Gigatron Hackers

I am just starting to try and program on the Gigatron. I am sure I saw a memory map somewhere a while back but now I cannot seem to locate it.
My current question is where is the character set pixel map stored and can it be changed ?
I want to change some of the characters appearance.

Thank you. It was low voltage. all working now

so just discovered the 27c1024 is write once. ordered some more from mouser

I am using ROM5a and babelfish from here https://www.dropbox.com/sh/d8v284j9j41bby3/AAB0HwuKrlWOsKBrOrrxWuCUa?dl=0 sd card is formatted FAT32 I was referring to J1 on the ProMicro No shorts on soldering ******* I don't have the SD card ROM installed. Where does that go ? Does that replace ROMv5a.rom ?

I have put together the kit and loaded the cpld code as per page 11 and the keyboard and game port both work great. But when I press ctrl F2 to access the sd card the blinkenlights go out and the power light stars flicking and the screen goes black. is there an sd card restriction ? Or does jumper 1...

Hi @walter,

I would be interested in one of the video repeater kits. I am located in Portugal

I am in Portugal by the way
