z80pack Desktop 2014 1
This is how my Desktop looks like 2014, when working on z80pack. The physical maschine in this case is running Windows 7. On the right you see an Oracle Virtualbox running Debian Linux 7.0.0 with the IMSAI machine 2D front panel running IMDOS.
On the left you see an Oracle Virtualbox runnning OpenSuse Linux 13.1 with KDE desktop with the IMSAI machine 3D front panel running IMDOS. I just made the line printer working for the IMSAI machine. Same as cpmsim the emulated IMSAI now can print into a file on the UNIX host.
Then on the left the green terminal is a Windows Cygwin terminal running cpmsim just booted with CP/M 1.3.




z80pack Desktop 2014 2
Here you see the first two complete computer systems, that could be owned and operated by individuals at home, the Altair 8800 and the IMSAI 8080, running CP/M. Several tenthousand units of each were sold to individuals, who used them to learn operating and programming such machines. And then many of them went into the IT business, to build the most advanced machines and software we now have in the 21th century. I have been part of that since 1974, when I got access to digital computer systems, 4 decades by now.




z80pack front panel machines under Windows
The front panel machines running native on a Windows 7 system, for those who want to stick with Windows. An archive with ready to run binaries, scripts and disk images with CP/M versions for the maschines is available in the download section.




z80pack front panel machines under OS X
Just build under Apple OS X, works well and looks great on a Retina LCD.

Altair 8800 running with a vintage Cathode terminal emulation




z80pack front panel machines under OS X
Here is a much better one together with Cathode terminal emulation. The terminal emulation has many settings and I needed a while to figure out a good font and size for an appropriate x:y ratio, so that the terminal really looks like a cathode tube screen. On the terminal I opened the CP/M 2.2 BIOS assembler source for the Altair with WordMaster editor, everything fully working of course. The desktop picture came with the Apple system and I think, this one is a good setting for the ancient machines, I really like this picture a lot.

PS: In the beginning DRI was named Intergalactic Digital Research, and MITS, the company that developed the Altair machine, build model rocket kits before. So here you have it, intergalactical ;-)




z80pack front panel machines under OS X
The Altair together with Egan Ford's greenbar teletype emulation. This is a realistic teletype emulation with ca. 10 cps transmission speed and sound support. One can't use a visual editor with a slow teletype, so here CP/M ed is used, that is the hardware we had way back then. And now go learn ed and use this stuff to write some software, then you really know how that was 40 years ago.

The IMSAI machine running BASIC with a teletype.




z80pack front panel machines under FreeBSD
Works too.
