Data sheets?: Nat Semi's B9224 micro and UL82??? drivers

I'm working on a mid-90's car alarm built around NS' B9224AB and what seems to be (numbers have been scrubbed off these IC's) UL82003 (some digits may not be correct) by NS and Motorola.

Both are DIPs: 9224 is 40 pin; 8**** is 16 pin.

The UL8**** IC's seem to be drivers that interface the 9224's outputs and drive relays.

I'm trying to find data on these IC's at NS web site, but I think they're too old to be found there.

Any ideas where I can find data on these?

I presume that the micro is coded internally, and if it is hosed, the entire PCB has to go (no component-level repair available from Clifford alarms...)

Thanks, Dave

Loading thread data ...

9224 seems more like a date code. It's probably a mask programmed uP. The other is most like a ULN2003.
