Any interest in a 128T mod blog?

They have 128 Bit computers already?

Sort of. If you apply some of the old marketing ideas of "bitness" rather than the machine pointer/word size, then things like AltiVec and SSE are 128-bit, since they have 128-bit wide registers

Ahem... 128 KiloBYTES, it is superior

That is a thing of beauty, you must have really love c64/128. I went right from c64 and tandy color computers to amiga myself, but I did get a 128 later.

I've always wanted to build a custom amiga tower. Someday I will I suppose if I ever find enough parts I can afford. I have a full tower case, a 1200 motherboard and ps.
I need an accellerator, keyboard adapter and pci adapters and so on. could get expensive...

damn you Red  you caused me to get my C128 out of the loft and hook it up to my 50" tele - composite video colour bleeds horrible... I'll need to get some convertor

My plan is working... Excellent... :cool:

Use the S-Video output.  It's not perfect, but it's much better than the composite.

Actually, I'm playing with tapping the S-Video signal directly from the VIC-II.  By passing it through a voltage divider and an op-amp, I'm actually ending up with a signal much cleaner and purer than what's offered from the video port.

If anyone's interested, let me know, and I'll share what I've learned so far.

But of course I'm interested

me two :p    s-vid ? on a C128 ? just think of me as an idiot on this subject ... I am ;-)
I used my composite cable that came with my 1084 monitor ages ago (monitor gone since long)

Well, as you know, the video port already provide a S-Video signal.  However, I find this signal quite noisy (especially on my C64), so I'm trying to extract a decent signal directly from the VIC-II.

Pins 14 (Chroma) and 15 (Luma) on the VIC-II spits out an amplified S-Video signal.  By applying a voltage divider and an op-amp to "balance" the impedance (in the lack of a better word) I'm getting a much cleaner and leaner signal than what the video port provides.  I can take some pictures from the oscilloscope to prove this.

I'm sorry I'm a bit vague on the details right now, I'll see if I can look into it tonight.  I just got back from the hospital after receiving my second child, so I hope I'm excused

Congrats!!! Enjoy that baby and take care of the mother. We will be here when you get the time:D

In case you missed it, I posted some screenshots last night.

I'm happy to report it is still possible to read and post on Amiga.org from a Commodore 128. I'll try a more Commodore specific browser than Elinks soon.
