From: lynchaj on 14 Jan 2010 17:38 Hi! If you are interested in building your own homebrew Z80 CP/M single board computer please contact me. I have many PCBs available for the N8VEM SBC and all the peripherals. You build the computer yourself using the PCBs you either make them yourself or you can buy the low cost ECB Eurocard PCBs from me. There are several PCBs available: SBC (Z80 CPU, 512K SRAM, 1MB ROM, serial port, parallel port, RTC, and ECB bus interface) ECB backplane (6 slots) ECB bus monitor (with bus status, address trapping, and single step modes) ECB prototyping board (with IO decoding circuitry) DiskIO (floppy and IDE interfaces) Zilog Peripherals (CTC timer, DART dual serial, dual PIO with 4 eight bit parallel ports) VDU (video interface with PS/2 keyboard, PS/2 mouse, and parallel printer port) 6809 host processor (128K SRAM, 2K ROM, expansion bus) There are a number of S-100 boards available also with more on the way. S-100 backplane (6 slot with active termination) S-100 prototyping board S-100 buffered prototyping board S-100 IDE board All the design information for the N8VEM hardware and software is freely and publicly posted. Please feel free to join us if you would like to participate. http://n8vem-sbc.pbworks.com/ http://groups.google.com/group/n8vem Thanks and have a nice day! Andrew Lynch

One of the N8VEM builders just posted this photo of a completed system. http://n8vem-sbc.pbworks.com/f/n8vem_case_nb.JPG The homebrew computer is functionally complete with all the components you would expect of a system of the late 1970's early 1980's era.

Much more fun to emulate every processor that has been in major use since the beginning (practically) using the MAME emulator. And it plays games too. All of them, in fact. |
