MAME64GRID Rev. 4
MAME64 version for GRiD Compass computers emulation

MAME ver 0.220 GRiD-ONLY - 08/13/2020 13:11:18

Works:

-Emulation GRiD Compass 1101
-Emulation GRiD Compass II 1129 and 1139 (bad)
-Bubble Memory, floppy disks (including formatting) and hard drives
-Serial port (NOT CHECKED)
-DMA (while it does not block and therefore only works if the device has zero latency)

Does not work:
-Modem
-ROM chips
-Machine ID
-Access to Bubble Memory in Compass II 1129
-Formatting Bubble Memory in Compass II 1139
-Boot GRiD OS from Bubble Memory with connected hard drive
-Intel 8087 (emulation broken)
-Hard disk for Compass II 1139 (HDD315.IMG image for booting from HDD is not completed yet)

Use MAME64GRID Launcher to run - RUNGRID.EXE
If at startup you have a black screen, restart, such a bug happens

Booting from devices to GRiD Compass (hold the key until the logo appears):

B - Bubble Memory

F - Portable Floppy

H - Hard Disk (Press when using HDD version)

R - ROM Memory

ATTENTION: In this version, switching to full screen mode is performed using the keys
                                 LCTRL + LSHIFT + LALT

Also, for better display, the emulator screen is doubled in resolution
                          
                        ! The CODE key is replaced by the ALT key!
