[edit] The first PLDs

I reverted 209.78.18.231 (talk • contribs)'s edits because they are possibly wrong and his other edits are POVed and possibly sneaky vandalism. The one source I found said that MMI had the first not IBM. However, I don't know enough of the topic to make clear call either way. --metta, The Sunborn 19:32, 21 May 2005 (UTC)

First: IBM but not for sale to the public, Second: Signetics FPLA's, Third: MMI PAL's(tm)
MMI PAL patent, enjoy: [1]
User:63.201.25.147
User:63.201.25.147, you were probably joking but you might want to be a bit gentler with fellow Wikipedians. I've edited-out what could be (probably incorrectly) construed as a personal attack.

[edit] PLD and PAL history

I will be adding a few items to this article from my book.

Pellerin, David; Holley, Michael (1991). Practical Design Using Programmable Logic. Prentice Hall. ISBN 0-13-723834-7. 

I release these contributions to Wikipedia to the public domain.

I worked at Data I/O Corp on programmable logic from 1981 to 1997. I was fortunate to meet and work with the most of the pioneers in this field. I was on the development team for the ABEL programming language.

Feel free to correct my grammar and spelling.

[edit] PLA / Programmable Logic Array

The article Programmable logic array reads synonymously to this article. Does it make sense to merge both articles? If not, I'd be great if someone could differentiate both article from eath other by writing some words. --Abdull 10:54, 19 February 2007 (UTC)

The Programmable Logic Array (PLA) is a design methodology that can be used in any type of device. They are popular in custom ICs and are configured with the metal layers.

A Programmable Logic Device (PLD) can be configured in the field after it is manufactured. Originally this was with fusible links or EPROM technology. They can also be configured by RAM. Signetics sold a PLA (82S100) that was a PLD. SWTPC6800 01:15, 20 February 2007 (UTC)
