see if there was a way to disable it, but so far, I've gotten nowhere. ...dewitte

Actually, my hunch is that this is a result of adding the EGA card into a PC XT type BIOS machine. I put an EGA card into an IBM PC, and lo and behold! the same thing happens. My hunch is that the ROM on the EGA card takes over some vectors, and then jumps back into the BIOS ROM init code BEFORE the BIOS ROM's beep, so that things can get re-initialized properly (with the EGA ROM in the loop). This doesn't need to happen on an AT class machine, as the AT class BIOS is written with EGAs in mind. On the other hand, this is all guessing, so I could have pie in my face ...
