A Synertek Systems Synertek SYM-1" and is a 6502 Development system, c.1975, in original case with original booklets including a copy of Microchess a chess playing Program by Peter Jennings, SYM Reference Manual; Programming Manual, Programming the 6502; 6502 Application Book, in original black plastic case. https://en.wikipedia.org/wiki/SYM-1 The SYM-1 was a single board "trainer" computer produced by Synertek Systems Corp in 1975. It was designed by Ray Holt who also designed the first microprocessor chip set used in the CADC for the F-14 Tomcat. Originally called the VIM-1 (Versatile Input Monitor), that name was later changed to SYM-1. The SYM-1 was a competitor to the popular MOS Technology KIM-1 system, with which it was compatible to a large extent. Compared to the KIM-1, enhancements included the ability to run on a single +5 volt power supply, an enhanced monitor ROM, three configurable ROM/EPROM sockets, RAM expandable on board to 4 KB, an RS-232 serial port, and a "high speed" (185 bytes/second, the KIM-1 supported about 8 bytes/second) audio cassette storage interface. It also featured on-board buffer circuits to ease interfacing to "high voltage or high current" devices. One rather distinctive capability of the SYM-1 was its ability to allow an oscilloscope to be added to provide a 32 character display under software control. As explained in Chapter 7 of the "SYM Reference Manual", the vertical input, ground and trigger input of the oscilloscope were to be connected to the "Scope Out" connector AA on the SYM-1 board. The "Oscilloscope Output Driver Software" code provided in this chapter of the manual was to be entered into the SYM-1's memory and executed to enable the oscilloscope display. This code provided control of the oscilloscope display, as well as a rudimentary character set. Resistors R42 and R45 were to be adjusted to refine the displayed image. Synertek sold ROMs which could be installed to add the BASIC programming language or a Resident Assembler/Editor (RAE). Synertek contracted with a company called Eastern House Software to port their Macro Assembler/Editor (MAE) into an 8 KB ROM. The author of MAE, RAE, and another version sold by Skyles Electric Works was Carl Moser. MAE was sold in various forms not only for the SYM-1 but also for other 6502-based computers including Commodore, Atari, KIM, and Apple. Other forms of MAE included a cross assembler for 6800 and 8085—and an offering of these cross assemblers was planned for RAE. One of the more subtle features of the SYM-1 was the use of a look up table in the low memory of the 6502. This provided a vectoring function in its operating system to redirect subroutine calls to various input and output drivers, including interrupt servicing. Users were able to develop their own interface routines, and substitute new vectors for the original vectors in the startup UV-EPROM. This seamlessly maintained the normal operation of the board's monitor and languages such as Synertek Systems BASIC. One of the later home/education computers that used this concept extensively was the BBC Micro produced by Acorn Computers in the UK. Some of the other computer designers of this era failed to grasp the significance of this elegant use of vectors to the software mapping of new developments in hardware.

Sir John Lavery (Irish 1856-1941) Hyde Park Corner, 29th vember 1934 Oil on board Signed and titled lower left 60.5 x 50cm (23¾ x 19½ in.) Provenance: Private Collection, France Exhibited: Liverpool, Walker Art Gallery, 1935 Glasgow, The Glasgow Art Club, 22 February 1935 - 30 March 1935, . 3 To celebrate the marriage of Princess Marina of Greece and Denmark and Prince George, Duke of Kent. Sir John Lavery was born in 1856 in rth Belfast but was brought up in Scotland. Lavery studied at Haldane Academy in Glasgow and moved to Paris in the 1880s to continue his studies at the Academie Julian. On his return to Glasgow in 1885 he became close friends with a group of artists dubbed the Glasgow Boys, which included James Guthrie (1859-1930), Arthur Melville (1855-1904) and Edward Arthur Walton (1860-1922). Lavery established himself as a prominent society portraitist after his move to London in 1896 where he also took a great interest in painting contemporary everyday scenes and events. In 1880 he was commissioned to paint the state visit of Queen Victoria to the Glasgow International Exhibition. This Royal patronage continued and in 1913 Hugh Spottiswoode commissioned Lavery to paint the family portrait of King George V. The work was exhibited at the Royal Academy and later presented to Queen Mary by the artist. In 1921 Lavery was knighted and elected to the Royal Academy. The present lot captures the procession at Hyde Park corner to celebrate the wedding of Prince George, Duke of Kent and Princess Marina of Greece and Denmark. They were married in a Church of England ceremony at Westminster Abbey on vember 29, 1934. The ceremony was followed by a Greek Orthodox service at the Private Chapel in Buckingham Palace. The work was exhibited at the Glasgow Art Club in 1935 alongside other oil paintings by Glasgow Art Club members. The works were hung in the Club rooms in Bath Street. The exhibition was described as 'interesting, illustrating various approaches to art expression.' The present lot was described by one critic at the time as a picture with 'remarkable verve and dexterity. The great crowd is suggested by the merest articulation, and with a table effect of perspective, the Royal carriage and procession in the foreground.' The critic was recorded writing in the Scotsman on 26th February 1935, his name was never recorded. The wedding was the first royal wedding ceremony to be broadcast by wireless. The service was broadcast internationally and loudspeakers allowed spectators outside of Westminster Abbey to hear the proceedings. Princess Marina wore a white and silver silk brocade designed by Edward Molyneaux and the couple honeymooned at Himley Hall in Himley, Staffordshire, England, the country estate of William Ward, 3rd Earl of Dudley. Please note this work is oil on canvas laid down to board
