Just discovered this 1996 video debuting BeOS on their BeBox. It was way ahead of its time, especially on the DB-like FS search and multiprocessing. Nothing did what it did at that time. Demo starts 9.5 mins in. #

Andrej reshared this.

 
I came to BeOS too late to purchase the dual-CPU BeBox (it was also out of sight financially) but I own the package of BeOS for Intel CPUs
I really like their filesystem and the ability to use file metadata to form database out of filesystem. For example text file with FROM, TO, CC and Subject metadata were used for email storage.

 

Just discovered this 1996 video debuting BeOS on their BeBox. It was way ahead of its time. It had Searchlight/Cortana like searching of its file system. But the BFS filesystem had such rich metadata capabilities you could use it as a proxy to build directory services and email systems from. It's multiprocessing capabilities were unparalleled, no pun intended. Yes UNIX had that server side but this was built ground up to provide that in user space and in the display server. So this machine was able to concurrently play multiple videos, do renderings, do MIDI production all while staying responsive. Today that's just what we expect from computers. Back then it was never seen before # https://www.youtube.com/watch?v=sz3IRWM18zM

@Andrej Ditto. I remember reading the MacUser (or MacWorld) article on it back in the pre-NeXT acquisition days and starting to follow it hardcore. When I heard it was ported to x86 I was even more excited since I was no longer on the Mac platform at that time. I bought the R5 + GoBe Productive combo package when it came out. Sadly the whole thing wasn't to be :(
 

 

Great thread tearing apart an Amiga 1000, both hardware and software #
 
I just gave my Amiga 1000 away. I'm keeping the 2000, though.
 
It was pretty incredible for its time

 

From the era when we didn't have almost all of our big tech companies in one metro area... #

 

I had no idea they did this for video game motion back in the day. Love it! # #

 

The things you find on the internet...on the anniversary of Pixar shutting down their hardware division and starting to focus on making content I found this article from a former employee from the hardware days. Pretty neat #
 
Ah, I used NeWS on SGI and Sun workstations for a short time. Good thing I was good at keeping parenthesis matched up!
 
@Isaac Kuo I never used it but I always assumed it was just a Sun product until reading this. Neat that it was on other platforms as well!
 
There was a woman on g+, Kiki, who used to work for Pixar in those days and had some really great stories.

 

Putting a new SSD hard disk in a Danish mainframe from 1966 (the RC4000). Reading up on the machine it had some fascinating design stuff. I thought I was being saucy putting solid state hard disks in my classic computers lol. #
 
Just look at that beautiful wood finish.
 
@Fu ZX no, unfortunately not. I didn't check their blog (if they have one) for more details about it. Maybe can get more by contacting him.

 

How deep did they go in making Myst on the Apple II? This is brilliant! #

 

As a NeXT aficionado I always get a kick out of attempts to revitalize that UX. Thanks to Sergii Stoian's new NEXTSPACE project we are closer than ever. Side by side OPENSTEP 4.x and NEXTSPACE beta. Pretty close. # # # # github.com/trunkmaster/ne…

 
I was very sorry that etoile has died --- it was doing some really cool things with the Objective C technology (including Pragmatic Smalltalk, which looked fantastic). It also hoping it was going to solve NEXTStep's traditional anitpathy to focus-follows-mouse --- most applications just refuse to work with it at all.
 
@David Given Yeah it was putting a nice spin on GNUStep. This is based off GNUStep as well AFAIK.

 

I hope I can get my Rails server moved over to an Apple II now :) # #

 

I'm legit shocked that there is 15 GB of CP/M software binaries in aggregate. #

 

Just because I'm a glutton for punishment I'm experimenting with using the @PINE64 Pinebook Pro throttled to 408MHz setting. Surprised how snappy some things are (TeXmaker) and how glacial others are (LibreCalc). Kinda #
 
So, there's a question. What's the fastest clock speed consistent with # ? I think my first guess is 233MHz, the StrongARM-powered version of the RISC PC from Acorn, around 1996.

"The 233MHz StrongARM gave a performance improvement over the 30MHz ARM610 of more than 800%."

@hankg @PINE64
 
Yeah I think something like that could be correct if you allow for the upper end of workstation class CPUs. It's not exactly a one-for-one of course but yes.

 

I just came across Java Grinder which compiles Java code down to system executables that run on serious # gear like # 2600 # # as well. Fascinating!
 
Man, targeting the amiga is really amazing because it had all those weird coprocessors.
 
...or the Atari 2600 with 128 bytes of RAM. I'm amazed by the demo videos. For the AV for each platform they do their own things and there are severe limitations but it's still an amazing feat.

 
I'm halfway through part 1. Very good read, I didn't know much about the birth of the Atari ST other than "it was a rushed design to beat Commodore to market and be cheaper than the Amiga".

 

OK this # app (a Slack client for Win 3.1) is really neat :)

 

Wow a Twiggy Drive (the proprietary 5.25” drive from the original Lisa) Mac prototype is at auction. Only a handful were made and even fewer in existence... #retrocomputing #apple

 

I can't recall if I saw this before or not but worth sharing again even if I did. How about making your own Cray-1 using an FPGA? #retrocomputing wow.
 
I'm seeing increasing numbers of uC's implemented entirely in FPGA's, and we've started doing this at work: making VHDL representations of our new designs and trying them out in FPGA prior to the actual silicon.

 

I know the feeling :) #retrocomputing #humor https://xkcd.com/2221/

It’s sort of #retrocomputing but at the same time is a brand new 6502 based system somewhat compatible with C64. Interesting!

Isaac Kuo reshared this.

 
Completely different under the hood, but it looks a lot like a project computer I built from parts in 2014....

The Micromite Companion. It's built on the Micromite micro controller and the 8core Parallax Propeller. Programmable in MMBasic.

Wow neat! Yeah different but similar style project. Hats off on the progress!
 
To be clear..I didn't design the thing. I just built one. I was just struck by how similar they look on the surface and in what they were designed to do.
 
Here it is running a while back...

Oddly, www.pagetable.com does not resolve for me. It seems to be a problem with systemd-resolv, because it works fine with dig.

 

Some of the earliest Unix source code ever was released by @ComputerHistory last week. Cool! #retrocomputing #programming

 
It's pretty amazing what they could do with 32kb of RAM.


 

This is a pretty neat #retrocomputing project to let you quickly create some classic computer systems/games on a Pi
 
This is extreme retrogaming... 😆

Holy crap this video looks like a cool tour of #retrocomputing goodness through the Ultima series. I only played Ultima IV in any detail but the nostalgia effect is what made me decide to support @6502Workshop

 

I remember using this on the Library Macs at my university and then again years later when I went back too Mac in the Mac Cube era. Cool history #retrocomputing

 

Lightly used Vostok memory core for sale apparently... #history #space #retrocomputing
 
That said, even Soyuz didn't have an onboard computer initially, so if this was so old, it was not intended for space but for ground equipment.

The Soviets liked automation, but you can do a lot with clockwork and mechanisms, and they did.

That's a fascinating site on Soviet space computing. Thanks! :-)

I thought the computers at my high school were old! LOL Seriously though awesome they are helping to keep alive Olivetti's first mainframe (1959) #retrocomputing

Awesome, I heard about the Olivetti before but did not know it's still running

 

As someone that likes #retrocomputing and digital archaeology this sounds like a neat idea since so many of the old ones are sort of living time capsules.

 

Really neat tour of creation of UNIX pipes and how that eureka moment marks the tipping point that led to everyone thinking about the "UNIX philosophy" #history #retrocomputing #unix
 
FTA: "...He didn’t do exactly what I had proposed for the pipe system call; he invented a slightly better one..."

That right there sums up what excellent teams do.
 
@Richard Healy Amen to that! I thought the exact some thing when I read it!
 
Once I started getting the idea of functional programming, I came upon an article that I thought was fascinating about how pipes implement a call structure that's very similar to what you use in FP, except you have to think of it in postfix terms, rather than prefix terms: Rather than data flowing from right to left, it flows from left to right, with the output of the command from the left becoming the input to the command on its right.

I've tried looking for the article, because the idea of integrating a language into an operating system context (á la Smalltalk) intrigued me, and I've wanted to tell people who are interested in FP or Linux about it, but I've been unable to find it again. :(

 

 
@smellsofbikes@pluspora.com - Is there still a running one, perhaps at the converted MacDonalds at NASA Ames? (You know about the converted Micky-D where they collect old gear and try to recover lost data?) Anyway, I had the good fortune to work with one of the people who used that computer in real life.
 
The team Ken Shirriff works with restored one that never flew. Below is a link to his write up of getting a Bitcoin mining hash algorithm working on it just to say they did. They have several virtual ones so people can experiment with it on their own without an actual physical article. It's pretty impressive amount of computer archeology and restoration. http://www.righto.com/2019/07/bitcoin-mining-on-apollo-guidance.html

 

Use the Apollo computer to mine bitcoin? Technically yes but at 1 hash every 10 seconds, no. Fascinating coverage of how to develop for it though! #retrocomputing #space
 
The conclusion nicely puts the power of the AGC into its period context. Not a bad machine for its day given that they required it to be small light and rad-hardened.
 
@Stephen Gunnell Yeah as they said it was relatively underpowered at 40K add operations per second compared to other computers of the day but other computers of the day were also far more massive. It's pretty amazing how well it performed against microcomputers 10-15 years later. I found this article on benchmarks from 1977. Looking at the integer add test Microsoft's BASIC took 10 seconds to do 1000 additions. At 40 KIPS the AGC would have done it in 0.0125 seconds. If we say that the comparison took up as much time as the addition and the BASIC interpreter is 10x slower than the same routine written in assembly language then we'd still be looking at the AGC being 10x faster. This makes me want to rerun these benchmarks and write them in 6502 Assembly as a comparison lol.

 

I have seen reports on the nature of the errors (basically computer was asked to compute more than it had capacity for) but not the why or the fail-over modes if the condition persisted. Great article #space #retrocomputing

Reading about the early days of id Software when they basically cocooned themselves in a two floor apartment one Wisconsin winter cranking out Wolfentein 3D hits that nostalgic chord in me that has done that and still likes doing that sort of thing when the right passion project comes along. There is just something to being so focused on cranking out software you find interesting. It's a neat read either way. #retrocomputing https://www.gamasutra.com/view/news/344672/How_id_built_Wolfenstein_3D_using_Commander_Keen_tech.php?fbclid=IwAR0PUrAf2i06-TTY6dub12V86AIKxJ3gAl8pMYmt111UKgFNmreYoc8pZnU

 
There's at least one in the "Cave" where we have several work benches and a couple racks clustered together like cubicle, and another one or two attached to various machines and pushed aside as spares in the lab. The guy nearest me at work uses one or two for his primary workstations much like I use Bluetooth ones for my laptops.

On the flip side last time we cleaned up, all the three button (no wheeled) mice got tossed, there was like a box full.
 
I have always preferred trackballs but they are sometimes hard to find. The first trackball I used back in the mid 80's had a ball 2 or more inches in diameter and had a fair bit of momentum. You could flick it with your thumb and it would take the cursor all the way up the page. The device was a Mergenthaler Linotype badged page layout terminal.

I've looked at attending VCE. Thanks for the forum recommendation though!

 

#retrocomputing moment of the day. A ~7 minute marketing video on the massively parallel Thinking Machines CM-2 from back in the late-80s. 64K processors in 1988 w/28GFLOPS peak. Wow. https://youtu.be/BVtHh9JoS3s

Talk about #retrocomputing! I downloaded but didn't read it so I don't which version of Linux runs on it yet... ;)
