Macintosh 128k with mods by Julian Systems

[kahlil88]

I was just given an original Macintosh with some neat mods. There's a case fan and a couple boards made by Julian Systems - one is clearly labeled "ROM & SCSI" and I'm guessing the other is RAM expansion (both dated 1986). Couldn't find much info about the company but there was a mention of such an upgrade in an Oct 1986 Mac World.

I’ve seen those strange screen covers before. What are they, and what is their purpose? Can’t be anti-glare; from pictures I’ve seen they are far more reflective than the actual screen.

Typically a privacy cover, so the screen is only visible from directly in front of the computer.

Ah, interesting. I suppose the previous owners of these must have been government workers.

Or perhaps they worked either at an accounting, bank, investment or law firm, or at some other, related industry where privacy is important.

Indeed. I mean at my work now we're recommended to get privacy film for our laptop screens if we're working with personal information and work in situations where someone might be looking (on a plane or train for example), and I'm not remotely government-affiliated. Fortunately I don't have to deal with personal information in my job, it would make me very neurotic.

I was being facetious… Spending taxpayer money on frivolous things that don’t really serve a purpose. I get the need for privacy in some situations, but I can still see that screen just fine in the angle shot.

i don't understand, please explain

The point isn't to totally make the screen invisible except from 90 degrees dead on; that would also have bad ergonomic effects on the user. The point is to make it harder for someone to look without being so obvious about it they get caught.

I think you might need to work on the way you think about risk analysis.

My comment about government workers was an intended joke about the apparent inherent need of government officials to spend money on useless and trivial things. Apparently I missed the mark.

Thanks for your (unsolicited) suggestion, but I don’t “need” to do anything.

Then your decisions will continue to be poor. Thanks.

i still don't understand what you mean. my government officials spend money on a lot of useful stuff like roads and clean water!
maybe you have a bad government??

Those were very common back in the '90's, particularly in the cubicle environment that was prevalent then.
It kept people from walking by and seeing that you were really playing solitaire instead of working.

They're still popular at banks and other financial institutions. Every LCD I've seen has a privacy filter. Although at my local bank they all face towards a large window next to the drive-up ATM. I looked, and you can see all the screens. Not very well thought out on their part.

I've got a few of theses. Some were indeed privacy filters

The other type was a filter supposed to reduce eye fatigue similar to what theses yellow glasses do today with LCDs. It worked somewhat well, at least on screens where low refresh rate was an issue (< 75 Hz for me)

Some had additional ground connectivity to remove static electricity as well, so no more air moving while looking to close to the screen

Geez! Give the guy a break here. Nothing he said was offensive.
