TF1230 Beta Interest (Open Source)

[terriblefire]

I poked software reset a little bit more, and it is consistent on my Amiga.
It affects both kickstarts, and non of software reset applications work with my TF1230.
I disconnected TF1230, and it did work again on vanilla amiga.
So far it looks like only I am affected by this issue?

Perhaps try some different values of R1. Its on the bottom of the board north of the CPU. It should be 1K.

Ok i'm pretty happy. Here is my RC1.

I've fixed everything i can reproduce. 030 enable now works. Speed is maxed out without taking liberties with timing.

Enjoy people.

It was something doggy with my test image (I reused my old test A500 image). I suspect cpu fastrom command.
Now it works great!

Anyway sorry for false feedback.

RC1 - enable works great I am about to run some speed tests on cpu and ide

In the time honoured tradition here is a sysuselessinfo result pic LoL, it is comparable with the TF330.

I know you hate praise Steve but your work in the last few years has been prolific and phenomenal and the Amiga community has benfited hugely by bringing affordability to a scalpers paradise, cheers mate !

Well... unless there are any more bugs my 030 days are over.

What about Amiga 600?

[terriblefire]

There is no reliable way to do an A600 accelerator. So i will not do it.

Plus the Furia exists as a low cost accelerator for the A600. It's not really something that needs to be addressed.

[Danoo]

For those that are interested here is a more exact costing, I usually do a quick cost analysis before any project, I had the wrong CPLD in there originally, but I have amended it to the cheaper XC95144..

Some of these parts I already had from previous projects and their costs may have gone up or down a little since they were purchased.
I usually always order smaller parts in quantities of 10 or above for cost effectiveness.
Also you will notice the GST (Australian sales Tax) figure at the bottom, so costs will be different depending on your regions sales tax requirements (approx. + or - 10% I guess)

Costs (AUD)

The PCBs I had manufactured by JLCPCB (Min amount 5 PCBs, will probably sell or give away the ones I don't use) they work out at just under $14 ea delivered(without passives attached) I don't mind soldering

So if you build it yourself, a A1200 50Mhz 030 accelerator with 64MB of Ram (128MB will cost a little more) without CPU, for $95 Aud (50GBP).
As I wrote earlier thank you very much terriblefire what a bargin

Btw.
What was the cause that this card initially worked only on some board revisions or was it only related to ROM?
