Ok, I have several of these POS register displays. I am using one of them without the USB board on my robot project but would like to know if there is software available to run a display like this from my PC through USB?
The USB board contains an intel N80930AD4 and an AM29F010B among other smaller chips.
None of the high voltage pins go to the LCd board so I could replace that cord with a normal USB connector and it should work fine...just need software to control it.




Thanks!

I suspect you would have to write your own Windows USB driver for it!, a project which is extremely complex, and may be impossible without full information on the display (which I'm presuming IBM wouldn't give you?).

hvan't asked, but I doubt they would. I guess I'd have to interpret datasheets and figure out how it's wired up but even then, I've never written a device driver before. Oh well.

Plus the Intel chip is probably a pre-programmed micro?, so you've no real idea what it does, and (obviously) a datasheet wouldn't be available!.

Well, I decided to go ahead and alter the cable, just to see if my computer would recognize it. Plugged it in and it saw it, installed it, and told me it was ready to use. The display reads, "OK"
Now that I know it works, I just need to figure out how to send text to it. Any ideas?

Ok, so below is what I get when I plug it in to USB. I also downloaded a program called HHD USB Monitor. It looks at the USB device and each interaction between the computer and the device.
I don't have any experience with USB and have read this through the best I can but maybe someone else who has used this software can tell me if I've missed any information that might be important in finding software that would allow this to run.

If all else fails, I may go with the parallel port interface and ditch the USB board...though i'd really like to be able to use the ready made USB as I have plenty USB and only one parallel port.

It looks like you have a USB HID device with two packet types. I recognize the ending C0. Can't recognize anything else in those blocks (the ones that end with C0) off the top of my head.
