* Schneider Rundfunkwerke AG Euro PC and Euro PC II driver
|
||||
*
|
||||
* Manuals and BIOS files: ftp://ftp.cpcszene.de/pub/Computer/Schneider_PC/EuroPC_XT/
|
||||
*
|
||||
* Euro PC: Computer and floppy drive integrated into the keyboard, 8088, 512K RAM, there was an upgrade card for the ISA slot that took it to 640K, single ISA slot
|
||||
FD360 external 360K 5.25" DS DD floppy, FD720 external 720K 3,5" DS DD floppy, HD-20 external harddisk, internal graphics card is CGA or Hercules, 64KB VRAM
|
||||
* Euro PC II: like Euro PC, socket for 8087, 768K RAM on board, driver on Schneider DOS disk allowed the portion over 640K to be used as extended memory or ramdisk.
|
||||
* Euro XT: conventional desktop, specs like Euro PC II, two ISA slots on a riser card, 102 key seperate keyboard, internal XT-IDE 20MB harddisk, connector for FD360 and FD720 was retained
|
||||
*
|
||||
* Only BIOS versions >2.06 are supported so far because of changes in the memory management, according to https://www.forum64.de/index.php?thread/43066-schneider-euro-pc-i-ii-xt-welche-bios-version-habt-ihr/
|
||||
* BIOS version 2.04 has been encountered, but is not available online
|
||||
*
|
||||
* To get rid of the BIOS error messages when you first start the system, enter the BIOS with Ctrl-Alt-Esc, match the RAM size to your settings in MAME, set the CPU speed to 9.54MHz
|
||||
* and the graphics adapter to Color/Graphics 80, internal graphics off
|
||||
*
|
||||
* To-Do: * An external 20MB harddisk (Schneider HD20) can be added to the PC and PC II. This is a XT IDE drive. The BIOSs contain their own copy of the WD XT IDE BIOS that can be activated from the BIOS setup menu.
|
||||
* (load debug, then g=f000:a000 to enter formatter routine)
|
||||
* * emulate internal graphics, but AGA is not quite the correct choice for the standard graphics adapter (it's a Commodore standard), as the Schneiders are only capable of switching between Hercules and CGA modes.
|
||||
* * The PC 2 and XT have 768K of memory that can be configured from the BIOS setup as 640K, 640K+128K EMS and 512K+256K EMS. The EMS options are not visible in our emulation and loading the EMS driver fails.
|
||||
* See http://forum.classic-computing.de/index.php?page=Thread&threadID=8380 for screenshots.
|
||||
* * use correct AT style keyboard for XT
