Microcalculatorul MS 100

MS 100 a fost un microcalculator românesc proiectat la ITC Bucureşti şi ITC Timisoara şi intrat în producţia de serie la Fabrica de Memorii din Timişoara (FMECTC), în cursul anului 1985. MS 100 a avut o arhitectură construită în jurul microprocesoarelor 8080, cu circuite Intel din familia acestuia, fiind în practică un sistem multiprocesor pentru aplicaţii diverse. Viteza de lucru a acestui sistem era de 250.000 operaţii /secundă, iar memoria RAM era de 64 KB.

MS 100 dispunea de interfaţă serială, care utiliza standardul de comunicaţie RS 232C, şi de o interfaţă paralelă. Prin portul paralel se putea conecta o imprimantă, iar prin portul serial un videoterminal DAF 2020, la rândul său microcalculator bazat pe microprocesorul Z80, cu 2 kB memorie RAM, 10 kB memorie PROM şi 24 kB memorie de ecran. În regim text, videoterminalul putea afişa 25 de linii a câte 73 de caractere, iar în regim grafic, 512 × 390 pixeli.

MS 100 mai avea incorporată în carcasă o unitate dublă de discuri flexibile de 8 inci.

Din punct de vedere software, MS 100 a fost un sistem compatibil CP/M. Dispunea de asambloare (ASM80, M80, MAC), compilatoare (BASIC, PL/I, FORTRAN, COBOL, PASCAL, FORTH), interpretor BASIC şi diverse alte aplicaţii (DBASE II, MULTIPLAN, WORDSTAR, DATASTAR etc.).

Un exemplar al microcalculatorului MS 100 se află expus în Muzeul Banatului din Timişoara, alături de câteva dischete cu programe specializate pentru acesta.
