Notes:
|
1.
This model is sometimes designated as having a 50 MHz
processor,
 since
the clock input runs at 50 MHz. However, the processor
itself
is
not "clock doubled", so technically it is only a 25 MHz
processor.
2. Third-party
upgrades and accelerators are available.
3.
Some models have 4 MB and others have 8 MB soldered.
4.
RAM can be interleaved to improve performance.
5.
Both 256k SIMMs are replaced with 512k SIMMs for 1 MB
VRAM.
6.
One external 5.25" bay is available if CD-ROM is not
installed.
7.
In inches, height x width x depth.
