Hello to all,has anyone experience the lack of the parallel port on his laptop,and what other solutions might be available except the obvious,to keep the living without it with no such a kind of a programmer,since the express card/54 to paraller is nearly impossible to find it.
The usb programmer is quite expensive to buy it,and also difficult with hard-to-find components to fix your own.Also the program recognizes a classic 0x378 address parallel.

There are some USB parallel cables available, not sure if it will work for you.

Usb parallel port cables don't work with programmers. This question pops up regularly. Get a usb programmer - sorry!

Huh? USBasp, as a kit with all parts, will cost you less than €20 (incl shipping to Greece). What will the USB to parallel cable + a parallel port programmer cost you?

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.

USBasp will cost you about $8 ready built and delivered to your door. Mine took less than a week to arrive.

Not only that, if you like fiddling, you can install different firmware on the USBasp and it behaves like an AVRISP-2. i.e. you can run it with Studio.

Just to note that there's almost no USB-parallel style add-on you can find that would allow it to drive a parallel bit-bang programmer anyway.

(what's more you cannot find one for the $8 that David says a USBAsp would cost anyway!)

On ebay search "AVR programmer" you'll see loads of these:

Either BuyItNow and pay the top price or try a lower bid on an auction item as many will sell with just one bid.

One more problem among the others is that the programmer is not for AVR,avrisp mkii that i already own is cheap,reliable until now and does the job fine and there are many clones in the market if you dont buy the original.
The parallel programmer comes with an Fpga develompent board for free,the usb type costs 150$ and just for any fun that comes from experiments the cheapest solution is always the best,not to mention the absolute free.
A pc that comes from second or third hand running the XP windows and has a parallel port seems as the only solution.

Interesting to note that the $60+ Atom motherboards generally have a real parallel port. Should be possible to cobble together a whole PC for about $100:

A client requested a USB interface to update the AVR and a FPGA built on to their custom audio processing board.

If you research XSVF Player and have the time to mess with it....

Pick up an old Dell Latitude, I use several. They have a full compliment of ports and should be really cheap.

geoelec,
I feel your pain. I use Atmel CPLD's and I can only program them via parallel port. I generally keep a few LAtitude machines around that have parallel ports on them for programming the cpld's and other tasks.

Go with the extra laptop. Use it for backup purposes as well.

Or an IBM ThinkPad T40(I think there may have been a couple of later models as well - not sure). I bought one on Ebay a few years back for controlling certain evaluation kits that NXP make - parallel port bit-banging I2C.
