Does anyone have pinouts or spare cables for this controller. It's like the UDC, but much longer. I read the firmware off of the eprom and it does have support for 3.5" disk drives, but so far I can only get it to work with 2 Disk II drives in a II+. For some reason it won't work in a Platinum IIe, and I think I had it working in a beige IIe, but they have been put away for now, so I can't try it again to be sure. Anyway, I could use the cables or the pinout so I can make some. 


Mines in storage so it'll be a few days before I can get at it.
I used mine in a platinum IIe so maybe the firmware needs an
update.
There's two EPROMs I have on my site that'll work in this card,
the vtech_udc and the laser_udc.
If you want to compare cards, there's a pic of the component side of
mine there too, without adapters so I could scan it easier.
My "full length" VTech/Laser card came with firmware that properly supported the original Unidisk 3.5 (aka Liron) but which had problems with Appledisk 3.5 drives. A later 1/2 size card from Laser came with different firmware, showing the opposite behavior! I burned a copy of the older one and it worked fine on the new card - for those rare times when you just gotta have a Unidisk working with a IIe.
