oh look it's a working IBM 5154 enhanced color display, and it's on the auction site. Image
these monitors can handle 15.7KHz for the 200 line modes as well as 21.8KHz for 350 line modes. the polarity of the vertical sync signal tells the monitor which of the two modes to be in. that's about it.
there are better monitors out there, for sure. i like the original NEC Multisync because it can handle lots of different frequencies and standards, analog and digital.
because CRT monitors take up a lot of room, i try to limit how many i have.
about the only reason someone would *need* a 5154 is if they were putting together a setup that *had* to be comprised of original IBM components.
the other problem is that these monitors don't ship well; the plastic gets brittle. the seller wants over $100 to ship across the USA using the rock-bottom Fedex Ground or USPS services. there's no way this thing is arriving intact. Image
oh yeah and people are bidding it up to over $400! years ago, i thought $150 was an insane price for an old monitor like this. yet here we are. smh. Image
here's the link. maybe one of you has an issue with excess money that you are having trouble getting rid of.

just be sure to do local pickup...

I always wondered what was inside these neat 1980s radios. time to take one apart! 🧵
batteries go in here. looks like remnants of corrosion, hope it's not too damaged.
on the back there's a switch to select between local and distant (DX) stations. also a few screws.

here's a very special microcassette recorder. 🧵
in case you haven't seen these before, the cassettes are a lot smaller than a standard audio cassette.
let's have a look inside.

i've been thinking about the Surfside condo collapse. 🧵
i'm a bit hesitant to write about it, mostly because i keep thinking about the folks trapped in the rubble. it makes an engineering discussion seem a bit cold-hearted.
but engineering affects all of our lives -- which, on a daily basis, literally depend on engineers doing a good job. most people take this for granted. it's probably why a catastrophic failure like this can affect us so deeply.

a while ago i picked up this old DAT drive for a very good price. let's see if i can get it working!
it is the Mitsumi DK4-SS4001, a SCSI DAT drive.
took out a bunch of screws and now we're in! DAT drives use a helical scanning system just like an old VCR, but in miniature. the round thing in the middle is the rotating head.
