Bob Eager. Source code for port of early Essex BCPL to ICL 4130 under EMAS. 1975. by Paul McJones — last modified 2024-04-15 20:08

Bob Eager. Source code for port of early Essex BCPL to ICL 4130 under EMAS. 1975. "I ported the early Essex compiler to the NCR/Elliott 4130 in 1975. ... I spent 1973-74 at Essex, and I did a code generator for an abstract machine for my dissertation. I was working on that while Pete Gardner was developing the PDP-10 compiler ... I returned to Kent in October 1974, and ported the compiler to the 4130. It was a tight fit, and had to be overlaid. No documentation was ever written as I only used it personally."

Bob Eager. Source code for port of Cambridge PDP-11 BCPL to PDP-11 DOS. 1976. by Paul McJones — last modified 2024-04-15 20:17

Bob Eager. Source code for port of Cambridge PDP-11 BCPL to PDP-11 DOS. 1976. "For PDP-11 under DOS-11, and cross compile to standalone too. Used for our earlier terminal concentrators [for the EMAS system?]. This came from Cambridge but again I hacked it a lot. Our terminal concentrators were short on space, and loaded many initialisation overlays, kept in a DOS core image library (CIL)." [Bob Eager, Personal communication, 15 April 2024]

Bob Eager. Source code for EMAS 2900 BCPL. 197?. by Paul McJones — last modified 2024-04-15 20:25

Bob Eager. Source code for EMAS 2900 BCPL. 197?. An initial implementation ran on ICL's VME operating system, but only portions survive. The second implementation was for EMAS (Edinburgh Multi Access System), which was used at the University. Bob notes: "There is no real documentation; the code is easy to understand, even the user interface. At that time all our documentation was typed out by secretaries. " [Bob Eager, personal communication, 15 April 2024]

Ian Wilson and Bob Eager. Source code for Z80 BCPL. 198?. "Cross compiler for Zilog Z80. Originally done by Ian Wilson at Cambridge, but extensively modified by me. We used this for terminal concentrators, and space was at a premium." [Bob Eager, Personal communication, 15 April 2024]
