Tiny ’90s Laptop Gets Modern Power

August 21, 2024 by 19 Comments

The laptop to have here in the 2020s varies depending on who you ask, perhaps a Framework, or maybe a ThinkPad. Back in the 1990s the answer might have included a now-forgotten contender, because in that decade Toshiba made a range of legendarily tough chunky grey machines. Of these the smallest was the Libretto, a paperback book sized clamshell design which was an object of desire. It’s one of these that [Robert’s Retro] has upgraded to use USB-C power instead of the original power brick.

The full video is below the break, and while it first deals with replacing a defective screen, the power part starts just before 22 minutes in. As you’d expect it involves a USP-C PD trigger board, this time at 15 volts. It’s mounted in a small 3D printed adapter to fill the space of the original jack, and requires a tiny notch be removed from the corner of its PCB to fit round the motherboard. The rest of the video deals with reassembling the machine and tending to mishaps with the ageing plastic, but the result is a Libretto with a modern charging port.

Naturally a machine with a Pentium CPU and 32 megabytes of RAM is in of limited use in modern terms, but these Librettos remain very well-designed tiny PCs to this day. It’s great to see them still being modified and upgraded, even if perhaps there’s a limit to how far you can push their computing power. We’ve encountered the Libretto before a few times, such as when one was used to retrieve data from an old Flash card.

PCMCIA Flash Card Gives Up Its Secrets Thanks To Retro Gear

July 18, 2023 by 27 Comments

There are two ways to recover data from an obsolete storage medium. One way is to pull out all the tools in the hacker’s kit — with logic analyzers, oscilloscopes, and bit-banged software in a desperate attempt to reverse engineer the original protocol. The other way is to have a really, really deep junk bin that just happens to contain exactly the right pieces that would have been used decades ago.

For recovering data from a 25-year-old PCMCIA memory card, [Dave] from Vintage Apparatus chose the latter method. But to be fair, characterizing the stash of gear he had to select from as a “junk bin” is pretty insulting. It’s more like a museum of retro technology, which just so happened to hold  Toshiba Libretto, a subnotebook computer hailing from the late 1990s. The machine sports a pair of PCMCIA slots and was just the thing to read the data from the old 32 MB SanDisk flash card, which once lived in a backpack-mounted GPS system for surveyors.

If this hack sounds as easy as plugging things into an old computer, you’d be right — if you just happen to have a stack of floppies containing the Windows 98 drivers for said things. So [Dave]’s task became a game of finding the right combination of cards that already had the drivers installed and would provide the connectivity needed to get the data off the flash card. Between a suspiciously crunchy-sounding floppy drive and an Ethernet card dongle badly in need of some contact cleaner, cobbling together the right hardware was a bit of a chore. After that, a lot of the hack was [Dave] just remembering how we used to do things back in the day, with the eventual solution being transferring over the files to an FTP server on a Raspberry Pi.

The video below tells the whole saga, but the real treat might just be the Vintage Apparatus collection of gear. Incidentally, we really like [Dave]’s idea for storing associated bits and bobs.
