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.
