* We did a [https://www.youtube.com/playlist?list=PLn__0BqzWEWPk0-VW3kEpMNA81sIbhj6n YouTube video series on this card].

<video type="youtube">hwnvghxc5nU</video>

== Features ==

* Includes VGA, PS/2 and USB-Serial converter
* Enough Internal SRAM to make small (16KB) BASIC computers

=== Limitations on MultiComp compatibility ===

* Very limited I/O
** Most of the I/O pins are shared with the 16-bit Video
** Would require removing R-packs to gain I/O
* Driver for PL-2303HX USB-Serial doesn't work under Windows 10 (painful workaround)
** [http://www.prolific.com.tw/US/ShowProduct.aspx?p_id=212&pcid=41 EOL Notice]
* No SD Card storage
* No external SRAM but very large SDRAM (not supported yet in our builds)
* Would require a mod for serial hardware handshake (there's a pin or two free on the I/O which could at least do RTS)

=== Additional Features ===

* On/Off switch - nicer than plugging/unplugging DC power cable
* 4 pushbuttons
* Four digit 7 Segment Display
* IR LED
* Buzzer
* A/D with SMA connector

== Multicomp Builds ==
