Can anyone identify this Driver board

[SteveS]

I am going to change my controller on a mill that I bought and need to know if anyone knows what this driver board is. The original builder took a dremel or something and ground off the identification information in middle of the board. The original manufacturer is out of business.

Driver board uses Toshiba TA8435H ICs and was probably offered in a 4 axis driver board also.

My biggest reason for trying to keep it is that the steppers are over 3 amps and driver boards at that size are pricier than I can afford right now.

Sorry I can't help with the ID but if yuo just need to get that board going you can probably download the PDF datasheet for the Toshiba chips and work out the pin connections based on that. The board looks fairly straightforward and easy enough to trace connections on.

Romanlini - I did that and traced the pins from each to the jumper output block. It would just give me a little more confidence to have a spec sheet of the board. A good thing is that I am only replacing the breakout board and most all the other wiring is carry over.

If I counted and traced right, the input to the Toshiba chips are at pins #5 and #7, which correspond to cw/cww and CK1. I have an email at this time to the BOB supplier on advise for which connector matchup to use with their board.
