Thanks for the confirmation in real life.

Rotary is good for simple binary selections but I am selecting 128K, 64K, 32K now. Its why the jumper settings are getting more complicated.

Yes I did. I just wanted to see if I could do it in Powershell as a challenge to myself.

Hopefully this will be the last design of this board!

I need to create a new ROM image and build it up...

A month later... I actually soldered one up!

Next to work on the ROM...

Sweeeeeeeeeet!

Not sure why they showing up on D:

But thanks to Atarian Computing for that bit of black magic voodoo!

I'm not having much luck with YAART though

EDIT:

OK I ballsed up one of the jumper links locations on the PCB.. I put a selection jumper on the ST side on A15 not the ROM side

Onto V9 then...

V9 done.

I've moved the "6" in "GEMBENCH 6" closer as it looked like "60" because of the jumper hole

and now looking at the image it seems to have moved to somewhere I didn't put it

Fixed the jumper link fekup.

Also changed the cap from 5mm to 2.5mm as 5mm caps in the size I want seem hard to find

But more choice in 2.5mm.. Anyway, its swapped now.

So they now in the basket awaiting for me to punch send on the current pcb orders...

V9 Built and tested fine finally!

Will start collecting parts to build up a batch of these to add to my store over the next couple of weeks or so...

Very Nice Exxos.. any idea on pricing yet?

I might have missed it if it was early in the thread.
