This is a
midi-controlled TIA audio IC from an Atari 2600 and various classic arcades of
the late 70’s and early 80’s. It’s housed in a road-worthy extruded aluminum enclosure; you could probably jump up and down on this device and it would continue working just fine (but please don’t do that). This sale is for unit 8, made in a short run. Units 5, 6, and 7 sold on another venue, 1 for $125 and 2 bulk-discounted to $85. The TIA IC installed in this unit is new-old stock, meaning that it wasn’t
pulled from a used game system; it was warehoused and the first time it made
sound was when I tested it here. The
video linked on this page contains a short audio demo. This instrument can do allot more, but the
demo should whet your appetite. The oneUP!
midi synth connects to your usb-capable midi controller or DAW by a common mini
USB to USB A cable. The audio out is by
eighth inch jack.
When connected to
my Windows PC, my DAW recognizes oneUP! immediately. The device is small enough to fit in the palm
of your hand or your pocket. The work in this short run was very much ‘by hand’, aside from the PCB which I designed and had manufactured at a board house. This unit features a newer PCB revision and tighter design than the first. The build is solid and durable. The audio output is nice, loud and

The design is based off of Brian
Peter’s TIA chip synth under the MIT license.
Besides the provided demo, it’s capable of everything in Brian’s demo,
too. This unit includes a CO10444D
“Atari TIA” audio IC. This unit features a socketed Atari TIA IC, that can be removed and replaced if needed. After the first twenty units, I will most
likely be out of TIAs. The largest reliable source says they’ll only sell ten of these to any given customer: not in one purchase, but total. These ICs are sporadically available on eBay, though the condition is much less trustworthy. I currently have a few new-old stock TIA ICs on hand from a good source.
*Some later units in this group feature an updated label with the “Chocolatchips” logo added. Besides that superficial difference, they’re identical to the previous units and the pictured unit. Returns are
usually fine with me, providing there’s no damage or evidence of dissecting the
item. I can also service this device for
you in the future, if you stay in touch.
Shipping will be insured, of course, and tracking will be provided. This item will ship within 24 hours of your
purchase. I do everything I can to get
orders in the mail the same day as they’re purchased. Thanks for looking!
