RDI BriteLite IPX keeps going to white screen

by Cameron Kaiser

I've been trying to do a little work on the RDI BriteLite IPX I have here, but when it runs more than a few minutes the LCD just blanks out white. The machine seems to still respond to commands, so it seems like it's something with the display hardware. Even powered off and back on it won't go back to normal until I let it sit for awhile. I suspect heat is part of the issue and it certainly feels warm; there are two loud cooling fans inside, but with the case off and checking airflow the fans do seem to be working. Having the case off doesn't make the display any happier though. One fan is in the power supply and another fan is in the (LCD?) inverter board. Finger-checking large chips while in operation doesn't burn the skin. Anyone familiar with this issue? I suppose I could look for a SPARCstation IPX to take the motherboard out of and replace this one with it, but it seems more like the problem is in the display, which is a custom part. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser(a)floodgap.com -- Fish will never understand fear of deep water. -- Tanner Greer -------------

WTB: Kinetics/Shiva FastPath 4 or 5

by Jonathan Chapman

All, I've been looking for a Kinetics or Shiva FastPath 4 or 5 for a while, without luck. Don't know why I didn't think to ask on the various lists! If anyone has one they'd like to part with, let me know off-list. Thanks, Jonathan

ISO someone to refurbish two IBM 010 card punches

by LJW cctech

Hello all, Is there anyone out there that would be prepared to tackle restoring a couple of IBM 010 card punches functionally and cosmetically? This is a paying job! These are the small tabletop units. One is manual: https://flic.kr/p/2nVAJeg The other is motorised: https://flic.kr/p/2nVB8Pa They are apparently complete but will need cleaning, repainting and adjusting, and whatever you can do with the key-tops. The manual one was used by the current owner in 1962 so has some sentimental value! They are in the USA but we can get them to you wherever you are. If you know of anyone who might be interested then feel free to forward this email. -- Lawrence Wilkinson lawrence(a)ljw.me.uk The IBM 360/30 page http://www.ljw.me.uk/ibm360

Re: cctalk Digest, Vol 97, Issue 67

by Mark Kahrs

Let me add that Howard Sturgis' dissertation "Post-mortem for a Time-sharing System" is great reading. It's unusual that failures are documented but this case study is worthy.

PALM assembler now available (5100/5110/5120)

by Steve Lewis

Wanted to pass along that PALM has been added as a target to the Macro Assembler AS. This means writing some assembly stuff for the old IBM 5100/5110/5120 systems. Assembler available here: http://john.ccac.rwth-aachen.de:8000/as/ So no one has to re-type it, the "bounce" sample is located here: https://github.com/voidstar78/5110VEMU/blob/main/bin/sample1_palm.asm Norbert has the online IBM5110 emulator, but it doesn't have a way to "script inputs". Not sure if he's in the mood to crack that open again, but it would be a nice feature to add (a kind of "File Open" and just script the content of the file like typing on its emulated keyboard).. Alternative way to test some compiled assembly is to script it into the 5110VEMU located here: https://github.com/voidstar78/5110VEMU/tree/main/bin (Wintel builds, uses pdcurses which might not be too hard to port to other systems) Or if have a physical system willing to power up, you can use a serial port as a proxy to the keyboard: https://github.com/voidstar78/KBD5110/tree/main/CODE Screen is port mapped at 0x0200, so drawing stuff is easy. I'll work on an example to poll keyboard inputs - then we're in business for some interactive software content :D (well, will need some RNG solution next) Cheers!
