I'm going to order a few boards for people to buy. These won't be 100% finished. Mostly they will just need the PLD soldering and maybe some header pins, and CPU socket.

At least some people can start building them up as there's unlikely to be any hardware changes now anyway. Mostly it's going to be firmware fixes which will of course take time.

But also as the year is flying by and I don't plan on shipping to Germany next year, I want to make sure people can get some boards sooner rather than later.

Buyers of these boards must be good at soldering and already know how to program the PLD and ROM! These are considered BETA boards and buyers should expect problems while the firmware is debugged and worked on (which will take time)


EDIT:
Though I will probably remove the JTAG header as it gets a bit in the way of PLD soldering!

Will it work on my CA401177 1040STE (no CPU socket) if I replace SM CPU with a SM socket?

My 1040STE will not be complete until it's Falcon-like.
I have no nostalgia for Falcon, but there's no limit to upgrading my 1040STE!

Its possible but I don't recommend unless your good at soldering. Many have tried and caused a lot of damage. IMHO get a socketed motherboard and don't risk it.

Thanks for suggestion.

I'm still high on having successfully replaced my 144 pin SM glue chip (the blitter was bad).
But as I recall the socket is a different beast, with pins tucked under, not out.
I'll have to look at it closely again and decide how crazy the idea is.

Mostly assembled as shown in the images. These are for people who can finish the build themselves (I don't have time to build and test fully myself)

You will need,

PGA socket
https://www.exxosforum.co.uk/atari/store2/#0181

030 CPU
https://www.exxosforum.co.uk/atari/store2/#0187

DUMMY CPU
https://www.exxosforum.co.uk/atari/store2/#0243

PLD included. You need to program your own ROM and already know how to program the firmware.


EDIT:

I've just noticed the upgraded 3.3V regulator has been missed off :roll: I will try and solder them myself as they are tiny. It will of course delay shipping as my time is limited.

EDIT2:
Sorry bumped wrong topic!
Still not had chance to look into the regulator issue yet!

Still interested in the STE536.

I don't see it in the exxos store.
Would prefer less soldering, but will solder as necessary.
(Will have a socketed 1040STE soon)

I think Exxos took it off as he is waiting for feedback from the beta testers
