    Found my first computer this week. Nascom 1 (1978 ish) built into a wind up gramaphone case, swappable roms (tiny basic and a monitor IIRC) space for a Phillips EL3302 cassette player (that i also have some where) also found my software on tape. Really need to archive those :) Z80 at 4Mhz , 2KB onboard 1KB video, 1K user. 4K expansion (8x 2114's) #RetroComputing #z80 #nascom

    @ajsadauskas @luca Here's a good article on Hartley Computer: https://ia.acs.org.au/article/2017/acs-heritage-project--chapter-34.html"David Hartley (not to be confused with the British computer scientist of the same name) started his working life in 1966 as a civil engineer with Brisbane City Council. His work later took him to Namibia in southern Africa, where he was introduced to computing while conducting mathematical modelling of rainfall in the vast Okavango river basin, using FORTRAN on an ICT 1500."When he returned to Australia he decided that computing was more interesting than civil engineering. He started Hartley Computer in Brisbane in 1974 to develop software for the accounting profession, on the rationale that accounting could be easily computerised but that many in the profession did not realise that...."The new software was very successful – it was the only software in Australia designed specifically for small accounting practices. Hartley also designed SHEILA (System by Hartley for Entirely Integrated Ledger Accounting) for larger organisations. The venture included building hardware (the Hartley 3900) and an operating system. Both the hardware and the software were very innovative....“The operating system was called RT86, a ‘true pre-emptive multi-user multi-tasking operating system for the 8086 chip. It was launched in 1980, 15 years before Windows PCs had that capability.“Hartley Computer was one of the first mini/PC computer vertical market successes in the world, with ultimately 250 staff and 3,000 sites in seven countries. In the process I became known as ‘the father of computer client accounting’, and we won several awards. The success was killed by hubris and a messy divorce. Big lessons, only partly learned at the time.”

    30 settembre 1988 #accaddeoggiIBM annuncia la spedizione di 3 milioni di personal computer PS/2, successori di PC, XT e AT. Presentati nel 1987, introdussero la Micro Channel Architecture, diversa dallo standard ISA usato dai cloni. Resero comuni i floppy da 3,5" e la grafica VGA, e furono i primi IBM con il chip Intel 80386 e il sistema operativo OS/2, che permise anche l’uso del mouse, diventato poi periferica standard.@computer #retrocomputing #retrocomputer #retroinformatica

    29 settembre 1983#accaddeoggiLancio di Microsoft Word, sviluppato da Charles Simonyl e Richard Brodie, ex Xerox, assunti da Gates e Allen nel 1981. Il 1983 fu cruciale per Microsoft: a febbraio Allen lasciò la vicepresidenza, a marzo uscì MS-DOS 2.0, e il 10 novembre fu presentato Windows, estensione grafica di MS-DOS, che però arrivò sul mercato solo due anni dopo.@computer #retrocomputing #retrocomputer #retroinformatica
