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. Well, it recreates the console from which it was switched on and off and you could do program debugging by examining memory places using an entire collection of bulbs and switches. And is that the cabinet which contained the original CPU determined 181.3 centimeters high by 108 high and 76 deep. In addition to weighing 227 kilos. Why the 11/70? Well, precisely since that console in plum colors and complete of switches and lights is thought about to be the style culmination 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 reveal the memory status of the emulated PDP-11/ 70 on the console, but likewise to check out the position of the switches so that they act on the emulation. In addition, you can link a VT-220 or similar terminal to make things even more sensible. If you don'' t have one of those terminals, you can link it to a computer and utilize its screen as a display for the PiDP-11. A vt220 and the pidp-11 – Oscar Vermeulen It costs 245 euros plus shipping, although there is a waiting list since Oscar just offers his life to produce a couple of kits every month. Compared to the $ 20,000 it originally cost, inflation aside, it'' s a deal. Of course, the Raspberry, its power supply and its sd card are not included in the cost. It is an intriguing project for computer system geeks, particularly retrocomputers, although it is not of a standard level; you have to solder a great deal of elements 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 said worry? And when you'' re done, Oscar likewise has the PiDP-8/ I and the Kim Uno, which play the PDP-8/ I (surprise!) And KIM-1 respectively. Why the PDP-11? Due to the fact that it is among those things that a lot of us who have been tinkering with computer systems for a long time have actually burned into our memory. The PDP-11 from Digital (officially Digital Equipment Corporation, DEC) is a design of computer – or rather a family of computers – mythical. It was the very first and only 16-bit computer system produced by the company. It remained in production from the 1970s to the 1990s. They can running Unix – in fact the very first version of Unix with that name ran on the 1970 PDP-11/ 20. They supported several users and several procedures, and all this at a microcomputer price when mainframes still ruled the Earth. In reality, 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 wish to gossip about it.
