dunlop univibe rev b? schematic?

[pinkjimiphoton]

hi peeps,
i picked up an older basket case univibe, its a rev b which isn't even close to the rev A schem i found.
i think i roasted the 14584 chip on the switch board... so gotta swap that out...

but does anyone by any chance have a schematic for this variant they could share, please?
thanks!!!
