Sun SparcStation 4 - Need Help to Hook up cables, & Docs

Hold your horses :) We'll get you squared away. Suns of that era use a proprietary keyboard connection; nothing is PS/2. You plug the mouse into the keyboard and then the keyboard into the system. Older Type4 keyboards will work but you want a Type5. The DB25 labelled A/B is a serial port with ports A & B (ttya, ttyb) combined. Sun would sell a splitter cable. Standard cabling will give you access to the "A" port. With no keyboard and monitor hooked up, using a serial cable with null modem (9600-8-n-1) you should be able to get onto the console of the system and see how it is set up. Look at the website below, and scroll down, and you'll get some diagrams and photos of how the back of a Sparc4 will look and what the ports will do. http://classiccmp.org/dunfield/sun/index.htm The monitor should hook up via 13w3, but without a keyboard you're not doing much of anything. On boot the Sun will search for a keyboard. If there is none there it will change its default input/output to the serial port (ttya which we talked about before.) Any PS/2-style hookup on the back of a monitor may be for 3D glasses or similar, but I'm not familiar with those setups on Sun systems. What's the model number of the monitor? Did you get a keyboard at all? On Sun, May 3, 2015 at 9:27 PM, Kip Koon <computerdoc at sc.rr.com> wrote: -- -Jon +32 0 486 260 686
