Hi! The new N8 (pronounced "innate") Z180 based SBC will be going into beta
test at the end of June (estimated). This is what used to be called the
N8VEM home computer which was mentioned a couple of times in the "FreeCP/M"
thread on comp.os.cpm
The N8 is an "all in one" design with Z8S180, 1 MB SRAM, 1 MB EPROM or 512KB
Flash, dual serial ports, parallel printer port, PS/2 keyboard and mouse
ports, RTC and NVSRAM (DS1302), composite NTSC video (TMS9918A), audio
(AY-3-8910), dual joystick ports, IDE port, FDC port, SD socket, optional
CSIO port, optional RS-485 networking port, and ECB bus expansion. It can
be powered from a 9VDC wall supply or from a scrap PC power supply and fits
on a 10"x6" PCB.
The N8 is wrapping up its initial round of build and test and I will be
ordering the second batch of prototype boards in one week. If you would be
interested in participating as a beta tester please let me know. If there
is enough interest I can expand the prototype board order to accommodate
additional builders. I anticipate the final board to come out sometime this
fall. Note this is a PCB only and you will have to source your own
components to keep the costs low. Schematics, PCB layout, and part list
including supplier information are available on the N8VEM wiki in the "N8"
folder.
Thanks and have a nice day!
