bomtsjak 909 eprom replacement help

[audiofeen]

hi guys

i have to replace the eprom form my 909 as it is not syncing with my sequencer.
i have a replacement eprom from Switzerland thanks to diprec but i am not sure witch eprom on the switch board
to replace (i assume that it is on that board as all the other eproms that size are on the voicing board and as you will know look to be for the hh, cr, rd samples)
i have narrowed it down to 2 different eproms ic608 and ic609 from the schematic that i have found i think it to be
ic609 but i require someone with 909 repair experience to confirm this.
my friend rocksteadybeat recommended to ask for the dutch 909 expert bomtsjak for help.

this is the links for the schematics that i have found for the 909 the switch board unfortunately it is in 2 parts(still has the information though)
