From the various terminal manuals i could figure out some special keyboard functions, that work on the Topper too. For example: Ctrl-Shift-V performs a reset of the whole system (cold-start). The Topper has no Reset button. I found only one document where both the Topper I and Topper II are mentioned. It says: Topper I 64k CP/M 2.2 machine and IBM 3270 compatible terminal Topper TT 64k CP/M 2.2 machine and Burroughs compatible terminal The system disks from the Maslin archive are both for the model Topper II. They do not work on my Topper I. The machine reads something from this disks with no boot- or disk-error, prints some cryptic characters on the screen and seems to hang. It should ask me if want either - Command mode - CP/M mode - Terminal mode Rolf --

A couple of years ago (2019) you were in contact with somebody on the vcfed.org forum. He had some disks for a Beehive CP/M machine which turned out to be for the Topper. For what model exactly wasn't be able to figured out. Another guy found the "Beehive International Topper Diagnostic System V1.1 Disk" among his Osborne stuff. The disks should be send to you for imageing. I hope this has be done. I'm still looking for the boot disk for the Topper 1. Rolf --
