[Coco] CoCo-XT RTC ROM and disk

Ok, received my tube of 2764A chips.  I've tried twice (each with a new
chip) and when I put it in my CoCo-XT card it does not recognize the
CoCo-XT.  It just boots to the normal CoCo3 screen.  When I put the old
v2.3 ROM back it it boots fine so I didn't blow that part up.  Both chips
passed verification, so that should be fine.

I'm using a USBPrg GQ-4X programmer (mine is the 4x not the 4x4 which is
the current version -
http://www.mcumall.com/comersus/store/comersus_viewItem.asp?idProduct=4282,
only for reference to help me out not an advertisement, as naturally I'm
having trouble).  When I open the XT-ROM30.Bin, I have a choice of Read
mode, Fill Mode and File offset. I just chose defaults, Read Mode = Normal,
Fill Mode = Normal, File Offset = 000000.

Before I start the trial and error process of burn, test, UV erase, does
anyone have any guidance?

Thanks,
John.
