Sorry to take so long to reply to the many great contributions to the issue/question. Work is really beginning to interfere with my hobbies.
But now, the rest of the story..... My goal is to connect a BP Micro BP-1600, parallel port connected Universal Programmer, to a computer using USB. BP Micro makes the BP-1610 which does just this. It appears to be the same programmer, uses the same software, but connects via a USB port instead of a parallel port. I have not had a chance to see the inside of the BP-1610 and would really appreciate some pictures if anyone has one, particularly the corner of the PCB that connects to the USB connection. All I have is an Actel Silicon Sculptor 3, also made by BP Micro, that looks like the BP-1710 (with the 'START' button) but connects via a USB port. On the main PCB of the BP-1600 and the SS3 are two, 2 row, 26 pin, connectors, one toward the back edge of the PCB toward the back panel and the other just inside the first connector. The inside connector directly connects to the parallel port on the back of the BP-1600. On the SS3, there is a small PCB that plugs into the same connector, takes a power input, and also has 6 pin connections to the other 26 pin connector. This small PCB has a USB connector that is connected to the back of the SS3 as the USB connection. These observations lead me to believe that it is possible to do a 'USB to parallel' adapter to make the connection. Of course, I don't have a clue about the onboard firmware that might be different to allow the unit to be recognized as a USB instead of a parallel port connected device. So, some 'experimenting' seems in order, after first trying to closely inspect the small PCB and try to reverse engineer it a bit. In the mean time, I have a collection of laptop's and desktop's with parallel port connectors so keeping the programmers humming is not a problem. Just would like to make the 'jump' to the 'modern era'. A project that has been in the back of my mind. I will probably try one of the adapters referred to. Thanks again for all the info.

Hi Luis No problem, and it's much better anyway to hear from someone who's used it:-) I only took a quick look at the web site before and didn't see the self build instructions at that time, but having seen the SMD chip he's using I think asking for a price might be safer:-) I see from your earlier comments that you've used it ok with old programmers but on the page you've linked do he doesn't recommend that, have you come across any problems with this?

I have those and they are not a printer thing, they really work low level. The list of programmers and bit oriented stuff that was reported to work well is big and surely there are more stuff that works that is not in the list... Joe, take a look a check if you app is reported good: http://www-user.tu-chemnitz.de/~heha/bastelecke/Rund%20um%20den%20PC/USB2LPT /liste.en.htm Cheers. Luis Cupido ct1dmk.
