Проект хостится на Google Code: http://code.google.com/p/bk0010/.



Elektronika BK-0010 was a 16-bit PDP-11-instruction-set-compatible Soviet home computer manufactured in USSR from 1985 till early 1990-s. Despite its quirks it was immensely popular in its time. Now it is reimplemented in FPGA and can be played with on an Altera DE1 board. The project is entirely open-source, contains a fair share of Verilog (custom PDP-11 instruction set CPU included), some oldskool C and PDP-11 assembly.

I spent some time looking around the net to find a font that mimics DEC VT220 terminal glyph appearance. There is none. There are some old bitmapped fonts from X11 and probably early MacOS distributions that claim to be DEC fonts, they are functional but their visual quality is lacking and nostalgic value is absent. What I wanted is a font that fills my virtual terminal window with the magic hacking glow...

Накладки во время cc'09 сподвигли меня на реализацию кодера композитного видеосигнала для vector06cc. Небольшая заметка о том, как это было сделано. Без особых подробностей, скорее не руководство, а чтобы самому не забыть. Но вдруг кому пригодится:
ПАЛ-кодер на Altera DE1

Problems with nonstandard VGA output on my Vector-06C FPGA replica made me implement composite PAL output. DE1 board has enough resources to throw in full-colour PAL signal without any additional components. R,G,B wires of VGA output are connected together to cope with 75 ohm load, the rest is done in verilog. This short writeup is Russian-only because there seems to be enough PAL-related info readily available in English. All source code is available in the main vector06cc source tree.
]]> t80quality http://code.google.com/p/vector06cc/source/browse/#svn/trunk/src/T80 T80 Core To Be The Most Precise 8080 To Date Thu, 24 Sep 2009 01:21:02 +0400


8080 has many dark corners. Unlike its more popular successor Z80, 8080 had never been studied enough and most emulator code, and FPGA cores, relied on data from various books and often even word of mouth. Thusly, it's known that DAA instruction doesn't yield correct result after subtration but it's not known why and AC flag has mysterious ways too..
Just recently a few enthusiastic people from a Russian Vector-06c fans forum found a piece of software for Vector-06c which could not be started in any of the existing emulators, couldn't be started in my FPGA replica yet had no problem running in the real Vector-06c at all. After some investigation it turned out that 8080 ALU had AC flag inverted after SUB operation. This involves SUB, SBB, SBI, DCR, CMP, CPI instructions. The pesky ware used the contents of 8080 flags register as a branch address. Ultimately it led to this discovery of auxilliary carry anomaly.

While fixing this issue in the T80 core, which I use in my Vector-06C replica, I discovered a lot of other discrepancies with the original CPU. Thanks to the ultimately inquisitive CPU test written by Ian Bartholomew, 8080 Exerciser, I was able to verify my version of T80 against the baseline set by the real CPU in a real computer.

Probably not an earth-shattering news, but this is a milestone in emulation of 8080 CPU nevertheless. As of now, there are no known tests that could tell my version of T80 in 8080 mode from the real thing. Update your emulators or you're going to lose the edge :) Only my version has these changes at the moment, they had not been merged with the "official" opencores.org version.

One thing worth noting: real CPU tests were done on a KR580VM80A, which is known to be a gate-level clone of 8080, but still not exactly the real thing. If you have a real 8080 CPU computer which can run CP/M 2.2 or similar, please try Ian's test on your computer and send the results to him or to me. ]]> ei1yX3iUT80 http://www.youtube.com/watch?v=ei1yX3iUT80 Motöri the Plotter Video Tue, 01 Sep 2009 18:37:09 +0400

I've had a few of these matrices since I remember myself and always wanted to build something with them. This is a set of "microassemblies": two displays per module, SPI daisychained, each pair is driven by an ATmega8. Pretty neat stuff, really tiny. The drive strength of a mega8 is not really enough to fuel a full column of these ancient antistokes-phosphor-based green LED's rated at 20mA each, but the result is fairly readable in artificial lighting anyway.
