## Stateless TCP (1995)

**URL:** https://archive.mycal.net/projects/stateless_tcp/
**Type:** Coined concept, engineering notebook transcript
**Date:** Late 1995

**Text excerpt:**
Back in late 1995 I coined the term "Stateless TCP" to describe a TCP like machine that could act as a webserver but required no state for the TCP or webserver Engine. Theoretically it could handle an unlimited number of simultaneous connections without having to maintain a connection table. The only state it had was the content that it was sending. This could be encoded in the sequence number of the TCP packet. So the Sequence number also served as an offset into the content. The TCP port number served as the connection identifier. An Ack in this scheme was really a request for more data.

**Backstory:**
Term "Stateless TCP" coined by author in late 1995 to describe TCP-like machine acting as webserver requiring no state for TCP or webserver engine. Theoretically capable of handling unlimited number of simultaneous connections without connection table maintenance. Key insight: sequence number encodes content offset; TCP port serves as connection identifier; ACK functions as data request rather than acknowledgment. This thought experiment directly influenced iReady's silicon TCP/IP design philosophy and the hardware state machine implementations that followed.

**Coined terms:** stateless-tcp-server, port-as-identifier, sequence-as-offset, ack-as-request

## TCP/IP in Silicon — First Hardware TCP/IP State Machine (1996)

**URL:** https://archive.mycal.net/projects/silicon_tcp/
**Type:** Hardware innovation, iReady Corporation
**Date:** 1996

**Text excerpt:**
Shown to the left is the first ever TCP/IP state-machine in hardware, circa 1996. This was the first board iReady turned out and we took turns wrapping the connections between the Xilinx FPGAs all night long to meet a demo deadline. The chip on this board is the iReady chip designed by Wai-king (waking) Yeung and we are very proud of it.

**Backstory:**
1996: iReady Corporation founding with mission to implement TCP/IP in hardware gates. First board development: team hand-wrapped connections between Xilinx FPGA chips working through night shifts to achieve demo deadline. iReady chip designed by Wai-king Yeung. Result: first hardware TCP/IP state machine — eliminated software TCP/IP stack entirely, processing network packets in silicon at wire speed. This architecture became the foundation for iReady's commercial product line, eventually leading to the TDK Internet Modem, Internet Game Boy, and Gigabit TCP Offload Engine.

**Coined terms:** silicon-tcp-architecture, iready-chip, hardware-tcp-ip-stack, limited-state-tcp-1996, stateless-tcp-1996, hardware-tcp-buffers-1996

## iReady iRouter (1996)

**URL:** https://archive.mycal.net/projects/iRouter/
**Type:** Software/hardware design proposal
**Date:** 1996

**Text excerpt:**
This was what I wanted to do when we were talking about the iReady startup before we decided to do Silicon TCP. I actually started the project and worked on it for a few weeks before the project was killed off for what the guys thought was the sexier silicon TCP/IP. An observation: Anyone who says they worked on the original iRouter "module proxy" scheme has been inspired by this project.

**Backstory:**
Written during early iReady startup phase as proposal for consumer router product. After few weeks of development, project was cancelled in favor of "sexier" silicon TCP/IP approach. Author notes the irony: consumer routers became a major market within years. iRouter proposed NAT, port mapping, virtual network architecture, and a "module proxy system" — concepts that became standard in consumer networking hardware. The iRouter spec predates commercial NAT routers.

**Coined terms:** virtual-network-architecture, ip-port-mapper, module-proxy-system, rfc-1597-private-addressing

## World's First Internet Game Boy (1999)

**URL:** https://archive.mycal.net/projects/gameboy/
**Type:** Hardware + software product, iReady Corporation
**Date:** 1999

**Text excerpt:**
In 1999 we created the first ever internet Game Boy, maybe the first ever internet enabled gaming system that wasn't a PC. It consisted of 3 pieces: a Game Boy cartridge with iReady Game Boy City, the iDongle (serial to IR adapter), and the PHS phone. The Game Boy cartridge communicated to the PHS phone via serial over IR, in-turn connecting the Game Boy to the internet. We went to Tokyo Japan for a demo and connected the Game Boy to the internet using a PHS phone and walked around Akihabara playing an internet connected game.

**Backstory:**
Created in 1999 at iReady Corporation as world's first internet-enabled Game Boy, possibly first internet-enabled gaming system that wasn't a PC. System comprised three components: custom Game Boy cartridge running "Game Boy City," iDongle serial-to-IR adapter, and PHS mobile phone for internet connectivity. Live demo conducted walking through Akihabara, Tokyo. Represents early convergence of mobile internet and gaming, predating modern smartphone gaming by nearly a decade.

**Coined terms:** idongle, gameboy-city, phs-mobile-gaming

## TDK Internet Modem / IMM — First Internet-Enabled Modem (1999)

**URL:** https://archive.mycal.net/projects/TDK_IMM_Modem/
**Type:** Hardware product, iReady Corporation + TDK + Seiko
**Date:** 1999

**Text excerpt:**
As far as I know this was the first ever Internet Enabled Modem. It used IR commands (Internet Ready) that allowed TCP and UDP sockets to be utilized via the modem's serial port. It was the first to use what I called "Streaming Sockets" — where an internet socket was mapped to a serial data stream. It made the AT command interface internet aware.

**Backstory:**
Conceived in 1999 when author convinced iReady partner Seiko Instruments and modem manufacturer TDK to build internet-enabled modem. Author designed command interface, firmware, and contributed to hardware design. Key innovation: IR (Internet Ready) command extensions to standard AT modem interface, enabling TCP/UDP sockets via serial port without host TCP/IP stack. "Streaming Sockets" concept — mapping internet socket to serial data stream — anticipated modern IoT serial-to-cloud architectures.

**Coined terms:** ir-commands, streaming-socket, serial-internet-architecture

## 8BitE — Pre-IoT Smart Home Ethernet Controller (1999)

**URL:** https://archive.mycal.net/projects/8BitE/
**Type:** Hardware prototype
**Date:** December 1999

**Text excerpt:**
I wanted a standalone Ethernet device that didn't require a computer to be on. I already had 1000 feet of Cat 5 strung all over the house and a telecom room, plus I had broadband 24x7 internet with a static IP address. I wanted to be able to control irrigation, lights, and home monitoring over the internet. My goal was to use a simple 8-bit processor talking to a standalone Ethernet controller that gave the 8-bit processor full internet access. The 8BitE used a SCR for valve switching.

**Backstory:**
Conceived in late 1990s through comp.home.automation Usenet discussions, particularly with Tim Shephard about home automation projects including irrigation control. Author rejected contemporary approach of leaving a PC running 24/7 as wasteful. Solution: 8-bit microcontroller connected to standalone Ethernet controller, enabling internet-connected home automation without a host computer. The SCR (Silicon-Controlled Rectifier) valve switching technique was novel for irrigation control applications. Predates commercial IoT smart home devices by over a decade.

**Coined terms:** standalone-ethernet-controller, scr-valve-switching, internet-infrastructure-1996
