I like to have one for me if not too late.

Sure a 20 pieces batch will be made there will be one for you. But not this month cause I'm far away (March  ;) )

Ah hell, have I declared interest? I think not :D What is the cost?

Hi!


To everyone who is interested in this MX4 card...


The routing on eagle is progressing but I've got very little spare time. I hit a problem when I realized the battery in the RTC module is now (2015) almost empty, I measured the voltage of a few of them.


Hence I'm changing a bit the design, you'll get either a brand new 3v battery or even a socketed batt like on PC mainboards. Howver this implies that I'm going to drop the "standalone" capability, so that the card will be meant to be plugged on a MX4 in parallel with a romboard (MegaFlash, X-Mem).


Stay tuned.

Sounds good to me. Still wanting this one.

Hi there,


Eventually got some spare time and completed the design of the board.  This is a tight fit on the MX4 format.
You can check the updated FAQ in the first post, but what you will get in short:
  - usable as a standalone or with a MegaFlash / X-Mem, on the full CPC range
  - user replaceable standard lithium button cell (big improvement over the original design), life should be >10yr
  - MX4 format
  - corrected software without the Y2K bug and "translated" in english or french





What remains to be done is ordering the boards, components and soldering.
Keep an eye here if you want one.

CraigsBar

Indeed I want one :)


Edit: No 2 actually, one for my 4128plus and one for my JustCPC :)

When?
I would say after I order the pcbs, solder one to find out I made some stupid mistake, re-order the pcbs, then they get lost in the mail, then...  :D

1 for me please, too.
