ZXpand Interface for ZX81 and Timex-Sinclair

June 19th, 2011 1 comment

The ZXpand interface is a brand new interface for the Sinclair ZX81, and Timex-Sinclair TS/1000 Home Computers.

The ZXpand interface offers 32K of expanded memory (which is configurable to support various hi-resolution graphics modes), instant file access to .p files stored on SD memory cards and more.

The Sinclair ZX81 ZXpand interface will also allow you to connect an Atari style 9 pin joystick port to play either specially written or specially adapted games.

The ZXpand provides the following facilities:

  • SD Memory Card reader – for instant loading from / saving to .p files (used by ZX81 emulators)
  • 32K of configurable RAM memory, which can then be set up to use the various hi-resolution graphics schemes for the Sinclair ZX81.
  • New keywords are added to the system ROM to allow you to load and save programs, produce a catalogue of files on the memory
    card, configure the ZXpand Interface, and delete files.
  • You can still load programs from cassette as well as using the interface, to allow you to copy files onto the SD memory card.
  • Sub-directories are supported on the memory card.
  • The new ROM can be switched off once a program is loaded, in order to allow access to LPRINT, LLIST and COPY commands.
  • There is a built in reset button to reset the ZX81 without having to pull the power lead.

Released eSXDos v0.7.3 Beta public firmware for Divide interface

February 21st, 2010 No comments

eSXDos Divide Beta firmwareGeneral Info:

  • Firmware written primarily for the DivIDE interface, maybe for others in future.
  • Inspired by our (Phoenix & LaesQ) old ‘backbone’ project + inspiration from +D
  • Works with HDD/CD-ROM/ZIP/LS120 (LS120 can access 720KB and 1.44MB floppies)
  • Uses drivers to access filesystems (either in RAM or ROM)
  • Provides new BASIC commands
  • Will provide RST 8 hooks for user-land apps
  • Supports IM2 loading/saving (K3L’s FA part)
  • Drivers give access to the filesystem, and provide specific emulation hooks in certain cases (TRDOS, .TAP, etc)
  • There’s a device/filesystem abstraction layer, which means that BASIC or user-land programs don’t need to know anything about the underlying filesystem/device (ie, you use the same BASIC commands for all filesystems, FAT/ISO/TRD/etc)
  • Will allow up to 4 virtual drives for disk images (.trd/etc)
  • Filesystems are mapped acording to type: hd*, fd*, cd*, vd*, td*
  • FAT12/16/32 driver built-in ROM, other drivers loaded from boot filesystem on demand. (on this preview version, there was still room so TRDOS filesystem is in ROM too)
    Does not need a system file to work, common BASIC commands and FAT driver on ROM, system file loaded from boot filesystem will have additional commands, etc.
  • … more stuff which I prolly forgot
