Dad's had his second radiotherapy treatment today, and sounds quite chirpy. Apparently he'll be having a treatment every weekday from now on, which means that he has to travel from York to Leeds and back each time; thank goodness for volunteer hospital drivers! Dad says to thank you all very much for the kind thoughts that you've all expressed; he told me this evening that it means a great deal to him.
Jus is on his way back from London; predictably enough, it being the Friday of a Bank Holiday weekend, he and Jason are stuck in traffic on the M1. He should be home before midnight, though.
I'm still wrestling with DECUS magtape images and an out-of-date DECUS catalogue, and with the peculiar timing problem on the simulated KS10. I've re-MONGENed to switch mains frequency from 50Hz to 60Hz (not that the thing should be touching the mains for clocking at all!) to see whether that has any effect.
