Title: Commodore 128 tower project thread #3
Post by: redrumloa on April 13, 2008, 04:03:40 AM
The last thread started off oddly and had no real flow :-) A major milestone has been made, stage one is complete! I now have a completely functional, base Commodore 128 Tower with single 1571 disk drive! Now both 40 column and 80 column are viewable on a standard VGA monitor and I may switch between them on the fly with the black toggle switch to the upper right corner of the tower.

Some other details have been completed, like I also added an original 40 col video port to the back panel just in case I want to use an old monitor, or standard video out for recording (Youtube etc). Stage 2 is under way, I am currently working on the expansion port extension cable. Boy is that a ball buster  :angry:

Congratulations it looks great!  I would love to see a shot of the inside and the rear also if you have them.

Thanks Jeff :-) These 2 pics are not completely current but close enough for now. Inside pic (http://i27.tinypic.com/14vqm9e.jpg) and back panel pic (http://i30.tinypic.com/13zqve8.jpg). You can also check the last thread (http://www.amiga.org/forums/showthread.php?t=35343) for more pics if you wish :-)

It does look fantastic, and a 128 tower is just super cool. Nice job! :pint: (It's given me the urge to set my 'ol 128 up and play a few rounds of yie ar kung-fu, LOL.)

So, how many of these are you going to build and when are you putting them on eBay?   ;-)   :-D

Awesome, your project is inspiring me to take on another similar mod for an Atari unit I have :idea:.  Your work is very clean and organized.  Thanks for sharing.....

How about playing the 128 version of The Last V8 and telling me what the trick to the first level is :-?

Haha, yeah right :-P The amount of labor and expensive parts involved makes this a one off project. This is my baby, if I ever sold it there would be a lot of 0s and ,s in the number :-D

Here's a couple pics while under construction, before completion of stage one.
 
(http://i27.tinypic.com/fbgbaf.jpg)

I have 2 converters installed. The one shown here is a composite video to VGA adapter.

(http://i28.tinypic.com/264jm34.jpg)

In the right side of this image you see the other side which is the CGA to VGA adapter, which is modified for the 128's RGBi and displays all 16 unique colors.

The output of the composite converter goes into the pass through of the CGA converter.

Ingenius! I would not have thought of the modded cga adaptor for the 16 colour mode!

I had the C=64 version. I didn't know there was a C=128 version, but if it's the game I remember, then I spent hours and hours doing that game and only ever passed the first level after a long time practicing. The trick is to just go fast and not crash at all. :-) If it's the same game I'm thinking of, where you race around the streets in the first level trying to get to the door to the underground in time, then the second level is underground and I think was pretty much the same thing with driving around really fast and I never ever got past the second level. Probably due to having to pass the first level again each time I failed the second one. :-/

Yes there actually is a 128 version that runs in 128 mode! The 128 version has more digitized speech and an additional level. The 128 version first level is not in the 64 version at all.

It's pretty easy, Mangelore over at commodore128.org revealed the easy mod that involved adding 3 resistors and diodes. I'd give a link but the forums over there seem to be down.

For a C64 tower you don't need a CGA to VGA adapter, but a composite to VGA adapter which is far more common. The CGA to VGA adapter is for the C128 80 column video display, which the C64 does not have.

I used one of THESE (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=290216128382&ssPageName=STRK:MEWN:IT&ih=019) for 40 column video. The video quality is acceptable, but you can probably find a better one for a slightly higher price.

Be warned that the power receptacle on the converter I bought was flaky. I had to open it up and bypass this port completely. That wasn't a big deal for me since I wired it directly to the ATX +12V, but it may be for someone else who isn't comfortable with soldering.

Thanks - I know the C64 is composite - though I plan to use its svideo like output instead. I was just interested in the cga mod for interests sake ... dont know if any other hardware shares  the c128's 80 column mode spec? I have an old svideo/composite to vga box in the cupboard .. it stopped working a while back, I'm hoping it was just the power supply.  It may be easier for me to get a replacement powerpack for it, than to modify the 5V or 12V from an ATX PSY to the 7.5V it requires.

I forget where I read it, possibly commodore128.org, but there is someone who made a modification to get color composite video from the Commodore 128 RBGi port. You could potgentially use an LCD with SVIDEO in with your C128 80 column.

Expansion port extension cable is complete.

If I never have to do that again, it will still be too soon  :angry: Tomorrow I start fabricating the mounting brackets for the SuperCPU 128 and RamLink.

Yeah, no kidding! I started Sunday afternoon and only finished last night, I spent many, many hours at this thing :hammer:

Cuts that bled - 1
Burned by soldering iron - 2

My brother sent me some packages from the UK.  I just unpacked one and found this inside:

http://www.retrogames.co.uk/stock/assets/images/Mach_-_Currah_Speech_64_JC.jpg

There's no manual or anything (apparently he found it at a jumble sale).  DOes anyone know much about the Currah Speech 64?  Most of what I've found online refers to the ZX Spectrum version.

I almost blew up my 1750 on the first test as my power adapter was +12VDC instead of +5VDC :oops: The mistake is fixed and this extension cable has passed tests with multiple expansions, including the SuperCPU 128.

Thanks, I am quite fond of it so far  :-D

As for energy? I have been working on it for 6+ weeks now, I am spreading it out over time and taking my time. It certainly has been a ton of labor, but when I start getting frustrated I walk away for a while. If it takes me another 2 months to finish, so be it.

You could do this, I am hoping others will get the bug to start actively using their own machines or starting projects. IMHO my project is quite ambitious, you don't have to go that extreme. Or of course you could try to one-up me and make an even better project  ;-)

As this seems to be the most active C128 thread (and because Redrumloa actually sells these things), I've noticed that a lot of people on other forums are having trouble getting their MMC64Replay cartridges to run *.T64 tape images using the v0.07 T64PLGIN plugin (it freezes when attempting run run an image).  I managed to track down an earlier one v0.04 (BIN only) and it works fine!

Also, I had hell mounting D64 images as virtual drives when setting the defaults 12/13 and a real 1571 FDD attached as device 8.  Once I hardware changed the 1571 to device 10 then the problem went away and virtual disks mounted fine.

I am truly amazed. My hat's off to you. After looking this over, I may try to get my 21" Samsung SVGA to work with my C-128.
GEOS should fly on this machine! With a good laser printer, this setup will give you great printed output!
Now, what hard drive setup are you going to use?
