By @Wicho – May 26, 2021 The PiDP-11 – Oscar Vermeulen The PiDP-11, developed by Oscar Vermeulen, recreates a 1975 PDP-11/ 70 at 6:10 scale. It is moved by a Raspberry Pi with the simH emulator and the essential software not just to reveal the memory status of the imitated PDP-11/ 70 on the console, however likewise to check out the position of the switches so that they act on the emulation. It is an intriguing project for computer system geeks, specifically retrocomputers, although it is not of a fundamental level; you have to solder a lot of components to make whatever work, plus the Raspberry Pi software. Since it is one of those things that many of us who have been tinkering with computers for some time have actually burned into our memory. The PDP-11 from Digital (officially Digital Equipment Corporation, DEC) is a design of computer system – or rather a family of computer systems – mythical.
By @Wicho – May 26, 2021 The PiDP-11 – Oscar Vermeulen The PiDP-11, created by Oscar Vermeulen, recreates a 1975 PDP-11/ 70 at 6:10 scale. Well, it reproduces the console from which it was switched on and off and you might do program debugging by analyzing memory locations using an entire collection of switches and bulbs. And is that the cabinet that included the initial CPU determined 181.3 centimeters high by 108 high and 76 deep. In addition to weighing 227 kilos. Why the 11/70? Well, specifically because that console in plum colors and loaded with switches and lights is thought about to be the design conclusion of the range. And in general of microcomputers. It wouldn'' t be out of location on the Enterprise. It is moved by a Raspberry Pi with the simH emulator and the necessary software application not only to show the memory status of the replicated PDP-11/ 70 on the console, however also to check out the position of the switches so that they act on the emulation. In addition, you can connect a VT-220 or comparable terminal to make things even more sensible. If you don'' t have one of those terminals, you can connect it to a computer and use its screen as a screen for the PiDP-11. A vt220 and the pidp-11 – Oscar Vermeulen It costs 245 euros plus shipping, although there is a waiting list due to the fact that Oscar just offers his life to produce a few kits each month. Compared to the $ 20,000 it originally cost, inflation aside, it'' s a bargain. Of course, the Raspberry, its power supply and its sd card are not consisted of in the rate. It is an intriguing job for computer specialist, specifically retrocomputers, although it is not of a standard level; you need to solder a lot of parts to make everything work, plus the Raspberry Pi software application. Beige-O-Vision has a series of 4 videos– in English– covering the entire procedure: PiDP11 Kit Build – Part 1, 2, 3 and 4. But in any case … who stated worry? And when you'' re done, Oscar also has the PiDP-8/ I and the Kim Uno, which play the PDP-8/ I (surprise!) And KIM-1 respectively. Why the PDP-11? Because it is among those things that a number of us who have been playing with computer systems for a long time have actually burned into our memory. The PDP-11 from Digital (formally Digital Equipment Corporation, DEC) is a design of computer – or rather a family of computers – mythical. It was the only 16-bit and first computer produced by the business. It remained in production from the 1970s to the 1990s. They were capable of running Unix – in truth the first version of Unix with that name ran on the 1970 PDP-11/ 20. They supported multiple processes and several users, and all this at a microcomputer cost when mainframes still ruled the Earth. In fact, there are those who state that it is the most popular minicomputer in history. In Bitsavers there is a manual of the PDP-11/ 70 in PDF in case you desire to chatter about it.
