Omnidata 'Omni 1' & Ericsson Portable PC

Edit: Omni-1 is a rebranded Cherry G80-0115.

I recently got these pair and thought it would be worth sharing, documenting, and seeing if anyone knows more about them than I do.

The first is an 'Omnidata' keyboard with white slider T-mount Cherry M7 (?) switches, an illuminated switch, and a pair of black slider bar mount switches for the shift key. It's in pretty rough shape, and I know nothing about it at all, or what sort of system it came from/attaches to. Appears to have space for an extra block of switches, and uses a 20 pin connector.

Spoiler:

As far as I understand, it is not possible to open these switches and replace the broken sliders, and as such, it would be nice to procure some replacement switches. Are these things rare? Keycaps are obviously another matter entirely.

The second is an Ericsson Portable PC. This has some linear spring over membrane switch, not sure what they are, but they look to be MX compatible. The switches are clipped into a metal plate, and are able to be removed from the plate, showing the membrane underneath. Caps are thick, with brown pad printed legends. The stabilisers are very good, and are smooth regardless of where the cap is pressed, but only 2u and larger caps are stabilised, leaving several 1.5/1.75u caps without stabilisers, which bind instantly on off centre presses. It uses a din5 connector, but not AT protocol. The machine itself works, but I haven't been able to get it to read a disk yet, so either I am doing something wrong (help?) or the drive is broken.
