Kees's Computer Home: Garage

Kees and his VAX 11/750

This, the VAX 11/750, is the biggest machine in my home. It had to be parked in the garage, it could go nowhere else. The VAX consists of two cabinets. In the left one are the TU80 1600bpi tape drive and the RA81 450M disc drive. The right one is the 11/750 itself. Click here to read more about my 11/750 machine.

I maintain a site with documentation on lots of old vax systems. Please take a look at www.vaxarchive.org.

AT with Bernouilli drives

This is an original IBM AT. The first 286 system. 640K memory, 512K on the main board and 128K on a card. 30MB very noisy hard disk. 1.2MB floppy drives. On top of it is a box with two Iomega Alpha-10 removable 10 MB Bernoulli drives. The prequel to the zip drive! The keyboard in front of the AT is not original. It is one of the many clones of the first AT keyboard with the function keys at the left side. I have found many IBM key boards with 12 function keys at the top at flea markets but I have never found the first AT IBM keyboard with 10 function keys at left. I still think this is the best keyboard ever made. WP 5.1 was a charm to operate on that keyboard, it became very difficult to hit its f-key combinations fast on a keyboard with the f-keys on top.

TRS-80 Model II (without floppy drive)

The first computer I owned was a TRS-80 Model I. Later Tandy introduced the Models III and 4, wonderful machines you could upgrade to if your Model I gave up the ghost. But what always intrigued me was the "missing link", the TRS-80 Model II. There were impressive stories (and prices) about it in the Tandy catalog, but nobody I knew owned one. Years later, when my "fame" as a computer collector had spread around, I finally got a call from someone who wanted to get rid of a Model II. Bingo!

The Model II in the picture has its 8 inch floppy drive removed for repairs. It should have been in the opening to the right of the screen. If you want to read more about the TRS-80 Model II, click here.

Tandy Model 2000, Model 4

The Tandy TRS-80 Model 2000, a 80186 MS-DOS machine that was twice as fast as the IBM XT and half as compatible. I built a hard disk in to it and used it for a while for word processing and communications. The green screen was very easy to read because of its high resolution and beautiful font. Next to it is the Tandy TRS-80 Model IV.

Tandy Model I, Apple II

The original TRS-80 Model I, with cassette recorder, floppy drive, expansion interface and printer. My first computer. Next to it the Apple II Europlus with an Epson printer made specially for it.

VT1200 X terminal

A DEC VT1200 X terminal, standing in front of 'The Grey wall', The VMS documentation that came with the 750. Next to it the keyboard and monitor of a Wang PC. The Wang 286 that goes with them is by far the heaviest PC I own.

PDP 11/73 clone

A PDP 11/73 clone made by Datelcare. Only the processor card is original DEC hardware, the rest is from clone card manufacturers. It has 2 8 inch SMD drives and works just fine. I still am planning to install 'The Fuzzball' on it and hook it up to the net. It was used at an uiversity nearby for logging of measurements. It got replaced by a number of PCs. I wonder if those PCs still work when they are as old as this PDP!

P3100

I am sure that somewhere in the garage is an example of this computer, the first XT clone from Philips, called the P3100. It is a rebadged Corona computer from Canada. It is the only computer I ever saw that scored a 0.9 x XT on the Norton sysinfo speed test.

P3105/NMS9100

The P3105 was the third XT clone from Philips. It was the first one of a complete line of XT, AT and 386 systems from Philips that all shared the same look. The XT and AT versions also were sold under the name NMS9100 by the consumer products division of Philips, inside they were the same as the P3105. A great many of these P3105s were used at the school where I work. They were 'student-proof' which means indistructible. Some had floppy drives that were unreliable, they only wanted to read expensive floppies, not the cheap white label ones. The machine in the picture was the last one removed from a classroom. It has a CGA monitor. Update: since I have put up this picture I began to get questions about the BIOS setup program of the P3105/NMS9100. But since the P3105/NMS9100 is an XT, it does not have a setup program, setting up is done with switches. But it did have a speed selector program, a clock program and a video selector program. I created a small zip file P3105.ZIP with these programs and added the switch info to this file as well.
