i found this info about the lynx II, anyone know where i can find these 2 chips as described below or the main board they are containd on

Thanks


For the technically minded, the Lynx has two basic chips that form a
cooperative set of co-processing subsystems that maximize the Lynx's
performance by sharing the work of executing a game program. These
chips are called Mikey and Suzy.

Mikey (16-bit custom CMOS chip running at 16MHz)
- MOS 65C02 processor running at up to 4MHz (~3.6MHz average)
8-bit CPU, 16-bit address space
- Sound engine
4 channel sound
8-bit DAC for each channel
(4 channels x 8-bits/channel = 32 bits commonly quoted)
Atari reports the range is "100Hz to above the range of human
hearing"; spectrum analysis shows the range may go as low as 32Hz.
Stereo with panning (mono for original Lynx)
- Video DMA driver for LCD display
4096 color (12-bit) palette
16 simultaneous colors (4 bits) from palette per scanline (more than 16
colors can be displayed by changing palettes after each scanline)
- System timers
- Interrupt controller
- UART (for ComLynx)
- 512 bytes of bootstrap and game-card loading ROM

Suzy (16-bit custom CMOS chip running at 16MHz)
- Blitter (bit-map block transfer) unit
- Graphics engine
Hardware drawing support
Unlimited number of high-speed sprites with collision detection
Hardware high-speed sprite scaling, distortion, and tilting effects
Hardware decoding of compressed sprite data
Hardware clipping and multi-directional scrolling
Variable frame rate (up to 75 frames/second)
160 x 102 "triad" standard resolution (16,320 addressable pixels)
(A triad is three LCD elements: red, green, and blue)
Capability of 480 x 102 artificially high resolution
- Math co-processor
Hardware 16-bit multiply and divide (32-bit answer)
Parallel processing of single multiply or divide instruction

The Lynx contains 64K (half a megabit) of 120ns DRAM. Game cards
currently hold 128K (1 megabit) or 256K (2 megabits) of ROM, but there
is a maximum capacity of up to 2 megabytes (16 megabits) on one game card.
In theory, this limit can be exceeded, either with bank-switching
hardware in the card, or by using a ROM power on/off line as an extra
address line (up to 4 megabytes

What are you interested in it for? The processor and related technology is probably 20+ years old. It seems to be a discription of a very old Atari (early to mid 80's? or similar) game console.
