My first job in Maynard was project lead for DECnet-11D & DECnet-IAS (Phase II). It was basically the same source code for both, just
separate builds since they were released as separate distributions. Later versions consolidated the releases into a single kit.
The V3.4A tapes will claim to be running IAS but, if you select the “Real-Time” options during sysgen you’ll get the familiar MCR> prompt:
1920K (word) IAS Version 3.4A Baselevel 3414
SAV -- Partition GEN expanded by 57472 words
Class =File 11
MOUNT -- DB0 ** Mount Complete **
Date and time, please?
IIRC, IAS development in Reading was done mostly on an 11/45. The 2.0 SPD confirms that IAS was supported on 11/45, 55 and 60 but
only with 2 active terminals.
