Upgrading the rat's nest
RFC-335 is titled “New Interface – IMP/360”. It's authored by Roland F. Bryan of the UCSB Computer Research Lab and dated May 1, 1972.
The technical content
A new interface between the IBM 360/75 and their local IMP has been installed. It is more “production-ready” than their previous interfaces and they would like to hear if anyone encounters issues connecting to UCSB services now that it's installed.
The early physical wiring connections between Host computers and their IMPs were all more or less hacked together and were highly specific to their individual site installation. Recall that since there is no computer networking to speak of at this time,and basically no hardware standardization between computers made by different vendors. So it's not like you can go to the store and buy commercial cables!
