Computing engineer. Collaborating lecturer at University of Seville.
divtiesus. DivTIESUS is a SD/MMC interface for the ZX Spectrum, compatible with ESXDOS. It is not a clone of Mario Pratto's DivMMC.
51zx81putil. An utility to manage .P files for the ZX81.
18simple_sdram_controller. A very simple SDRAM controller for FPGA written in Verilog. It exposes a SRAM-like interface to the rest of the FPGA fabric
14fpga_tv. Some crazy experiments about using a FPGA to transmit a TV signal old-style
13zxuno_spectrum_core. A ZX Spectrum hardware description for the ZXUNO hardware and other platforms
12turboloader. Parametrized turbo loader for ZX Spectrum (and possibly, other Z80-based computers)
12divtiesus_utils. Source code for some utilities I've written to support the DivTIESUS interface
6pano_logic. Various cores and experiments for Pano Logic Zero Client G1 and G2
5modplay. A basic, yet comprehensive mod (as in AMIGA Protracker) player
5spi_master. A SPI master interface core for CPLD/FPGA
5vga_text_driver. A simple 80x25 VGA text controller, modelled to behave as a RAM for the rest of the logic.
3jupiter_ace_tap_to_tzx. Quick and dirty translator from Jupiter ACE TAP files (not exactly the same as Spectrum TAP files) into TZX format
3mmu_z80. A simple MMu chip for Z80 and possibly, other CPUs.
2playmid. A tiny MIDI player for the ZX Spectrum 128K. It uses the MIDI OUT connector available in those models. Also works in the ZX-UNO with the MIDI plugin (or compatible).
2i8088_tester. A small core and board to test Intel 8088 chips for minimal functionality
2fpga_training_modules. A collection of Verilog modules that adds a number of useful indicators on screen, similar to leds, switches and displays that most trainers have
1timex_hicolour_slideshow_creator. A small C utility that takes a series of SCR files containing two 6144 blocks that comprises a Timex HiColour screen and generates a PZX file with a slideshow of all of them
13e. A command-line utility to manage IDEDOS devices (as used by the +3e project)
1wload. ESXDOS dot command to upload binary files over the air from PC to wifi equiped ZXUNO
