Tf1230

awesome to see new hardware TF style with no drama

[Akiko]

I was just thinking the other day how lucky us CD32 users have been, as for the last couple of years we have had an abundant supply of 030 accelerators in the form of the excellent TF330 which have been available pre-built, disruption free supply from several different sources. The A1200 users on the other hand have had little option other than scour eBay for used 030 cards at much higher rates, or wait for erratic supplies of new 030 cards, if any have even been built in the last year or so?



I think anyone arguing the TF1230 should include an FPU are just nitpicking IMO, as said 030 class accelerators only benefits from this feature on very rare occasions, so it makes sense that the handful of people that need this niche functionality should just track down a Blizzard IV, or ACA card and pay the premium. As for everyone else upgrading from stock/memory expansion this will be a nice upgrade, especially for those of us that insist on using higher resolution AGA Workbench modes, having the 030 is a real benefit, including demos, apps, etc.

I know only one game requiring FPU on 030: TFX (and it crawls even on 68060+FPU...)

And in 2020 running productivity on 030+FPU is just soooo 20th century...

So yes, FPU isn't really a must have, no.

Yea.. That's basically what I and some other ppl here are saying.. IF you need to run software that requires an FPU.. what you really need is to get a 040 or 060 instead..

Brilliant news All new hardware is always welcome. I only wish the Terrible Fire guy would do an 040, as one doesn't need to sell one's kidneys for an 040

[Chucky]

040 wouldbe pointless..

it would not be cheaper than 1260.. and the 040 is too damn hot anyway

[Chucky]

it boots. but no ram at the moment. and well 14MHz. but I got the pcbs today.. so I would say "progress"

@ Chucky


so sweet We amigans are just so blessed and spoiled with all this great brand new hardware being released nowadays...truly an amazing time for Amiga users

If you want to play those games properly and as they were intended to be played, you'd play them on a PC. Lightwave 3D got ported to MAC/PC. And you'll get more bang for the buck. Virtually everybody has a PC nowadays anyways, so no reason at all to fiddle around with your Amiga anymore.
Nothing makes sense in the retro community, or in a hobby for that matter. I've spent an insane amount of time and money on retro stuff that won't pay itself back economically. Do I regret it? Hell no! Is it fun? Hell yes! Is it worth it? Most definitely.
A hobby is ment as a recreation. Definition of recreation is "an essential element of human biology and psychology". So for me it fits the description. If it doesn't fit for you then it's either your job or it's not a hobby ment for you.

When it comes to wether or not it has a FPU slot; who cares? Stephen Leary is doing a great job for the community. We should thank him for that and stop acting entitled. And if this product isn't for you, then you should move along.

Great to see new hardware being developed for the Amiga. Looking forward to updates on this project!

Great to see that someone finally realizes that EOS is a thing and is actually using level shifters this time. This board might actually be worth buying.
TBD: Learn why every commercial IDE controller on the planet has resistors on the IDE signal lines.
Edit: Oh my god, I checked the A1200 schematic and Commodore didn't terminate the IDE bus on the A1200. Strange since I see it elsewhere in the schematic. I wonder if it wasn't part of the standard back then?

What is "EOS"?

[Shadowfire]

Electrical over stress

The ATA-1 specification does not say anything about termination, only that...

The physical interface consists of single ended TTL compatible receivers and drivers communicating through a 40-conductor flat ribbon non-shielded cable

Here's a typical ISA bus IDE controller card. Data lines appear to go directly to/from 74LS245 TTL bus tranceivers with no termination.

[Shadowfire]

Ah, so this is for the pre-ATA-33 spec.

Table 3 - Cable parameters
+=============================================-======-========+
| Cable length of 0,46m (18 inches) * | Min | Max |
|---------------------------------------------+------+--------|
| Driver IoL sink current for 5V operation | 12mA | |
| Driver IoL sink current for 3,3V operation | 8mA | |
| Driver IoH source current | | -400uA |
| Cable capacitive loading | | 200pF |
|-------------------------------------------------------------|
| * This distance may be exceeded in circumstances where the |
| characteristics of both ends of the cable can be controlled.|
+=============================================================+

They weren't really bothering with signal integrity on the controller cards at this revision of the spec, they just limited the cable length to 18" and spec'd out the drive strength to try to minimize reflection.

[Draft ATA-3 standard]
Even by the time they were running the bus @ 16MB/second, they were well aware of the problems with the original ATA standard (which really had no SI controls). See Annex C in the ATA-3 standard for a more detailed explanation.

https://inst.eecs.berkeley.edu/~cs15.../ATA5_Spec.pdf
[Draft ATA-5 standard]
Section 4.2.2 talks about UltraDMA termination, and has a much more detailed annex about signal integrity.

Looks fantastic! would be great if this speed of this, was controllable by software, like the TF1260

[indigolemon]

Update! https://www.exxoshost.co.uk/forum/vi...hp?f=70&t=4526

Ok so since Edu Arana has bascially restarted the TF1230 that he abandoned a few years ago I suppose i should just get this out there. I'm pretty unhappy with Edu mainly because he abandoned it and then restarted it without telling me. I wouldnt have bothered doing a 1230 card if i'd known this.

So i am prepared to add the TF1230 eagle and gerbers to the TF330 repo while i develop the firmware further. Its not far away but will need beta testers but will be entirely at risk. Who is interested?

[Estrayk]

Tsunami 1230 isnt based in TF. I dont know why Stephen Leary said that. Miguel Fides did it, the same person who made the Amiga A1100.

Btw, seems the Tsunami runs fine:

Oh, I see you didn't read the thread on Exxos...

I think I'll be building one. I have an A1200 edge connector. Never quite knew at the time why I bought it, now I do.
