Does anyone recognise these boards please

[Kevin Parker]

Be most grateful if anyone can advise here please. Rescued a TRS-80 MC10 from deceased estate recently - it was headed for the bin
but got saved. 

The original owner was a bit of an electronics hobbyist and his brother-in-law tossed these boards in with the bundle I grabbed.
