Do we have correct schematics for this 1541 board? It uses 74LS123 in place of DM9602 but all the schematics I found refer to the 9602 mulitvibrator, which - as Ruud noticed here: http://www.baltissen.org/newhtm/1541a.htm seems not to be a drop-in replacement. Also I found that: http://www.zimmers.net/anonftp/pub/cbm/schematics/drives/new/1541/boards.txt says: "1541A2 250446-01 A 74LS123 replaces the 9602 at UD4" but all 250442 I have are already equipped with '123 -- SD!
