RAM Disk
Battery-backed SRAM powered by the wall power when present, the AA batteries when wall power is absent, and the CR2430 coin cell when wall power and AA batteries are absent.
Internal ram upgrade socket can take a single chip, either 32K or 128K.
- 32K: 32Kx8 parallel SRAM, 5v, low power, DIP-28
- 128K: 128Kx8 parallel SRAM, 5v, low power, DIP-32
Many different chips are compatible. Here are just a few for example & reference:
- Hitachi HM628128LP
- Alliance AS6C1008-55PCN from DigiKey or from Mouser <-- BEST BATTERY LIFE
- ICSI IS62C1024LL-70W also LL or L, 70 or 55
- BSI BS62LV1024PC-70 also 1025 or 1027 or 1028, PC or PI, 70 or 55
- Toshiba TC551001CP-70L
- AMIC LP621024D-70LL
- Goldstar GM76C8128
- Samsung KM681000BLP-7L
- ASI MT5C1008CW-70L/883C
Generic ebay search for the type of chip, not a particular part number:
https://ebay.com/sch/i.html?_nkw=128Kx8+sram+dip+32
Installation:
- Turn the PROTECT switch OFF. (This disconnects the memory battery, so you will lose all documents in memory.)
- Install the chip.
- Turn the PROTECT switch ON & turn the main power on.
- Press the Reset pin or F2+CTRL+BKSP
- Format the new ramdisk: FILES -> RAM DISK -> HELP -> Format
The reset will have wiped your system settings, so you may need to configure the battery type again:
- SETUP -> System -> Battery type
If you have NiMH rechargable batteries, say NiCD
If you have rechargable lithium batteries that output a full 1.5v, say Alkaline

Serial Cable for TPDD
To connect a real TPDD to the WP-2, you need a DE9F to DB25F straight through (not null-modem) cable or combination of cables and adapters.
To avoid putting strain on the serial plug, It's better to use a cable with just a DB9M on one end, rather than, say, a 9-25 adapter plugged right into the WP-2. A cable that has DE9F on one end, and DB25F on the other end, and straight-through wiring (not null-modem) all in one piece is uncommon. It will be simpler to get a standard 9-25pin "modem" cable, and a 25pin female-female gender-changer.
Another option is you can build a custom TPDD cable just for connecting a TPDD to a WP-2 or PC
Serial Cable to PC
To use a TPDD emulator, you need a 9-pin female null-modem serial cable.
To connect a WP-2 to a PC with a real com port, you can use a DE9F to DE9F null-modem cable:
- https://www.electronics123.com/shop/serf2f6-cable-serial-null-modem-6-de9f-to-de9f-5239
- https://amazon.com/dp/B00QM8ZP5E
- https://amazon.com/dp/B00006B8BJ
To connect to a standard usb-serial adapter with DE9M connector, assuming the usb-serial adapter has a few feet of usb cable, you can use a DE9F-DE9F mini null-modem adapter instead of a serial cable.
To connect directly to a PC usb port in a single dedicated-purpose cable with no adapters:
