Re: VHDL CACHE ?

I think that here is some confusion about auto modifying code. In case of 68030 there is problem of modifying code, which is only some 2-20 bytes ahead. But that is already in CPU's pipeline, so will not execute properly. I called it pipeline bug - and I found it in at least 10 games - like Infestat...

Re: Problem with autoboot.

None of your patches is even remotely good. Here is UK TOS 2.06 with dual IDE boot patch - so will autoboot from twisted or regular IDE cable.

Re: Better late than sorry

It seems that you have some bad experiences with 'competition' - since mentioned it 3 times in introducing :D Yep, I can say that there were and probably still are some very bad things in 'competition' among people dealing with retro things - SW and HW too. I was never interested to go on some conte...

Re: Whitewater Madness STE game with source

I thought that it was shipped with some STE machines in bundle package.
And it is available at Atarimania years ago. Checking - it was 'WIP' version, what was commercial actually.
This new release with sources is improved in some things.
In any case thanx. I will check is it better playable.

Re: Problem with autoboot.

Who is that sod PPera ? :lol: Yep, that's obviously IDE adapter, because of cable and CF card. And I guess that there is option for TOS 2.06 use. 2 GALs ? I solved it all with 1. Anyway, if it runs well driver for twisted cable from floppy, and does not autoboot it, then something is not OK with TOS...

Re: HDD drivers. How does it work?

When you doing some extension - like ICD did with ACSI protocol, you do HW and SW parallel - that's the only way what ensures it work well. In my opinion, it was one of best done on ST - basically, it just adds one byte in command chain to activate extended mod. That needs not some complicated HW. T...

Re: HDD drivers. How does it work?

Why is that I must do everything myself ? :D Looking schematic says that blitter CLK is connected to 8MHz clk. So, it never works at 16 - that's case only by Falcon, which has 2x faster RAM. CPU clock comes from one of PALs - can be 8 and 16 MHz. Not to mention that there should be then bit to set b...
