...It is not optimized (never meant to be), the CP/M3 port working on it is very crude and the bit-banging SPI over AY's I/O ports is terribly slow when it comes to accessing the SD Card adapter (C:). There are several awkwardness in the design, e.g., the first occurence of the ~HALT signal is disconnecting ROM, leaving only the RAM to be accessible by the CPU until RESET (actually, it's this feature that made CP/M bootable on it!). Of the 128kB of available RAM, only 96kB can be used, the upper 32kB is always the same (CP/M's BDOS and BIOS are there), the lower 32kB can be banked on and off by the CP/M BIOS. It is being used for the 12kB ramdisk(A:) and for storing the copy of the CCP (CP/M's shell) so it does not need to be loaded from the SD Card. ...

...This driver allows connection to a remote disk image registered as N: and a remote character device (e.g. serial console) registered as SPCNET: (namely, one can type `DEVICE aux:=spcnet` to redirect AUX: to SPCNET: and use it as a serial port over ethernet). Proven to work on the real thing and in the FUSE emulator. This driver can work along with spectram.fid driver exposing unused part of Spectranet's RAM as the M: ramdisk. NO BINARY RELEASES! To make use of this driver, you need to edit the hardcoded IP address of the remote host you wish to connect, compile the driver code with Pasmo assembler, run FIDCSUM on it and copy the final binary to your bootable disk. Caveats: - Only 16MB disk images are supported. - All errors are non-recoverable and require hardware reset.

CP/M Plus on ZX Spectrum +3 has ability to load device drivers from normal disk files (with .fid extension) on boot. A Spectranet device (apart from being networking interface) contains 128kB of extra RAM that can be accessed even with the Spectranet firmware disabled. This project proposes a FID driver that exposes Spectranet's extra memory as a ramdisk to the CP/M Plus system. Changes in v1.1: keep floppy drive motor state (as set by CP/M) when paging in Spectranet RAM (to avoid motor jumps). Unfortunately, motor state is controlled by the same hardware register as +3's memory paging features! ...

CuteMouse is a DOS based mouse driver, fully written in assembly language. It's optimized for size (and speed) to allocate as small as possible amount of your precious 640KB RAM. It currently supports serial and PS/2 mice and, if BIOS support present an

scmRTOS is tiny Real-Time Preemptive Operating System intended for use with Single-Chip Microcontrollers. scmRTOS is capable to run on small uCs with as little amount of RAM as 512 bytes. The RTOS is written on C++ and supports various platforms.

This project was moved to https://gitlab.c3sl.ufpr.br/roberto/cmips The code here is no longer up to date. The VHDL model mimics the pipeline design described in Patterson & Hennessy's book (Computer Organisation and Design) and is an almost complete implementation of the MIPS32r2 instruction set. The TLB and assorted control registers will be included soon (as of fev 2015). The model was synthesized for an Altera EP4CE30F23. The model uses up 15% of combinational blocks and 5%...

EM-65C02 emulates a Western Design Centre (WDC) 65C02 microprocessor on a Microchip PIC24/33 microcontroller. The code supports varying amounts of RAM and ROM depending on the features of the host device. The emulation speed depends on the device and its oscillator configuration. A PIC24EP running at 70MIPS has emulates a 65C02 running at about 6Mhz. The example code configuration uses a copy of the BBC BASIC ROM image and a simulation of enough of the Acorn MOS to make the BASIC work using a serial UART connection.

...Meant for beginner or advanced programmers on C or ASM, Nanux can help you understand the functions of the operating system, or create one by yourself. Minimal requirements: - x86 Arquitecture, PC - CPU Intel Pentium I, 200 MHz or newer, (maybe AMD, but is not recommended) - 4 MiB of RAM - CD/DVD ROM, USB or Floppy to run the ISO Image - keyboard /*Future updates are coming :) */ ==================================== For any questions or comments about the project you can write me at: - bojidar_bob@abv.bg - bozhidar1991@gmail.com - Facebook: Bozhidar Peychev Please rate and comment this nice OS :) Thanks for using Nanux Kernel ====================================
