Macintosh II si - Classic Design Curves... -

Macintosh II si with Keyboard and Mouse. 5 MB RAM and 40 MB harddrive installed. Photos

The IIsi shares some features with the SE/30, the LC series, and the Mac II series. Like the SE/30, it has a 68030 PDS for expansion. Like the LC, it has no built-in NuBus slot, is quite short, and has a curved front. But with an adapter (not included in this auction), the PDS can be converted to a NuBus slot, making it a legitimate member of the Mac II family. You can buy a suitable display here.

Although the IIsi was marketed as a 20 MHz computer, users quickly discovered it used parts rated at 25 MHz. (Apple had intended it as a 25 MHz computer, but chose to scale back the speed to avoid cutting into IIci sales.) Chipping the IIsi to 25 MHz -- or even 28 MHz -- is not unusual.

Along with the LC, the IIsi was one of the first Macs with audio input. You can do a lot with a IIsi. I know of a Mac IIsi being used as a server for an ethernet network, another being used to play kids games, and there are even some where I live being used for QuarkXPress and Illustrator.

Macintosh II si - Klassische Design Kurven...

Macintosh II si mit original Keyboard QWERTZ und Apple ADB Desktop Mouse.5 MB RAM (13 virtuell) - System 7.5.3 D - Revision 2

Der mit 20 MHz getaktete auf dem Motorola MC68030 basierende Rechner mit einem maximalen Arbeitsspeicher von 65 Megabyte wurde von Apple im Oktober 1990 vorgestellt.

Apple vermarktette den si als 20 MHz Rechner um den Verkauf des IIci nicht zu gefärden - aber der Mac IIsi ist auf 25 MHz angelegt und kann daher bedenkenlos "übertacktet" werden. Es kommt hierbei nicht zu überhöhter Wärmebildung.

Zur Erweiterung steht ein PDS Slot der mittels eines Adapters (nicht in Auktion enthalten) zu einem NuBus Port konvertiert werden kann. Neben der 8-bit Farbgrafikkarte auf dem Motherboard verfügt der II si wie alle Vertreter der II Serie über ein 8-bit Stereo Soundsystem. An den SCSI Bus des Systems können extern CD-ROM Laufwerke, Scanner oder Streamer angeschlossen werden.

Einen passenden Monitor (SW oder RGB), können Sie optional auch bei mir erwerben.
