APL Implementors
IPSA was heavily involved in the development of the APL language, eventually employing its inventor, Ken Iverson, in the early 1980s. Roger Moore, a company co-founder and vice-president, won the 1973 Grace Murray Hopper Award for the development of APL\360 (along with Larry Breed and Dick Lathwell). APL\360 was later greatly enhanced and extended to become SHARP APL.
Sharp employed a team of expert APL implementors and contributors in its Toronto head office location, including Ian Sharp, Roger Moore, Dick Lathwell, Brian Daly, Bob Bernecky, Leigh O. Clayton, Doug Forkes, Dave Markwick, and Peter Wooster. This group was headed by Eric B. Iverson, Ken Iverson's son. It was affectionately known as the "Zoo" and was very well respected inside and outside the firm. Initially, all APL development was done in Toronto.
Later, in the 1980s, a branch office in Palo Alto, California, managed by Paul L. Jackson, made significant contributions to APL and later J. This office included Joey Tuttle, Roland Pesch, and Eugene McDonnell.
666 BOX, written in APL, was one of the first commercial email services, known colloquially by its users as the "Sharp Mailbox." The original 666 BOX was written by Larry Breed of STSC. Leslie Goldsmith, a student hacker from Lower Canada College, joined IPSA and rewrote it for higher security. Eventually it was extended to support transferring email among multiple domains (mainframes) over the IPSANET.
