 1 | # Tokamac LC/Sonnet Presto 040
 2 |   
 3 | This is a recreation of the Tokamac LC accelerator. Sonnet sold the same board as the Presto 040.
 4 | Supported Macs are the LC, LCII and Color Classic and their Performa variants.
 5 | The schematics have been reverse engineered and a new PCB was created based on the schematics.

13 | # Notes
14 |   
15 | The only programmable part on this accelerator is a XC1736 PROM at U15 that holds the configuration for the XC3030 FPGA.
16 | Reset polarity should be set to high when programming the ROM.
