Old Laptops, Modems, And The Hackaday Retro Edition

We haven’t been getting very many submissions of extremely old computers loading up the Hackaday Retro Edition in a while. For shame. Thankfully, [alnwlsn] is here to pick up the slack from the rest of you with his latest accomplishment, getting two old laptops on the Internet with some old telecom equipment.

The first is a Toshiba from about 1995, Pentium processor, 12 MB of RAM, and a 10 GB (!) hard drive. [aln] had a PCMICA modem sitting around, and with Windows 95 and IE 5.5, he was able to slowly connect.

Pentium class machines are okay, but the next one – a Zenith Data Systems laptop from about 1987 – is awesome. 80C88 CPU, two 720k floppy drives, and the exact amount of RAM in that quote falsely attributed to [Bill Gates]. [alnwlsn] is connecting with a 28.8k modem, but the serial port only supports up to 9600. It’s a computer so old, even the retro edition’s main page times out. The about page, though, loaded fine.

[alnwlsn] used a modem with both of these laptops, but he doesn’t have dial-up or even a landline. This forced him to make his own line simulator that requires plugging in the phone line at the right time, manually ringing a modem connected to another computer, and letting PPP take it from there. It’s a crude circuit, but it works. slow, but it works. Video below.

Hackaday Retro Edition: Hackadaying At 300 Baud

SONY DSC

For a bottom of the barrel website like our retro edition, there’s little reason to have a fast Internet connection. Even the fastest hands in the land can barely type faster than 300 baud. The problem with low-speed connections is the overhead involved, as [Pierre] discovered when he dug out an acoustic modem from the ’80s and loaded up our retro site.

While this isn’t the first modem ever made – that’s 1960s tech – but it does operate at the same speed – 300 bits per second, or slower than you reading this sentence. [Pierre] stuck a desk phone into the modem’s cups, plugged it in to a phone line simulator, and connected to a Raspberry Pi equipped with another modem. From there, it was pretty easy to set up a terminal at 300 baud.

A serial connection isn’t a connection to the Internet, however, and at 300 baud, PPP is nearly impossible. The overhead of encapsulating packets is just that high. SLIP is a much better choice to send IP packets over a slow serial connection, but [Pierre]‘s mac doesn’t include the proper tools.

[Pierre] ended up using the serial connection between his Mac and Raspi with Zterm. From there, Lynx and Bob’s your uncle.

There’s an unsurprisingly long video of [Pierre] loading up the retro site below, as well an unsurprisingly long video of speedtest.net running at 56k.

Hackaday Retro Edition: Parallel Port Ethernet

It’s time once again for a roundup of ancient hardware that has successfully loaded our retro edition. Up this time is a completely random and totally not planned roundup of parallel port to Ethernet adapters.


First up is [Tom Moss] with his IBM 5150 – the first ‘IBM Compatible’ home computer, progenitor of the i7 boxxen warming your ankles as you read this. This machine comes standard with a 4.77 MHz 8088 CPU, 8087 FPU, 512k RAM, two 360k 5.25″ floppy drives, and a few very cool additions: an ISA to CompactFlash card adapter, giving [Tom]‘s box 4GB of storage.

How is [Tom] connecting to the Internet? A Xircom PE3-10BT Network Adapter. This neat device turns any parallel port into an Ethernet. With a Telnet program, [Tom] was able to connect to a Unix system and use Lynx to browse over to the retro site. He’s yet to get a DOS browser working, but FTP is go, allowing him to download ancient software directly onto his huge CF card.

The next one isn’t exactly vintage, but it does carry the spirit of antiquated hardware onto the web. [Valentin] is using a FleaFPGA and a 186 over at OpenCores. The FPGA board gives him VGA output, an SD card, A PS/2 keyboard, but no options for networking. That’s no problem for [Valentin], as he wired up a Xircom PE3 parallel port to Ethernet adapter. Yes, the same adapter as the 5150 above. [Valentin] says his parallel port hack is a bit of a mess with non-bidirectional and no dedicated IRQ hardware support. It works, though, so we can’t fault him for that.

We’re always looking for people who have loaded our retro edition on old hardware. If you have some outdated hardware sitting in the attic, get it out, load up Hackaday Retro, and send it in.

Hack A Day Goes Retro in a Computer Museum

vt100_HAD Our friends over at Hack42 in the Netherlands decided to have some fun with their computer museum. So far, they’ve been able to display the Hack a Day retro site on three classic computers — including an Apple Lisa, a DEC GIGI, and a run of the mill DEC VT100. We had the opportunity to visit Hack42 last October during our Hackerspacing in Europe trip — but just as a refresher if you don’t remember, Hack42 is in Arnhem, in the Netherlands — just outside of Germany. The compound was built in 1942 as a German military base, disguised as a bunch of farmhouses. It is now home to Hack42, artist studios, and other random businesses. The neat thing is, its location is still blurred out on Google Maps! Needless to say, their hackerspace has lots of space. Seriously. So much so they have their own computer museum! Which is why they’ve decided to have some fun with them… [Read more...]

Hackaday Retro Edition: AppleTalk

retro

If you do a survey of what makes and models of classic computers manage to pull off a Retro Success by loading our Web 1.0 retro site, you’ll notice a disproportionate number of classic Macintosh computers, the cute, small all-in-one boxes with a nine-inch black or white screen. Part of this is the nigh indestructible nature of these boxes, and part of this is the networking built into every classic Mac – AppleTalk.

The physical connections for AppleTalk is just a small breakout box with two Mini-DIN connectors (or RJ11 phone jacks for PhoneNet) attached to one of the serial ports on the Mac. This isn’t just a null modem connection, though. An AppleTalk network can support up to 32 nodes, file transfer, networked printers, and in later updates booting an Apple IIGS from a networked drive. Whenever you have a few classic Macs in one room, an AppleTalk network is bound to appear at some point, especially considering the limitations of an 800kB disk drive for sneakernetting and the fact the AppleTalk software is supplied with every version of the operating system.

[Chris] had an old dual disk Macintosh SE he had brought back from the dead, but his modern expectations of Internet On Every Computer meant this cute little compy was severely lacking. Yes, SCSI to Ethernet adapters exist, but they’re surprisingly expensive. Modems are right out because of landlines. How did he solve this problem? With AppleTalk, of course.

After picking up a pair of PhoneNet adapters, [Chris] plugged one into a PowerPC mac running OS 9. MacTCP, the Apple TCP/IP control panel for classic Mac operating systems, is able to encapsulate IP traffic into AppleTalk Packets. After turning the PowerPC mac into a router, [Chris] managed to get his all-in-one SE on the internet.

The only problem with this setup is the browser. NCSA Mosaic doesn’t have the ability to send traffic to a proxy server, but another classic Mac browser, MacWeb 2.0c does. This allowed him to load up our retro site using forgotten and long unsupported technologies.


If you have an old computer sitting around, try to load our retro site with it. Take a few pictures, and we’ll put it up in one of our Retro Roundups

Hackaday 68k: A New Hackaday Project

68000 It’s no secret Hackaday loves retrocomputers, classic hardware, and vintage tech. Now that we have a great way to present long-form projects, it only makes sense that we combine our loves with a new build. Over the next few months, I’ll be developing a homebrew computer based on the Motorola 68000 CPU, documenting everything along the way, and building a very capable piece of hardware that will end up hosting a few Hackaday webpages. I already have a solid start on the project and will be posting on our front page to discuss the major parts already in progress, and those yet to come.

There are a few reasons we’re taking on this project. With few exceptions, most of the homebrew projects we see are based around 8-bit micros – specifically the 6502 and Z80. 16 and 32-bit CPUs really aren’t that much more difficult to work with, and if we can spearhead a renaissance of the 68k, 65816, or even a 386 (!), we’re all for that. Also, it’s been suggested that we host the Hackaday Retro site on retro hardware, and what better way to do that by documenting a build on our new project hosting site?

That’s a very brief introduction to this project. Let’s take a closer look at what hardware we’ll be using, what software we’ll get running, and what you can do to help.

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.
