Re: whole board with 74LS

I used the HCT kind; but Walter built a board using just LS parts: https://forum.gigatron.io/viewtopic.php?p=1734#p1734

Re: Double your RAM:

hi all, I finally made the 64k upgrade. I decided for a different solution, I put a socket that can be used for both 32k and 64k chips. Since I hadn't a 32 pin socket (and frankly I'm too lazy to remove a 28 pin socket if I can avoid it :lol:) I decided for a Frankenstein socket: I cut a portion of ...

Re: Gigatron vs. Arduino Uno

When I connect my software (or any other terminal software) through the (usb)serial to the Uno board I receive some weird chars (i.e.: "p°W8(ÓñS[¹$ß¡‹™[u"). If I send any ASCII char to the Arduino, the X1 red LED blinks but nothing happens. First get the serial communication working. Unti...

Re: Gigatron vs. Arduino Uno

...I think there's something wrong on the Arduino Uno <--> Gigatron link. Or the Uno board is someway bad. I've seen your emulator can directly control the hardware so I did a try. Some info are definitely sent to the Arduino (I can see the X1 and L lights blinking) but whatever the command I send t...

Re: Gigatron vs. Arduino Uno

I suppose it's just a matter to upload babelfish on Arduino Uno (I got it from the \Contrib\pkupper\BabelFish folder and I compiled and uploaded to the Arduino Uno)... Am I right? The Uno is connected to the Gigatron as shown in the tutorial picture (4 wires). When they're connected together the &qu...

Re: how to compile the ROM

well, the loader_config.ini on my PC is a little different, just few lines: [Comms] ; case sensitive BaudRate = 115200 ; arduino software stack doesn't like > 115200 ComPort = 2 ; can be an index or a name, eg: ComPort = COM5 Timeout = 5.0 ; maximum seconds to wait for Gigatron to respond GclBuild =...

Re: gtBASIC

The way to fix it, is to compile the source yourself on your own specific hardware/OS, relying on outdated pre-compiled executables is fraught with dangers, (even if I compiled them). The problem is that YOUR executable works fine, while the one I compiled on my PC doesn't, LOL However no need to b...

Re: gtBASIC

Do you mean the Visual C++ redistributable? I installed both x86 and x64 (2017 - 14.16.27033)... Yes, the redistributable contains the CRT and whatever other DLLs/LIBs your current version of Windows and Visual Studio requires, (i.e. STL, C++, etc). Did you download the correct one for your version...

Re: how to compile the ROM

It's pretty simple, git clone or download the gigatron-rom repo, type "make dev.rom" on Linux or MacOS. For Windows you'll need a Linux/Unix compatible make to do the same thing, (or you could convert the makefile to nmake format and use nmake), I used chocolatey to download equivalent Li...

Gigatron vs. Arduino Uno

hi guys, I was wondering how you can control the Gigatron by the Arduino Uno sending strings through the serial (USB) port of Arduino. I wrote a very simple program that allows me to send whatever char from my Win7 PC to the Arduino through its COM port, by the USB cable. However I suppose I should ...
