Flegmatik's build

Post by flegmatik »

A new Atari was born today.

I had a bit of a problem with programming of usable ROM, I forgot to byte-swap the ROM files so was stuck with a white screen for an hour or two. It is wonderful what an hour of badminton with a kid outside does to one's brain.
After the game, I checked ROM files, slapped my forehead and byte-swapped the file. 2 minutes later, Atari booted TOS 1.04 with success. After that, I reprogrammed EPROM with Emutos 1.2.1 and TOS 1.04, both are booting fine.

Regarding DAC STV8438, is it normal for that chip to run really hot, ~50C?

Today I've fitted 16MHz BOOSTER 2021 edition, burned 256K Emutos on EPROM, implemented a partial audio fix, plugged in the Blitter chip, added S2 Midi board and played some games.

I tested MIDI sound with Bomberjack and it works as expected.
