Strange Keyboard

by lyosnorezel＠yahoo.com

Hey ya'll... please take a look at these three pictures: http://geocities.com/lyosnorezel/keyboard1.bmp http://geocities.com/lyosnorezel/keyboard2.bmp http://geocities.com/lyosnorezel/keyboard3.bmp The first two show the keys, the third shows one of two connectors that it apparently interfaces the computer with. The two "plugs" are 8pin jacks... like cat5 but in a wider, more spread out form. The most noteable things about this keyboard are as follows: Interesting Keys: Cancel Move Help Action Over Type Finish Copy Lock Code (instead of ctrl) shift + 6 would give you the "cent" or "penny" sign (a "c" with a line though it) F1, F2, F3, F8, F9, F10 all have lights Return instead of Enter 1/4 1/2 fraction key... 1/4 is on top... key is next to "P" Number pad: GO Next Arrow Pad: Mark Bound Anyone know system this keyboard is from? The only markings are from the company "Datapoint Corporation" "Model No. 93-1222-001" "Serial No. 978870" It's UL and CSA certified. Other then this there are absolutely no markings. Thanks.

Ultrix V4.2 sources et al...

I have this service because it is the lowest-priced business Inet service from WorldCom/UUNET (now called MCI). It had to be a *business* service from them in order for me to get a Class C NET from them, and it had to be WorldCom as they were the only ones who just gave it to me without charging me an extra arm and a leg for it. (Also WorldCom was cheaper than all other business Inet services, though again I only considered business services as they are the only ones that give full Class C NETs.) Except for being slow (but that's fair, you get what you pay for), I'm very satisfied with UUNET and won't switch. MS

R80/RA81 diagnostic experience?

by dwight.elvey＠amd.com

Hi Most all hard disk heads will damage the surface if rotated backwards. This is because the back edge is sharp enough to cut you as well as dig into the surface.

R80/RA81 diagnostic experience?

by brad＠heeltoe.com

[resend - looks like original got lost this weekend] Hi, If anyone has diagnostic experience with an R80 or RA81, I'd like to pick your brain a little... If this is better done off line, email is fine. I suspect not everyone is interested on how to revive an R80 :-) (why *I* find it infinitely fascinating is something I'll never understand) I have an R80 which does not spin up or come ready: - All of the voltages are good (all the ones I checked anyway). - The drive belt had come off but I managed to get it back on - I can't seem to get it into diagnostic mode; the 8 leds' on the bottom pcb show 0101 0101 (hex 55). - When it powers up all of the external lights go on and stay on. - if I reset (click the switch ont the pcb to "R", the lights go out - if I then push the run/start it lights and after about 5 seconds the fault light comes on and run/start goes out. - if I push the fault light all lights go on and then the right most one stays on - push fault again and they all go out (I can then repeat the run/start sequence) I'm guessing the above behavior means the micro is operating, but then I set the rotaries to "FF" and hit 'enter' (i.e. put the toggle to 'E') the led's don't change at all. The manual says they should flash and change as a I enter diag mode. I wanted to use diag more to force a spin up but no joy. Does the unit have to be connected to a controller to go into diag mode? I have an RB730 which this connects to. Connecting is does not seem to really change it's behavior. -brad

Hi, Do you still have the V4.2 source online anywhere? Trying to copy it from harhan.org is painful at best. Regards, -Steve Davidson Hollis, NH.
