I have this programmer and I have used it for a couple of months now.
It is a serial port programmer, not LPT. No external ISA card required, the command software is actually inside the unit. You will need a simple $3 adapter that is sold at places like Fry's. It is very nice in that you can connect it to just about any more modern computer's 9 pin serial port (COM1). I have mine hooked up to an XP Home box.
I never bothered with the old software for the burner, it is compatible with Windows Hyper Terminal, once you set it to use COM1. The manual has the max speed at 38,400. No other software is required, everything is self contained.
I would highly recommend you get yours upgraded, the commands are a lot easier to use.
Member Sprout upgraded mine. Depending on the version of the software, it can either be easy or will require wire jumpers to be installed at places around the board.
Either way, when you get in Hyper Terminal, simply hit enter and the burner should respond and list a software version. The commands you use will be tied to that version number.
It is a very nice burner for EPROMS up to 27512. Past that you will need something more modern.
EDIT: this is the best info I could find on that $3 adapter, I used to have the tiny box for it, but it's trashed. "DB-25 to DB-9 adapter"
