|Yes, we are getting a
brand new TI super computer that is compatible with
the TI 99/4a software and beyond.
This project has been kept secret until today.. The
TI User Group UK shows you the spec... however we are
looking to add an Gigabit Ethernet Controller to the
machine so that it can connect to the internet. With
this we can add products like the wnce2001 Ethernet
wireless adaptor which is a universal self
connecting device. If you have any technical
knowledge regarding low level ethernet
implementation then let us know..
way here we go with the spec.
1 ) PEB interface. The board
can run in the PEB or stand alone with a disk drive
power connector ( allows use in PC case etc ).
2 ) 2 * SD card slots. No VHDL has been created for
this yet but the connections are there anyway.
Opencores.org may have VHDL we can use.
3 ) 1 * USB connector. No VHDL exists for this but
the MSX people have a connection like this so I
thought why the hell not !
4 ) IDE interface. Again no VHDL but I'm sure we can
ask a certain Mr Nouspikel if we can copy his
design. ( Allows 2 drives )
5 ) 64 MB DDR SDRAM for the CPU - this should be
6 ) 512KB VRAM. Looks like the 9958 will be used -
not the 9938 as there is no mouse interface on the
MSX 9938 :-(
7 ) 1 * audio output from the sound generator. Don't
know about speech just yet - can use existing PEB
mounted speech if the worst comes to the worst.
8 ) 18 bit RGB output with Hsync and Vsync. Should
work on normal VGA monitor. May get SVideo also at
some point - depends of FPGA pin count.
9 ) Joystick interface.
10 ) PS2 Keyboard interface.
11 ) PS2 mouse interface. No VHDL for this but
doesn't seem too difficult.
12 ) Centronics PIO interface like RS232 card.
13 ) 9 pin RS232 channel. No VHDL yet.
14 ) Regulators to get 5V, 3V3, and 1V2. 1 Switching
regulator used for efficiency.
15 ) 1 config device to program both FPGAs.
16 ) 12MHz oscillator - multiplied internally to get
higher frequency operation.
17 ) 21MHz Xtal for video.
Production of the PCB starts shortly...
Update 13 July 2010 A
Ethernet Port has now been added to the computer.
However there are still a couple of technical
problems that must be over come. However the format
will be the standard RJ45 10/100mbps. This will
allow things like network printers and the internet
to stream to the machine. You will also be able to
connect more than one G2 together with perhaps one
as a server.
If you visit the TREFF we
hope to have a large demo of the unit for you to
Here are the newly released
pictures of the board layouts.
