Out of curiosity I hooked up my little 5" CRT TV to the Elf to see if it was any different, and it is:

So no rolling/flickering, but I think perhaps that there is some software setup needed. Need to do some more reading.
Annoyingly the DIP for the thru hole version is still not here
EDIT - I have gone through the build docs and found a video test which I'll try later

800XL and 65XE both with Ultimate1MB,VBXL/XE & PokeyMax, SIDE3, SDrive Max, 2x 1010 cassette, 2x 1050 one with Happy mod, 3x 2600 Jr, 7800 and Lynx II
Approx 20 STs, including a 520 STM, 520 STFMs, 3x Mega ST, MSTE & 2x 32 Mhz boosted STEs
Plus the rest, totalling around 50 machines including a QL, 3x BBC Model B, Electron, Spectrums, ZX81 etc...
OK so the video test made no difference, I really think I need to get that DIP IC to complete the through hole board done as it is easier to build and easier to troubleshoot, so lets hope it arrives today.

The most frustrating part of all projects: waiting for parts to arrive...
Especially since the IC didn't arrive...
I might order from somebody else just to cover all bases.

Ah, bummer...
I've ordered another from elswhere. Bit annoying as the original one was ordered from a trusted seller on eBay. Had a couple lately where trusted sellers have failed badly.

Never happened to me yet, touch wood...
Fingers crossed
It's annoying as I've built up quite a few decent eBay sellers, so to start losing some is not really what I want.

I do agree, it's really annoying.
Aaaand, it just arrived!!! It took 2 weeks, which is really quite a long time. I'll be interested to see how quickly the other one I ordered takes to arrive.
Also some good news:

This is essentially an image showing the contents of RAM, just a simple test program - 61, 69 entered at locations 00 and 01 and that is run, but it is a good video signal. At least I know what the SMD version should look like.
Hopefully I can get the SMD version working now I know what to expect.
