TTL inside
Log from Hackaday TTLers
Recently Steve Toner showed his sticker "TTL inside": https://hackaday.io/project/27392-stupid-computer/log/147982-logo So I decided to order my own version of that (in RED): After applying to the plastic box, which could be used for my future TTL computer,...

How TTL beat DTL
Log from DTL binary clock
I stumbled upon a blog post by David Laws, written in 2015 for the Computer History Museum about how TTL overtook DTL. Fascinating read. TL;DR: Fairchild sticks with DTL, TI invests in TTL and becomes the leader. But the battle was not as clear cut as...

Casing + TTL-fail.
Log from Improbable AVR -> 8088 substitution for PC/XT
It's time to case-up the 8088 system so I can reclaim my coffee/dinner-table. (I found this motherboard in a "scrap PCB's" box. Amazing it survived all those years of storage, nevermind the countless diggings-through-those-boxes!).I've settled on an...

ECM-16/TTL Pilot-1 computer
Log from ECM-16/TTL homebrew computer
UPD: I created a new project dedicated exclusively for this Pilot-1 cpu.This is fully functional, albeit severely limited, automated calculating machine. It can be viewed as having a kind of Harvard architecture, as it has all instructions in ROM, and...

TTL computer ROM is feature complete
Log from Gigatron TTL microcomputer
After 360 commits my coding frenzy has reached a conclusion: ROM v1 is feature complete! The kit will ship not with one but with two fast paced games: Snake and Racer. Sound improved and the serial loader is reliable, which is great for hacking...

Gigatron! The TTL computer as a kit
Log from Gigatron TTL microcomputer
Some months ago my good friend Walter has silently joined the project. The reason is that I receive a lot of enthusiasm whenever I show this to friends, to the point where one is already seriously trying to write a chess program for it....

Building a full computer around it
Log from 1 Square Inch TTL CPU
Today, the idea of the KOBOLD computer was published here at Hackaday. You can find it here: Kobold - retro TTL computer

Contemplation of multi-word data transfers inside ECM-16/TTL computer
Log from ECM-16/TTL homebrew computer
This is an expansion over addressing logic structure described previously.I think there is a need for providing a means to transfer blocks of data between registers and between registers and memory in a single instruction. This should increase execution...

A simpler ALU (for the Kobold CPU)
Log from 4 bit TTL ALU
For my new project, the KOBOLD Retro TTL computer (that will be a full computer with minimal number of parts), I designed a simpler ALU. For 4 bits, it has only 4 IC's instead of 7. It can also shift right ! It can be found in this Kobold project...

Assembly Language Reference
Log from DM-01: 8-bit 74xx computer
The assembly language for the 74xx Computer has been finalized and documented: https://github.com/DutchMaker/TTL-computer/blob/master/Documentation/74xx-Assembly-Language.mdEverything that is mentioned in the reference is also implemented in the...

Log from Kobold K2 - RISC TTL Computer
Check my new project, the Isetta TTL computer ! It will be a single board TTL computer with video output, that can run 6502 programs and also Z80 programs at a good speed ! It is expected to run Apple ][, ZX Spectrum and Commodore 64 programs with...

Working PCB version
Log from Gigatron TTL microcomputer
The breadboard TTL color computer has a PCB baby now. Her heart beats at 6.25 MHz. Here you see the little one sleeping and dreaming of her mom. Mother and baby are doing well. Father will be fine soon also.
