Its claim to fame was its combination of Intel 8088 CPU with PC\/AT bus compatibility and integrated serial terminal console capability, making it a flexible, low-cost option for hobbyists and small offices. Although it never achieved mass-market popularity, with around 400 units made mostly for in-house use, it was important historically as one of the first DIY kits bringing near-PC functionality to the hobbyist and academic communities, bridging the gap between simple SBCs and full PCs in university vintage computing collections. Its main OS was CP\/M, and it had planned support for MS-DOS, highlighting its transitional role in early personal computing.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Manufacturer<\/strong>: Micromint<\/li>\n\n\n\n<li><strong>Type<\/strong>: Single Board Computer<\/li>\n\n\n\n<li><strong>Release Date<\/strong>: 1979<\/li>\n\n\n\n<li><strong>Cost at release<\/strong>: usd $1,895 (CAD ~$9,000 adjusted for inflation)<\/li>\n\n\n\n<li><strong>MIPS<\/strong>: 0.5 (500 KIPS)<\/li>\n<\/ul>\n\n\n\n<h3 id=\"hardware-specifications\" class=\"wp-block-heading\"><span class=\"TextRun SCXW36078203 BCX0\" lang=\"EN-US\" xml:lang=\"EN-US\" data-contrast=\"auto\"><span class=\"NormalTextRun SCXW36078203 BCX0\">Hardware Specifications<\/span><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>CPU<\/strong>: Intel 8088 microprocessor, 4.77 MHz clock speed<\/li>\n\n\n\n<li><strong>Memory<\/strong>: Typically 256 KB RAM expandable; includes ROM (up to 64 KB)<\/li>\n\n\n\n<li><strong>I\/O<\/strong>: Integrated serial and parallel interfaces, floppy disk controller<\/li>\n\n\n\n<li><strong>System board<\/strong>: Single 9 x 12 inch, 5-layer printed circuit board<\/li>\n\n\n\n<li><strong>Clock generator<\/strong>: Intel 8284 generates system clock and reset signals<\/li>\n\n\n\n<li><strong>Operating Systems<\/strong>: CP\/M-86 and early MS-DOS support<\/li>\n\n\n\n<li><strong>Compatibility<\/strong>: IBM PC-compatible bus and hardware architecture<\/li>\n\n\n\n<li><strong>Expandability<\/strong>: Multiple I\/O expansion slots for peripherals<\/li>\n\n\n\n<li><strong>Power supply<\/strong>: External power supply unit<\/li>\n<\/ul>\n\n\n\n<h3 id=\"operating-system-programming-languages\" class=\"wp-block-heading\"><span class=\"TextRun SCXW136206418 BCX0\" lang=\"EN-US\" xml:lang=\"EN-US\" data-contrast=\"auto\"><span class=\"NormalTextRun SCXW136206418 BCX0\">Operating System &amp; Programming Languages<\/span><\/span><span class=\"EOP SCXW136206418 BCX0\" data-ccp-props=\"{&quot;335559685&quot;:0}\">&nbsp;<\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Operating System<\/strong>: CP\/M-86 operating system, an early OS for 16-bit microprocessors.
