Very nice. It's kind of a shame parallel port phased out when it did -- and that they only bothered making it fully bidirectional in its last, dying days. It was far and away the fastest protocol a hobbyist had for anything small or embedded.
The bizarre thing is it could not beat the AMIGAs port for both speed and flexibility. I only coded for SPP mode though, ECP and EPP modes I ignored as SPP was definitive for _all_ PCs at the time. You could actually FORCE bi-directionality on an IBM XT SPP but was a risky thing to do as damage to the port could occur; but it was possible. The XTs serial port was bomb proof. A have an AD converter built for the SPP along with 8086 assembly code to access it by grabbing two nibbles and creating a byte from them. Not particularly fast but well good enough for most applications.

Hmm, just thought I still have my ancient quad core with an ECP parallel port. I wonder what it would be like using shell scripting to access the AD converter.
Gimme a bit of time and I will let you guys on here know...

Hello.
I have a large number of EPS files and a lesser number of PDFs that I need to convert to GIFs/JPGs using a Unix system. Is there a unix utility or application out there that can do this conversion?
Thank you in advance for any help you can provide.

Problem occurs on one Solaris build. Every time we unzip the Jan CPU, there are several patches that error out (appears to be related to the GIF files). When we unzip the CPU on another Solaris build to a network storage area, we can execute without issue on the original machine.
Any ideas?

Hi guys...
For the AMIGA fans out there...
Not sure if this is the right forum but someone has done a successful working port of gcc for the classic AMIGA A1200.
It contains a very large subset of *NIX commands and now AMIGA fanatics like me can include another platform, within the... (0 Replies)
