Self decapping IC

New challenge. Reading, decoding sector layout and then running the software in a modern emulator. Help appreciated :) #floppy #floppyarchaeology #retrocomputing #cpm #vintagecomputer

And finally all updates have been installed. It's probably worth backing up the disk now.

Maybe we are done with updates. Let's wait and see if the load settles down

3 hours, half way in, Win7 update on Fujitsu tablet (Atom + SSD) from 2011. Patience...

I'm playing with #greaseweazle and a bunch of random floppies at flux level. This is a MF/2HD (1.44 MB). All other disks in the box are in DOS format and show up as expected. This one has handwritten label "Install 1 HD". Not sure what's going on here! @bolex70 maybe? :)

Who can hear me screaming 😱😱😱😱? You can join me too🤣

While learning how to recover data from a formatted floppy disk with greaseweazle + testdisk + photorec, I spotted this email. I wonder if they realized they missed by one minute a once-per-century peculiar timestamp. :-)

Might have been faster to do a clean install. But all drivers are already installed. Lazy me.

I am cleaning a WinXP laptop that slept in a drawer for 13 yrs. Folders in Explorer are black or blue. OMG! Compressed folders! #retrocomputing

@BoscoMac Not visible here (I1) right now. Is it decodeable? Does it respect TX rounds? Looks like someone with a strong 100 Hz hum

Since yesterday, I've been observing a jammer on the 15m band in the FT8 range. It's simulating FT8 signals in parallel, all with the same bits. Can anyone confirm this? #ft8 #hamradio

Found this printout in my teenage room: Virus characteristics list V74. By McAfee 1991. I don't remember the origin, and I never owned a dot matrix printer either. I will try to look online for the digital file. The world was simpler back then. #virus #mcafee #retrocomputing

"I am done with this retro laptop (totally offline) I used as USB charger, let's go home." Doh! #windowsupdate

And it's that day when you get to use the RCA-RCA cable you saved for 20ish years and the RCA-BNC adapter :)

Receiving weather report on #HF #RTTY with time-correct equipment: IC706, Telereader CWR-800, monochrome CCTV monitor :-)

@toybuilder The fastest way to use them I can think of, is to build R-2R ladder DACs. Three resistors per bit and a lot of soldering :-) It doubles as a vision test, too!

What are the odds that I'd finish using up these 10K resistors before my kids inherit them?

If it was supposed to work without a heatsink, why put it in the first place? The chip beneath has a thermal pad. I am not sure I want to fix this. I could keep the machine as an offline display. Any thoughts? Have you seen similar failures?

I wanted to take a server to a bar^H^H^H public event to show how they are/were made to those ppl whose computing is all done in the cloud. To make sure the chosen one was designed for quick maintenance, first thing I open it. I picked an #HP #Proliant DL140 G2 Continues...

It looks like one of the holders has come off. Nevermind, I opened a twin DL140G2: same failure! And a third specimen too! When I picked the fourth (and last in my stock) I heard something small jumping inside the unit. Of course the heatsink was lifted. Continues...
