Old-timey, obscure & obsolete component thread

>>62014897

Is that a serial board? Because they may be obsolete for consumers but they sure as hell aren't for electrical engineering. I use those every week at least a few times.

>>62014923
It's a COM-2CL-PCI non-isolated RS-232C 2ch card. Serial ports have been gone from consumer computing for so long that I just assumed it's something outdated. Specialization & low volume explains the high price.

The one I got the pic from was listed for $250.26 - $272.14. I had a link to it but had to delete because of spam protection. Maybe it's a rare one?

Were the ink cartridges transparent or am I remembering wrong?

They're expensive only if you want a brand-name and/or a fully insulated one. Regular RS-232 cards are cheap as peanuts, plus you can get mini-ITX mainboards with 2-6 RS-232 ports built-in.

>>62018108
Gotcha! So, um... what do these do? What are they used for and how? I know I can look it up but I'd rather ask you

I use these to back up GOG games. Not sure why.

>>62018223
In POS equipment, they're used to connect receipt printers, barcode scanners, card readers, currency/coin validators and other similar stuff.
In industrial equipment, they're used to connect various external controllers (e.g. in CNC machines), although RS-485 is often used instead of RS-232.

Why are serial ports favored over USB in such equipment? My best guess is... sturdier physical connection?

I don't know much about this stuff, but I think writing software or drivers to communicate over serial ports is probably less complicated and easier than for USB

Thanks for the info, anon. I also found a video that illustrates how RS232 is faster than USB when it comes to tiny packets of data, another possible reason it's preferred in those applications. https://www.youtube.com/watch?v=6dFAycd89cA (in German but self-explanatory)

>Why are serial ports favored over USB in such equipment?

USB peripherals of that sort do exist, but often just have off-the-shelf USB-to-RS232 bridge chips (e.g. FT232) inside.

RS-232 is just significantly easier and cheaper to implement in hardware and software. It needs no drivers on the PC side (why there is no generic serial communication driver for USB - in the same vein as generic USB mass storage and USB audio drivers - is beyond me), and no complicated software layer on the peripheral side. Compared to USB, you lose throughput speed and the ability to use hubs, but that isn't an issue for all of the uses listed above.

What about MPEG encoder cards

Shit was pretty cash in mid-to-late 90s when consumer CPUs couldn't yet handle real-time encoding in full PAL/NTSC resolution and hard drives couldn't yet handle raw recording.

I did a P2V of an old dispatch system a few years ago with one of those Connor drives, the thing had been running since 1991.

Looks like a DIY quad processor from before multi-core processors

>>62018868
At this point of adoption, writing a generic serial communication driver for USB might be futile. Or it might be earth-shattrring, idk!

>>62018922
If my 386 PC had PCI slots I would be using one just to play a video in windows 3.1 for shits and giggles. They still make good ornaments though.
>>62018992
Old HDDs are really sturdy. That 170MB one I posted still doesn't have any bad blocks. By the way how did that old dispatch system communicate with drivers?

I think those were server boards. Variations of that design were common.

>>62018998
Why a combined sound card and SCSI controller? It's so random. Do they have some kind of chip commonality?

>>62014897
is that a modded raspi? what's the big golden connector on the bottom right for?

>>62019102
>>62019188
Nope, it's a telephony card. I think it multiplexes 64 lines per pair of BNCs or something. It's a Dialogic DualSpan, if you yant to look it up.

Those failed because they were literal Flash memory cards - as in, nothing but bare Flash memory inside. This led to a shitload of bugs and dumb restrictions on speed and capacity.
