Hi,
Good news on the S-100 8086 CPU board.
First confirmed working installation "in the field" AFAIK.
If we've gotten this far, I think demonstrating a working CP/M-86 will be
along shortly.
John already has CP/M-86+ running in the lab.

Thanks and have a nice day!

Hi and Seasons Greatings.
All the best to everyone and their families.
I've just completed my S-100 8086 board.
See photos at:
http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder¶m=8086
Everything went smoothly except a missing K8 jumper 1-2 gave me some grief
for a while.
I have a V30 CPU and a 24MHz oscillator (8MHz clock) without any problems.
I'll try 10MHz next when I get a crystal.
Next step is to get CPM86 and MSDOS going.
Thanks for another great board John and Andrew.
Leon

What are the possibilities of running DOS of some sort and a homebrewed
VGA board?

Hi Dave! Thanks! The possibilities are pretty good if you are patient.
John and I are developing two new boards to address this very issue.
The current S-100 8086 CPU board runs CP/M-86+ and MSDOS 4.01. I imagine it
could run FreeDOS as well if someone were to port it.
However for really good PC like compatibility you'll want these two boards
we are working on:
1. S-100 MS-DOS Support board
Adds the essential guts of a PC/AT motherboard minus CPU and RAM to the
S-100 bus. In development and approaching initial "production" status in
probably 6-8 weeks.
http://s100computers.com/My%20System%20Pages/MSDOS%20Board/MSDOS%20Board.htm
http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder¶m=S-100%20MS…
20Support%20Board
2. S-100 VGA
Adds a GD5420 Super VGA chip to S-100 bus. Has just started development.
John has the initial prototype for build and test -- no ETA.
http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder¶m=S-100%20VGA
In theory, with the above boards with a S-100 8086 CPU board and S-100 4MB
SRAM you could build a more or less PC/AT compatible S-100 system.
This should dramatically add to the amount of available software for your
system.
There is also a S-100 80286 CPU board in development. All the S-100 CPU
boards are or will be TMI compatible to allow multiple CPU bus masters.
Apparently at least one N8VEM builder has a system which is demonstrating
S-100 8086 CPU and S-100 Z80 CPU dual masters.

046
This is not the only example but the most recent and has readily available
information online.
It is an all S100computers.com/N8VEM system except for the motherboard.
Unfortunately the number of S-100 boards we've got now (24) greatly exceeds
the number of slots (8) on the S-100 backplane PCB.
I guess that means a larger S-100 backplane PCB is forcing its way into the
job queue. ;-)
Hope this helps. Please let me know if you have any questions. Thanks and
have a nice day!

I don't see it elsewhere on the board. That might be a cause of trouble
later on (see Sun workstations).

Hi Dave! Thanks! The S-100 MS-DOS Support Board uses a DS12887 RTC which
contains an internal battery.
They last about 10 years or so. Please a socket the chip and if it runs out
of backup power just replace it.
I suppose it would be easy enough to add a connector for an external
battery. Let's discuss with John.
We are open to requests on the design but if you have input we should
probably discuss it on N8VEM-S100 mailing list since it would be off-topic
here.
Thanks and have a nice day!
