 ECB RAM Floppy was developed by Dr. Wolfgang Kabatzke. The original documentation for this project is on the [[n8vem-pbwiki-archive:0:35845334:48860720:34743680:page-ECB-RAF2011%20R11|n8vem-pbwiki-archive.]]
+The ECB RAM Floppy appears to be based on Gerald Ebert's SRAMDISK https://hschuetz.selfhost.eu/ndr/hardware/neu/speicher/ram/

 ====== The ATTINY13-20 ======
-IC23 is an ATTINY13-20. It is easier to use a Microcontroller for the activity function then a retriggerable monoflop with external capacities and resistors. To program this use the HEX-File file here: [[https://retrobrewcomputers.org/lib/exe/fetch.php?media=boards:ecb:ramfloppy:firmware:attiny.zip|:boards:ecb:ramfloppy:firmware:attiny.zip]]
