Progress Summary Relay Computer

Progress Summary Relay Computer Progress summary this page shows the current state of construction for each unit of the computer bay w bay x bay y bay z others deprecated cards complete. Architectural and circuit design tricks keep the relay count for the cpu low. the relay trainer uses edge triggered d flip flops implemented with just 1.5 dpdt relays bit.

Progress Summary Relay Computer There’s a lot to take in on this project, so be sure to go look at the ongoing logs of the underlying 16 bit relay cpu project where [peter] has been showing his progress in creating this. This relay computer project is based on the designs of dr. harry porter, who designed and built a multi wall sized fully functional relay computer at portland state university. After thinking about building a relay computer for a while, i started focusing on the flip flop design and came up with idea for a master slave flip flop with a capacitor based latch for the master side and a hold resistor based latch for the slave side. It is a dutch acronym for a project that started in june 2014 and aims to make a working and transportable relay computer. mercia is special, because it is entirely build out of relays and passive components (diodes, dipswitches, resistors and capacitors).

The spst relays used in the and and or gates close a single contact when the relay is energised. the spdt relays used in the xor gate (link), both make and break electrical contacts each time it is energised or de energised. I amuse myself by constructing a computer almost entirely out of relays. relays were used to construct computers well before vacuum tubes, transistors or integrated circuits were feasible for the task. During the weekends at school, the relay computer was designed with a limit of 268 relays (which eventually increased to 281 relays), a 8 bit data bus, a 16 bit address width, and a floating zero. Moreover, paul law has compiled an impressive website documenting the project in detail (including an online emulator of his relay computer), and there’s also a channel with lots of videos covering the progress.
