5.-6. Computergeneration

Memotech MTX500

I love the case on this computer - all aluminum, and it looks great. The computer itself used a Z80A and was a solid design, very similar (but not compatible with) the MSX computers - although it never found any real success.

Apple III Plus

I'm not sure where I got this one from, but this, along with the Lisa, is one of my favorite computers in my collection. It was quite advanced at time time with a powerful - but poorly named - OS, (Sophisticated Operating System, or SOS), but it wasn't horribly successful in the marketplace - although I gather that "failure" is too strong a word. It seems to have been somewhat forgotten, but I like the case design and, as mentioned, the operating system.

Apple Power Macintosh G3 450Mhz (Blue & White)

Resetting G3 PMU ? Check out Mac Users Guide for more how-to information. Based on the Yosemite architecture featuring a 450 MHz PowerPC 750 G3 processor the Apple Power Macintosh G3 (Blue & White) has 1 MB of backside cache, arrives with 128 MB of RAM, a 32X CD-ROM drive and an ATI Rage 128 GL graphics card. This was the first design that utilized the “fold down door” enclosure that revolutionized the way we interact with our Mac desktops. It is extremely easy to upgrade and introduced Firewire and included both USB and ADB port connectors.

First of the iMac line (See the grey hair? Oops! No, that's just the 2-tone look of the machine)

iMac

This is not the original "bondi blue" iMac from 1998, but one of the later models.

Old Tech: TRS-80 Model 100 (Not Y2K 10 Compatible)

picture of my 1983 vintage TRS-80 Model 100. This 3.1 pound computer was one of the first of what would become known as notebook computers, and proved to be quite popular, selling more than six million units worldwide. Lots of tech-savvy reporters wrote and filed their stories with these units. Quite a few business people did, too. The model you are looking at was "loaded" with 24K (that's kilobytes) of RAM and cost about $1,400. An 8K RAM version sold for $300 less (the unit could accomodate a total of 32K RAM.)

Cray XMP-24 Mainframe

Cray XMP-24 Mainframe Serial Number 115 The predecessor of this machine, serial number 102, became operational at the National Security Agency in June, 1983. Serial number 102 was the first XMP delivered by Cray to a customer site, and thus was arguably the most powerful supercomputer in the world at that time. It was a Cray XMP22, containing two processors and two meagewords (16 Megabytes) of main memory. The machine consists of three towers: a CPU (central processing unit) and main memory tower, an IOS tower (Input/Output Subsystem) and a SSD tower (solid-state storage device, or extended memory. In July, 1987, as part of an upgrade, the original mainframe and IOS were replaced. CPU serial number 115 is a Cray XMP24, containing two processors and four meagawords (32 megabytes) of main memory. .... an overall performance rating of 420 Megaflops. The machine was retired in February, 1993. The mainframe weighs 5900 pounds. 250 kVA of 60 cycle power was consumed by this machine. Also see en.wikipedia.org/wiki/Cray_X-MP In comparison to modern CPU speeds, the X-MP had less than half of the raw power of Microsoft's Xbox console or less than 8% of an Intel Core 2 Duo E6700
