Home ∕ Electronics Projects ∕ Z80 Retrocomputing 5 – Single Stepper for RC2014
I'm very interested with the Dr. Scott's project TIL311 Bus Monitor Board and this Step Executor Board.
This time I'd like to make this board with my favorite parts like pod with tab control, alternate Toggle switch for single stepper.
Therefore I decided to make my own...
**This is a hobby project and comes with no official support. The PCB schematic and board design files are offered 'as is' with no claims made about their fitness for any specific purpose.**
The Multicomper motherboard is a simple platform for creating a 'Multicomp' computer based on the design work of Grant Searle - which can be found here:
V2 of my ZTO-80 SBC project, with the end goal of having color graphics(?) along with a BASIC interpreter based off of NASCOM BASIC. A future revision may include support for CP/M.
Feel free to clone this project. Just be sure to acknowledge me as printed below:

SC118 v1.1 (www.scc.me.uk)
Z80 processor card for Z50Bus
This card can work in a modest way as a Single Board Computer (SBC) or be used part of a larger system on a Z50Bus backplane.

"The Missing Module"
Pairing this module with S. Cousins SC108 (CPU+memory) or SC114 SBC form a complete CP/M computer system.
The beauty with #61 is that it can be used as a
1) bus clock
2) serial interface
4) or a combination of these functions.
In addition, it allows the CPU to run asynchronously up to 24Mhz (Z80) or 33Mhz (Z180)
Banked EPROM RAM Board
- EPROM can be enabled/disabled with write to register
- EPROM occupies first 16K of address space
- First or Second bank of 16K in EPROM can be selected
- Modified to use ZIFF Socket
