Sorry to hear you had a funeral to attend. They tend to grab attention from everything else. No pressure, this is just a retro hobby after all.

Sounds like a great update, your floppy adaptor sound like a much neater (and reversible) solution.

hello People,

I have just completed the first COMPLETE build of the 2 MegaByte RAM card and connected it to the bus extension board.

I will soon build the cable and begin testing it, along with the soon to be built SD card adapter for the SPI interface.
Lets hope all goes as expected and then I can build more for those who want it.... ;D

Attached is a close up of the card.

Any chance to upgrade it to 4 MB?

I have no intention yet to upgrade to 4 MB.

However you can never discount the possibility ;D

Oh, no problem. There is somebody else making the 4 MB ones.  :)

Hello people,

I have tested my first complete build and it appears to work as expected.
I will do a few more tests to put it through its paces and should not find any problems at this stage.
hopefully, my next post should then be one in which costs are determined and orders can be taken.
