Mini Boot Loader

Changed:

<
<

For RAM only Membership Cards you need some kind of bootstrap loader. To type in a monitor or even BASIC or FORTH is nearly impossible. Serial EEPROMs in DIP8 packages are cheap and easy to get. But you still have to use the front panel to type in the boot loader itself (this is the first-stage boot loader).

The "patched on MC PCB" boot loader takes about 25 s for 32 KiB, the DB25 variant takes about 29 s. For the sources see https://github.com/spyren/RaspiElf/tree/master/eeprom
