ZX80 US vs UK..

Post by bola_dor »

What would be the differences between the ZX80 US vs UK versions? Do both have ISS 1 and 2?

Having owned both US and UK types the only difference I could detect was the television standard between the two countries ie the modulator.
Mine was a later ABS cased model suggesting issue 2 as per my UK one.

Great info.. would running 60Hz instead of 50Hz prevent some software to run? Or are there any other known implications?
Thanks

Thanks..
I am about to receive one ZX80 US soon so I am quite anxious :D
I've already made my own video back porch composite mod from http://zx.zigg.net/misc-projects/ while waiting..
(Should this be moved to the hardware forum?)
Are there any known software incompatibility?
