Recommended Posts

I've uploaded a new release of my Highspeed SIO patch to my website

http://www.horus.com/~hias/atari/#hipatch

 

Changes since the last release (V1.20):

 

Optimized highspeed code

NMI patch no longer necessary for 126kbit/sec

126kBit work both with new XL/XE OS and old 400/800 OS

Code can be compiled as Ultra speed only version

 

so long,

Just burn it to your EEPROM and enjoy!

 

 

 

Fantastic. Any specifics on the EEPROM I'll need? Assume it's just 8k right? Something like a 28C64B?
