Sounds like they are using "IPA20" as a name for the three-module set that goes in the RH20 backplane (M3001, M3002, M3003). In an NIA20, this connects to a box containing an LI0072. In a CI20, it connects to a box containing multiple modules, and I don't recall the module IDs. Maybe "IPA" stands for Intelligent Peripheral Adapter or some such. It has a bit-slice processor into which the KL must load microcode. ###### Sender: eric@ruckus.brouhaha.com From: Eric Smith Newsgroups: alt.sys.pdp10 Subject: Re: NIA20 ethernet interface (Re: RH20 Interface Status) References: X-Disclaimer: Everything I write is false.

Anyone have maintenance prints for the NIA20, or specifically the M3001, M3002, M3003, and L0072 modules? ###### From: Mark Garrett Newsgroups: alt.sys.pdp10 Subject: Re: NIA20 ethernet interface (Re: RH20 Interface Status) Organization: Garetech Computer Solutions Lines: 28 Message-ID: References: Mime-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit User-Agent: Microsoft-Outlook-Express-Macintosh-Edition/5.02.2022 Date: Fri, 08 Jun 2001 00:00:42 GMT NNTP-Posting-Host: 144.132.244.163 X-Complaints-To: news@bigpond.net.au X-Trace: news-server.bigpond.net.au 991958442 144.132.244.163 (Fri, 08 Jun 2001 10:00:42 EST) NNTP-Posting-Date: Fri, 08 Jun 2001 10:00:42 EST Path: chonsp.franklin.ch!pfaff.ethz.ch!news-zh.switch.ch!news-ge.switch.ch!news.maxwell.syr.edu!intgwpad.nntp.telstra.net!news-server.bigpond.net.au!not-for-mail Xref: chonsp.franklin.ch alt.sys.pdp10:5268 in article qhr8ww40nn.fsf@ruckus.brouhaha.com, Eric Smith at eric-no-spam-for-me@brouhaha.com wrote on 08/06/2001 04:15: > Timothy Stark writes: >> Also, I found out that KLNI device.

My guess is that P == Port not Peripheral Intelligent Port Adapter ?
