Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

OK I made the capacitor modification to my board and the VGA/keyboard is working fine now, thanks.

As far as compatible SD cards. I plugged in my 512MB SanDisk Micro into the Micro/SD adapter, then formatted it with simple FAT, then copied all the Maximite files I could download onto the Micro card. My Maximite was able to load and run all the programs from my SD card.

Kingston 2GB SD (part number SD-M02G) works.

Hi,

A Transcend 4Gb SDHC 6 card works fine in my Maximite.

Given this is my first post please allow me to introduce myself a little, Basic started for me with a ZX81 and then a Apple IIe and c. Around the time of the 386 I went to PC's and now my choice of GUI OS's is Linux/Ubuntu. It is rather good to be back to a command prompt.

I have a couple of project's lined up for the Maximite however for the moment I have been simply testing some of its capability.


Cheers,
Anthony.

Maybe the problem with the SD cards is not the cards themselves but an issue with the Maximite. When I built the WIB, i had the same problems that some of you guys are having with the Maximite. It came down to the 3.3v regulator output voltage being slightly low. I changed the resister bias and to give me a voltage as close to 3.3v as possible. Some SD cards have a very fine voltage tolerance (window).
I just thought I'd share this experience with you in case it may help.

I have added this here as well to make it easier to follow the topic.

One of the issues of Silicon Chip that carries part 3 of the Maximite, May-2011 page 62, has an article about Memory Card Compatibility issues
