I'll probably go for the DS0/DS1 option on the internal connector. If people will use a drive at all, it'll be somewhere internal. I highly doubt that the DB23 connector will be used by anyone (and if so, only for part-time use), and it's way too expensive "just for the sake of having it" (expensive by means of financials as well as board real estate).

Having a PS2 translator on a mainboard that uses the original keyboard-cases sounds odd to me. If I'd target some modern form factor that uses external keyboards, then yes, a PS2 keyboard would make sense. At this point, however, you'd be creating something truly Frankenstein.

If people have an RTC on the accelerator that they choose (for example a Blizzard), they will have paid for two in that case. That's the part I want to avoid. These OKI/Ricoh-compatible chips aren't exactly easy to find, and putting them on a board as standard means you make everyone pay for it - even those who don't need it (because they want a gaming machine) or who already have one. You'd be surprised about the low percentage of RTC modules sold vs. the amount of A1200 accelerators: Only few people consider an RTC worth spending money for. Sure, everyone takes one if it's free, but at the end of the day, every chip must be paid for by someone.

You still need drivers on the Amiga-side, and that's the most expensive part. I read that a lot: People consider my products expensive, because they count the $$ worth in parts on the board, and compare to the sales price. Hardly anyone sees that I have monthly bills to pay while I develop this stuff, and the same is true for my employees. So RPi as IO for the Amiga? Rather not, as it would create a 50k-EUR piece of software that talks to a 30-EUR piece of hardware. How many illegal copies do you think would exist within a blink of an eye? Any who do you think will end up paying such an expensive development?

I will most likely go for a few LEDs as early diagnostic (where "early" means before the monitor can show characters).

Here's another example of a Mr. know-it-all who considers the price of the components as the main factor for the price of a product. This may be true if you produce a 40-ft container of some PC product, but not a small-scale production run (where "small scale" is anything below 50.000 pcs in the first run). If you can make a USB host controller with all the required software for 50 EUR - why don't you just do it? I'd be more than happy to quit making RapidRoad and buy your product instead. Oh wait, you'd serve all those customers... OK, well, just come out with your product.

The ACA500 was mainly a 5V-design where only the CPLD was a 5V-tolerant 3.3V-part. The ACA500 plus is over 60% more expensive than it's predecessor (130,- Vs. 80,- EUR), and uses mostly 3.3V parts. This factors in that I'm losing those customers who want a very low-cost product: I won't be able to make an 80-EUR accelerator with the specs of the ACA500plus.

Note that the "Apollo" designs are not designed by me, but bought by me, so I could shelve the world's worst Amiga products that are responsible for too many Amigans leaving the hobby due to unstable computers. So no more discussion about Apollo, please: Use them if you want to, but don't bother me.

1. leave a space for an optional 020 to be soldered to the board, on request, or,
2. produce a very basic 020 card
The "on request" part implies that there's a space on the board (=PCB real estate that everyone would be forced to pay for) plus support circuitry that makes the CPU work. How is that any cheaper than making the cut in the most natural location: The CPU port? I'm pretty open about the cost of the materials for the lowest-cost CPU card: The ACA1221 is pretty much sold "at cost" in it's lowest config: just under 80,- EUR incl. 19% VAT. If you remove the CPU, you save maybe a dollar, and if you remove the connector, you might save another few dollars. Give or take some extra stuff around it, you still need to calculate 70,- EUR for a CPU+RAM system that comes without CPU. This would be sitting there idle - totally useless to a good part of the customers who choose another CPU. I just hate wasting resources like that.

The audio discussion was a little lengthy, but definitely worth looking into. Thanks for that.
