Motorola MECL ICs on a PCB [myRef:251201]
These ex-equipment PCBs include MC354G s and MC356G s.
The Motorola MECL series were the 'go to' logic ICs in the 1960's and 70s for very fast response and minimal cross-talk/ susceptibility. These TO-5 package versions carried a high environmental spec.
I had several of such boards and reused the ICs in projects (easy to remove). It is likely the ICs are fine - but no guarantee. Now being offered for historic interest - or parts.
To minimise postage costs, the offer is for two boards of the above type - see photo.
