RasPi Powered ADM-3A Dumb Terminal

ADM3A

[Andrew Curtin] tipped us off to another excellent resurrected vintage one piece ADM-3A dumb terminal. [Andrew] not only resurrected this sexy machine by breathing life into her once more after 37 years but he also got it connected online to retro.hackaday.com for those coveted retro Super Nerd bonus points.

As with other ADM-3A terminals we have seen on Hackaday, the terminal screen can be interfaced over an RS-232 serial connector to a laptop, however, [Andrew] didn’t have a laptop to sacrifice so he utilized the now popular laptop stand-in RasPi. It’s a clever form factor solution which makes it appear more like a standalone computer for the first time in its life.

To make the hack work he needed a serial adapter to link the ADM-3A terminal to the Ras-PI so he constructed one for himself. It’s another clever solution but he didn’t share much information on this build. Maybe he’ll comment below or elaborate on his site with more details on the construction and utilization of the adapter board from the Ras-PI so others could easily repeat this fun hack.

Hackaday Retro Edition: Retro Roundup

retro

We’ve rebooted the Hackaday Retro Edition and again we’re getting a few submissions for retro successes – old computers that somehow managed to load our crappy, pure-HTML, no-javascript edition.


Inspired by the Palm Lifedrive in the previous retro roundup, [Bobby] dug out his Palm TX and loaded up the retro edition with the Blazer browser. Given this device has WiFi and a browser, it’s not much, but [Bobby] did run in to a bit of a problem: Palm never released WPA2 for personal use, and this device’s WPA abilities are buried away in a server somewhere. Interesting that a device that’s relatively young could run into problems so easily.

How about another Palm? [nezb]‘s first smartphone, back in 2003, was a Treo 600. He dug it out, got it activated (no WiFi), and was able to load the retro edition. Even the Palm-optimized edition of Slashdot works!

How about some Xenix action? [Lorenzo] had an Olivetti 386 box with 4MB of RAM with Xenix – Microsoft Unix – as the operating system. The connection was over Ethernet using a thinnet card. Here’s a video of it booting.

[Eugenio] sent in a twofer. The first is a Thinkpad 600, a neat little laptop that would make for a great portable DOS gaming rig. It’s running Mandrake Linux 9, his very first Linux. Next up is the venerable Mac SE/30 with a Kinetics Etherport network card. It’s using a telnet client to talk to a Debian box.

Here’s one that was cool enough for its own post: [Hudson] over at NYC Resistor salvaged an old Mac SE with a BeagleBone Black connected to the CRT. This effectively turns the SE into a modern (if low powered) ARM Linux box. Emulators are always an option, though, as is loading our retro edition in xterm.

Links to the pics below, and you’re always welcome to dust off your old boxxen, fire it up, and load up the retro edition. It’s new and improved! Every half hour or so, five classic hacks from the first 10,000 Hackaday posts are converted to pure HTML. Take a pic and send it in.

Hackaday retro edition roundup

Retro

The Hackaday retro edition hasn’t been updated in a while, and for that I am very sorry. Still, digging through my email reveals quite a lot of very cool retro computers that were able to load the retro edition over the Internet, and it would be a terrible shame to let these awesome submissions die in my inbox. Without further adieu, here are the best retro computers that have been sent in over the last few months:

[Scott] got his Mac SE to load up the retro edition. This was a chore; after getting a serial connection from his SE to the outside world, [Scott] realized he didn’t have a browser on his retro mac. 800k drives are a pain, it seems. He eventually got everything running in a terminal session, and the retro edition loaded beautifully.

How about another Mac? This one is [Raymond]‘s Mac II, the first not-all-in-one Macintosh. NuBus Ethernet card, Netscape 2.02, and 26 years of history behind this machine.

Here’s a weird one: it’s a Siemens interactive display originally used for a building management display. It has a 10 inch touch screen display at 640×480 resolution and runs Windows CE 5.0. After fiddling with some files, [Nick] managed to get the networking running on this machine and tried to load Google. Anyone who has played around with the class of machines we seen for retro submissions knows what happened next (nothing), but luckily [Nick] remembered Hackaday has a retro site. The rest is history.

[Kyle] has a really cool box on his hands. It’s a Compaq 486SX overclocked from 25MHz to 33MHz. 20 Megabytes of RAM, network card, and a Soundblaster 16 make this computer from 1993 a very respectable box for old DOS gaming. It can also browse the web with Arachne.

Finally, [cnlohr], the guy who made his own electron microscope  never mind, he’s still awesome and can manufacture glass PCBs at home, found an old green screen CRT while cleaning out a friend’s place. He hooked it up to one of his glass PCB AVR microcontroller things and did the usual text terminal fare; ASCII Star Wars with telnet and using lynx to load up the retro site. It’s only a 48-column display, but the retro edition is surprisingly readable. Very cool.

Converting an IBM PCjr joystick to USB

pcjr-joystick-usb-conversion

Seeing this IBM joystick again really brings back memories. But it can be used on a modern system thanks to this USB conversion project.

This particular model had a connector which is foreign to us. It looks like a boxy USB-A plug, but has an eight-pin sockets which looks like it’s 0.1″ pitch. You could try to make your own male connector using a dual-row pin header, but [Gruso] just went ahead and lopped off the end of the cable. He managed to dig up the pin-out for the device and found that it could be wired up to a gameport — the connector being the only real difference. He gutted a USB gameport adapter, removing the DB15 connector and soldering directly to the board. The boxy old peripheral has just enough room to house that PCB.

If you’re looking for a few more details than this build album provides check out [Gruso's] comments in the Reddit thread.

Hackaday Retro Roundup: Ultraportables edition

front

A few months ago, we rolled out an updated Hackaday, a badly needed new layout replacing the HTML and CSS that had remained unchanged since 2004. Of course a few people didn’t like change and complained about slow load times. We’ve experienced a slightly slower load time as well, so we’ll just wait until the year 2020 when our computers are many times faster and our Internet is provided by Google Fiber. Until then, our pokey battlestations and vintage computers can still check out a few classic hacks on our retro site. Here’s a few retro successes – Hackaday readers who pulled out their old tech and loaded up the retro site – that have come in over the past weeks and months.

Hackaday Retro edition: The Macintosh SE/30

In 1988, Apple introduced the Macintosh IIx, an upgrade of the Mac II that included a Motorola 68030 CPU. The IIcx – a compact version of the IIx, also with a 68030 – was introduced in 1989. That same year, product designers at Apple created a more powerful version of the all-in-one Macintosh SE using the same CPU found in the IIx and IIcx. Unfortunately, the naming convention didn’t hold but the Macintosh SE/30 is still the greatest computer Apple will ever build.

Earlier this month, [Greg] sent in a submission for our retro edition successes. A huge mac fan, [Greg] connected his Powerbook Duo to an Ethernet adapter and loaded up our retro edition. [Greg] is back again, this time with an SE/30.

In the three pictures [Greg] sent us (in the gallery after the break), you can see his extremely clean SE/30 booting into System 7 and loading up our retro site. In the third picture, you can see [Greg] playing Bolo, one of the first network-enabled games ever made, and still a very fun waste of time today.

If you’re wondering what makes the SE/30 so great, consider this: the SE/30 is able to address up to 128 MB of RAM. Keep in mind this computer is from an era when one or two Megabytes of RAM would be more than enough to get just about any job done. The SE/30 also made a fabulous server. Even today it would be a capable home media server if it weren’t for its relatively slow networking capabilities and 2 Gigabyte file size (not volume size) limit.

[Greg] has a very cool machine on his hands here, and we’re pleased as punch his SE/30 could make its way over to our retro site.

Hackaday retro edition roundup

In case you’ve forgotten about it, we still have a retro edition of Hackaday. It’s our simple, hand-coded HTML site featuring a few random hacks from Hackaday’s 8-year history. There’s also a retro successes page where our readers can log on with their old boxxen and claim their prize as a master of retrocomputing. Here’s a few retro successes that came in over the past month or so:

Our second OS/2 Warp submission comes from [Chris]. He got an HP Omnibook 800CT running OS/2 Warp 4 to load up our retro site.

A few of you may be wondering what the upper bound of what we consider a retro computer is. [Witek] used a Wyse thin client from the year 2000 to pull up our retro edition. These terrible computers used a Compact Flash card plugged directly into an IDE port to load up Windows CE. Yeah, it’s technically a SSD. [Witek] put the GRUB bootloader on one and loaded up our retro edition with Debian Squeeze. We have too many bad memories of these thin clients, and we’ve got to commend [Witek] for putting the effort into doing something useful with one.

[leadacid] is on a roll. He gave us our first OS/2 Warp submission and has since moved onto an IBM RS/6000. Previously, he got a Macintosh 8100 and a Quadra 840AV to pull up the retro site. Nice job.

Those are all the retro submissions for now, but if you have an old computer lying around, try pulling up our retro site and send it in.
