Seems like the csync emitted by the EMV computer is either too noisey or not amplified enough for the upscaler board to get a lock on the signal.

To rectify this I have ordered:

- LM1881 eg. http://www.mmmonkey.co.uk/composite-sync-stripper-lm1881/

- EL4853 eg. http://shmups.system11.org/viewtopic.php?f=6&t=43992

- JROK Sync Cleaner

Also here is a test fit of the LCD I am using on the CRT mounting bracket.
