Original E39 Head Unit Modernized

October 28, 2025 by 24 Comments

Although most modern cars have moved to using proprietary components nearly everywhere, especially when it comes to infotainment systems, for a brief moment which peaked in the 90s and 00s most cars shipped with radios that fit in a standard size opening called a DIN slot. If you wanted a new Pioneer or Kenwood stereo it was usually a simple matter to slide the factory radio out and put your choice of aftermarket head unit in its place. [Stefan] has an E39 BMW from this era and wanted to upgrade the factory radio but use the original hardware instead of replacing it.

This isn’t just a simple stereo upgrade either. [Stefan] has gone all-out for this build which he started in 2020. Beginning with a Kotlin/Jetpack Compose Linux application to handle control input from the vehicle’s various knobs and buttons he moved on to a map application and an on-screen keyboard. From there he implemented VGA to send video to the OEM screen, and now has a fully functional system based on a Raspberry Pi. It does everything the original unit can do including playing music and showing the feed from the backup camera, plus adds plenty of new, modern features like Bluetooth.

For a certain classic car enthusiast, this build hits a sweet spot of modernizing a true classic like the E39 without removing or permanently modifying any OEM components. The amount of work that went into it is pretty staggering as well, with [Stephan] putting in over 100 hours of work just to get the video signal timing correct. We also like it because it reminds us of the flash-in-the-pan “carputer” trend from the late 00s where people in the pre-smartphone age were shoving all kinds of computing horsepower in their trunks.

A Non-Sony Playstation Motherboard Replacement

July 27, 2025 by 12 Comments

As hardware ages, it becomes harder and harder to keep it in service. Whether that’s because of physical aging or lack of support from the company who built it in the first place, time is not generally good for electronics, especially when it comes to our beloved retro gaming systems. The first Playstation, for example, is starting to see some of the deleterious effects of having originally been built in the 90s, and [LorentioB] has a new, third-party motherboard to bring to the table to keep these systems online as well as adding some features in that Sony removed.

The motherboard is known as the nsOne, meaning Not Sony’s One since this is the first motherboard built by a single person outside of Sony. It’s not based on any FPGAs or emulators and is completely compatible with all of the original hardware, chips, and other circuitry of the original Playstation. Based on the PU-23 series, it even revives the removed parallel port, which Sony removed after the first versions of the hardware because of region locking concerns and other pro-consumer issues. Every chip footprint and connector was reverse engineered manually, using optical sanding, scanning, and net-by-net tracing.

For such a complex piece of hardware this is quite the feat, and for anyone who wants to restore old hardware or add the parallel port back on to their system this could be a game changer. [LorentioB] is not quite finished yet but hopes to have a finished version shortly. As far as fully opening up the system goes, there are some software hacks to look at that allow more games to run on the system and some hardware hacks that open the system up as well.

Retrocomputing, Time To Hang Up The Original Hardware?

June 28, 2022 by 57 Comments

For those of us with penchant for older technology, there’s something special about operating with older hardware. Whether it’s a decades-old camera, a vintage keyboard, or a home computer from the 1980s, the modern equivalent just doesn’t quite compare. But working with older parts definitely isn’t for the faint-hearted, as the passage of time has taken its toll on their reliability. Is it time to recognize that the supply of replacement vintage parts is not infinite, and to switch from using original hardware to more modern alternatives? [Retro Recipes] poses this question after a particularly difficult-to-find Amiga fault, and discusses it while evaluating a replacement Amiga made entirely from modern parts.

The new Amiga in question is a recreation of an A1200 with a re-manufactured case and keyboard, and the guts of an A500 Mini retro console taking the place of the Commodore board. He goes through the process of making an Amiga hard drive image on a USB drive using the image from his original drive in his teenage years, and boots it both on the 500 Mini based machine and on the UAE emulator on a Mac laptop. You can follow him in the video below the break.

We can see the logic in treating original hardware as a precious resource that’s not to be run up for fear of breaking it, but by the same token we’re still standing by that first sentence. But should the enjoyment of an older machine be limited only to those who have an original? We think not, so if enjoying an Amiga without an Amiga can be as good as the real thing then we’re all for it.

Of course, for those whose original Amigas have already broken, there are other ways to bring them back.
