#ARMSID
Yeah pros/cons both ways. I like real SIDs because each one is kinda unique. In a stereo pair that means you can get chorusey kinda sounds which is really neat (when you want it). ArmSID is effective, but clean and precise.

For live shows, ArmSID all the way (to avoid ruining my real ones).

i'm struggling to decide If having such a SID synth full of "clones" (ArmSid, Swancantremember) is it worth for me

A post covering the ARMSID, a replacement chip in the Commodore 64. Michele Tiberi Kaio created a musical instrument. Amazing!

I wonder if there's a left-handed version.

ArmSID has improved a lot since I tested the first few firmware version, it's a good replacement choice.

If they work then that's gold!
I have a bunch of real (working) ones too. Plus a scala of hardware replacements like fpgasid, skpico and pdsid. Still want an armsid.

Most of my projects never get put in to cases so they are.. kind of finished 😊
On the left.. My Z180 RC2014 compatible computer with some add on boards I designed. Center... A SID and MIDI interface for my Z180 setup. Right... A 24MHz Z80 based system I built.

the ARMSID (replacement sound chip) i ordered worked a treat; the slot for it was already socketed so no soldering for me.

my commodore 64C has a new lease on life. thank you again avery for the requisition.

One of my C's failed and it now has an armsid in it. Great so far.

Armsid sounds great, sidkick pico is mostly good but affordable, and kung fu sid is amazing but requires getting pcbs/components and building them out. crossing my fingers for the fpga implementation being good enough for dipping my toes into tracking

ARMSid is the best (readily available) “real” SID replacement at the moment imo – would recommend over pretty much any of the other options out there.
July 29, 2025 at 10:00 PM
The ARMSID achieves that goal, imo

No. there's UltiSID emulation on board (which is pretty good!) or you can drop in up to 2 SID chips in the handy ZIF sockets if you wish. In terms of modern SID replacement ARMSID is probably best you can get right now.

In my defence, they are specific use cases. For my U64, I want a real SID because I don't think UltiSID is very good (sorry Gideon!), and putting ARMSID or SKP in a U64 seems bonkers.

For my real machine here, I want dual SIDs without spending lots of money.

From the latest release notes, it seems there are still a few things missing. I'm sure it will be up there with ARMSID in time.

SIDKick seems top end though, it's ReSID on a [very cheap] chip with a hardware DAC. ARMSID seems to manage it in software just fine though.

Final words, for now... I love this little device. To build a replacement SID using off-the-shelf parts and not even need the Pico anymore, feels like a huge win.

Best of all, they sound AMAZING. Better than some of my real 6581s. Better than ARMSID? I think so, YMMV 😉

You can use an Arduino UNO board connected to the ARMSID on a breadboard. (Schematic on the Github repository below). Using the Ardunio IDE with the ArduinoUpdate.ino sketch program the Arduino UNO configurator firmware and use a terminal on a PC to access the settings.

For reference, it works without it's NOPs on a speccy btw. Cpu is x3 compared to a 64, but the instruction length is about x3 too. Or it could be the armsid is a bit less fussy.

I would have to check the ARMSID sourcecode to see what its used for. I might do that sometime.

I guess, the clock is required for the ARMSID, at least for accessing the registers. Or for finding the correct pitch.
April 2, 2025 at 7:53 PM
I connected the Arduino ground and 1MHz clock to my own board and booooom! It immediately started playing music 😀
Sorry I hope I didnt embarrass anyone, but yes you do need the clock signal on pin 6 with the ARMSID.
April 2, 2025 at 7:52 PM
I think I have found the problem.... put the ARMSID back in the Arduino SID player on the breadboard and while listening to music playing I disconnected the clock line. It went silent. When I reconnected it the SID carried on playing music. So I will have to add an additional clock signal to pin 6.

I think, the ARMSID might check the else not required Vdd. It is connected via a resistor divider to a pin of the CPU. The audio input and potx/y can be open at the interface and their DC voltage is decoupled with capacitors from GND. Maybe, you could experimentally connect 12 or 9V to vDD.
