Line Printer is generating many extra line feeds (such as in the middle of assemblies).

C. Farrell

18:32 LPT also fails to print occasional lines, and varies format of those it prints. It shall henceforth be termed RPG = Random Print Generator

The III displays 0, 1, 4, 5 were switched on over the weekend, that keeps the [kathoole?] filaments heated. Is this ok? M.H.H.

IT BETTER BE OK. D.P.

Had a burst of parity errors from AMPEX CORE

[printout with annotations]

Restarted at 140, zeroed ampex core. for 30 min, no errors. Ran BLTST for 30 min in ampex core, no errors. The programs running in Ampex core were loaded by loader, which clears fore first and [?]SP which initilizes core, so the errors were not left over from the past. Apparently something hits in bursts.

SRR

--> I have a suspicion that there is a mechanical difficulty.
