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.

flashrom v0.9.6.1-r1564 on Linux 3.2.29 (i686)
flashrom is free software, get the source code at http://www.flashrom.org

flashrom was built with libpci 3.1.9, GCC 4.7.1, little endian
Command line (6 args): flashrom --programmer nicrealtek:pci=00:09.0 -V -f
-r bios
Calibrating delay loop... OS timer resolution is 1 usecs, 504M loops per
second, delay more than 10% too short (got 73% of expected delay),
recalculating... 382M loops per second, delay more than 10% too short (got
55% of expected delay), recalculating... 461M loops per second, delay more
than 10% too short (got 67% of expected delay), recalculating... 461M loops
per second, delay more than 10% too short (got 67% of delay loop is
unreliable, trying to continue expected delay), recalculating... 461M loops
per second, 10 myus = 8 us, 100 myus = 67 us, 1000 myus = 689 us, 10000
myus = 7020 us, 4 myus = 4 us, OK.

No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.
