One of the most common forms of failure for Sol-20 computers is the degradation of the keyboard foams.
When these foams fail the keyboard becomes mushy and non-responsive.
These foams are really three-layer disks with a mylar contact pad on one side of a foam patch with a plastic disk attached to the other.
The only way to fix a failed keyboard that uses this technology is to replace these foam disks.
Unfortunately, nobody makes them anymore.
But, if you have a Sol keyboard (or any number of others including some from TRS-80 and Compaq) in need of help I have a set of pads ready to install. . .
Please note: some keyboards use a somewhat denser foam for some keys (Return, Space, etc.) - if you are repairing one of these please let me know and I'll swap in some of the denser disks with the package. |
