Tired of looking at your scratched up / damaged Atari Portfolio clear inner see thru plastic display window / cover (over the Portfolio LCD display)? This is one of those once in lifetime chance to get a Brand New replacement Atari Portfolio OEM Clear / Gray display Mylar Cover / Window for your 39 year old Atari Portfolio. Each new replacement Portfolio plastic see thru display cover comes with an adhesive backing (peal off the back temporary cover to expose the adhesive) and a temporary clear protective plastic over the front cover. Some Portfolio owners leave this front clear protective plastic sheet on, to protect the new Portfolio Window longer, some remove it to get a clearer Portfolio LCD display. CB102207 $19.95

Best's 40+ Year Atari Super Tech's Atari Portfolio tech tip on how to easily remove the old Portfolio Window without damaging the Portfolio inside gray plastic bezel. Heat up the old Atari Portfolio inner see thru display cover with a hair dryer (usually a medium heat setting), until it becomes very warm to hot to the touch (but not enough to start to distort the old cover / window / inside Portfolio plastic bezel), the from one of the four corners, start peal off old damaged / scratched Portfolio display window and just peal off the old window left to right or right to left.

Something most Portfolio owners do not know. When you remove the old Portfolio Window, you will see two small black case screws (in two recessed case holes in the inner plastic bezel) that hold the top / outside Portfolio plastic case to the inside plastic bezel / case. On most Portfolios you will see a third slotted silver screw head thru a small hole on the left of the inside Portfolio bezel near the speaker. On some early generation Atari Portfolio inner display gray plastic bezels, there is no adjustment hole over the Contrast adjustment screw on the LCD PCB board. This shinny metal slotted screw head is the Portfolio LCD Contrast Adjustment screw. Using a small slotted screwdriver, you adjust the contrast LCD display setting to a darker or lighter LCD display / letters. The more you adjust this screw, the letters on the Portfolio LCD will get darker blue color, but also the LCD back ground will go from a clear background display to a darker blue color. It is strongly advised, you make a one time display contrast setting change on your Portfolio. Because once you apply the New replacement Portfolio window, trying to repeal off the new Portfolio window a second time usually puts a memory in the bent up corner side of the new display window which will always never seem to sit flat the second time you try to flatten it down.

Portfolio 220 Volt German Power Supply Two round pin plug version 220 volt side. CB102732 $12.95

Portfolio Plug in 256K Memory Expander with pass through Portfolio buss connector. The Atari Portfolio Plug in 256K Memory Expander will Triple the memory on your Portfolio and adds a second Memory or Program Card Slot (Drive B:) at the same time. Features: Increases the Portfolio’s Memory from 128K to 384K and increases the Maximum size of the RAM disk (C:) from 80K to 336K, Adds Enough extra memory for up to 132 pages of Text, Pass through Bus connector still allows you to connect Atari Parallel or Serial Interface peripherals, Second Memory Card Drive (B:) allows you to copy files from One Memory Card to another Memory Card-thus allowing you a safe way to replace aging batteries in your Memory Cards before they lose any valuable Data!, Pass through bus connector allows you to Connect a second Atari 256K Memory Expander to increase your Portfolio’s total Memory to 640K and allows a 592K Memory RAM Disk. Installing or removing a Portfolio 256K Memory Expander into or out of your Portfolio requires a Complete Cold Boot of the Portfolio. So always back up all Data Portfolio’s Memory information before installing or removing the 256K Memory Expander. Since the 256KMemory Expander re-quires no external power and gets its power to maintain the memory from the Portfolio itself, this Expander should Never be removed from the Portfolio or installed into the Portfolio with data in the Portfolio Memory or Expander Memory, in both cases it will require a Cold Boot (Erases the contents of the Portfolio’s Memory-both RAM and Drive C) of the Portfolio before it will work again. In other words once the 256K memory Expander is installed and the Portfolio is configured to recognize the extra memory it is best to leave it installed or do a Complete Cold reboot of your Portfolio every time you install the 256K Memory Expander.

Atari Portfolio Ram Card Tech Tip: Remember that all Atari made Portfolio Ram Cards (32K, 64K and 128K) have an internal very thin lithium CR2016 coin battery (they can be accessed / removed on one end of Portfolio Ram Card that hangs outside of the Portfolio case, the internal small crescent shaped black plastic coin battery holder, sometimes have a very very small sliding locking tab on the end of the Portfolio ram card edge to lock the battery holder into the ram card) to keep voltage on the Portfolio Ram chips when the card is not inserted into the Atari Portfolio PDA. These lithium coin batteries are have a fixed life cycle (typical 1 to 3+ years of use / Portfolio Ram storage time, depending if the Portfolio ram card is left in a running / power up Portfolio all of them time or stored outside of the Portfolio) when used in an Atari Portfolio Ram Card. Never replace the old Coin battery inside the Portfolio Ram Card when the Portfolio Ram card is NOT inserted into a power up Portfolio PDA or other powered up device that uses these Portfolio Ram cards. There is a very good chance you will loose all of the stored Portfolio data on that Portfolio ram card if you don't. Only replace the old dying Portfolio Ram Card battery when you have it fully inserted into a running / power up Portfolio or other device that uses these battery backed up ram cards and make sure you can access any Portfolio data stored on that Ram card 1st. This way the running Portfolio or other power up device will supply voltage to the inserted Portfolio Ram card, to keep the Portfolio ram chips voltage up, while you changing out the old dying 2016 battery.
Also another good Atari Portfolio Tech Tip: A good idea after inserting in a new fresh Portfolio CR2016 lithium coin battery into a Portfolio Ram Card (using the replacement new battery technique above) is to double check the exact voltage (with a VOM meter) left on the CR2016 Coin battery about 6 months to a year later after you have changed out Portfolio Ram card batteries. This will give you a rough idea when you should do the next Portfolio Ram Card new battery swap out. You should not let your Portfolio Ram Card batteries drop below 2.50 volts, below this amount of volts you will start to loose memory storage / data on your stored Atari Portfolio Ram cards. Use the small Portfolio labels that are provided with each new Atari Portfolio Ram Card to mark the date you installed a new CR2016 Colin battery and the next date when a new fresh CR2016 Coin battery should be installed in your Portfolio Ram Card and apply this small label to the Portfolio Ram Card.
