Chameleon 8-16 FPGA Board
The Chameleon 8-16 Board is an Efinix T20 FPGA Board for the S-100 Bus that will hardware emulate (with an appropriate FPGA HDL Project) various classic and new design S-100 Boards.
Its features include:
- Bidirectional 0.5ns delay level shifters for full S-100 Bus signal access.
- Bus Master and Slave definitions are possible.
- Efinix T20F256 FPGA
- 16MB HyperRAM
- 2x SD Card Sockets supporting 1-bit and 4-bit modes
- HDMI Output (Display Port Mode)
- LVDS Expansion Bus I/O
- 2 x RS232 or TTL Level COM Ports with a USB Option
- IEEE-1284 Header
- 1-Wire Audio Output Capability
- Arduino UNO Socket with ADC and Local bus Expansion
- A 50Mhz Front-Panel Header (for smart SPI Based Displays)
- A IMSAI 8080 Compatible Front Panel DIP-16 Socket
- 2x Seven Segment Displays for POST and Debug Use
RetroTalker
RetroTalker is a re-creation of the classic Netronics Electric Mouth.
It has all the same features as the original while introducing needed improvements.
Existing Features:
- Uses the National Semiconductor Digitalker Chipset for human-sound speech words/phases.
- Supports up to 8 2764 EPROMs or Digitalker original SSR speech ROMs.
- On-board Audio Amplifier and speaker with an external speaker option.
- Supports TRS-80 Expansion Bus input option (just like the original!)
- Supports COSMAC-ELF Parallel Port option (just like the original!)
New Features:
- Cycle decoupled from the S-100 Bus
(The original Digitalker IC’s bus cycle was extremely slow at 880-ns.
The RetroTalker decouples the Digitalker access from the S-100 Bus to
keep from blocking other bus transactions). - STM32 NUCLEO Board for additional features:
- Emulation of Speech ROMs
- Playback of WAV Files
- On board 8MB NOR Flash
