Elmer B. Shapiro Stanford Research Institute 24 March 1969

2a From AT&T and/or BBN need dimensional, power and cabling specifications 2b Need to establish SRI desired alternate locations so as to determine maximum telco cable lengths 2c Need to establish location and drops on voice coordination circuits 2d Need circuit information on voice drops for tie to intercom system 2e 2f 3 Need to order and install a.c. power (coordinate with 4b) See 16

Design and construct host-Imp interface 9/1/69 3a 3b 3c 3d 3e 3f Need specifications from BBN Develop trial design Review with system programmers Establish final design Build and design hardware Debug trial software with hardware loop test

Debug host-Imp interface 10/1/69 5a 5b Get debug specifiations and procedures from BBN Write programs to debug with BBN 5b1 5b2 5b3 Transfers of test messages Test procedures for crash and recovery Check message fill and stripping procedures

5c Try own transfer tests 5c1 5c2 5c3 5d 6 Verify transfers to Imp Verify transfers from Imp Verify transfers looped with Imp

Work out Imp reload and restart procedures

Various combinations

Login, logout, in and out of subsystems Handling of error messages, crashes, recoveries Establish message formats Establish protocols File storage and retrieval Need user's guides for each site Need to establish usage schedules Need to set user names Design and build comm exec or its equivalent

Run simple typewriter systems 10a 10b 10c Same as 9c - 9g How define when in half or full duplex mode How to set "break" characters
