Designing a single board computer that supports Bubble Memory, as well as an RC2014 Bubble Memory board.
In this post, I build a PS/2 Keyboard to TTLSerial Adapter Motivation The original reason for this project is that I wanted to build a standalone RC2014 with keyboard and display. There is an official RC2014 serial keyboard, but I find it a little inconvenient for my big fingers and poor eyesight. I have plenty …
In this video, I design and build a Z180 CPU Board for the RC2014 Motivation I wanted to try a CPU that runs at faster clock speeds and has more built-in peripherals than the Z80. More built in peripherals means less external boards needed for mundane features, and more room in the backplane for “interesting …
I set out to build a fancier CPU board: Design I wanted the CPU board to have the following features: on-board oscillator, so that a separate clock board is not necessary power-on reset circuit reset header for external reset switch status LEDs for common signals such as RD, WR, MREQ, IOREQ, M1, and HALT Below …
I this video, I install a Unix variant called Fuzix on the RC2014: No new hardware is introduced in this video, I use the same Flash-ROM/RAM board that I used for RomWBW. Thanks to William Sowerbutts for pointing me to the distribution and helping me along with a few issues. There were a couple of …
In this video, I build a new Flash ROM / RAM board and use it to install the RomWBW CP/M distribution on the RC2014: I’ve already done one video on CP/M on the RC2014, but when I built the Zeta 2 Single Board Computer, I liked Sergey Kiselev’s design so much that I thought I’d …
In this video, I try out a pair of Qume 8″ floppy disk drives with the RC2014: Most people who have read my retrocomputing series probably have some familiarity with 3 1/2″ drives or with 5 1/4″ drives. The 8″ drive preceded the 5 1/4″. I never had the experience, having entered the computer scene …
