Mostly Non-Destructive HP-48 Series Keyboard Fix

[Jamieson]

Hi Tony,

Thanks for documenting this interesting take on fixing that darn keyboard flex cable to main board connection. I tried this but wasn't having any luck positioning the plastic under the flex cable. So I went the usual route and fully opened my HP48G up, removed the PCB and replaced the gummy nasty evil foam spacer under the flex cable.
