It uses a real (non-emulated) Z80 processor, an AY-3-8910 sound chip, and a programmable CPLD as the ULA. Sizif-512 is a modern version of the <strong class=\"def\">Harlequin 128<\/strong> project and the motherboard for the <a class=\"def\" href=\"https:\/\/mumio.dev\/sklep\/ZX-Spectrum-Neo\">ZX Spectrum Neo<\/a> computer.   <\/p>\n<p class=\"def\">This kit includes a DIY PCB with the most challenging SMD components pre-soldered and programmed. This saves you from soldering difficult chips or needing programmers for them. Assembly simply involves purchasing and soldering the remaining parts.  <\/p>\n<ul class=\"def\">\n<li class=\"def\">CPLD Altera EPM1270T144 &#8211; soldered and programmed<\/li>\n<li class=\"def\">SN74CB3T3245PW buffers<\/li>\n<li class=\"def\">SST39SF040 &#8211; programmed<\/li>\n<\/ul>\n<p class=\"def\">Sizif-512 project page with documentation: <a class=\"def\" href=\"https:\/\/github.com\/UzixLS\/zx-sizif-512\"><span class=\"def\">https:\/\/github.com\/UzixLS\/zx-sizif-512<\/span><\/a><br class=\"def\">More about Sizif-512 and ZX Spectrum Neo: <a href=\"https:\/\/mumio.dev\/en\/zx-spectrum-neo\/\">https:\/\/mumio.dev\/zx-spectrum-neo\/<\/a><\/p>\n<p class=\"def\">\n","protected":false},"excerpt":{"rendered":"<p>Sizif-512 DIY (kit 1) &#8211; board with soldered and programmed Altera<\/p>\n","protected":false},"featured_media":5852,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[34],"product_tag":[],"class_list":{"0":"post-6263","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-sizif-512-diy","8":"first","9":"outofstock","10":"taxable","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/mumio.dev\/en\/wp-json\/wp\/v2\/product\/6263","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mumio.dev\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/mumio.dev\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/mumio.dev\/en\/wp-json\/wp\/v2\/comments?post=6263"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mumio.dev\/en\/wp-json\/wp\/v2\/media\/5852"}],"wp:attachment":[{"href":"https:\/\/mumio.dev\/en\/wp-json\/wp\/v2\/media?parent=6263"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/mumio.dev\/en\/wp-json\/wp\/v2\/product_brand?post=6263"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/mumio.dev\/en\/wp-json\/wp\/v2\/product_cat?post=6263"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/mumio.dev\/en\/wp-json\/wp\/v2\/product_tag?post=6263"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
