If you happen across that I wouldn't be upset if a copy of it attached to an
email came my way...

Subject: Re: ide harddrive
Evening folks, I am looking for a circuit using the parallel port on a
pc to Ide interface, does anyone have a schematic for one?
Somewhere I have an data sheet for a chip to convert a parallel port into
an ISA slot. No, I don't mean a chip for adding a printer port to the ISA
bus (like the 82C11 does), I mean a chip that connects to a parallel port
(either 'original' or one of the enhanced bidirectional ports), and to
some DRAM, and which allows you to connect anything that you'd normally
connect to ISA on the other side of it. It allows you to read/write any
port or memory location from the parallel port side, it allows the ISA
device to do DMA into the memory hung off the chip (which can then be
read/written from the parellel port), and so on.
I think it was made by SMC, but don't quote me on that.
It looked like a fun device to work with, but I don't know where on earth
you'd find one.
If anyone is interested, I will try and find the data sheet and post the
number of the device.
