Ever noticed how the chimes winding lasts for so much longer than the time winding on certain old wall-clocks?
For certain chime-systems, the mechanism can be damaged if the clock passes 12 without the power left to complete the chiming. I guess an oversize chime-spring safeguards against this.
We just had this semester's robot wars at the local student hackerspace today, by the way.
Min har minuttdisplay, men ja noen ganger må man bare høre på lyden omtrent hvor den er i programmet.
I mean, konkursbo is konkursbo (to say it in Norwegian)
Hmmmm! Now that looks like s fun game to try..
Turns out I was mistaken, he's right here!

So how to know how many bytes are missing? There's a header with data length and you can see the misalignment from missing bytes in the number of feed-lines after the data. How to expect which value one missing byte had? You get that from both the source code (if you have) and the data checksum.
Using the source code tape dump to poke in the missing byte to make a program for the DEC PDP-7 complete.
It's easy to see this from the object code, due to the status bits in each word. Out of 64 possible status codes, only 9 are used. Invalid status means a byte went missing just before.
good morning ☀️☕
Cables goes where? Cable goes there!
It wasn't too difficult figuring out the front panel pinout and where it is intended to go after all.
If you want to go real hard on the ammonia salt, and less on the pepper, there's also the Djungelvrål.
Otherwise, you should try Hockeypulver if they ever get it.
I'm still surprised this managed to read 100%, despite how wrecked the disk surface got.
I would like to thank Eric Smith for writing the most esquisite Python script for emulating a proper PLL-based decoding algorithm for this sort of medium, but he's not on bsky for the time being. It's so much more robust than most other applications available.
That being said, single density FM is an incredibly robust encoding scheme, even at 250kbps which 8" disks use.
My goodness, hotel notepad paper and a tiny drop of water can actually work wonders cleaning the heads of an unhappy disk drive. (note, this is from the disk that gunked up the heads to begin with).
Felines are still alive as well!
(but maybe at a different event on the other side of the globe)
Binder, but yes.
Turns into the bestest of sludge paste.
For a certain particular reason, I would like to curse Verbatim 8" floppy disk medium pretty hard, thanks.
Expect more Nord-100 minicomputer stuff from this channel in the upcoming months.
I managed to get two similar disks for the music box, and guess what my original punching did have an error after all!
Also note the 74LS181 shenanigans. Want to compare two numbers? You thought the A=B signal activates when the result was zero (as in A-B = 0 when A and B are actually equal)?
Nope! A=B activates when B is one greater than A, because of the chip originally being intended for negative-active logic xP
The reverse engineering of the Tandberg TDV-2114 Tape Cartridge controller board is going nicely. I now have the schematics, and have thrown together a simple disassembler that is capable of making source code from the ROM dumps. And the source code kinda-sorta makes sense!
I had the full-on "burnt rubber-tire onion-like" smelling experience sporadically for half a week back when I was recovering from all of that back in 2022.
But as others have pointed out, my tastebuds used significantly longer to recallibrate. I was way too sensitive to bitter favours for months.
Then there's that window of time when a good portion of the aroma-receptors coming back may fire at random. That's some funky experience indeed.
"Snubble" is aparrently very close to some informal German slang word for "Something cute".
There's a pun in there that only kinda works in German.
The reproduction of the cluster interface is starting to come together. Only the small bits left and then I can add way too many serial ports to the old Tandberg TDV-2114.
Just flashing a few 8051-type computer chips.
Doesn't need to be fancy or anything to work, but this is what I call my "portable rig".
