B-Roll: DSTB1 Atari ST accelerator update (July 24)

After a number of reports of RAM problems with DSTB1, I'm completely reworking the firmware (and applying a few bodge wires to the design).
This is has been a slow process, but I think I'm close to the end. One of the stick-outs is Day of the Tentacle, however. It's demanding on the hard disc which could be the crucial clue to what's amiss.
This is a lightly edited B-Roll video. Intended to be short, single take, non-sponsored output to show some behind the scenes working.

oooh! but I'm still waiting for the TurboPower line. Seriously though, awesome work!

Good work as usual 👍🏻

Little of it shown in this video, but many thanks! :D

Great progress!!! I might have to swap out my basic 16Mhz CPU mod for this when its available!

Cheers! I've since solved this problem (RTFM fail on my part!) but got cocky and decided I'd try to support blitter access to the external RAM. Rabbit hole!

Have you played Atari today ;) :P

I have an old creative microsystems 16MHz board from 1989 for my STFM, it has space for a blitter and FPU. Right now I'm trying to get the pistorm working without success. Unfortunately during testing I broke a pin off the old accelerator I'll have to fix. I would like to find an alt ram add on. I have seen something called a storm (thunder and lightning also) , but it's in German and I can't find much on it.

It's tricky to combine an accelerator and a RAM boad if they're not designed to co-operate. If you place the RAM board 'beneath' the accelerator then you'll only access it at 8MHz. If you place it 'above' the accelerator, you have to make sure the two don't fight. If you really want to keep the blitter socket by using your old board then you'd probably want to look for an expansion that uses SRAM so there is little complexity for them to fight. If you can live without the blitter (I'm disregarding the FPU as 68k+FPU is virtually unsupported by software) then I should have a rev 2 version of DSTB1 on PCBWay in a month or so.
