A1000 Rejuvenator troubleshooting

[cloverskull]

Hey friends, I purchased a Rejuvenator clone board a long time ago and spent the evening trying to get it to work. My bone-stock A1000 worked as expected before installation of this board.

I installed the RAM chips, checked the orientation, checked for bent legs. All good. Checked the connection between the motherboard and the rejuvenator. All pins are where they belong. Checked orientation of custom chips. I hardwired the connections from the three lugs on the rejuvenator to the motherboard locations (28mhz, RMBCLKS, +12v) but when I power on the computer, the power LED doesn't light up and there is no video output. Paula and my 68k CPU chip get hot but nothing else seems to happen. The floppy drive is plugged in and should have power but when I insert a disk, nothing happens. Everything worked fine before installing the rejuvenator.

There's nothing in U27. Do other folks have anything here?

Perhaps I need different RAM chips? Can someone please recommend some for me? I appreciate it. I'm a bit at a loss. I'm in California, USA, and would like to sort this out quickly if I can.

Thanks!

I was able to troubleshoot and get the computer to boot with the Rejuvenator but was having some mouse related problems. Specifically, there was no vertical movement. I tried swapping and replacing the CIA chips, removing and re-seating the Rejuvenator, removing and re-seating Denise (per advice from David, the guy who makes the Parceiro).

I decided to do a once over of the board again and noticed a handful of solder bridges. So, I am not super happy about this, naturally. I cleaned up the solder bridges and now my mouse works, but I didn't expect a unit to arrive in this type of condition.

Now I am having a memory problem of some sort. I'm going to take everything apart again, pull out the multimeter, and start troubleshooting. This is pretty frustrating. I've sent @Dragonheart a message about the solder bridges and there has been no response, in spite of me being told that these units were all bench tested prior to shipping. Let's just say I'm skeptical.

Will try to resolve this next week Tuesday. Currently out of the county for 6 more days.
