Hello Everyone, there's these old cash registers that a restaurant I work at threw out because they were old outdated technology. These registers were the Sam4s SPS2000 touch screen register, which had a lot of cool features like customizable buttons and items. Being the IT guy of the store, I've had to take home some of these registers from time to time as sometimes the software on them would get corrupt, and I'd have to manually update it from a USB with new firmware files and such. I've even restored a bricked system via tftp with files provided by the retailer.
Now that these registers are retired, I'm looking for a way to either emulate these systems and get them on a different chip (for example, getting this on a raspberry pi would be cool) or to mod it with custom code, maybe even getting it to run doom or something funny I don't know lol.
There are multiple files I have:
zImage
xlib.yaffs
sps2000
ramdisk.gz
NANDBOOT.BIN
MICOM.BIN
BOOTROM.BIN
app.yaffs
*Note that some of these files don't have extensions for some reason.
All of these files are available for download via CCR, completely legally here
All I know is that the software on the system is an ARM Based Linux distro, made to run only the sps2000 main software (which I believe is contained in the sps2000 file because I've used that file alone to update and restore the software from time to time)
Would anyone be able to help me get this either emulated or decompiled? Or have your own fun with it lol. Thank you!
