Ademir Carchano from MSX Projetos Brazil is widely known for his hardware development such the ACVS MSX2 upgrade kit, MegaRAM, ADVRAM and others. Currently he is developing a new MSX "motherboard" which goes by the title of 'MSX-UNI'. MSX-UNI can be installed on older Brazilian MSX computers (HotBit/Expert) or in a PC desktop.
The MSX-UNI board aims to be an universal board that can be attached to a host-machine like the HotBit, Expert, and so on. The MSX-UNI is a very tiny board, but has all peripherals such as IDE, drive interface, MegaRAM, Memory Mapper, FM and a free space for an SCC chip. All this on a single board. The kit includes a new power supply which can support a floppy drive, hard disk and video out.
The main components of the MSX-UNI board are:
- MSX2+ with Turbo (up to 21MHz)
- Mapper with 4MB
- Megaram with 2MB
- Free space for SCC
- Floppy interface
- All the other circuits that are necessary for a complete MSX.
The MSX-UNI is not to be mistaken for the CIEL3++. MSX-UNI is a 100% MSX implementation, with all auxiliary circuits printed on FPGA programmable logic and some basic components, such Z80, VDP, FM, clock and memory installed aside.
The MSX-UNI is expected to be released in May 2007 and will cost around €170,- ($200,-).
