[cctalk] Beehive Topper help needed

Hi folks! Is there anyone out there, who can help me with my Beehive Topper CP/M machine? The machine starts up with his self-test going o.k. Then it requests for the boot disk or pressing RETURN to start the Monitor V2.0 program. The Monitor program seems to work o.k. Booting a disk (written from the images out of the Maslin archive) puts some cryptic characters of the screen and hangs the machine. The images are for a Topper II, mine is a model Topper. Is this the problem? I have found very very little about the Topper machines, no manuals, no software, no schematics. R. Harten --
