Hello Tony I am interested in selling a Master 128 computer. I was referred to your site by a friend in computing. I thought that I might boot it up again, and with the use of its RS232 port I would use it as a controller for a variety of electronic projects (such as are sold at Tandy's or in Australia Dick Smith Electronics's). But I have become more interested in traditional photography. It is a BBC master 128 computer. And I have a circuit board to upgrade it to a 512. I have the 2 manuals that go with it, each is nearly an inch thick, and I have the manual from the computer it was derived from, the BBC B, again nearly an inch thick. The earlier manual heavily complements the Master 128 manuals; it is a great shame it wasn't sold with them. It would have saved me some grief. I also have a workshop manual for it including wiring diagrams and diagnostics. I have two single 5 and a quarter inch disk drives plus a heap of original discs and software. I have a stack of computer magazines, over 2 feet tall, which include programs and electronics projects for interfacing all sorts of devices with it. I used to use my colour tv as my monitor and an Epson FX 80 dot matrix as my printer. Regards David Constable
