As far as I know, the EP4CE22 core board is out of stock. SX-2, as a clone of SM-X, deleted the HDMI interface, and the later SM-X HB also did not have an HDMI interface. Even the latest SX-E uses a 55k LE FPGA and does not have HDMI. They need an external VGA to HDMI module to achieve HDMI output, just like the old uMSX. You have to power the conversion module and manually connect the audio cable to the conversion module, which is too troublesome.We all know that Tang20k, as an external MSX, already supports HDMI output, so some people may ask why there is no OCM based on Tang20k. Currently, hra is developing that, which requires a lot of time and experience. OCM is a huge project and it is not an easy task.Therefore, I designed uMSX HDMI to solve all the above problems.What makes it special?The latest deluxe version of uMSX has the following features:Truly professional 4-layer PCB layout and routing, independent power layer and ground layer, minimize noise, and greatly improve video and audio quality.Support HDMI and VGA output at the same time, the picture quality exceeds the old version of uMSX v3.80. And its HDMI interface supports audio transmission, which is very friendly for modern monitors or TVs.USB or PS/2 keyboard support, compatible with almost all USB keyboards, based on the hidman project.USB or PS/2 mouse support, through the MSX Nano Mouse project.Independent audio power supply circuit and headphone amplifier provide excellent sound quality, with a disc potentiometer, and adjustable volume.Bluetooth controller support, based on the BlueRetro project.Bluetooth audio support, through an external Bluetooth controller.Optional tablet or laptop form, uMSX Tablet or uMSX Laptop.Optional video DAC, weight resistor network or independent DAC video chip.MSX2+ Compatible , Modified esemsx3 (OCM 1st Gen) OCM_PLD v3.9.2 latest firmware, provided by KdL, supports smart commands.Support modular sound cards, including MSX-Audio, Y8950, YM3526-OPL1, YM3812-OPL2, YMF262-OPL3, YM2151-OPMUNAPI standard Wi-Fi support, based on OCM SDBios.The uMSX HD Logo will be displayed at startup. 99.00 USD https://denjhang.bigcartel.com/product/u1-sx-hd-umsx-msx2-high-definition-console https://assets.bigcartel.com/product_images/423004341/F4BAFAD58A4AE42CC4CD84E2A52E363A.png https://assets.bigcartel.com/product_images/423112230/ff9de5041b9909764d3fb7fd5bc154e1.jpg,https://assets.bigcartel.com/product_images/423112227/e28f88383c68709f47cab7cc719c77cb.jpg,https://assets.bigcartel.com/product_images/423004338/8739A34D2162FEC0D902465032D03780.png,https://assets.bigcartel.com/product_images/423112221/6a5ab727b43dc8af33ea9316b874b45d.jpg 118815924 new in stock
