You find a lot of stuff when you are reorganizing your office #TP6 Library….
I must clean out my closets as well. I think I have similar stuff lying around.

Back in the late 80s and early 90s of last century, engineers Richard E. Berry, Cliff J. Reeves set a standard that still influences the user interfaces and user experience of today: the IBM Common User Access.
I mentioned CUA a few times before, but since an old client of mine managed to throw away their paper originals in a “we don’t need that old stuff any more as we are now all digital” frenzy, I wanted to locate some PDFs. And I promised to write more about CUA.
If anyone has printed versions of the non-PDF documents below, please donate them to aek at bitsavers.org or scanning at archive.org as they are really hard to get.
A few search queries I used:
The PDFs I think are most interesting:

This Dutch caught my eye: “Dutch telecom operator KPN has turned off the inbound internet dial-up equipment. It keeps possible to dial the number, as dial-up traffic is now handled by provider xs4all”:
KPN heeft de apparatuur van zijn inbelplatform voor internet uitgezet. Het blijft nog wel mogelijk om in te bellen via het nummer 06760-12321, maar het inbelverkeer wordt voortaan afgehandeld door provider Xs4all.

The thread is full of nostalgia on Dial-up Internet access, like:
I still have my original Courier HST Dual Standard modem from USRobotics I got around 1987. It’s looks like the second from the bottom at (image via: Do Modems Still Matter?) the picture below (one day I will make a picture when I’ve cleaned out the glass cabinet it is in; there are some more USRobotics, ZyXEL and DrayTek modems in it too).
There is a very interesting piece of USRobotics (in Russian, but Google Translate does a nice job on it): The history of the US Robotics.
I wrote mentioned the Courier HST Dual Standard before in Going to try PowerLine (next to CAT5, and having used 10Base2, 10Base-T, 100Base-TX and 1000Base-T), but never about the why, so here it is:
The Courier HST standard would train faster and at better speeds over Intercontinental lines than the Trailblazer and Hayes and later V.32bis technologies. In addition, they were also faster with firmware upgrades to support faster speeds than competing brands.
This mattered a lot to me, as initially CompuServe was only accessible by dial-up to the USA. The same for a lot of BBS and FidoNet uplinks.
For me, they weren’t any cheaper buying them (as the BBS discounts for them were not valid in Europe; I bought mine for a more than DM 1000 in Germany) but it was cheaper gaining knowledge (my motto always has been “a life long learning”).
Since the above article,
More info about modem training and standards in this 1998 article:
Everything you wanted to know about modem and fax standards and software, but were afraid to ask is covered in this great overview article by Frank Gao from Gao Research. This article discusses all the functions that go into today’s modem products, but is not tied to any particular hardware implementation.

[WayBack] While cleaning up my “attic”, I came across some old QuickReport 1.0 documents and BDE installation tips so I scanned them.
I think the first document is by this Lars Søndergaard.
The last is by Dave Robinson, then working at Amber Computer Systems Inc, but I could not find on-line activity of him If you know him, please let me know his on-line contact info.

Ons huist staat er nog maar 20 jaar. Sommige andere al veel langer…
Wilt u weten hoe uw omgeving er 50, 100 of zelfs 200 jaar geleden uitzag? Hoe het land om u heen is veranderd door verkaveling en andere ingrepen? Dat kan eenvoudig op topotijdreis.nl, de website van het Kadaster die 200 jaar topografie ontsluit.

Op de website Topotijdreis kun je inzoomen op stadsniveau en met een slider kaarten uit verschillende jaartallen met elkaar vergelijken.

Thanks Jan Wildeboer for pointing to a well written history piece by Rob Landley (Twitter @landley).
Nice #geekporn history lesson. With Linus, SUN, kissing a girl (or not), the overpriced POSIX manual and more. Enjoy. http://article.gmane.org/gmane.linux.toybox/1890 (already archived at the WayBack machine)
The piece is about SunOS, Solaris, Linux, Posix, IBM, AT&T, BSD, System V and much more.

Felipe makes a few appearances in this great _Unauthorized Access_ documentary by Annaliza Savage 1994.
Memorable moments:
Most of the “in memories” were in Dutch, but one of the few English ones says it all: [Wayback] D U T C H F E L L O W S — In memory of Felipe Rodriquez.
Karin Spaink (friend of Felipe, also suffering from MS) wrote [Wayback] Felipe Rodriguez has died.
A few of the Dutch articles that impressed me very much (some obituaries, some on the internet history in The Netherlands):
