SLA7073 Stepper controller

[xtal]

I have taken the SLA7062 schematic on PMINMO and modified it for
SLA7073 [ which is !ustep version of SLA7078] and even made a pcb
using express pcb..... it's only been tested with motors and no load....

I'll see if I can dig up the schematic and pcb layout..I've got it somewhere.

The schematic is in eagle ,, note the 6 pin connector not shown

The pcb final is sla70739z.pcb ... note the 6 pin connector ..
you may have to rearrange your motor plug ......

The single sided pcb is expresspcb and layed out for toner transfer
and yes there are jumpers [ 8 if I counted right]
I used pnp transistors instead of pfets and never got around to
adjusting rc properties for the idle current delay....

enjoy....

ps I was able to get samples from allegro
