A MacEffects exclusive, a 8mb memory card for the Macintosh Portable series. The design was originally engineered by Techknight in 2014. Design updated in 2020, our 8mb upgrade card for the Macintosh portable uses the memory slot rather than the PDS. This card features red activity LEDs for each bank of memory. Genuine Toshiba memory chips made in Japan. These memory chips are no longer made so quantity is limited.
Our memory card will come with jumpers pre-configured for your system to allow a maximum of 8mb of recognizable memory for the machine. Some users have reported sucess adjusting the jumpers to allow 9mb of memory, however, some users reported crashes in this configuration. As such, 9mb is experimental and not supported by MacEffects (use at your own risk).
Our memory card will come with jumpers pre-configured for your system to allow a maximum of 5mb of recognizable memory for the machine. To utilize more memory than 5mb you would be required to attach a jumper wire (included) from the "/AS" pin on the memory card to the "/AS" slot on the ROM slot. Because of the risk of installer error, we can not provide assurance or assistance with this process. ROM slot diagram will be included for informational purposes. For M5126 users, this card is being sold as a 5mb card.
