Measuring clock signal with an oscilloscope 🤣

Must be an easier way.... Running a program or something?
Not everyone has an oscilloscope you know. 😀

Maybe by benching your video card and then finding someone else that would use the same CPU as you did and has the VLB version of that card and compare the benchmarks

If chipset supports VLB then you can be pretty much sure that video adapter is sitting on it, would make no sense if it were otherwise, and as far as i know 86C805 used only VLB interface.

If it provides a linear framebuffer above 16M (probably if it provides a LFB at all) it must be connected through VLB or PCI. The reversal statement is not valid though.

I see... Thanks.
Can speedsys test this? Or do I need another program for dos, in order to check all this?
As for the chipset, I have these two chips: VIA-VT82C495 and VIA-VT82C481.
Following the traces, I am 50/50 on VLB or ISA. However, I have little experience in this.

I know that sometimes speedsys can bench the bandwidth of the VRAM. Maybe with some calculations you'll see if the ISA bus can handle the speed it will indicate or not. If it does, then it may be ISA. If it doesn't or that it's close to ISA's limitations then it's almost certain that it's a VL Bus card

UniVBE will tell you something about the framebuffer.

Cool... Thanks. 😀
