This seems so simple even I, soldering challenged that I am, could install it!
What could I expect the display to look like on a T/S1000 with LCD and Pokemon's ZX8-CCB installed?

If you are looking for a real speed-up solution, go for the modification called "noWAIT".
The program that I used for benchmarking the ZX81, TS1000, TS1500 and ZX81 emulator grew out of a conversation on the board about speeding up Sinclair Basic:
5 LET A=40
10 LET S=PEEK 16436+256*PEEK 16437
20 FOR K=1 TO 1000
40 NEXT K
50 LET E=PEEK 16436+256*PEEK 16437
60 PRINT S,E,S-E
The test was to see how the speed changed based on using different values for "Goto" and is in frames (60 frames per second in US).
A few things of note from these tests:
The ZX81 is MUCH faster than the TS1000, even allowing for the 50hz versus 60hz of the US model.
The TS1500 is consistantly a few frames slower than the TS1000
There is no "real" way to test FAST mode since the FRAMES variable (locations 16436 & 16437) are not updated
Look at the results of the compiled version!

** Mcoder doesn't allow the use of strings so these tests could not be performed.
*** I "hacked" a TS1000 by cutting the R30 resistor to make it run at 50HZ instead of 60HZ. Though the screen rolls on my US TV, the speed pick up is about 60% over the standard 60HZ machine!
