Hello TTram :D

Had a fiddle with Ultrasatan. If I keep it turned off until I get to desktop then launched the driver, it seems to work fine. However, if it is turned on and I power on the STE, it seems the lock-up just after the Atari logo. There is some flashes on Ultrasatan but nothing else happens at all. It boots fine in EMUTOS, so not sure this is a hardware issue.. not sure..

EDIT:
Ah its got ICD driver on the drive. So I need to get rid of that next.. (I just booted with the stock machine 68000).

Haha! Well done!

So they stiffed you at the assembly house?

@stephen_usher your DIR pin comment was closer to the mark than it should have been! :lol:

Well done @exxos - great to have that option for the STE (and so probably the easiest install for the accelerator on any ST as a result)!

Thanks guys :)

Got a odd crash issue to figure out next. I ran GB6 for a couple hours and was fine though.. I am hoping it's something simple like I'm using the plastic CPU at 50mhz.. it also seems a bit slower than the ST536 which is odd.

Did a quick test as to why integer division is only showing 1660% when it should be 1728%

Currently I don't have anything in the auto folder..

So I load GB6 and with the blitter DISABLED I get 1728%.
Then with the blitter ENABLED I get 1660%.
So I DISABLE the blitter and it still shows 1660%

:WTF: :shrug:

As I side quest, I wondered what would happen if I put BLT_FIX to run from STram vs TTram.. Was a little bit of a difference...
