- We did a YouTube video series on this card.
Contents
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)
- 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
