Built my first computer 40 years ago
-
35 years ago, on a Work Term, there was a PDP 8 that we would play Adventure on. We dumped the source code so we could figure out how to get the last of 360 points. We had 359, but hadn't dropped the magazine at Wit's End :)
I played Adventure on PDP circa 1978 but do not remember which version. Never could cross the bridge.

Just realized that I build my first computer 40 38 years ago. A Southwest Technical Products SS50 bus system. Can't even remember which processor was in it. It was a SWTP 6800 using the Motorola MC6800 8 bit processor. I later designed and build a MC6809 CPU, with 1M memory and CRT controller, card for a University project course. Anyone else remember their stone-age computing accomplishments? Thanks for the links to the information that corrected my memory. "There are 3 things that go with age. The first is memory and I can't remember the other 2". My Mom.
I am 16 yrs old now. I started learning computer reparing when I was 10 yrs old. In the course of my work the earliest I assembled a Pentium 2 machine. Oh, yes! I also possess a 1.2GB hard disk which is in perfect running condition too! I have set it up with my old Pentium 3 machine and have installed Win98 in the hard disk.

I can't remember exactly when or why, but in the late 70's I wired some core memory by hand. Does that count? It was incredibly tedious, fiddly and boring, but it worked. Took me a couple of days... It was about the size of an SD card, plus a wooden frame to hold the wires, and it held 8 bytes! Yep. You read that right. 64 bits. That was the days when computing was for Real Men! :laugh:

I built my first computer 35 years ago, it has a CDP1802 processor and a 86 pin non-standard expansion bus. The cards in the bus slot are mostly for IO or memory expansion (4k). And the best part: It sits on my second desk and still works :)

My first computer (IIRC, a 486 bought at a yard sale) was destroyed in a garage fire. :sigh:

The first "serious" computer I put together was a IBM PC with an 8088 CPU that fell off a truck, literally. This was back in '83-'84, it was in pieces and I somehow was able to talk the owner of the company I worked for to let me have all the parts (insurance had covered the cost and he had already got the replacement). I was going to tech at the time and was on good terms with the instructors there so I was able to bring it in and worked on it there. It had no hard drive as ran off the floppies. The case was bent to heck and the boards had come loose. I put it together as best I could. I needed to tinker around with the floppy disk drive for a week or so, couldn't afford to buy a new one. I finally managed to get the PC to boot. Of course I played with it for about a month, but I ended up trading it for a ’71 Cuda. (I couldn’t make that trade these days, does anybody have a Cuda they want to trade for my computer?) :)
It was broke, so I fixed it.

I don't go back quite that far but your post made me remember a quaint story from nearly 20 years ago. My company was switching from a Nixdorf (mid-range host with dumb terminals) to a Novell network. I had nothing to do with the Nixdorf but was the "Network Manager" for the Novell. We were moving all the data (customer info, vendor info, customer orders, purchase orders, item master, stock locations / quantities, bills of material, etc...) from the Nixdorf (which was nearly 100% full) to a "modern" client/server based MRP system. We hired a Nixdorf wizard to extract all the data into comma delimited ASCII files so I could ultimately import it into the MRP system. He used a proprietary interface card to link the Nixdorf to a stand-alone PC. It took nearly 12 hours to run his export programs and write to the PC. Finally he gave me the PC with "all the data". In less than 30 minutes, I copied the files to my PC, ran them through a few conversions to prepare them for import before finally compressing them with PKZIP and copying them to a single 1.2Mb floppy!

Did said computer contribute to the fire...? :laugh:

Memories! Built my first IMSAI 8080 with model 15 teletype and paper tape storage in 76. Saw one in California during a motorcycle trip from Anchorage AK and back that summer... Then added a 10 MB 15 inch platter hard drive a year later I picked up at auction for $75.00 and 2 months of wire-wrapping the interface and writing the driver for CM/M

About 20 years ago I wired a PDP 11 to an AS400 so that we could grab ancient data. (There was a team of three of us, not a solo effort I hasten to add). It was a frustrating week, but ultimately successful.

From which machine did the ancient data originate? They're both ancient. ;P I still own a PDP-11/23 (minus disk drives, they weighed 67 pounds per drive. RL02)

That machine is newer than the Apple Macintosh. It was built in the 1990s, designed in the 1800s. But too far ahead of the precise engineering required to build.

Where I work I'm considered a dinosaur for knowing what near and far pointers are! We've been doing some work with another company and one of their guys has been really impressive. When I looked him up on linked in I saw he was writing assembly and porting a unix kernel the year I was born!

I was still using my Smoke Signal Broadcasting 6809 system (built in 1981) until about 15 years ago when I finally transferred my mailing list data files to a Windows 98 based PC using PROCOMM+ on the PC side and the type command on the SSB system :thumbsup:. I am still amazed at what I could do with a 4Mhz processor, 32Kb of static RAM and a 720Kb floppy disk drive. :cool:

I built a two-bit adder from relays a year or so ago.

1976 (or there abouts) I soldered up a veroboard mounted National Semiconductor SC/MP (scamp). 256 bytes of memory in two chips. Front panel had 8 leds, 8 switches for address and 8 switches for data. A push button for deposit and another for run. There was a single bit of output which I connected to an earpiece and it could play very simple, very short pieces of 'music', mainly stuff from my 'Learn to play the Recorder' workbook. The 'case' was made of chipboard with holes drilled in the top to allow ventilation. Front panel was a lovely piece of brushed aluminium. Consumed months of my pocket money and worth every cent. The design came from Electronics Australia and they had produced a pcb but I couldn't afford to buy it. Did anyone else make one of these?

I 'built my first computer' 24 I years ago (in my case it was more designed my first embedded system) with an SGS Thompson ST6 microcontroller ... I seem to think it ran ran at am impressive 4MHz. :-D

The first computer I worked on had a 1MB drum memory. There was only one compiler for it in the world, in California, and I was in London, the only modem in the company was the other side of the site, and I had to create punch tape to move the code form modem to computer. It was old and slow, (bit like me now) but it got into my blood and I am still coding 30 years later.

I built my first computer in 1975 using an Intel 8080. It had 1KB of ram and used LEDs and toggle switches for IO. Gradually I upgraded,it by adding tape cassette interface and hexadecimal displays with calculator style keyboard. By 1980 it had a full qwerty keyboard, a Thompson VDU chip, 64KB of dynamic ram plus 32 KB of EPROM with a Z80 and boasted my own slightly wierd version of BASIC. I still have it but I don't know if it works.

Hah! Bunch of whippersnappers! When I was vewy vewy young, I built one of these: http://www.oldcomputermuseum.com/heathkit_ec1.html[^] Standard output was to an oscilloscope. :omg: :wtf:
I was a keen used of Heathkit (as was my father!) - Had the small scope, the valve voltmeter and the DX100 AM transmitter, but I never knew about the EC1. I'd love to have one to play with now... First computer I built was the Z80 based Nascom 1 kit - about 1976 or so as I recall. Programmed it to play Lunar Lander and Star Trek, which I'd first encountered running on an Elliot 903 / ASR33 Teletype at Leeds Uni in 1973/4!
