Small update, here are pics of the K200 memory module which adds 64KB of RAM to the onboard 64KB. The module itself has been included in the DMV driver for a long time, the pics are just for completeness' sake.

NCR DMV K200 memory module

LN, were you able to read the ROMs of the DMV's harddisk controller I sent you?

Not yet. Have to get a bunch of stuff done for VCFE in a week or so, but after that I should have time.

Thanks to Sandro Ronco for adding the DMV's harddisk controller!
This was the last missing bit to DMV emulation. While experimenting with the new addition, I found that the cursor is wrong, it's a solid block but should be a blinking underscore.

I'm re-acquainting myself with the setup of the harddisks. The partitioning scheme is relatively inflexible (originally 10MB harddisks were used), allowing the CONFIG program to set the number of harddisks and then the number of partitions on those harddisks leading to single 10MB partitions or dual 5 MB partitions per hard disk.
CP/M is not bootable from the harddisk.
There are later DOS utilities that can create a single 20MB harddisk parition per disk but this is incompatible with CP/M partitions.
I'm trying to recreate my old setup that utilised most of a 2x20MB configuration. I'll add a how-to when I have my stuff running again

68bit gets credit for adding the WD1000 device that made this possible as well

Definitely! It could also find a home in the Kaypro 10

I checked the DMV drivers to see if the recent µPD7220 changes were having any ill effects.
The cursor should be a blinking underscore, but ... this has been a solid rectangle going at least back to 0.164 and it has a "//TODO" in the source,
so not really a regression

The DMV driver seems to have lost the ability to draw the graphics in AutoCAD between 0.235 and 0.236 (there was a µPD7220 change for that release).




I have a HD image set up to replicate the issue. The DMV.BAT file in the archive gives a nicely maxed out configuration for the machine after you adapt the file paths to match your MAME setup.

Boot into DOS, enter "CD ACAD", "ACAD", type option "2" and the drawing's name, e.g. "NOZZLE" or "COLUMBIA".

Fixed.

Thanks crazyc!

Can't see it, did you forget it ?
