U-Micro Advert - September 1982
From Practical Computing
U-Net: Professional-standard micronetwork software
U-Microcomputers, or more commonly U-Micro, started out in the late 1970s as the factory-appointed distributor of Ohio Scientific's range of machines for the north and midlands regions of the UK. Products included the Superboard II and Ohio's larger C3-B.
By the early 1980s it had become a manufacturer of software and hardware products for the Apple II, with this advert in particular making the claim that the company made more Apple cards than Apple itself.
Hardware included boards like the U-Z80 second-processor card for £95, which is around £470 in 2026, or a £195 eight-port RS232 serial interface for plugging in either a lot of printers, or terminals.
In this advert the company has diversified again into networking, with a product known as U-Net.
There's no mention of the underlying technology, although curiously all the supported micros - Apple II, AIM 65, VIC-20, Acorn Atom and the BBC Micro - were all machines running MOS Technology's 6502 processor.
U-Microcomputers would later become more famous for its range of high-specification 68000-based hardware, whilst U-Net is now better known as a type of convolutional neural network used in biomedical imaging.
