CPT 9000

by csmith＠amdocs.com

Hi everybody, I remember somebody mentioning the CPT 9000 on this list recently. Since I just happen to be working on one, I thought I'd post this question here. Does anyone know where I can get some of the original software that might take advantage of the full screen-height? I have a copy of ventura publisher that was pre-installed, but I assume that its CPT9000 driver is corrupt. It works with the Herc ega driver, but with the CPT9000 driver, I just get some strange text-mode blocks. I also wonder whether anyone's tried Minix on it, and whether that might address the whole monitor?

I don't recall the specifics of Unibus...but its bandwidth is commonly stated as being about 7MB/sec. If that's the case, then it's unlikely that it's asynchronous. But perhaps it is asynchronous, and 7MB/sec was just the maximum. -Dave -- Dave McGuire St. Petersburg, FL

Nanoseconds per foot (RE: RIP: Betty Holberton)

by CLeyson＠aol.com

For coax or twisted pair the delay per unit length is given by:- Delay (Secs/unit length) = Root( (C/unit length)*(L/unit length) ) Example: For RG58-U coax, C=100pF/m and L=250nH/m Delay = root(250E-9*100E-12) = 5E-9 sec/m or 5ns/m A pulse will travel 66% slower in RG-58 cable than free space. If anyone needs to lay out high speed PCB's the following book is highly recommended: "High Speed Digital Design - A Handbook of Black Magic" Howard W Johnson and Martin Graham ISBN 0-13-395724-1 Chris Leyson

Both of mine have manufacture dates in 1991. Ahh, I thought the G1 came out in 1994 or so. I stand corrected. :-) -Dave -- Dave McGuire St. Petersburg, FL

Don't forget about ... *waves NetBSD flag frantically* Oh yes, most definitely...I run NetBSD in production at a number of sites, and it's wonderful. I only mentioned Linux specifically because we were specifically discussing Linux. While I like Linux a LOT, I don't consider it production-ready enough to bet my dinner on it. -Dave -- Dave McGuire St. Petersburg, FL

I never understand this- why not kick it up to 1027x768 and use the Windows Appearance controls to make the menus and screen fonts larger? That way graphics look nice and text is still readable and things you have to click on (buttons can be made bigger too) are bigger targets... It's the best of both worlds, instead of being limited to one... Regards, -dq
