Hi Don,
No, it needs the front panel for:
-MWrite generation
-Reset
-Run
I am thinking of adding those functions on a jumper selection for
version 2, thus making a self contained CP/M board.
Cheers,
Josh

Josh,
Will you 8080 board work without a front panel installed?

Hi Group,
Well, I put up one of these boards fully built and tested on
ebay. I hope to reach some ALTAIR / IMSAI owners that may want to
bring their system out of the closet. If anyone is interested in
following the auction, it's ebay item # 251712707885
I hope it will come up on searches... I couldn't figure out how to
make it "International shipping".
Hopefully, it will drum up some interest in N8VEM too.
Cheers,
Josh
PS. Tom,
I do not have John's Propeller Board. Perhaps John has a blank
sitting on the shelf with my name on it?
I could probably write support for the board, but, it would be
difficult for me to debug without a board to test with.
Cheers,
Josh

Josh...
Do you supports John's Propeller Driven Console-IO Board
on the 8080 board CP/M image?? if no, is this something your
planing on adding??
ADDING THIS WOULD MAKE A GREAT TWO BOARD SYSTEM...
Thanks

I don't have a lot of cards, but I'm primarily using a
DANE-ELEC 1GB card, works fine.
I also tried a Kingston 4GB Micro SD (with the SD adapter) -
does not work.
Another one that simply says "MICRO SD" on it, which is a 2GB
Micro SD with an adapter, does not work.
Another that only has "MINI SD" written on it, which is a 2GB
Mini SD with Adapter does work.
I recently bought some cheap cards from China, the ELITE PRO
1GB Memory Card, they work.
They all work ok on my PC, I'm guessing there's some init
process that I'm not doing correctly for these larger cards.
It's not worth my time to solve the mystery, I just recommend
people use 1GB or smaller.
Cheers,
Josh

Hi Group,
Well, the moment has come for me to stand up and admit I'm
an idiot!
This has come after a long search and struggle to find out
why CP/M 2.2 would not save files correctly.
Apparently in CP/M 2.2, they number the sectors from 0.
While, iirc, in CP/M 1.4 it started at 1.
I spent hours testing my disk read/write routines and
could not find faults.
I even thought my CP/M image got corrupt, and Rich Cini
was very kind to send me another image. I was hoping the
files where different, but that wasn't the problem either.
The whole fix, just really required me to remove a simple
"Decrement Sector" instruction because I thought CP/M used
1 as it's starting sector, where I needed 0.
Sigh... ok, problem solved....
New firmware file and Disk file images (with CP/M standard
files uploaded) on the wiki site at:
http://n8vem-sbc.pbworks.com/w/file/88759892/FIRMWARE%20and%20CPM%20v-disk%20image%20AIR-V12.zip
Cheers!
