Thanks John, I'm more on the side of being a newbie rather than a champion though :-)
I've modified the source to allow specifying the start address for the upload, this way Xyyzz yy is the MSB, zz the LSB. I'll have a look at the other monitors (especially since I'll soon start my Z80 card!), but this should suffice for my coding efforts. Attaching the source... Hopefully I'll be able to test this on a V2 card, if Todd gets enough interest in pre-orders.
