Amstrad CPC CRTC Compendium v1.3 by Longshot and the AMSpiriT emulator by Dmanu78

-

Longshot has released version 1.3 of the Amstrad CPC CRTC Compendium (beware, the english version isn't definitive, only the french one is actually) which is a documentation about the CRTC 6845 (and some others circuits). Note that the CRTC is a generic component used in several computers including the IBM PC.

As seen on CPCRulez, the AMSpiriT emulator by Dmanu78 is respecting by a great margin the SHAKER tests by Longshot than other emulators. SHAKER is a program designed to run on CPC machines produced by AMSTRAD in the 80s-90s. The objective of this program is to carry out extensive tests on the video circuits of this machine. These video circuits are the GATE ARRAY and the CRTC 6845. AMSTRAD produced several series of GATE ARRAY and used CRTC models produced by different manufacturers (HITACHI, MOTOROLA, UMC, AMSTRAD). This has been causing compatibility problems on operations that exceed the functional specifications of these circuits. The identified CRTCs are numbered from 0 to 4.

So AMSpiriT is better especially if you like to see Amstrad CPC demos, and can't be bad either for games. I don't have the time to test extensively all Amstrad CPC games, but for sure I will take time during the Benediction Coding Party #2 to use it.




WIP Missile Command by Cyril GOURET and TITAN

Missile Command is an Atari arcade game released in 1980, and in 1981 for the Atari VCS 2600, ported by Rob Fulop, which sold over 2.5 million copies.

Cyril GOURET (music, code and sprites) et TITAN (loading screen) are working on a WIP remake of this classic for Amstrad CPC. A working demo was available at the RGC 2022 meeting, the final version isn't available for the moment.

ZCN 1.4, CP/M for the Amstrad Notepad NC100, NC150 and NC200 by Russell Marks

-

After having released a new version of his Amstrad Notepad NC100, NC150 and NC200 emulator, Russell Marks has just released a new version of his version of CP/M for these same machines : ZCN 1.4, the new features are :

  • NC150 support, with a custom zcn150.bin kernel. As with the NC200, this is not as complete as the NC100 support. Also, it has only been tested under emulation
  • Internal ramdisk support on NC200 and NC150, so you can use ZCN on them without a memory card (to some limited degree). This is really only intended to be used if you lack a memory card - you switch between memory card mode and ramdisk mode using the "ramd" command
  • Improved keyboard layout support via keyb, supporting Danish, French, German, Italian, Swedish, and US keyboard layouts, in addition to the old UK and Dvorak. All supported keyboard layouts can be used on any NC model
  • Preinstalled memory card images for NC100/NC150/NC200. These are intended for use with emulators like nc100em/MAME/RC2014, but they should also work on the real thing if you have the means to write them correctly. (Serial link installs are still supported, of course.)
  • Support for booting from floppy disk on the NC200 - this uses David Given's floppy-boot code from FUZIX, almost unchanged. ZCN itself does not support the floppy disk, so this just loads ZCN and a small ramdisk image then boots it
  • Support for displaying some non-ASCII characters, specifically some from the old DOS code pages 437 and 850 like in the ROM software, as well as the euro sign character from 858. Only a few dozen characters are supported (!) and you need to run keyb beforehand (i.e. since boot) for this to work
  • NC200 time-reading and time-setting support, meaning that e.g. time and timeset work
  • The man command now uses ZX0 compression - the data file is smaller, man.com is smaller, and man pages load faster
  • Certain .com files in the support directory, like QTERM, are now also provided in versions using ZX0 compression. So for example, the ZX0-using version of QTERM is 5k smaller. ZCN comes with a "zx0com.bin" file you can prepend to a .zx0 file to run it in this way (limited to .zx0 files of 16k or less)



New batch of Albireo cards made by Zik (originally by PulkoMandy)

-

PulkoMandy is the author of the Albireo expansion card for Amstrad CPC which lets you use mass storage (USB and/or SD card) and a serial port.

With the agreement of PulkoMandy, Zik is going to make a new batch of cards (beware without the serial port). It's even possible to use two cards (but needds a cutter and some soldering).

You will need a ROM board and one of the ROM which can manage an Albireo, Unidos for example. The estimated price for the card, shipping cost and maybe a SD card is 30 euros.

If you are interested, go write on the CPCWiki's thread.
