Re: Looking for Bruce from Future Dimensions, Compuware

Yes! These are the octal-value asci characters, as far as I understand, for the Point 4 IRIS system. That's for identifying the Televideo connection! It's probably purely anecdotal, but back in the day, the address of this local computer servicer/reseller was: FUTURE DIMENSIONS,INC. 847 N.

Looking for Bruce from Future Dimensions, Compuware

Interesting story (well maybe for some). For any of you who have followed my projects, here is some context: It is one and the same company who used both the Point 4 IRIS systems and the Convergent Technologies MightyFrame systems that I have spent the last 3 years reconstructing and restoring.

Re: Seeking any SGI 4D "Twin Towers" system as well as early IRIS 68K hardware

Ian, could you reply with a link to what you refer to as IRIS 68k hardware? This catches my attention, and I just want to make certain that this isn't related to what I've been working on. Maybe it's just a coincidence, because I've been restoring an IRIS OS (from Point 4), and independently,

Thanks for sharing that, Ian! Your story is exactly what I was hoping to gather here. Does our dissection of the LU0 make any sense to you? On Sun, May 8, 2016 at 3:54 PM, Ian S. King <isk...@uw.edu> wrote: > On Sun, May 8, 2016 at 1:31 AM, Microtech Dart <microtechd...@gmail.

Calling for [Point 4] IRIS programmers

Hi, all. It's been a while since I've discussed anything here. We've made a lot of progress re-constructing a couple of Point 4 machines (as much as one can without the actual hardware), yet still need some help from a few knowledgeable folks in this 35+ year old OS. It was built on the DG Nova

Re: QIC capstan

http://terrysrubberrollers.com/ Terry has rebuilt about a dozen rollers for me over the past 2 years. You'll need to remove the roller and send it in to him with a money order (he doesn't take checks or credit cards), but he'll do a fantastic job for about $40-50 per roller. Not cheap, but worth
