Yes, after I posted my reply last night, I noticed the appendix in the
5245 manual that mentioned the 1248 BCD options...

AFAIK the counters are plug-compatible apart from the code used on the
BCD output lines (and internally on the counter PCB, of course). So you
may not need to worry about which version you actually have. The
schematics are also very similar...
