Re: BLITTER RE-CREATION THOUGHTS

Posting some GB6 benchmarks to show where we are currently. We think that the Blitter is under performing due to how the state machine works in the core and we are looking into this. We did a test of the Blitter at 16MHz to see how it was behaving but it created screen corruption. Managed to get the...

Re: Flashy Clock - Yet another DEV board

Made one of the v3 boards yesterday and am building another today for Exxos so we can do initial tests and firmware.

Looks pretty small in the STFM. No stacking sockets.

Re: Atari lost all power after installing 6 TOS 1.04 ROM chips.

Hi. Sounds like you have quite a few upgrades going on at the same time. TOS and Marpet installs.

With the original chip back in place is the Market working? Just to rule that upgrade out.

Re: BLITTER RE-CREATION THOUGHTS

:cheer: All that Glitters is golden :cheer: We have a booting STFM with an FPGA Blitter Board (Sparkalaphobia). Now although it boots, we are getting test results its performing at 58% of a stock Blitter. We need to do some more work to get it up to normal speed. However that said we are now truly o...

Re: BLITTER RE-CREATION THOUGHTS

Just got these two glittery things made up. These are a newer revision of the original with the regulator fixed from the incorrect eagle footprint and the patches from the first one built into the board. IMG_4225.jpg Will sort out the core pin assignment out and load it into the FPGA probably tonight.

Bodge capacitor and firmware tweak later...Finally booted up to TOS206... passed over 40 loops (YAART 4MB) so now the board is stable.

No time tonight to work on the basic IDE firmware... but at least its now booting :)
:thumbup: - snap. Trudie number two is also booting

The ST keys are as follows (from my initial measuring): 1.33U - Left Shift 1.66U - Tab, Alternate, Caps Lock, Right Shift, Backspace, Help, Undo 2U - Control 11U - Spacebar After remeasuring, as I have been working on the cherry keys placement on the board, I noticed I got my initial measurements w...
