My A500 "project" pics, details, build log?

Lol, get a 1541u2, they do pretty good dual Sid emulation and transform your c64 into a real beast (REU up to 16mb, all save carts, jiffy dos rom support, tap support, g64 support etc)

[djos]

Btw, I found a Seller on fleabay with a nice pack of replacement BreadBin c64 Caps and Voltage regulators for $10aud delivered so I grabbed a set.

I put the good chip in the bad motherboard... sounds good...
so, I have two bad SIDs...

That sucks, you can usually pickup replacements on ebay tho.

[djos]

Btw, ive been given the below contact in France who supplies a500 Capacitor replacement kits.

I've send him an email requesting 2 kits for my a500's.

Early SID chips need 9vac to work properly on the C64 Breadbin model. Check your voltages and amperes.

[AmmoJammo]

they are all early SID chips, and I've been using the same power supply for all testing.

I have four chips total, two seems to work, two are crackly..

On another, related note, I made an XA1541 cable today, using 2N7000 mosfets from Jaycar, 60 cents each, needed four, plus a 25 pin male DB connector, already had a backshell, and I cut a spare floppy cable in half.

Well, it refused to work in Windows 7, so I pulled out an old Windows XP machine again







SO! any good games I should get? or even music demos? something to test the SID chips fully?

[djos]

Here's SIDBench

as for games, check usenet for the Blast Collection (almost 2,000 games in that collection).

[AmmoJammo]

Are there any demos like on the Amiga?

[djos]

Thousands!!

Thanks, at least theres a sound file on there so i know what Im listening for

[djos]

Yeah it does help to know what you are listening too.

I found the CBM6581 sounds most like mine (aside from the slight pitch difference) and I use a set of monitor headphones to do the comparison as they remove a lot of external noise.

Dont forget the 4700uF, 16volt capacitor, and 5volt regulator in the power supply itself.

Unless you have a power supply that you can't open...

How hard is it to take the PSU apart and replace those parts?
