Would these potentially be the sense amp / comparators for the core? I wonder if they were anything like: https://datasheetspdf.com/pdf-file/1092342/Motorola/MC1711L/1 which might have a similar application and take +15 and -7 on L package pins 11 and 4 respectively with ground on pin 12. Being another Motorola design from what looks like a similar time period, I wonder if there could be a similarity in pinouts by some chance?
