/********************************************
Laser Base / Future Flash driver
IC marked as Z1 is probably protection device
mapped in memory region f800-fbff
(simil. to the one used in Parallel Turn)
Reads form this device depends on previous
writes (adr, data), address and previous
operation (read or write).
Pinout is almost identical to 2716 - type EPROM,
except separated /RD and /WR signals and lacks
of /CS

--------- ----- ------ ---- -----------------------------
I believe the F.F. markings on these chips show that
these roms have been changed to Future Flash.
It is unknown what the Z1 chip is, but the label screened
on the board under the socket says 2716. All the identifying
numbers have been scratched off and has Z1 stamped on it.
It appears that each one was then numbered by hand in red
marker and stamped with white ink with Z1.
The Z1 chip was read from 3 different boards, it is Valid.
The chips were numbered 69, 82 & 624, all three read the same.
Turns out it was a TI2716. The TI chip has A10 on a different
pin than a standard 2716.
