My New Desk Top Computer

[JDgreen227]

Last Gateway I purchased was their premium model that used Windows 98...and it still works great...lol.

Love Dell for desktops, current one is a modded 530 with many, many upgrades (Vista 64 bit)and an Asus 24 inch monitor, machine is going on 3 1/2 years old now, has never given me any problems. Modded the Dell 4700 I purchased for my wife back in 2004 (!!!) XP, bigger power supply, 4 GB ram, 320 gb HD, 1 GB video card, has the same Asus 24 inch monitor, has never given us any problems either. Both still have nothing but OEM cooling, I always wonder why people say their desktops are troublesome. Maybe I have just been lucky?

Having been in the computer service business for over 30 years, I can tell you that there are reasonably safe ways to securely erase the data on your computer hard drive. It is done all the time with very good results.

There are free and commercial applications, I tend to use the free one for home use.

DBAN - Darik's Boot and Nuke. You can download the image, burn a CD (most computers will boot from CD nowadays). When you boot from the CD, it has a menu to select from. You select the disk you want to erase and the method. The DoD often uses 5220M (I think that is right), 3 pass is fine for most of us, 7 pass is better. Darik's Boot And Nuke | Hard Drive Disk Wipe and Data Clearing

Another free one for Windows systems is eraser. Eraser :: Downloads

Another (if your hardware supports it) is the erase program from UCSD.
CMRR - Secure Erase

If you are really paranoid, you can set up an encrypted file system to store your data on (just a portion of your harddrive). Truecrypt is one that I use for home. TrueCrypt - Free Open-Source On-The-Fly Disk Encryption Software for Windows 7/Vista/XP, Mac OS X and Linux

If you want to use commercial software, Blannco has some products that work also. Data Erasure - Secure Data Destruction - Erase Data - Blancco Software

The important thing is, do not just give/throw/sell your old computer without taking care of your personal data that might be on it.

A 3/8 drill bit to the hard drive in a couple spots might work?

Jim - you are feeling old...The first computer I bough my son was a Sinclair...remember that one ? It plugged into the TV...he did some of his math homework on it and played some games( he was 10 yrs, old )

Brin, I bought one of those Timex-Sinclair TS-1000 computers with the 16k memory pack that plugged into the back of the circuit board. Unfortunately, the computer was made so cheaply that the pins for that add-on were solder coated instead of gold. Any vibration made the memory module lose contact for a millisecond and the computer crashed. I remember programming in basic and waiting 15 minutes for programs to load or save to the cassette tape drive.

The first "real" computer was an IBM PCjr I bought for my kids with a color monitor and Epson JX-80 color dot matrix printer. That set me back around $4500 dollars. I had word processing software on it and spreadsheet software that came bundled with the computer, but all my ex-wife ever let them do with it was play games. I was really miffed because it was a fine little computer system.

When I was working at the University of Texas at Dallas in the Geosciences Department, they had Osborne portable computers with 40 column screens. Then they added on 80 column cards that worked by scrolling the screen left and right to see the whole line of text. It was a hoot, but with built-in Wordstar, they were word processing powerhouses. Can you imagine typing a Doctoral Thesis on a mainframe terminal using a line editor? That's what they used before getting the Osbornes.

Many of the Android based tablets you can do that right now. HDMI cable for the monitor, and Bluetooth for the keyboard and mouse. Actually, I use a Bluetooth keyboard on my Android cell phone when I'm using it out in the shop. I can hook a monitor to it, but I haven't tried that yet. Works great if I want to type up a longer email or if I'm inventorying new purchases.

Even this is from my cell phone.

Bluetooth keyboard/mouse? Interesting.

A tablet is bigger than I would want at this point. I love the Ipod touch and what it can do but am not the type to keep upgrading when the latest model comes out. I typically buy this type of thing used. My HP desktop I bought used in the summer, dual core processor and it screams with a fresh XP image. The kids use our old Dell that's 7 or 8 years old and it was a refurb. The electronics are getting pretty amazing but my wallet won't allow too much for upgrades at this point.

Gizmo, did you ever learn the boot program sequence for the Univac 1218/1219 computers? As you and I discussed the MK152 computer earlier, it was a Univac 1219 with 32k of iron core memory. The OP program was loaded from open reel magnetic tape, but to get the computer to load the tape, it had to have the "loader program" input from paper tape. Before the loader program could be loaded, you had to load the bootstrap program into memory from the front registers in octal code. Every computer technician I knew had that bootstrap program memorized. Actually, the computer had the bootstrap code in non-volatile memory as I remember. Entering by hand was a backup method. Our output device was a teletype printer. How many people today know what ASCII code is or what A-S-C-I-I stands for?

All of a sudden, I'm feeling very old. . .

You are old,,,,, Like me! Let's thank God.
We loaded off of mylar punch tape.
I am sure I had to learn the boot program but don't recall it. I do remember loading a small tape sometimes before the OP.

Yo jinman,
After a program load and letting one rip.

 

[RobertN]

After years around high tech, more working on failure analysis of microprocessor and eeprom then flash memory, I usually build my own.

It can be hard to start from fresh, and match prices of the bundles available out there.

I spent years at Intel; I tend to stick with their processors and boards. In-Win has some chassis that have good thermals and acoustics. There are nice 80+ Bronze and Gold power supplies out there that give good energy performance.

I came in late; first computer I ever worked with was a Vax 11-780. End user, not admin.

My first computer was a Tandy 2000 from Radioshack. It didn't have a hard drive; only two disk drives. One for the application and one for the data files. It had the old "green screen" monitor - no graphics. The printer was the size of a large microwave oven and was so loud that when you hit "print" it was best to leave the room. It used a rollerball head like the IBM Selectric typewritter. I used it mainly for word processing (early Wordperfect, I think). It did have some games such as Pirate, but without graphics you had to type each direction line by line. If you got fustrated and typed in a curse word, it warned you not to use such language. I found out that it had a fairly large vocabulary of curse words. I paid about $2,500 for it.

Jinman my first computer was a TI 99 with 16k of memory and a television for a moniter. by the way ASCII stands for American Standard Code for Information Interchange, and that is from memory not looked up. I have spent many an hour behind a Digital Decwriter 300 buad termiinal. And I can remember some of the ASCII charaters, numbers like space is 32 and A is 65 I think so I guess B would be 66 and so on. I think the escape sequence was ascii 127. but I am not sure of that. We also used a small thermal terminal made by Texas Instruments called a "silent 700". It was not really silent, but it did not make a lot of noise, and no where near as much as a dec-writer. Sure brings back some memories. Oh I also had a complete Teletype set at one time I used for a while, a Teletype model 15, with typing reperferator and the Transmitter Distributer (TD). of course these machines were from the 1920's and all run in a 20ma loop in series, and used a 5 level code called baudot not a 7 level or 8 level code like ASCII. I had a lot of paper tapes of "teletype pictures" and such things. So in rambling on, here I think I have owned and used some of the oldest "iron" on here.

Dell is still a good computer. I have a bunch of computers in the house, and everyone uses my I7 Dell cause it rocks.

Robert,

I worked at Intel in Oregon, and out in sales in sourthern California from 1991 to 2002.

I still have a grunch of shares from the employee stock plan that are STILL under water from those days...

Be well sir,

James,
Ya beat me!

In 1983 or 84 (I was in the Navy) I bought a Commodore 64, with a 5.25" FLOPPY and a printer. Mostly for Jumpman.

But I also wrote my case for Navy Legal to justify my keeping custody of my 5 week old twin sons vs. letting my cheating wife (soon to be ex) keep them on the crappy word processor and dot matrix printer.

After I got out in 1986 I got my hands on an old early Compaq luggable (the suitcase sized one) that had a 10 meg HDD! and a 5.25 floppy (I used the punch so I could format and write to BOTH SIDES!). When the gree screen internal to the unit died, I managed to rig up a connection to an external amber 12' monitor, but it no longer lugged... I used an early form of word perfect...

After that it was a 386/dx25! then I homebuilt a system with a free 487 Intel gave one to each employee (so this was 91/92 ish) then fuggedabowit, I've had so many systems it just does not matter.

I believe there are 4-5 laptops (they all will still boot) and at least 3-4 desktops somewhere in the house... That is just mine, not counting the one work gives me.

Be well,
David

"GRUNCH of shares"...was that an intentional typo....:laughing:

 

[g0rd0]

my first comuter,,,a radio shack" rainbowII "? It was so long ago that I am not sure if that is the actual name of it. It did not have a floppy only a tape (casset) drive. My brother in law then gave me a coleco machine, had it for years, playing donky kong, lady bug and all sorts of other mindless games:laughing:.
Then I went to a hp preserio desktop with xp in it LOVED it. 7 years latter it finnally died . I now have an Acer on the desk and a hp laptop both with windows 7, 3 cores and more memory than either of us will use.

A lot of you guys know how to build/maintain/program/repair computer and I only know how to use'em.:laughing:

And all this talk about older computers always reminds of when the City of Dallas got 2 IBM 360s and thought that would be all the computer the City would ever need in any of our lifetimes.

Yeah, I know and have done all that stuff but I don't want to do it any more. All I want to do is use them. I keep telling myself "this is the last computer I will ever buy". Just like I keep saying "that was the last attachment I will ever buy for the tractor", 2008 we bought a new tractor:confused2:

My first IBM machine I paid 2500 for Used!. The stupid thing sold new for about 5000 bucks or so. It had 256K of RAM and 2 360K floppys, No HD. I expanded it with an AST Sixpack card to 640K (one row of chips at a time) you bought the chips and plugged them in yourself as you could afford them. I also put in an 8087 math co-processor and it really made my satellite prediction program fly. Later I scrimped and saved and purchased a used 20Meg hard drive, and put all the programs and data I owned at the time on it, and had room left over:laughing:. I finally sold it and purchased a 386 DX 40 motherboard, and built up a computer that was 10 times faster than the old 8088 IBM machine. At the time I could not imagine anything faster. The my bubble was burst when the 486 machines came out..and it did not take long:laughing: Of course I remember the old luggables and how coveted they were at the time. before the DOS machines they run on CPM and used word processing programs like WordStar. CPM (Control Program for Microcomputers) was a dos-like forerunner, that I think was developed by DEC. The old Model 15 Teletype system I referenced earlier was used for decades in newsrooms and later the ones I got were surplus from the Frisco Railroad. I used them to communicate over Radio by building up a simple Phase Locked Loop radio modem that takes audio from the radio and decodes the two tones (mark and space) and drive the old mechanical selector magnets on the Teletype machine. The Teletype machines had thousands of parts driven by a large camshaft from a synch. motor. It was a mechanical marvel from another era. Grandpa, may not have had many electronic computers, but our ancestors sure could make some intricate machines.

Bird, I have a paperbound, large format book titled "Digital Retro" by Gordon Laing. Subtitled "The evolution and design of the personal computer". Lavishly illustrated and quite detailed. It labels the early video games like the Atari 2600 and Coelco Vision consoles as computers, although I never would have thought of them as such.
