I've found a really nice PLED 128x64 display.

Its suposed to be KS0108, but i've compared the pinouts with a display that i know is KS0108, and they differ on some pins... any KS0108 expert here that can take a look at the procuct specification PDF?

Heh, ok I'll just copy things here.

Do you have more complete datasheet that would also show the commands used to control it ?

Ok I also checked Bolymin site for any information about this display and found just the same PDF there. Maybe you could email Bolymin and ask for more information about the display.

I can now see that it says "KS0108 alike" in the PDF but as it doesn't have CS lines it has to be somewhat different. But maybe the command set otherwise is same as KS0108 but would be nice to have more information about the controller used in it. Also would be nice to know more about the Vcol, Vrow and Vbt.

Would be interesting to see one of those running. Here's a link to a dutch site selling them, includes two links to techsheets, maybe they are similar to yours.

Interestingly those two look like they are the same display.

Looks like the instruction set is something like KS0108 but still the display won't work with software done for KS0108. One KS0108 can only handle a 64x64 pixel area so that's why there are two KS0108 IC's and chip selects in a 128x64 KS0108 display. But this one doesn't have any chip selects and seems to only have one controller that can handle the whole 128x64 area. This makes the code simpler to write than for KS0108 as there's no need to change the controller at the 64 pixel boundary. But this also means that KS0108 code won't work with this.

Also the datasheet is saying that the bytes are arranged horizontally in the display memory instead of vertically like with KS0108.

So seeing all these differences I'm not really sure why it's called "KS0108 alike" controller.

But there should be no problems using this in LPT port if a driver is written for this display.

Yep I would probably be the one to ask for driver support ;)

This looks like interesting display so you can expect driver support for it when I manage to get one in my hands.
