During the 1980s, many vendors sold small, pocket-sized computers that ran BASIC.Despite their small size and low power consumption, they were relatively capable and could interface with tape storage and thermal printers.The SHARP PC-1500 was a very popular model with a Z80-based CPU.
However, its weak point was the small amount of RAM and storage space for programs – only 2k.Some expansion modules are still found for sale from the period, but they are ridiculously expensive.This 16k RAM Module with Battery Backup is a great way to breathe some new life into these old machines! Not only does this give a huge upgrade to storage space as NVRAM, but it also uses modern memory chips which are very low-power.
This means the CR1616 battery should be able to keep the contents of RAM for a long time.This is useful as the machine uses 4xAA batteries.Ideally, using rechargeable AA batteries should be the goal, but you still need to power down the device to swap batteries; this would lead to the memory being wiped without a secondary power source.
Gold-plated contacts ensure a good connection to the expansion port connector.This module is compatible with all SHARP PC-1500 and PC-1500/A models, as well as the TRS-80 PC-2 model rebadged for sale at Radio Shack.Pick one up and supercharge your classic pocket PC while still enjoying the vintage BASIC programming goodness!
