The UK101 was a version of the OSI 600
Superboard, similar to the one shipped in the C1-P, modified for use in the UK
and Australia. The hardware was nearly the same, the system and BASIC ROMS
began as modified versions of the OSI ROMS.
Thomas Buescher has a written nice OSI history overview here. Browse an OSI product pamphlet page 1, 2, 3, 4, 5 .
My introduction to OSI came in 1978, I was fortunate to get a C2-8P system, which looked something like this. It had an OSI 500 CPU board with 4K of 2102 static RAM 1Mhz 6502 & BASIC in ROM, a 540 monochrome composite video board with 2Kx7bit RAM & a 64x32 display + cassette interface, and a 420C 4K static RAM board using 32 2102A 1Kx1 static RAM chips, and a 9" B/W composite monitor. Total price was nearly $2000. Today you can emulate this system for free on your PC!
