 |Geoff Graham'​s ASCII VT100 Video Terminal modified ​ |Running ​ |A single-chip VT100, based upon the PIC32MX256, a 28-pin DIP. Well, you also need a voltage regulator and some passive components. I modified Geoff'​s excellent construction in some small details. I added yet another LED (+5V), a DC power barrel jack, a different RCA socket, a different and less anemic 3.3V voltage regulator, jumper blocks for RGB color selection, a D-sub connector and a MAX233. I allowed the PCB to be larger (100×75 mm) and single-sided. I had to add a few wires on top. I used Geoff'​s software unmodified. I actually built two and bought a PICKit3 for $10, chinese copy for sure, but working!

-|Geoff Graham'​s Colour Maximite ​ |Running ​ |A very capable, single-chip BASIC computer, based upon the PIC32MX795 and with Graham'​s MMBasic. The PIC32 is a 100-pin 14×14 component. Quite easy to solder (or within reason for a beginner) if you listen to or read good advise! \\   \\ I have built four Colour Maximites. One with MMBasic, one with RetroBSD, one with something else(?) and one just for fun (or for give away). I got overconfident when I built the fourth computer. I dropped the PIC, picked it up and soldered it 90 degrees wrong. All one hundred pins were firmly soldered to the board. ​Irritating! ​I de-soldered the chip using a glass ceramic hotplate at moderate heat. I could lift the chip from the board after a few seconds. Chip and board where not damaged. \\  \\ [[http://​geoffg.net/​maximite.html|http://​geoffg.net/​maximite.html]] \\  [[http://​mmbasic.com/​|http://​mmbasic.com/​]] \\  Or why not try BSD UNIX (RetroBSD)?
