Even by the file and program sizes of the 1980s it's small. It's not a serious contender as a mass storage device. Unfortunately the PC-8406A 32k pack is on the smaller side of useful, and probably best as a temporary storage device for moving files around. Once the additional storage is available the PC-8401s base memory may be configured to use the full base 64k as application memory or you may keep existing 32k shared memory split. Rather than adding directly to available application memory, the expansions are used as RAM Disks and must be formatted by the Operating System before use.
These RAM cartridges were to be available in 3 sizes, 128k, 64k and 32k. Conversely the remaining 32k of RAM dedicated to file storage as a RAM disk places similar constraints on user file and program retention.įortunately memory limitations could be alleviated with the addition of RAM expansion cards. While 32k is plenty for running the software available in ROM, this limits options when running other software that may require large amounts of memory. By default the computers base 64k is divided in half between file storage and system memory.
One of the shortcomings of the NEC PC-8401 is the lack of RAM.
