Because St*v* J*bs is really in the collectibles business and applies principles of planned obsolescence to make sure his computers become more valuable over time? Don't CRT filaments degrade with use? I've seen this on other workstation monitors from Sun and HP, typically ones that were used as consoles and left on 24x7. Unfortunately, for all the design that went into the NeXT, they seem to have omitted the power switch on the monitor. Also I vaguely remember, back in the days when a TV set was a big-ticket item, the local TV repairman had cylindrical devices called "boosters" that could be inserted in the circuit between the plug on the back of the CRT and the set's CRT socket to extend the life of a dim picture tube. I don't really know what it did, but I suppose it was something like a step-up transformer for the CRT filament voltage. -Frank McConnell

definition of personal computer

by maxeskin＠hotmail.com

We're talking about different things. YOu're saying that a personal computer is any computer to which the adjective personal may be applied. I mean a phrase used by various manufacturers after the mid 70's >Personal computer: Any computer owned by a single individual rather than a >corporation or government entity. Alternately any computer with a low enough >aquisition and operation cost to BE owned by an individual. This fits this >group best, since especially the mini and mainframe collectors >have such animals as their "personal computers". > >The semantics become simple. >"What is this cray 1 you have in the basement?" >"It's my personal computer." > >The fact that they're also supers, mainframes, minis, or micros becomes >irrelivant. > >:) > > >-- >Jim Strickland >jim(a)DIESPAMMERSCUMcalico.litterbox.com >----------------------------------------------------------------------- >Vote Meadocrat!

Neither the getter nor the phosphor should have anything at all to do with fading. The culprit is probably a weak cathode on the electron gun. The cathode isn't boiling off enough electrons to 'paint' the phosphor to the intensity needed. There used to be boosters available for older tv sets to goose additional life out of weak crt's. I've never heard of it in this case. Also, you can have old crt's rebuilt with new electron guns but this is VERY expensive. I would search for a replacement tube first.

PDP-11/44 boot prompt

It's too bad most micros don't have a debugger in ROM. Except for computers made by Apple, I don't know of any. I especially wish the PC had a ROM debugger.

About VCF 2.0 and system design

by franke＠sbs.de

Servus Derek, > (I may bring my Kaypro to show to > people, or perhaps just software -- there were other Kaypro demos there. > ) I may need your help in the near future. I just aquired a Kaypro 4 this weekend (just ~25 USD) - its in a bad visual state, but it seems to work (I cleand it, and it is powering up), but there where no system or application disks. So geting the system disks would be helpfull. Do you have some, ode do you know someone who does ? Thank you Gruss Hans -- Ich denke, also bin ich, also gut HRK
