[Motorola] Maxtrac 5 pin logic board question, HLN9123 basic limited masked board

[Shawn Hastwell]

Anyone know where I can pick up discriminator audio on these boards?  I got a bunch of 800MHz chassis leftover after I pulled the 16 pin boards and used them to upgrade other rigs to full signalling capable.  I threw the old 5 pin boards back in the 800 chassis and wiped them and re-init'd them as 800 conventional 2-ch units.  I want to put them to some use rather than watch them go on ebay for 5 bucks each.  If I can get the baseband audio out of them i'll use them as data channel radios for Treport, Trunker, and E-Trunker usage.

I don't have a service manual so any help would be appreciated.  Esp. if someone has an extra manual they want to part with for a reasonable price.
