OT RE: 3D printer $179.99 (today ONLY) (Was: 8-Update

by jwest＠classiccmp.org

Fred wrote... In addition, how hard would it be to 3D print some parts to turn it into a PLOTTER? ------- I have not seen or done the below myself. But I have heard that there are plenty of conversion kits out there for 3d printers to do: As fred asked... https://tinyurl.com/y9d7sbwt Also... PCB creation. Some are doing pcb's by adding a small laser module to the hotend and exposing photoresist plates and then washing off all but the traces and pads. Others are mounting a conductive ink pen to the hot end and drawing the traces. Some are building thin channels for the traces, and filling them with conductive paint. Some are laser engraving or even cutting with a small (8000 mW continuous) CO2 laser, again, on the hot end. Some are casting metal parts by 3d printing molds. There are new filament materials coming out all the time. My new favorite is a wood filament. It's just wood particles in another medium, sure... but it can be sanded and will take stain. That's close enough for me! There's a reason getting a 3d printer took me away from vintage computers for a while ;) J

Off-Topic : RE: 3D printer $179.99 (Was: 8-Update

by jwest＠classiccmp.org

Fred wrote.... >> If you are seriously considering getting one, consider: >> https://www.woot.com/category/computers?ref=w_gh_cp_5 >> That offer is for 24 hours! I've had dual time-sinks the past year, a 3d printer and a high end drone :) The 3d printer I got was the creality ender 3 that is mentioned above. First, you will not find a bad review for it, all the reviews are glowing. Most reviews also say it's print quality and print-features are on-par with $1000+ printers. That is correct, and I paid $175 for mine. I love it. That being said, the ender 3 has some design deficiencies. If you buy one, plan on spending maybe $50 to $100 on upgraded options right off the bat. Once you do that - it is a better printer than many of the big names people will likely recommend. If you are wanting to get a printer and start producing production quality parts right out of the box, the ender 3 is not for you. If you are willing to tinker and upgrade just a tiny bit... you'll be really happy. J

ISO: AT&T 630 MTG Terminal Keyboard

by derschjo＠gmail.com

Hey All -- Picked up a nice AT&T 630 MTG terminal, sans keyboard as so many terminals are these days. Curious if anyone out there might have one available. You can see a picture of one here: http://bitsavers.org/pdf/att/630_mtg/630_MTG_Brochure_1987.pdf. I believe the part number to be 33401 or 33538). It's a fairly distinctive keyboard in that the arrow keys are arranged in a "plus" pattern. Thanks in advance! Josh

Any VCF Forum Mods or Admin here?

by johnhreinhardt＠thereinhardts.org

Does anyone here have any pull or contacts with the owner or moderator at the Vintage Computer Federation forums?? I've been a member there since January 2014.? In the past, I've lurked a lot, made a post here and there but have been pretty inactive. As such, my account is still moderated and post must be approved. In October I got more active, culminating with a thread asking about using a SCSI2SD card with a MicroVAX and OpenVMS V7.3 <http://www.vcfed.org/forum/showthread.php?66437-More-SCSI2D(-V6)-and-OpenVM…>. After a few waits to get post approved, I figured at some point I would get un-moderated, but no such luck.? So I wrote the Site Admin Erik <http://www.vcfed.org/forum/member.php?4-Erik> a PM and asked to be un-moderated.? He wrote back that it was done but unfortunately my next post and any others since then are still being held for approval.? That was October 27th.? They still have not been approved (nor rejected, they are in limbo as far as I know).? I PMed Erik back but according to his profile he hasn't logged in since October 26th.? After a while I sent a message to the moderators as outlined in this sticky <http://www.vcfed.org/forum/announcement.php?f=23&a=2>. No response. So I am asking here because I figure there must be some overlap and maybe someone know someone that can help Thanks. -- John H. Reinhardt

Core memory emulator using non volatile ram.

Whether that means that the way core operates is "visible" to the CPU is a debate about definitions. Put it another way - do any modern CPU's do 'read-modify-write' cycles (other than for interlocks in a multi-CPU system)? Noel

Orphan HP Alphaservers looking for a new home

by rlloken＠telus.net

Ladies and gentlemen, I have immediate access to four Alphaservers, an RA8000 raid server, and the associated fibre switches in need of a new home. There three servers that were running Tru64 Unix 5 when shut down a week ago, they are a DS15, and two ES45s. There is also a third ES45 which has not run in a decade and was kept around as a cold spare. None of the RA8000 disk will be available because the present owner is protecting his data (of course) but all of the unused spare disks are available and they will fit the internal slots in the DS15 and ES45s which may or may not have disks depending on the whim of the present owner. Lots of paper docs and Tru64 OS installation kits but no licenses. They can be had for free but shipping will most assuridly not be free. -- Richard Loken VE6BSV : "...underneath those tuques we wear, Athabasca, Alberta Canada : our heads are naked!" ** rlloken at telus.net ** : - Arthur Black
