My video on the PDP 11/73 I recently picked up.
by Dave Shevett 13 Feb '23

13 Feb '23

Hey ya'll. I'm hoping to put together a series of videos on getting my PDP 11/73 up and running. The first video was just posted, I'm hoping folks can take a look and give me some feedback and some love on it. I've spent the last 2 months or so assembling and editing this video, and learned a lot about how to use software that is wildly unfamiliar to me. It's been fun! This is the first video of a series of getting this machine up and running - I have the next 2 videos uon the editing table, but I'm looking for feedback on this first one to help me style the next one. A like, a subscribe, and a comment goes a LONG way in Youtube land, I know folks aren't thrilled with promotional stuff, I do apologize, but this seems like a great way to spread the word on how awesome these machines are, and how exciting vintage computers can be. So, enjoy - please let me know what you think, and share it around if you think others might be interested. https://youtu.be/h6zdf0O1Qo0 -dave s. -- Dave Shevett shevett(a)pobox.com

Don't turn on the Fredon Flexwriter!
by Neil Cherry 13 Feb '23

13 Feb '23

Ian and the other gentleman working on the Fredon Flexwritere, please note: I think the diodes are wired in wrong. https://forum.vcfed.org/index.php?threads/friden-flexowriter-terminal.12417… It just dawned on me that the motor takes 100v DC and I looked at the above. The selenium diode (ah what a smell) may not work the way you think. Here's a schematic but it's hard to read. https://collections.museumsvictoria.com.au/content/media/21/535271-small.jpg http://www.bitsavers.org/pdf/friden/SP8673R2_Friden_Flexowriter_Programatic… I think the selenium diode is setup as an AC Full Wave Rectifier. We should have one of those. We should be able to figure out which wires are which. But the current wiring won't work. -- Linux Home Automation Neil Cherry kd2zrq(a)linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies KD2ZRQ

TRS-80 Model 4P - Did I Leave it at the Workshop?
by Alexander Jacocks 11 Feb '23

All, I can’t figure out what I did with my Model 4P after the last workshop. Did anyone see it? It seems an odd thing to have misplaced. Thanks! - Alex

OT - air lines in the makerspace
by Martin Flynn 11 Feb '23

11 Feb '23

Was discussion quite a while back about installing the air compressor in the furnace room (for noise control) and running an air line through the attic with drops / legs in the makerspace where required With the deployment of the de-soldering and rework stations (which run on external compressed air) we will need to revisit this, and decide on where the connections will need to be, and if any drops will be deployed in the classroom area for use during VCF workshops. Direct replies on location recommendations preferred to keep the noise level down. Martin Flynn
