The BOTBios software system lets you embed PC .COM files into an EPROM, for execution on an 8088-compatible board, such as the New Micros V25 unit. Bill Bailey (of the SRS) and I had great fun designing and building this system. You can find full details in one of my recent Nuts & Volts articles.
bbios1_0.zip contains a complete package for the BOTBios executable, which runs on the target 8088 system. This package includes docs, a ROM image of a working BOTBios, and source code for building your own version of BOTBios. This is a zipped file, so you will need to run pkunzip on it.
rommkr02.zip contains a complete ROMMAKER package for building an EPROM with multiple .COM images in it, for running on the target 8088 system. This package includes docs and an executable file for building your own BOTBios-compatible ROM discs. This is a zipped file, so you will need to run pkunzip on it.
asic500.zip contains the ASIC (almost BASIC) compiler system. This package can compile BASIC programs into tiny .COM files suitable for embedding in a ROM disc and running under BOTBios. This is a shareware system available through several places on the Internet, but I'm including it here for your convenience. This is a zipped file, so you will need to run pkunzip on it.
