spankmeister posted:check for Rifa caps in the power supply, they tend to go bang and let the magic smoke out. thanks for the heads up. i have a feeling refurbishing this thing is going to wind up costing me some time. still, it's been sitting for 20 years and it's 36 years old, so the fact that i could get anything out of it with an hour of loving around is surprising

iirc failed rifa filters can just be desoldered and the power supply will just start working again. they're there for reducing RF noise on the mains, so as long as your AC isn't total poo poo it'll be fine

i've been working on a text viewer. it's web-based, multithreaded (web workers), streaming (a wasm xml parser) but my favourite bit is the minimap scrollbar thing https://i.imgur.com/xtZmrXw.mp4 have a play yourself https://bigtxt.org/

Digital text viewing takes away a physical sense of "where" I am in the content, and this re-introduces it nicely. I noticed CTRL-F to search doesn't work, why is that?

The Eyes Have It posted:I noticed CTRL-F to search doesn't work, why is that?  those performance improvements are necessary but so is search so I'll have to make my own search index. argh. that's annoying but it comes with some benefits like how it could be better than native search, with proper full text searching (stemming etc.), and I guess it could display search results in the minimap

N.Z.'s Champion posted:for performance reasons it only renders the text that's visible so unfortunately any offscreen text just isn't there for the browser to CTRL-F search. Thanks for spelling it out, I get it. It looks so much like just a big screen of text that I seamlessly expected it to work like one, hah

infernal machines posted:i had to replace the two 1/2AA 3v cells on the board as they were long dead, but thankfully not leaking. in theory one of them is required for power on. it still didn't power on after replacing them, but i'm guessing one of the electrolytic caps in the power circuit is also too far gone. almost certainly, and all the others too probably. better get them off before they destroy traces! same with the ones in the power supply an unaccelerated 8•24 video card should be inexpensive and give 1152×870 at 8bpp on most multisync LCDs also you’ll need a 68851 PMMU to run A/UX (or NetBSD, or MacMach, or to use VM on System 7) if there’s not already one in there

like did it just expire? there's a 2 year grace period where you cant operate till you renew, but you can keep your call and dont have to retake

as far as i'm aware you can renew them for another 10 years at any time right up before two (three?) months before it expires, at which point you can't do poo poo about it until it actually expires

i only got the technician one because i had no equipment or space; even now the best i have is a rabbit ears antenna in my apartment's window, which is good enough to get the local weather but not much else i wonder if i still have my ham-it-up upconverter somewhere

apparently you can do exams at certain industry canada offices so that might be a good option I'll probably go for the advanced (extra class equivalent) one. the basic class here covers both technician and general equivalent; if you get 80% or better on the exam you get the general equivalent, if you get any passing grade less than 80% you get a technician equivalent. I can't jam a big fuckoff antenna on my apartment balcony or anything but might as well try to remember my "how to build a radio receiver" electronics poo poo and go for broke anyways
