There are carriers that provide a SIP trunk that will give you a number with multiple channels. Voip.ms and voipvoip.com are ones I've used that are modem friendly. I know people that want a longer video showing it off. (me)

The Wurst Poster posted:Even at 815kbps the modern internet still sucks. I could double the link speed by just using the T1 but there is no stupid fun in that. Back in my early days I did a whole bunch of testing of setups like this for a major telecom, before 56k was a thing. The Windows ppp stack is poo poo, and you get rapidly diminishing returns on additional lines. You might be able to improve performance by clamping MTU down to 280 Do not get me started on how bad the mppp implementation on Linux was at the time. All the documentation talked about setting it up with only a few commands, but the fact that it only worked on ISDN modems and only for two channels wasn’t mentioned unless you read some really obscure mailing list archives or understood the code.

3D Megadoodoo posted:This is probably a dumb-rear end question, but can I simply replace an AMD K6-2 CPU with a faster one, and it'll work? Most Socket 7 boards have jumpers for voltage, bus speed, and multiplier. A few, like a weird PC Chips board I have, use software settings in the BIOS. That said, it's usually easy to do with just a few jumpers, not like switching CPUs on a 486 board. The biggest pain point is getting the right multiplier and bus speed. Like if the motherboard only supports 66MHz bus a K6-2/400 needs a 6x multiplier. If your board doesn't support high multipliers, the good news is that the CPU interprets a 2x multiplier as 6x. Another issue is checking the voltage. Most K6-2s run at 2.2V but they can range from 2.0-2.4 depending on revision. Individual chips might tolerate higher or lower but you want to match if you can. Older boards especially were manufactured with guesses at what AMD was going to put out and might not have the right options. Finally, if you luck out and get a K6-2+ (sometimes just sold as regular K6-2) you need to have BIOS support in the motherboard, otherwise it probably won't boot right.

A "real" Super Socket 7 board should support 100MHz FSB and at least a 4.5x/5x multiplier so if it's that you're good barring some weird voltage situation. Just that lot of boards billed as Super Socket 7 didn't meet full expectations, and a lot of boards had K6-2 support without 100MHz FSB, like that PC Chips I mentioned. Which will hurt performance if it doesn't have it, but faster is still better even at 66MHz FSB. It should still work anyway. You'll just have to check the settings that get you closest to what the chip is labeled as. The board's jumper settings are probably on The Retro Web if nothing else.

EVIL Gibson posted:???? It's not a motherboard thing, it's a CPU thing. And unfortunately not universal, it depends on the CPU stepping. Steppings 7 and earlier will accept a 2x multiplier, but steppings 8 and up (CXT core) by design interpret a 2x motherboard setting as 6x. They're not gonna hit 600MHz on 100MHz FSB, but the design was to allow 400MHz speeds on boards that are limited to 66MHz FSB, 450 at 75MHz, etc. The good news is that as far as I can tell (nearly?) all K6-2 CPUs that are labeled 400MHz or higher are Stepping 8 or higher. The other good news is that if your motherboard supports higher bus speeds you don't need to worry about it and can just use a normal multiplier like in your screenshot. Now getting even the latest models to 600MHz is the real trick. I've seen people do it, but too much trouble for me to try it on an ancient board today.

I wanted to go down the 3D printing path for that purpose myself, for a missing battery cover on one of my Sinclair Sovereigns, but this nonsense is what I'd have to replicate: Look at this curvy, thin, stamped steel thing. I haven't modeled anything other than basic shapes in CAD -- and this seemed incredibly unlikely to succeed -- so I gave up on that idea. Now my plan is to use the battery cover I do have to create a silicone mould, then cast a high-strength resin duplicate. But if you/others think I'm wrong and 3D modeling could work, I could use a really good resource to learn how do

So that would explain why the floppy controller isn't recognizing any drives on the PS/2 I bought. Time to pick up some new 4.7uF 35V capacitors and replace the burnt-out husk of that tantalum (and probably the one next to it just to be safe).

No major retro changes around here, but I am happy to report that this one Lacie FireWire 400/USB external drive uses a SATA plug internally and doesn't care what drive it talks to: I think it's a "Porsche Design" model of some sort, no real markings on it. So now I have a 1 TB FireWire SSD, pretty neat! Might try to make a multi-boot installer drive at some point, need to get a fresh install in the G4 AGP at some point after I stole the hard drive for the iMac G4.

I very much your confidence in my abilities, no matter how misplaced it may be! I'm pretty sure I will eventually try it -- my casting materials are about 2 years past their shelf life and I don't feel like spending another $80+ when I'll be wasting 90% of the silicone and resin. By the way, I'm pretty sure I do need the metal tabs eventually. I think Sinclair used them to bridge the batteries in series, because...

I don't know if it is a matter of age or being an American, but it seemed to me growing up that very few families I knew had VIC 20s, but the Commodore 64 became pretty common. We always kind of looked down on the VIC 20 as the younger, weaker sibling.

And yes the VIC-20 was absolutely weaker than the C-64, but it also predated it by two years during a time when home computer technology was advancing very rapidly. I can highly recommend the book "Commodore - A company on the edge" by Brian Bagnall. It's a very good in depth biography of Commodore as a company from its start as a calculator maker up until just before the Amiga. There's a sequel called The Amiga Years but I haven't gotten around to reading it yet.

Collateral Damage posted:And yes the VIC-20 was absolutely weaker than the C-64, but it also predated it by two years during a time when home computer technology was advancing very rapidly. The C64, despite being superficially similar in design and priced aggressively, was really spec'd for use with a disk drive, and in that sense was really punching up to compete with the Apple II+/IIe. And yes, two years was an eternity back then. After all, only three years after the release of the C64 did the 16-bit machines start to come out (Amiga 1000, Atari ST, etc.).

Just doing some tidying and found what must have been one of the last SD camcorders ever sold: The interesting thing about it I think is it solves almost all common camcorder issues, such that by MEGAPIXEL era standards this thing is basically the ultimate camcorder: - 60gb hard drive stores up to 20 hours of DVD-quality video, or 40 hours in LP mode. - 25x optical/4000x digital (lol) zoom - Each video is a plain MPEG2 file which can be downloaded at USB 2.0 speeds Of course we enjoy all of this convenience and more with any modern digital camera and smartphone, but for anyone used to the mess of tapes and capture cards, this would have been revolutionary. And of course, having perfected it, we threw it all in the trash and made our lives hard and expensive again by demanding HD everything.

My camcorder story is that I got an SD Canon in tyool 2008 or so that had shittier video in a stupid .mod format that is just renamed mpeg I think and it just broke after 3 years of use. https://www.youtube.com/watch?v=tvzwCPoXclQ Now that was the poo poo. All camcorder footage from the late 80s is a special kind of garbage though. I was envious of my uncle who had one which had stop motion functionality and I just dreamt about what I could do with that and my LEGO.

snorch posted:- 60gb hard drive stores up to 20 hours of DVD-quality video, or 40 hours in LP mode. Dealing with a horrendous amount of MiniDV tapes still constantly, I’m both jealous of this but also cognizant of how much of my footage I likely would’ve lost over the years with no easy way to back it up. Except there is an easy and obvious backup… MiniDV tapes. Dammit, I’m back to where I started! (The quality must take a crunch at those numbers too, MiniDV is a 13gb/1 hour stream in DVAVI, editing those MPEG2 files might not quite be as fun.)
