look what I got! Image
hmm I wonder if the CMOS battery is still good Image
only one way to find out! to take this apart you just undo the two thumbscrews Image
oooh Image
dead as a doornail Image
combination SCSI card and PCI riser. I'll need to figure out an adapter cable so I can I use this with a SCSI2SD. Image
I'd like to try netbsd on it. but there are some things I have to do first: new battery, check the fan, SCSI2SD.

AAA cells: three don't quite fit. time to go smaller! Image
time for the fabled AAAA cell! Image
fits great Image
don't solder to batteries, mmmkay Image
it's booting the netbsd installer from cd-rom! Image
noice! Image
I really ought to get a better fan. these Multias have a really poor thermal design. Image
fan swap time! Image
adding a thermocouple to see how hot this gets. the lid needs to be on otherwise the airflow won't be right Image
ah crap. guess I'll have to try a network install. Image
CPU temp looks good though Image
fails even when copied over the network. looks like it is failing during the untar process. since it happens at a slightly different place every time, i suspect the SCSI2SD, or perhaps the SD card. Image

so remember these IBM PS/2 fasteners that always break? the ones in the model 50 and model 70? i have found a source for the original parts!

they're still being made by a company called Southco! southco.com/en_us_int/
they make them in all different sizes, too. Image

why are chips often so expensive? how do chip companies determine the prices of their chips? a thread... 🧵
first thing chip companies do is to figure out the COGS - cost of goods sold. this is how much it costs them to produce a chip--not counting profit or anything else.
but before we can calculate that, we need to know The Life of a Chip, start to finish!

do you watch YouTube? i have a suggestion for you... 🧵
don't give in to the tyranny of The Algorithm, and don't let it choose which videos you watch.
here's a few things you can do:
✅no autoplay
✅run adblock/script block (ad networks often run malicious javascript!)
✅subscribe to YouTubers whose content you enjoy
✅click Subscriptions, and only watch that. no home page, no trending, no "up next"
✅support them on Patreon

oh wow i hear there's a new development board from a hobby electronics company, and apparently they did their own custom chip! it even has multiple CPU cores!
can't remember what it's called but the name starts with a "p"
anyway it's cool because this has never been done before, it's totally new!

ever have a hard time finding NE558 quad timer chips? i have a solution for you!
it's a tiny circuit board with four NE555 timer chips mounted on it along with 16 tiny pins so that it can be plugged into a DIP socket.
here it is in one of my Snark Barker sound cards.
