Hackaday retro edition roundup

It’s time for another update chronicling the adventures and misadventures of getting really old computers to load our retro edition!

First up is [Andrew Hull] and his brilliant use of a Raspberry Pi to get an old Psion 5mx PDA on the Internet. The Raspi served as a wireless bridge, taking in Internet from a WiFi dongle and sending it back out via a serial port. Here’s a great guide for enabling PPPD on the Raspi, and giving just about anything with a serial port an Internet connection.

It may push the limits of being a retro submission, but [Glen]’s use of a modem to get on the Internet calls to us like a siren song.

Did you know Corel made computers? Well, [Victor] has one, and it’s actually a pretty interesting machine. ARM processor, an actual hard drive, and dual Ethernet ports. It was built in the late 90s and the hard drive has since died, but [Victor] booted it into Red Hat over his network and loaded up our retro site.

Finally, we come to [Greg]’s submission. He could have sent in a Mac SE/30 submission, but figured that was old hat (do you see one on there, [Greg]. No. And it’s the best computer Apple will ever make). Instead, he had an old Powerbook Duo 2300c with a Duo 230 screen lying around.

Powerbook Duos are pretty weird; they only had two ports – a single DIN-8 serial port and a dock connector. [Greg] had a Powerbook Duo dock that surprisingly had an Ethernet port. Third-party peripherals to the rescue, it seems. After plugging his Duo to his network and launching iCab, [Greg] was able to browse both the retro and main Hackaday editions. Picture Not bad for the smallest laptop Apple made before the Air.

Oh, [Greg] was also cool enough to write a tutorial for getting just about every Macintosh on the Internet. We’ve put that up on the retrocomputing guide portion of our retro site, and we’re always looking for new submissions.

You can check out the pics from all these submissions in a Web 2.0 WordPress gallery after the break, or head on over to the retro site and view them the way the gods of HTML intended.

Hackaday retro roundup, this time with a PowerPC and a PET

Thought we forgot about this, didn’t you? Well, the Hackaday Retro Edition is still going strong, and this time we have a few more retro successes that were able to load our retro site with ancient hardware.

First up is a submission by [rusbus]. He had a Power Macintosh 6100/60 lying around – the first Macintosh with a PowerPC processor instead of the Motorola 68k – and loaded up our retro site. There are some weird quirks about the 6100, notably the AAUI Ethernet tranceiver connected to a 10BASE-T network.

Although some browsers are available for the 6100, notably iCab (it’s not great, but it also works on 68k machines), [rusbus] had to settle for Internet Explorer 3.01. He eventually got it working and has a picture to prove it.

On the subject of finding a proper web browser, [azog] loaded up the retro site with a Commodore PET. There aren’t any web browsers for a PET, you say? Well, [azog] had to make one.

The network adapter is a Retroswitch Flyer Internet Modem, and after finding some network-aware projects on the Retroswitch site such as an IRC and Telnet client, [azog] put together an extremely crude web browser. In BASIC. Old BASIC. We’re impressed.

With [azog]’s browser, the PET opens up a channel to a URL, reads the text coming in, and processes it. There’s only 1kb of video RAM and 32kb of system RAM, so small luxuries like scrolling are nearly impossible. An amazing piece of work, really.

Finally, [Bob] from Portugal sent in a neat Flickr gallery of a Schneider euro XT he found in his basement. It’s based on the IBM PC/XT running an Intel 8088 processor, but is enclosed in a ‘the keyboard is the computer’ form factor reminiscent of a C64 or TRS-80. He hasn’t gotten it on the Internet yet, but it’s still a cool piece of kit.

Uncovering easter eggs in old Mac ROMs

The picture you see above is taken from the ROM of a Macintosh SE made in the  late 1980s. This black and white image remained buried inside old Macs until [Adam] and [Trammell] at NYC Resistor reverse engineered these old Mac ROMs and found a few really cool Easter eggs.

[Adam] and [Trammell] have been dumping ROMs from old computers for a while now. Their modus operandi is finding old 27C-series EPROMs on old computers, prying the out of their comfortable home, slapping them in a breadboard, and wiring up an Arduino clone to dump the data to a computer.

Recently, the guys found an old Mac SE lying on the side of a road in Brooklyn and brought it over to NYC Resistor. They had known about images hidden in the SE ROM, but the guys wanted to know how and where these pictures were stored. After carefully inspecting the binary file generated from dumping the ROM, [Adam] was able to recover three images hidden in every Macintosh SE.

The folks at Apple – especially in the heady days of the Apple II and 68k Macs – hid quite a few Easter eggs in the ROMs of their computers. For instance, the Apple IIgs has audio data stored in the ROM, and the Macintosh Classic hid an entire operating system – System 6.0.3 – in the ROM of the machine.

Hacking 14 year old Power PC Mac back to life

For a while now I have been battling a dying 2.6Ghz dual core computer, but due to laziness and budget I just let it ride. At first it would occasionally crash in games, then it got to where it would crash during routine activities. After a year of this it would nail 105 degrees C in like 20 seconds and that is where the drama starts!

I threw my 2ghz “electronics” computer into my main machine’s case and used that for a few months. It’s motherboard had suffered from every electrolytic capacitor on it being puffy, but it has worked fine for nearly 5 years. I was surprised by the sound of what ended up being 2 caps blowing off of the geforce 7600 video card. In shock and excitement I removed the blown caps, slapped her back in and got another 4 months out of it before 2 more capacitors blew and took out a voltage regulator (and who knows what else with it).

Only armed with the craptop, I was stuck in a pickle! Then a co-worker came up to me and said “hey man you want this mac I only want its zip drive”. Well of course, going bonkers without my avrgcc, datasheets, and calculators, I took on the 14 year old Apple Power Macintosh 9600/300 as my bench machine, and I will now show you how I turned it from a novelty relic to a daily useful machine after the break.

VirtualBox beta runs Mac OS X

A new beta build of VirtualBox, Sun’s Oracle’s free x86 virtualization software, makes it possible to run Mac OS X as a guest operating system…no shenanigans or flaming hoops to jump through, just pop in the $30 retail Snow Leopard upgrade disc and go. This had previously only been possible with some awkward Hackintosh-style maneuvering, or using recent editions of commercial virtualization products.

Hacking the MagSafe

magsafe
This is a simple hack that could come in handy one day. [Mooner] wanted to use a Kensington universal power supply with his Macbook Pro, but found the adapters and peripherals involved “hideous”. His solution was to wire directly to the Kensington power supply. It’s pretty simple really, only a couple resistors are needed. It’s nice to have someone else do the research for you sometimes. While his final picture does look neat and tidy, we just don’t know how much of an improvement he’s made to the aesthetics. What do you think?
