00:26:42 <flyback> !coffee flyback
00:26:45 * EEVBot throws screaming hot coffee at flyback
00:26:52 <flyback> EEVBot, botsnack
00:53:43 <arch> how do you do, fellow intel 486 users?
00:55:49 <flyback> yeah I got 2-3 486 mb's
00:56:01 <flyback> sadly no ps/2 ports so I will have to run non optical serial mice
00:56:07 * flyback pukes
00:58:14 <K> ha look at that pleb
00:59:47 <flyback> there is a rare optical serial mouse but it's $40 and requires a special mat
01:00:02 <flyback> I have a 286 and 386 same day
01:00:25 <flyback> will have to consider one of these projects that modifies the board to add a ps/2 port or a protocol controller microcontroller board
01:00:30 <flyback> such as a rpi pico
01:01:15 <K> hm, but what does a 486 have, if not ps/2 ?
01:01:36 <flyback> serial port
01:01:47 <flyback> ps2 mouse is actually a function of the keyboard controller chip
01:02:08 <flyback> some people have resorted to swapping their keyboard controller chip to one with both keyboard and mouse pins
01:02:18 <K> wierd
01:02:34 <flyback> you can also get a bus mouse port but bus mice are rare and non optical
01:02:36 <flyback> pointless
01:02:41 <K> i dont think i've seen a 486 without ps2 keyb and mouse ports
01:03:24 <K> maybe some wierd industrial grade does not
01:05:29 <Vampera> K, most parts-built 486s didn't have PS/2 ports
01:05:44 <K> hm
01:05:57 <Vampera> there were leagues of Baby AT Socket 1-3 motherboards with only a DIN connector for the keyboard
01:05:58 <K> not my exp
01:06:06 <Vampera> including ones that I own

01:06:25 <Vampera> this is the one I own

01:07:42 <EEVBot> [url] Search boards - TRW | theretroweb.com
01:07:48 <Vampera> here is an entire list of 486 motherboards with no PS/2 connectors
01:08:11 <Vampera> though it seems a few have them, most of them are just AT style with the full size DIN
01:08:25 <K> huh ok
01:08:46 <Vampera> This was a common design up until ATX took over with the removable I/O plate
01:08:50 <K> i remember dins and serial mice on 386 systems
01:09:05 <Vampera> roughly around the later Socket 5/7/8 era
01:17:38 <flyback> Vampera, some of those baby at do have a ps/2 header
01:17:46 <flyback> so you just need a passive cable adaptor
01:17:49 <flyback> sadly mine does not
01:45:27 <arch> i know about USB2-to-RS232 adapters, which are handy for hooking up to server serial ports. is there the opposite? so say you have an ancient PC that only has RS232. is there an adapter that can allow you to hook up USB devices?
01:48:01 <flyback> no
01:48:06 <flyback> but there is a isa usb card
01:48:10 <flyback> however it's not a true usb bus
01:48:29 <flyback> it's a microcontroller that speaks some usb protocols and outputs a serial or parallel bus
01:48:48 <flyback> it does allow flash drives to work in dos and someone used it on a non pc to do usb keyboars and mice
01:55:46 <Vampera> arch, no, USB is an order of magnitude faster than even the fastest RS232 links, and requires a lot more to be functional
01:55:58 <Vampera> even USB on ISA is sorta a very niche and uncommon thing
01:56:07 <Vampera> the oldest you'd commonly find USB controllers is PCI
01:56:12 <arch> oh
01:57:57 <Vampera> of course most peripherals you'd want USB for has non-USB counterparts in various forms
02:43:10 <flyback> like I said
02:43:16 <flyback> it's NOT a usb controller on isa
02:43:18 <flyback> not possible
02:43:30 <flyback> it's a usb enabled microcontroller that can spit out a serial or parallel bus
02:43:59 <flyback> usb is very much built around the pci/pci-e bus

07:20:50 * arch puts flyback on the magic school bus
07:38:03 * Vampera puts arch on the magic short bus
07:47:55 * steve30 nibbles on Vampera

10:05:32 <MrMobodies> "The patient decided that the bed pan was not for him"
10:05:42 <MrMobodies> very degrading if they won't let him go to toilet.
10:07:22 <MrMobodies> 22:31 looks like a terrible state where the police there was to act like carers

12:08:35 <steve30> In this week's news: "Officers located the man at Asda, off Craven Way, at about 12.50pm and found that the item he was carrying was an umbrella."
12:24:01 <MrMobodies> an umbrella, how petty
12:56:15 Quit: steve30 ([email protected]) Quit: <Baljem> steve30: by the way, I had the most bizarre dream the other day that someone came in here and seriously flipped their shit over your quit message and why aren't the ops /doing/ something about it

13:35:06 <MrMobodies> doing something the buyer's fridge that the buyer cannot undo.
13:35:42 <MrMobodies> wasn't brought cheap, wasn't brought with adverts, why should it show them.
14:19:50 <rust_collector> I hope they arrested umbrellaman

15:15:57 <MrMobodies> I was in Aldi today and I brought quite a few things. On the self checkout tills as the only two tills had a long queue but not many people there
15:16:35 <MrMobodies> After I paid, I was putting things in a bag, as these were very small checkout tills
15:16:44 <MrMobodies> ooops cut and paste damn
15:16:49 <MrMobodies> ooh scroll
15:17:24 <MrMobodies> anyway this well English speaking African man and his wife came besides me
15:17:43 <MrMobodies> the man took my bag and I said "Hey! What you are doing!"
15:17:53 <MrMobodies> "Me now using this till"
15:18:01 <MrMobodies> "I am not finished yet"
15:18:12 <MrMobodies> "Tough mate, I am now using it"
15:18:51 <MrMobodies> "No, you stay away, I am using it, I am not finished and there's empty one next to me"
15:19:04 <MrMobodies> "tough mate you move out,,"
15:19:19 <MrMobodies> I called the young lad staff member"
15:19:35 <MrMobodies> i said "this man is being difficult, I haven't finshed and he is shoving me out of the way"
15:19:55 <MrMobodies> anyway this man argued with the attendant and the atttendant said just go to another till.
15:20:12 <MrMobodies> he said "if you told me you haven't finished I would have gone to another till"
15:20:37 <MrMobodies> I said "what does it look like I was doing and I told you I hadn't finished... LIAR!"
15:20:51 <MrMobodies> I felt very threatened before I called the attendant over
15:20:58 <MrMobodies> what do you think of that behaviour?
