Hi all,

https://p-l4b.github.io/sdcard/
I have a few boards available, tested and ready: contact me if interested.
Thank you,

I have purchased one of these cards from Claudio, and he worked with me to be as sure as possible it would function on my Briel Replica 1 Plus. I am quite happy with my purchase, it has brought much needed life and storage to my Apple 1 clone :)
If anyone in the future is to use one of these with a Briel replica 1 plus, I used the latest model of the Briel replica as of this posting, and the following steps were needed:
Briel Replica 1 Plus:
Jumper 5V from test point near edge connector to pin 1 of the slot connector (Easy mod especially if you assembled the Briel to begin with). I did this on the underside of the PCB.
*Per P-lab, "the modifications of the board need to be applied only to "PCB revision 1.13".:
p-lab SD slot card:
Carefully lift IC 74159 from it's socket, bending out only pins 3 and 4 so they do not contact the socket, and then carefully re-insert the IC
remove both jumpers on the sdcard PCB (1000-1FFF and 16/32K jumpers)
I will let Claudio clarify but it sounds like the next revision might not need the modificaitons listed here.
Hi all,
as anticipated by skate323k137 (a big thank you!!!), with just a few mods it is possible to use Apple-1 microSD storage card with Briel Computers Replica-1 Plus.
Reference guide has been uploaded to the usual GitHub page:
https://p-l4b.github.io/sdcard/
Modifications refer to units already in circulation (PCB v1.13) or currently in preparation (PCB v1.16).
Further changes or improvements will be promptly communicated!
Enjoy! :-)

The documentation looks great, and it was a pleasure to help. I hope many others consider buying one of these [when your next production is done]. The time savings of loading programs with one, vs. over a serial terminal, is incredible. And the command line for finding and running programs is very intuitive, something I never thought I would say in the same breath as "Apple 1 replica." Very well done and well designed product.
