Firstly I don't know where to put this so if it is the wrong forum then chastise me... ;oD
I built the hardware and wrote the software for an Audio Oscilloscope DC-100KHz in 2001 for the A1200(HD) via the AMIGA parallel port. It clocks the port at 200KHz, although 250KHz was easy enough via a 0.5 metre length of 25 core parallel cable. (I did successfully clock the port at around 500KHz but ONLY with direct connections to the port.
Full constructional details are on AMINET and if anyone wants to look I will post a pointer.
However I did do a GIF anim of the display and this is almost EXACTLY how it works.
Obviously I desgned the GUI for it and the push buttons when depressed, stay depressed until another range is required.
The unit ALWAYS defaults to 30V/Division AC and you cannot access the Y-Amp buttons until you press the VERT button first. This was for safety reasons.
EDIT:-
DOH!
I though I put this in "What's On Your Mind".
Sorry guys, if the Admin staff could move to that forum I would be grateful...
TIA.

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.

Hi Everyone,
I am trying to use "convert" to create a movie from .bmp files. I have about 100 .bmp files which I would like to include. I use the following command:

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)

ports
ports(7) Miscellaneous Information Manual ports(7)NAME
ports, port_names - Device (tty and lp) names for serial and parallel ports
SYNOPSIS
Default Serial Ports:
/dev/tty00
/dev/tty01 (not present on a single-port system)
Parallel Port:
/dev/lp0
DESCRIPTION
AlphaStation and AlphaServer systems provide one or two 9-pin serial communication ports. These ports are usually labelled 1 (COMM1) and 2
(COMM2), but they may be identified by different icons. Using the appropriate serial cable and terminator, you can connect a serial
printer, external modem, or character-cell terminal to a serial port. Most AlphaStation and AlphaServer systems also provide one parallel
port, for use with a parallel printer.
When you add a device to your system, the installation documentation may instruct you to map the device pathname to the port. These
devices are located in the /dev directory.
For serial-line ports, the two default device pathnames are: This pathname always maps to 1, COMM1, the lowest port number, an icon for a
terminal console, or the only serial port (on a single-port system). This pathname always maps to 2, COMM2, the next numbered port, or (if
one serial port is labeled with an icon for a terminal console) the remaining serial port.
If your system hardware has been extended to include additional serial ports, the pathnames /dev/tty02, /dev/tty03, and so forth, may also
be available to you. However, most systems have only /dev/tty00 and /dev/tty01 as the device pathnames for serial ports.
The one parallel port on an AlphaStation or AlphaServer may be labeled with the word printer or a printer icon. On some systems, the paral-
lel port may not be labeled. The device pathname for the parallel port is /dev/lp0. Currently, Tru64 UNIX does not fully support parallel
printers, so fewer devices are connected to this port as compared to serial ports.
If you are connecting a terminal console to your system, it must be connected to the serial port mapped to /dev/tty00. For other serial
devices, it does not matter which of the serial ports you choose for the connection. For example, suppose you are setting up a system that
has two serial ports, labeled 1 and 2. You intend to use a serial-line terminal rather than a workstation monitor as the system console and
also want to connect a serial-line printer to the system. In this case, you must connect the terminal to the port labeled 1 (with the
device pathname /dev/tty00). Therefore, you must connect the printer to the remaining port labeled 2 (with the device pathname /dev/tty01).
If, for the same type of system, you intend to use a workstation monitor as the system console, it does not matter which serial port you
use for a serial-line printer or modem. In other words, you can connect the printer to either port 1 (with pathname /dev/tty00) or port 2
(with pathname /dev/tty01). When prompted to enter a /dev/tty** pathname by the lprsetup script or the Print configuration tool in the CDE
Application Manager, you would specify /dev/tty00 if you connected the printer to port 1 or /dev/tty01 if you connected the printer to port
2.
See the System Administration manual for more information on setting up consoles (including remote consoles) and printers. See the
modem(7) reference page for more information on setting up modems.
