hi!
which one? is it known to work with flashrom? please also include a verbose log (i.e. add -V to the command line).

Oooops. It was MC68705P3S microcontoller, sorry. But it looks just like 27xx, trust me ;-)
Just tried to read soviet (1992) K573RF6A, which is the exact copy of 2764 (I expect this one is working and contains ZX Spectrum clone ROM), with the same result.
please also include a verbose log (i.e. add -V to the command line).
