I heard that with USB, data is only sent through two wires, and alot more decoding is required. This also requires higher memory space in the external circuit just for decoding, AND this overhead of decoding can reduce speed, especially if it is executed every time.Not only are USB plugs smaller (and cheaper), with less lines in the cables, but they have a LOT more features. Not to mention, the average computer gives you about 10 of them.
It is when you have someone like me who does not want to upgrade the O/S from Win95.Also, for the average design engineer, it's not really any harder to throw in a USB chip, or a microcontroller that supports USB, instead of a parallel driver or USART. Similarly with PCI slots, you can get chips with that already integrated into them.
So this is how these computer manufacturers make money... Rip out the old ports, and put in a USB port, and then SELL A CARD to install the ports. This is ridicuous!If not, you can get a PCI card with 2 of each for about $20.
I don't use manuals. In fact, I know every feature on my motherboard, AND believe it or not, I solder my jumper connection and remove the jumper and the pins, so that I don't leave a jumper sitting in the same spot for years, and I will have an extra jumper to play with.Or meaby check the motherboards manual.There they describe evry conector and jumper you can find on it.You may even find a usable feture that you didnt know before.
Assuming my friend's motherboard has this header, where can I buy the connector that converts the header to a gameport socket?Check the mobo for the header connections....most PCs just have a 16 pin header for gameports anymore....

Not for DIY projects maybe, but from a commercial point of view, they generally suck.mstechca said:they don't necessairily suck.i_build_stuff said:Parallel / serial ports might be super-easy to connect stuff to, if you're breadboarding simple gate-level projects, but they kinda suck for more complicated designs that you want to sell.

Well that speed will still be a heck of a lot faster than a serial and much cheaper / less cumbersome than parallel!I heard that with USB, data is only sent through two wires, and alot more decoding is required. This also requires higher memory space in the external circuit just for decoding, AND this overhead of decoding can reduce speed, especially if it is executed every time.

I am afraid you, being a user of win95 and into interfacing your own projects to an IBM compatable machine are overwelmingly in the minority, and large manufacturers cannot afford to care about the minority!It is when you have someone like me who does not want to upgrade the O/S from Win95.

No, it is not ridiculous - This is how technology moves on! get a grip and accept it!So this is how these computer manufacturers make money... Rip out the old ports, and put in a USB port, and then SELL A CARD to install the ports. This is ridicuous!

So? just because you don't use a manual for your computer doesn't mean to say you shouldn't use it for your mates computer!I don't use manuals. In fact, I know every feature on my motherboard, AND believe it or not, I solder my jumper connection and remove the jumper and the pins, so that I don't leave a jumper sitting in the same spot for years, and I will have an extra jumper to play with.

so technology moves on, and people will have to throw their 10-year old printer out and buy a new one to continue printing???No, it is not ridiculous - This is how technology moves on! get a grip and accept it!

Why are you using Win95?, what was wrong with your abacus?.
Excellent point.Nigel Goodwin said:Why are you using Win95?, what was wrong with your abacus?.

They don't necessarily suck for you.Coz you are the DIYer who doesn't want to bother using more complecated ports than LPT or RS232.mstechca said:they don't necessairily suck.
A fullspeed USB transmission supports nearly 1 mega bytes per second EXCLUDING the protocol decoding cost,isn't that fast enough for you?Or use a high speed USB transmission at 40 times the speed.The "excluded" protocol cost contains CRC checks,which make the data acquisition MUCH more reliable than parallel and RS-232 transmission.Think tiwce before making your sensation.mstechca said:I heard that with USB, data is only sent through two wires, and alot more decoding is required.

Nigel made his good point which I wouldn't repeat.mstechca said:It is when you have someone like me who does not want to upgrade the O/S from Win95.Also, for the average design engineer, it's not really any harder to throw in a USB chip, or a microcontroller that supports USB, instead of a parallel driver or USART.

Thinking your way,it is ridiculous.Because you can't live without the old ports.However,don't expect everybody who buys a computer is a DIYer like you.Go to a computer market and take a look yourself.Most of those guys don't even know what those ports and slots over the mainboards are.There're nurses,clerks,uncle chess,HDTV fans etc.How many of them would care whether there is an LPT at the back of there computer?They don't even use peripherals!And look at those kids with all sorts of joysticks.I have two myself.The older one is a Logtech Wingman with gameport interface.I always hate the wide cable,and it's not really easy to align and plug the connector at the back when I'm in the front.Oh footplates!I need a footplate for rudder control when I'm playing flight sims.If I want both the gameport-based joystick and footplate installed,where do I find the second gameport?See?You are the minority.Think about why they name the new stuff UNIVERSAL Serial Bus.Because every peripheral manufacturer is tending to build his devices following this standard,and computer users won't need to think too much about the ports they don't recognize.The goal for implementing USB standard is for maximum user convenience.And the price is,of course,the sacrifice of brian work of developers.mstechca said:So this is how these computer manufacturers make money...
