Product Description

We know you take pride in the magic you make in the VIC-20's 3.5kB of RAM.  In public, you scoff at those pesky Commodore 64s with their RAM Expansion Units and the gratuitous way they waste all those kilobytes of RAM.  Still, we feel deep down you have a bit of RAM envy.  Don't worry, we won't tell.  We also suspect you've considered plunking down some hard earned discrtionary cash for one of those "Super" or "Mega" cartridges for the VIC, but you've continued to hesitate because the list of games does include your favorite, or they don't organize them in the way you'd prefer. If so, we'd ask that you consider the RETRO Innovations UltiMem Expansion Cartridge.  It serves up memory, and it serves it up your way:

  • 8 (eight) megabytes of VIC-20 programmable FLASH ROM storage.  Yes, now you control what is on the cartridge, and where it is located!
  • 1 (one) megabyte of yummy RAM storage.  Take that, wimpy Commodore RAM Expansion Units!
  • A myriad of configuration options, to suit your tastes
    • You want ROM at $2000 and RAM at $8000.  Done
    • You desire RAM expansion to be read only after you store your favorite data. We're happy to help!
    • You're insane and want the same chunk of RAM or ROM to show up in multiple locations in the VIC-20 memory map. Not a problem!
    • You must have RAM or ROM at IO2 or IO3.  C'mon, give us something hard!

 We doubt we can make you love your Commodore VIC-20 more, but we will give you some new ways to enjoy it.  Grab an UltiMem today!  And, if someone accuses you of "RAM envy", just note that you bought this unit for the FLASH ROM capabilities.  Your secret will be safe.

Note: Unit is sold without an enclosure.  We're working on a source for enclosures, but until then, snag a shell from an old RADAR RAT RACE or SPEED MATH.

  1. Can we get this for the c64/c128? 3 Star Review

    Posted by on 20th Dec 2019

    Would sure love to get this (or another 1750 XL clone) with up to 2 MB of memory storage!

  2. Best VIC-20 memory cartridge ever 5 Star Review

    Works fine. Banking is very flexible. Wish I had this 40 years ago ... would it buy again

  3. Best Option for Vic20 RAM Expansion! 5 Star Review

    Posted by on 18th May 2019

    Vic20 RAM expansion options can be frustrating. The Commodore 8k cart is actually better than the 16k cart because it comes with dip switches to allow the use of block 5 but limits which programs you can load due to size. The Penutlimate+ cart is nice but limits you to 35k. The Ultimem cart gives you up to 1mb of RAM and 8mb of ROM. I installed the Ultimem RAM Expansion Chooser (found on SleepingElephant) which let's me easily choose between 3, 32, 35 and 37k (which is needed for Doom) and have been able to load all of my software including cart images. And get this, it's $25 cheaper than the Penutlimate+ cart! I wish I had purchased this first before buying the 8k and 16k carts as the Ultimem cart has met all of my needs.

  4. Works out of the box 4 Star Review

    Maybe some instructions are missing:
    - "This side up!" on the PCB
    - Meaning of the switches
    - Meaning of the LED
