What is "D6"? Another name for Cyclomethicone?

Al, for about 2 years now, thanks to your recommendation, I've been using Cyclomethocone on floppy drives and other tapes when needed. It works extremely well, thanks for this great suggestion! I just skimmed the article, and it mentions Cyclomethicone and Jojobal Oil. Do you have any...

Thanks for this! I've updated my tension band web page with your new band option information here: http://qicreader.blogspot.com/p/drive-belts.html#Mobilion So, you ordered yours from https://us.misumi-ec.com/vona2/detail/223000860382/?ProductCode=MB-15063WA-100G ? Was this the exact...

And, I've just added a page/link to this thread on my QICReader.com website, thank you Glitch for reporting this issue. http://qicreader.blogspot.com/2023/02/long-term-problems-with-clear-qic-tape.html

Yes, but I ALSO have found that the Green 6" Plastibands work quite well, and do NOT have this shedding problem that is shown by Glitch in the first post of this thread, for the clear bands. I've had the 6" Green bands mounted now for three years on about 6 cartridges so far, and they are...

I also wish to send my sincere thank you and high gratitude to Bruce Ray and EVERYONE here (I know there are MANY) who worked hard over the last 10 years or so to bring this treasure to us...thank you, thank you, THANK YOU!!!!

Interesting side note, I DO have the original MFM hard drive from that UNIX PC that had my one Ethernet Card installed, and I have every reason to believe that the Ethernet software was intstalled and working on that UNIX PC. But, when I tried to image it, I got some errors. Perhaps I'll try...

Speaking of getting an AT&T UNIX PC apart, I created a video series on this very thing!

You indeed have a rare card there! I'm also one of the few who has one...only ONE. So, we'll have to test together. I have yet to even TRY mine yet. BUT, that said, you're in the best hands here with agentb, as he is next best other than to DoN Nichols, who only posts on the comp.sys.3b1...

Thanks everyone for the fantastic info and perspectives on this thread. It's getting quite interesting! For anyone interested, I believe I have at least 5 Data General Nova PSUs identical to Commodore Z's. All of them have problems, as expected with hardware like this aged 50+ years. I also...

Ah, thanks for linking my resources here! By a *lot* of space, you mean that I'm working with a 17-slot chassis with a double-high power supply bay, and the single-power supply bay allows for only 1/2 the room? So true. But so far, this solution has worked very well. It's all in how much you...

@shirsch I absolutely love this...excellently done!

Here is the next episode of my troubleshooting adventure 1. Fuse blown and discovery of dead Q48 (2N6051 PNP) 2. Q48 replaced by an equivalent (BDX66C) 3. The Load process starts normally (extension of the tension arms) but the Supply Reel only turns forward, tension arm inoperative, no...

My friend Dominique in Belgium is repairing his Pertec 8840A 9-Track Tape Transport (Part of his Nixdorf 620 system). On a recent visit the week of Thanksgiving, the transport went from working flawlessly to quickly degrading. Symptoms were: * Rewind not stopping, tape not loading properly *...

My memory might be playing tricks on me, but I seem to remember back in the 2014-2016 era that Al Kossow was collaborating with some original Convergent/Unisys folks on building an emulator for CTOS that runs on all modern OS, and had actually gotten it working. But my Google and vcfed.org...

Al & Chuck(G) Thanks to both of you for pointing WallyB to me in this thread. He has reached out to me by email, and we are planning on working out a way to save this piece of an NGEN System. It's true, my restoration work is bleeding over into those, which is a very interesting thing indeed...

Would anyone here happen to have access to the original early 80s binary files to to run the vintage TSC Assembler? http://bit.ly/2rLsORe (warning, takes a bit of time to load) I'm looking for the vintage software that this document refers to: TSC Floating Point Package by Technical Systems...
