| zxmpi | on this day in 1955 eniac computer was retired | 12:08 |
|---|---|---|
| penguin42 | I wonder what it's parts were reused in | 12:17 |
| zxmpi | probably a lot, a *LOT* of valve radios :-P | 12:17 |
| daftykins | heh some seems to survive - https://en.wikipedia.org/wiki/ENIAC#/media/File:ENIAC_Penn1.jpg | 12:23 |
| daftykins | also, a happy weekend \o solid rain here, ideal time to start picking through the 3 new systems that have joined me at dafty HQ | 12:24 |
| daftykins | a clients secretary's little cute Dell Latitude 3330 seems to be POSTing on less than 1 in 10 attempts | 12:25 |
| zxmpi | power supply or short? | 12:25 |
| daftykins | well i fiddled around stripping it down, unplugging parts... fires up once in a while and behaves like normal, otherwise the power LED just lights white as is normal and no image ever pops up | 12:26 |
| daftykins | kinda tempted by an entire replacement board set from ebay for £40... but the thing is, this is 3rd gen intel Core... an entire newer generation ThinkPad can be had for not much more | 12:27 |
| zxmpi | not even a beep? | 12:42 |
| daftykins | nope codes are allegedly conveyed by LEDs on this one, but none show up | 12:44 |
| daftykins | i did feel a MOSFET on the board that seemed a bit toasty, could be within norms though | 12:44 |
| zxmpi | i'd remove everything incuding ram and see if i can get anything consistently out of it | 12:45 |
| daftykins | that's what i started with :D pretty old hat in the hardware diagnosis circles, me - at least relative to my younger age of course :P | 12:45 |
| daftykins | weirdly there's a stripped head screw far down in it though, so i'll have to get creative with a dremel clone to sort that out | 12:46 |
| zxmpi | sounds like someone has been there before you | 12:46 |
| daftykins | it's a bit weird 'cause i'm the only one that would work on this stuff, but i'm not in the habit of ruining screws... so i don't get it | 12:47 |
| zxmpi | screws don't strip themselves. and it'd be something i'd remember a decade later | 12:47 |
| zxmpi | one i used hacksaw on swiss army knife to saw a new slot on a screw so i could open the case and the other i remember i used chewing gum to grip what remainded to remove from pc | 12:49 |
| zxmpi | i'll just leave this here https://boingboing.net/2021/10/02/the-history-of-teletext-in-18-minutes.html | 14:25 |
| daftykins | https://i.imgur.com/mJHBZar.jpg - came up once! | 15:34 |
| penguin42 | any options under POST behaviour that might be useful? | 16:16 |
| daftykins | doubt it | 16:24 |
| daftykins | what's interesting is when it gives the power LED but no image, if you press power again, the fan spins up and runs for a bit before it cutting power | 16:25 |
| penguin42 | no, I mean it's failing too early | 16:25 |
| daftykins | yeah, not enough of a failure to trip the LED diagnostic system into showing an issue, too | 16:25 |
| penguin42 | daftykins: I know people who have an M.2->PCIe->serial adapter chains in laptops | 17:25 |
| daftykins | what for? not quite following you | 17:26 |
| penguin42 | getting early serial debug out - I think mostly from Linux kernels, but perhaps also bioses? | 17:26 |
| ball | serial ATA? | 17:27 |
| ball | ...or, just serial? | 17:27 |
| penguin42 | serial | 17:27 |
| ball | I like serial but it makes no sense for storage. | 17:27 |
| ball | Might go out on my bike. | 17:27 |
| ball | ...before it rains again. | 17:28 |
| penguin42 | ih yeh, nothing to do with sotrage | 17:28 |
| ball | Are there (E-key?) M.2 slots with serial pins? | 17:28 |
| penguin42 | no idea - what I was talking about was slots with PCIe so then you convert to mini-PCIe to be able to plug in mini-PCIe serial adapters | 17:29 |
| ball | mini PCIe != M.2 though, right? | 17:29 |
| ball | (doesn't it predate M.2? | 17:29 |
| ball | ) | 17:29 |
| penguin42 | hence why I said an adapter | 17:30 |
| penguin42 | electrically it's still PCIe (assuming it's PCIe M.2) | 17:30 |
| ball | You didn't mention miniPCIe though, which might have contributed to the confusion. | 17:30 |
| ball | That said, I didn't know miniPCIe serial boards were a thing. | 17:31 |
| ball | Let me kick off another Firefox build attempt and if the kids aren't home I'm going out on the pushbike. | 17:32 |
| daftykins | why are you wasting time with that over grabbing binaries? | 17:32 |
| daftykins | sweet, just managed to extract this ruined-head screw | 17:32 |
| ball | daftykins: This is for NetBSD on my Raspberry Pi 2B. | 17:32 |
| ball | daftykins: Did you cut a slot in it? | 17:33 |
| daftykins | hmm that just increases the nutty status of the task xD | 17:33 |
| daftykins | no i didn't have to | 17:33 |
| ball | daftykins: even better. | 17:33 |
| daftykins | https://i.imgur.com/KcBD10L.jpg | 17:34 |
| penguin42 | ball: Are you building it on the Pi? | 17:34 |
| ball | daftykins: I have a few old desktop PCs here that could run (some sort of) Ubuntu but I still want a NetBSD box for some things. This Pi is not quite cutting it so I'm tempted to buy a Chaco Canyon NUC | 17:34 |
| ball | penguin42: Yes. | 17:34 |
| penguin42 | ball: Well, at least it gives you time for a long bike ride | 17:34 |
| daftykins | wouldn't that be more fitting of a VM? | 17:35 |
| ball | penguin42: It'd give me time for several days of bike riding, if it works. | 17:35 |
| ball | penguin42: Usually it fails on day 1 or 2 though. | 17:35 |
| ball | daftykins: I do have a NetBSD VM on my current Ubuntu desktop. | 17:35 |
| daftykins | i managed to remove some fluff from inside the screwhead using a paperclip before i attacked it xD | 17:35 |
| penguin42 | ball: run out of ram? | 17:36 |
| ball | penguin42: Sometimes. | 17:36 |
| ball | penguin42: I've given it a separate disk for swap though. | 17:36 |
| ball | There are some things I can't do on my desktop if the VM is running and of course I have to shut it down (or perhaps pause it) when I reboot the Ubuntu box. | 17:37 |
| ball | ...and sometimes the Ubuntu box just crashes. | 17:37 |
| ball | ...so it would take the VM with it if that were running. | 17:37 |
| * ball fights the temptation to buy an old blade server ;-) | 17:40 | |
| ball | Alright, I'll try a Firefox 68 build. | 17:41 |
| ball | Back after the bike ride! | 17:41 |
| daftykins | old release too? i don't get why you'd bother xD | 17:43 |
| daftykins | ok, ebay subtitute ordered for £32.95 - should work out nicely | 18:17 |
| daftykins | just the main board assembly essentially, might bork Windows activation but eh | 18:18 |
| ball | daftykins: Well I tried 93 but I don't have Rust. | 18:43 |
| ball | ...so it won't build. | 18:43 |
| ball | Let's see whether it can build Python 37. | 19:42 |
| ball | Hello Chris | 20:29 |
