... disable Interrupts in the guest setup. For some reason the used CP/M 2.2 i took from the Z80 MBC2 project the guest is also based on doesn't expect interrupts to be enabled and acts strange. Senfsosse from the Forum64 discovered that over here

On another note, the PDP8E guest is coming along, i will release it on Github when it can at least boot into a papertape loaded programming language. If someone has an image of a papertape BASIC, hit me up!

Added some files, a Linux PC precompiled version for the curios, the u2f for the ones that want to hack together one.

And there is a groupbuy over on Forum64 if you are interested: https://www.forum64.de/index.php?thread/159630-sammelbestellung-the-seventies-board-beta/

You can also send me a PM over here if you don't want to register over on Forum 64.

By the way, is it normal that new projects get pestered with spam and phishing attacks? This is my first release over here and i wonder... two PMs from accounts that pretend to be Hackaday till now and a "coldcall" mail from a certain PCB house.
