Pretty much this...
This can be a really cheap board, and used with my dual tos board. I can't really add ROM to this because it would have to be sold at a higher price than the dualtos boards (otherwise I would risk writing off my dualtos board stock :roll: ) But I guess I could think about doing a small batch, I mean the T-board was pushing like £40 anyway IIRC.

Looks so much easier than mine was going to be with the 3 logic chips etc, well done and thank you.

Re: exxos blog - random goings on
I did just try a quick test with a ROM.. but problem is with this intending to solder on top of the CPU, the ROM itself gets in the way of being able to solder to the CPU.. so it would need the CPU removing and soldering in the PCB instead.. plus it would have to be a 4 layer board.. as it had issues and basically filled the board with around 200 vias.. it just escalates the cost and complexity for a simple project.
So I will just go with easy to solder, as in it wont need the CPU removing from the motherboard, and a simple small 2 layer low cost board.. It will use my STFM DUALTOS boards, and can use 104/206 ROM's. Its pretty much the same arrangement as the V2.3 booster has.

Looks great. Just wondering how you were planning on programming the 22v10s since they are smt?

I need to order some of the SMT chips and make sure they actually match the PCB footprint before I consider heaving ordering a few of these things, as no doubt it is different...

Re: exxos blog - random goings on
Sorry if this sounds silly but wont you have to solder them twice then? All the soic to dip adaptors I can see are solder type.
Unless you've found something interesting adaptor wise?

Re: exxos blog - random goings on
I have most of the parts from my video adapter board now.. I forgot to order some chips so will do that now...
Next I need to try and work out where I got to with the RTC boards...
