Most implementations used about 2k of RAM for the entire package: line editor and interpreter. The TRS-80 Model 1 even came with an enhanced version (4k) of the language. Flavors of Tiny Basic were available for wide range of chips (some of which even had the language burned into them) from the Intel 4004 (quite a challenge since its entire address range is 16k) to the Z80 and oddball chips like the RCA 1802, Signetics 2650 and the National Semiconductor SC/MP. Tiny Basic, for those who may not know, came into being in the mid 1970’s for use in very low power microcomputers. I have extended it to include these features. The original Arduino Basic did not include the ability to save or load programs nor did it have any control over the screen. Text rendering is done via the tile mode, which has, for now, precluded the inclusion of any graphical statement additions to the Basic (which I named ArdBasic, short for Arduino Basic.)

Now, the XGS PIC has two graphical modes: bitmap and tile.

He left the I/O generic enough for me to, quite literally, plug in the calls to the keyboard and graphic driver API’s that Nurve supplied.

Field allowed for serial I/O to a terminal OR for use on an Arduino with keyboard and screen. The architecture of the interpreter is smart and was easily adaptable to the XGS PIC. The Nanode modification added some features for real world interfacing to temperature sensors and a few other things. Called Nanode Basic, it was a modification of a Tiny Basic someone (Mike Field – crammed into an Arduino. So, after some searching and pouring through code, I found something for the Arduino.

Well, 256k is more than enough for the Tiny Basic code and the API libraries, it’s the 16k RAM that makes it tight as this memory is shared between the video and your program. The graphical ability is somewhat between an Atari 7800 and the original NES in appearance.Īlso, memory is tight: 16k RAM and 256k Flash. Talking to each is rather laborious to code, but the API set eases the pain a bit. VGA or Composite video out, really simple audio, SD card interface, Serial communications, two Atari style controller ports and PS/2 keyboard/mouse interface. The XGS PIC is a really funky, game oriented device and, as such, has very minimal specs. Since the XGS PIC has no operating system (whatever code that runs on it BECOMES the ‘OS’, providing all I/O.įortunately, Nurve Networks provided a few very well documented API’s and demos that I could use to supply all of the I/O I’d need. Most, however, did not lend themselves to the kinds of changes I’d need to do to make it work.

Rather than setting about writing the dialect from scratch, I searched the Internet for an open source variation and, boy, are there plenty. The rest of the language is fine, even cool at times. This exercise, however, has reminded me of why I dislike the C programming language. However, there are currently no development tools that actually RUN ON the device, so…I have adapted a dialect of Tiny Basic to run on the board. One of the things I’d wanted to be able to do is actually do some coding ON the device. Since rediscovering the XGS PIC Gamestation board, I’ve been doing some developing for the kit.
