Bally Wizard pinball machine

Isn't this a beautiful pinball machine? (Don't mind the stuff under it.) It's a computer too, if a mechanical one. The Bally Wizard is a meta-pinball machine, since it celebrates the unforgettable movie 'Tommy', the pinball wizard. The machine is somewhat of a wizard itself too, since the calculations it does do not have much relation anymore with the skill of the player. You get the craziest scores every time. Undoubtedly there are a few relays stuck somewhere :)

It's too bad my living room is not too big. I really like old video arcade machines and would love to park an original Pacman machine next to the Wizard, and an old Coke machine and a jukebox too. But that is never going to fit in here.

VaxStation VS2000

On the pinball machine is parked a VS2000 vaxstation, the vax-in-a-lunchbox. It is so small that it should be possible to build a portable VAX with its system board. Yet it is powerful enough to run VMS and NetBSD in an acceptable speed. I use it to format MFM hard disks with, it is the only VAX that can format its own disk. The MFM hard disk controllers of other VAXen and PDPs can then use this disk. A great way to get a ruined disk usable again. Click here for my VS2000 hardware info page.


The VS3500 vaxstation. The fastest VAX in my collection and the only other one (next to the 11/750) that has a SDI hard disk interface. The RA81 disk of the 750 works on the controller in the 3500. Handy to move software.

MicroPDP 11/73

A MicroPDP 11/73. This machine doesn't work (yet). I should get it going, it is a lot less noisy than the PDP in the garage.

Philips P2000C

The Philips P2000C, a portable CP/M computer with a 9 inch display and two 800K 5.25i drives. It also has the optional 'CoPower' 8088 card and could run some ms-dos programs. I have played Infocom CP/M and DOS games on this machine! Every Philips computer collector should have a P2000C, because it has a diskette conversion program that could read and write many of the formats of the Philips 8 bit operating systems, and Rainbow and Kaypro disks too.

SparcStation I

A Sun SPARCstation I. If you collect old computers, sooner or later somebody will apppear carrying in an old Sun. Never say no, they run NetBSD fine and you won't have as much trouble configuring X as with a PC.


A MicroVAX III hiding in a MicroVAX II cabinet. This one has a great deal of options, it was owned by a former DEC service representative. When he finally switched over to the PC he gave me this system as a 'permanent loan', so it wouldn't dissappear as a parts store.

Next to it another Datelcare PDP11/73, this one with a MFM hard drive. It has internal 5.25 drives. I hooked an 8 inch drive to it, so I could convert diskettes.

MicroVAX II, Rainbow, MicroVAX 3300

This is the DEC corner in the living room. On the left a MicroVAX 3300, a recent addition to my collection, haven't had time to play with it yet. Next to it a MicroVAX II with 8 inch SMD drives, one of 300 and the other of 700 MB. For a while this was the system with the biggest hard disks at my place, so it has stored a lot of my files over the years. Next to it a DEC Rainbow PC. This is a dual processor 8088/Z80 system that could run CP/M-80, CP/M-86 and some MSDOS programs. It was also usable as a stand alone terminal. Many were bought to use as a terminal only, because once they were cheaper than a VTXXX terminal. It was a nice development system for Turbo Pascal 80 and 86 programs. The Rainbow CP/M was a special version, it could both run 8088 and 8086 programs.

RS Pocket Computer 1

The TRS-80 Pocket Computer 26-3501 with cassette interface, carrying case and manual. Programmable in BASIC. 24 character alphanumeric LCD. Program capacity 1424 'steps'. A friend used it for a while as a portable telephone directory, his PDA when they weren't called that yet.

Sinclair ZX80

The well-known Sinclair ZX-80. The first really cheap home computer.
