Re: SBC in a regular computer...

You are not going to fry anything, as long as the SBC uses all ISA pins according to the standard. It will simply not work, as the SBC and the motherboard will conflict, preventing the system from coming up at all.

The last device with termination must be connected to the very end of the cable. It's a bus and you can not leave the wires going on after termination.

Now, in 1024x768, there's no more image, black screen and I have to hard reboot. You are saying "now". Are the cards still both working correctly when using each single?

The system won't see whether a RAM chip is CMOS or NMOS, so yes, you can mix them. But NMOS should really be avoided these days, even in vintage hardware.

It's not an image then. xcopy should work as long as you add parameters for copying hidden files and sub-folders. Note however that the system files can not be just copied over, so you won't get a bootable partition by just copying the files back. You need to boot from a floppy with exactly the same …

I have an OS image on a CDROM disk. What is the best way to copy these contents to a hard drive ? What type of image? How did you create it? Ideally, you use the same software to restore it.

I'm still pretty sure that neither the cable nor a second VGA card is needed. Probably for a dual-monitor configuration, maybe. That edge connector is the same as the header below, btw, so you could use either of them. Anyway, that card has everything on it to act stand-alone. Besides, the feature …

This card should work as is, it's a stand-alone VGA card with 2d hardware acceleration.

No such thing as FDD "correctly detected during boot" - most BIOSes won't comply if FDD is broken, different than configured or not connected at all. Of couse there is. And most BIOSes (all I ever saw actually) will complain if the floppy drive is not connected or set to the wrong type. It's part …

Alkaline solution from a battery can spit across quite badly. I've seen (and had) systems where stuff on the other end of the case had rotten away, even though there was no direct path taken by the alkaline solution to that spot. Also, even desktop cases are often stored upright, as they take less …

just one question though, if I try to use 2 ISA sound cards (this one is set to 220, IRQ 5) it locks up at post. The other card is an Aztech from a Packard Bell. That card is PnP and has no jumpers on the board. Go into the PnP configuration in the BIOS and make sure the ressources used by the …
