Welcome to my computer museum! Come step back in time with me and visit the exciting, diverse days of computing past!
Detailed information, photographs and other snippets of data for each system will be filled in slowly over time. Watch this space for updates!
APPLE COMPUTER

Macintosh 512k

Featuring the somewhat uncommon DoveSnap upgrade board set. This included a small riser PCB fitted with the 128K Mac Plus ROMs to replace the original 64K Mac 512K ROMs and an expansion memory board to take the system up to 1 Meg of RAM. At least one of the DRAMs on my memory expansion board seems to have gone, but the system will POST and run as basically a 512Ke.

Macintosh Plus

Macintosh SE

This FDHD model with 20 Meg internal hard disk drive provides all the classic Mac experience with all the modern conveniences. The ability of the Mac SE to use ADB peripherals means never being caught short for a keyboard or mouse. This machine runs System 7 and with MacTCP and a Cayman Gatorbox, it can connect to the Internet via LocalTalk.

Macintosh IIvx

Macintosh IIfx

The first computer from Apple at the $10,000 price point since the introduction of the Lisa! The hardware design of the Mac IIfx included several sophisticated features not seen in other Macs, the capabilities of which sometimes were only tapped in A/UX.

Macintosh Quadra 800

Macintosh Quadra 950 (as Apple WGS 95)

Running A/UX 3.0.1

Power Macintosh 6100/60 DOS Compatible

Power Macintosh 8500/200

With sophisticated onboard A/V capabilities, this machine was almost as cool as the BeBox when it was released. Steve Wozniak and Larry Tesler were quoted as saying the system was their favorite Mac of the time. The easily replaceable CPU and a sizeable number of DIMM sockets provided the Power Mac 8500 a long usable life.

PowerBook 180c

The first PowerBook (and possibly the first laptop sold commercially in volume) with an active matrix color LCD screen. Also connected to the Internet via LocalTalk using a Cayman Gatorbox.

Newton MessagePad 130

The Newton line was visionary when released, the first PDA sold to provide natural handwriting recognition.
