Hello there, all of you 8-bit gals and guys!

I recently purchased a pair of ArmSID chips form the Retrocomp.cz shop and I was amazed about the quality and craftsmanship of the actual chips, as well as about their packaging. So I thought to share this with you here and do a small comparison of the SID chips I possess. If one of you has another SID-alternative, please feel free to add them here.

The ArmSID comes in this beautiful little box.

C64_SID_ArmSID2.jpg
It rests comfortlably on a piece of ESD foam inside.

The chip is actually a tiny PCB the size of the original SID.

C64_SID_Comparison.jpg
Here is a comparison between an original MOS 6581 SID, the ArmSID, and the FPGA SID.

C64_SID_FPGASID.jpg
The FPGA SID has a larger PCB, but it also has some nice additional features.

Speaking of the FPGA SID: You can get one and all relevant information about it here from the FPGA SID homepage (German site, English language).

That's it for now. Cheers! <3

Nice...what does the ARMSID look like on the underside?

Well, that is a valid question. ;)

The underside of the ArmSID.

And just to complete the picture, here's the underside of the FPGA SID too:

Sorry for the blur on the left-hand side.

Amazing how the ARMSid does it with so many fewer components than the FPGASid!

I can’t wait to hear the differences and similarities of these chips.

I bought a couple of these a while back and that was the first thing I noticed too. A++ on the presentation. The sound quality is also excellent and there are quite a few things you can tweak too. I don't have it in a machine at this time but I plan on doing a comparison between that and the few revision SIDs that I have as well as a NanoSwinSID, which IMHO is nowhere near as capable as these modern SID replacements. I don't have an FPGA SID as I opted for the sleeker ARMSID.

Has anyone documented the true incompatibilities for each SID solution? For example, which games and demos have bugs on certain solutions.

It has been years since I've looked for a replacement SID, but half a decade ago most of them didn't support paddles, etc.

Things like that.

I have a SwinSID Ultimate that I purchased a couple of years ago, and it has paddle support. I am pretty sure these two newer entries do as well.

As for the FPGA SID, have a look at its specifications. As far as I got with experimenting with it, I had no incompatibility issues so far. In comparison with other SID solutions, the FPGA SID is the flagship device of SIDs so far, at leat imho. Ok, I have to admit, they are quite expensive, 75,- Euros per unit.

I have 2 FPGA SIDs mounted on my Ultimate 64 board, so this machine runs in fact 4 SIDs parallel, theoretically. ;)

I do not have experimented with the ArmSIDs yet...

Personally I use the emulated 6581 and 8580 SID's built into the 1541 Ultimate II+ snooping at a range of addresses ranging from $D400 to $D780 for twin/stereo SID's and IMO they sound fantastic. Furthermore the 1541 Ultimate II+'s Ultimate Audio Module is fantastic, playing up to 80 channel MOD files on the C64 is just amazing. I think it's the most versatile solution around.

Best of all, it connects to my speakers via a simple and convenient stereo jack.
