Re: DEMOS.

Does that mean my GEMDOS partitions are breaking some demos? Well no, I lost half the explanation there. For ACSI hardware, this isn't relevant. However, for IDE interfaces, if you're partitioning in a TOS/DOS compatible format (i.e, you can put the card in a PC/Mac and it reads the content correct...

Re: DEMOS.

Some newer demos require not only being run from HD, but also a specific lowest speed as well. As long as your driver isn't doing TOS/DOS partition compatibility byte swapping in software, any ACSI emulating driver and harddrive will probably work. What doesn't work is the Unicorn USB host adapter (...

@troed - currently these are ABS but have been playing with different material on the printer.
That's really impressive - I would expect extremely problematic warping at those sizes with ABS!

Re: Curt Vendel...

A lost life is always tragic. It's doubly so here considering how much Curt was curating lost Atari treasures.

I will miss his FB posts (the only way I had any contact with him).

Indeed when we get nearer to a complete case will look at giving these a bath :)
You're printing these with ABS?

Re: Troed's H4 build

CPU_DTACK.D = SYS_DTACK # CPU_AS; CPU_DTACK.OE = !SYS_DTACK; Thanks, I have no idea why this turned out to be so problematic. 'stock' below is 1 when running stock clocks: *** INPUT *** PIN 10 = !DTACK; *** OUTPUT *** PIN 14 = !DTACK_OUT; *** equations *** DTACK_OUT.D = DTACK & stock; DTACK_OUT.OE ...

Re: Troed's H4 build

I've had some progress here. The GAL is up and running the H4 fine with "stock clocks" being emulated, just handing out 32->4MHz via the jumpers. But it turns out my lack of proper micro electronics education is catching up with me - I don't seem to be able to figure out how to handle DTACK. In stoc...

Re: WTB: Falcon DSP IC

Wonder why they used a odd package of it :roll: Actually I think it's Motorola that offered weird packages :) Low pin count (88) was PGA thru hole. If you wanted SMT the package they offered was a 132 pin CQFP or PQFP. So it might simply be board space or pin spacing that was behind Atari's request...
