Brian's TI Voyage™ 200 Hardware Page

The idea for this page is a blatant rip-off of this page: The Hardware of a TI-89, and since I haven't actually stolen any of the information from that page you will still need to go there for most of the interesting detail about TI-89, TI-92+ and Voyage 200 hardware. The link doesn't seem to work these days though.

However I have photos of the inside of my Voyage 200...

Notes (mine, not guaranteed to be 100% correct):

• U1 & U2 are Toshiba T6B08 - row drivers for a dot matrix LCD
• U3, U4 & U5 are Toshiba T6B07 - column drivers for a dot matrix LCD
• U6 & U7 are 128K*8 (128K byte) CMOS RAM chips (static RAM)
• U8 is a Sharp LH28F320BFHE-PBTLZ2 - a 4M byte Flash memory
• U9 is a Motorola MC68SEC000PB16 processor. (A low power CMOS version of the 68000)
• U10 is probably a custom chip of some kind
• U11 is marked HC14A - presumably six inverting buffers
• U15 is LP324M - four low power operational amplifiers
• U16 is 74HCT244 - eight tri-state buffers
• U17 is 74HC00 - four nand gates
• J3 is the Graphlink socket
• X1 is a 32.768kHz crystal for the real time clock
• BATT1 - these gold contacts are where the 6V from the AAA cells connects to the board
