- Summary: BYTE ran a series of articles in 1983
- Keywords: NAPLPS
-
- In article <oeL6PB4w164w@uuisis.isis.org>, Michael Dillon asked where
- to find information on NAPLPS, as used in Prodigy, ALEX, and Telidon.
-
- Back in 1983, BYTE magazine ran a series of four articles about NAPLPS,
- the "North American Presentation-Level Protocol Syntax", a protocol
- developed for encoding videotext graphics. The first article was
-
- "NAPLPS: A New Standard for Text and Graphics,
- Part 1: Introduction, History, and Structure"
- by Jim Fleming and William Frezza. BYTE,
- volume 8, number 2, February 1983, pp. 203-254.
-
- The articles presented a large amount of detail about how NAPLPS works
- and how it may be used; the series of articles continued in the March,
- April, and May 1983 issues of BYTE.
-
- NAPLPS, pronounced like "nap-lips", fits in at approximately level 6
- of the OSI (Open Systems Interconnection) reference model, but it
- bears only slight resemblance to the ASN.1 (Abstract Syntax Notation
- 1) and BER (Basic Encoding Rules) that constitute the official OSI
- level 6. NAPLPS defines a methodology of representing graphics
- primitives within a 7- or 8-bit code set built around the model of
- ASCII. (If you are fully OSIfied, you may prefer to say "built around
- the model of International Alphabet number 5".)
-
- (Devotees of computer-industry history will note that the cover of
- the February 1983 issue of BYTE featured a newly announced computer
- system which promised to change the way people used computers--the
- Apple Lisa. And I happen to think that the editorial on page 6 was
- well written. :-)
