Which version of Luciferin/Bootloader were you using? Be sure to have at least V1.4. V1.5 is available for some time now. The latest version is V1.6 and can be obtained directly from me (email) or E3B.
As about getting the machine to boot again: Connect an Amiga Mouse (the standard port) to the machine, press and hold the middle* mouse button, turn on the machine. The machine should boot up normally now. Then install the new version of Luciferin and a new bootloader with LMBMMB support. Also, clear the contents of the flashrom in case the previous owner had flashed stuff that is not compatible with your machine.
If this still doesn't work (or you don't have a mouse with three buttons), contact Michael Boehmer on instructions how to boot the machine with the Algor card installed (you need to set a "jumper" at two certain pins of the Expansion port, get detailled instructions first -- and please don't fiddle with the JTAG port!).
* Due to a mistake from my side, the LMBMMB and MMB bootloaders were mixed up *in the very first software version released with first batch of Algor cards*. I am sorry for this error and take the full responsibilities.
