The VTech Socratic Method

The VTech Socrates, a hybrid video game console and computer released in 1988, is the focus of a recent exploration. Initially, these devices were produced in large quantities, leading to their low prices on platforms like eBay. The author describes the condition of their Socrates upon arrival, noting it was dirty and damaged but made of durable plastic. The disassembly revealed a simple motherboard with components primarily sourced from Toshiba, including a Zilog CPU and various DRAMs. The author also discusses an AV modification to improve video output, which involved adding a video amplifier and redesigning the PCB. Despite challenges during assembly, the mod was completed, and the system was tested with a TV, yielding decent video quality but loud audio. The keyboard, which operates via infrared and requires batteries, posed its own challenges, particularly regarding its power management. The author speculates on the keyboard's design and functionality, noting the absence of a clear power switch. Overall, the exploration highlights the Socrates' unique design and the author's hands-on approach to restoring and modifying the device.

- The VTech Socrates is a hybrid console/computer from 1988, known for its low market price due to overproduction.

- The device features a simple motherboard with components mainly from Toshiba, including a Zilog CPU.

- An AV mod was created to enhance video output, despite challenges in assembly and design.

- The keyboard operates on infrared and requires batteries, with unclear power management features.

- The exploration emphasizes the author's hands-on restoration and modification efforts.

I had one of these as a kid; the slow way it drew the graphics onto the screen [1] for a new activity was an aesthetic in itself, like a coloring book being drawn and colored in before your eyes, a perfect loading screen for kids.

Wikipedia notes: The system will "draw" images by filling in areas of the screen with color one line at a time; it is not known whether this is an effect employed for the student's enjoyment or if it is due to the slow processing time of the system.

I had a look at some VTech computers at the local Toysrus (or something like that) recently, and amazingly they don't look much more advanced now than what they offered in the mid 1990s. That's pretty hard to pull off, but I think today it's a deliberate choice.

This thing was slow as balls, but as a kid I didn't really know any better... I could be wrong, but I really feel like edutainment really fell away once everyone could get a real computer with an internet connection.

Holy shit, blast from the past! My dad had got one of this and when I was born my family had already moved back to India. I booted this up when I was about 10 years old and I was so mesmerized. It was impossible to afford any game consoles for my family so this took a lot of my time. I was so impressed with how everything fit together, the robot was cute… I loved it.

My dad also had got a Tatung Einstein which never worked. Last time I went back to India (I moved to the US for higher ed) I opened it up and was excited to see that they are a bunch of chips that they taught me in Comp 101 (they were basic TTL flip flops). I brought it back with me.

I still have it, and one day I hope to have enough time and space to open it up and translate it into an FPGA as a way to brush up on my basic digital signal knowledge.

Why is the copper routing so funky? Were the PCBs drawn by hand?
