UniDOS v1.37 by Offset, the lord of the DOS to rule them all

-

Something I should have written about much sooner.

These last years several expansions allows you to use mass storage (USB or sd...) on Amstrad CPC, each needing a ROM to use it correctly.

And if you use two of these expansions, you will need to load two ROMs, so less RAM for your Amstrad CPC.

So Offset did write UniDOS and drivers to be able to use another expansion, needing only one ROM with features being the same whatever the expansion. Unidos can manage actually :

Offset also wrote UniDOS Cartridge Creator (v1.4) which is an utility to create Amstrad Plus cartridges equipped with a patched firmware which allows to add UniDOS and its DOS nodes. You can furthermore configure up to 30 additional tool ROMs (such as Utopia, Maxam, Protext..) in the cartridges (compatible with ParaDOS and Burnin' Rubber) without requiring a real ROM board. The tool also let you automatically download the latest UniDOS ROMs from the official web site.

Learning Z80 assembly, are you Rodnay Zaks or Lance A. Leventhal ?

-

To learn Z80 assembly, I only knew the book by Rodnay Zaks, but it seems it's not the best one after reading this Twitter thread. So the book by Lance A. Leventhal would be more didactic and less redundant.

These two books are available on Amstrad CPC Mémoire Ecrite, but beware the last edition of the Rodnay Zaks's book is 1982, the one by A. Leventhal is 1983. Don't download an older version. Rodnay Zaks also exists in french, spanish and german (in 1982 and 1987).

PunyInform v3.5 by Fredrik Ramsberg and Johan Berntsson to write text adventure games

-

PunyInform v3.5 by Fredrik Ramsberg and Johan Berntsson is a library written in Inform 6 to create adventure game (pure text, no graphic support contrary to DAAD) using the Z-machine virtual machine which will run on 8bit computers (or more recent computers too). PunyInform has a parser, knowing of common verbs and a framework to write adventure games.

PunyInform is based on the Inform 6 library written by Graham Nelson. Its goal is to make easily adventure games in Inform 6, with a manual describing the differences between the official library and PunyInform..

Games using PunyInform can be compiled in z3, z5 and z8 format (z3 being the best format for 8bit computers, other formats have more features). Compared to the Inform 6 library, it means that there is no support for the Glulx virtual machine but z3 format is important as Inform 6 doesnt support it.

To compile games written with PunyInform, you should use the Inform 6 compiler maintained by David Kinder. Binaries are available on if-archive. PunyInform needs Inform v6.35 (or more).

They are tutorials to write adventure game with PunyInform (end of the page) and all the documentation including a 8 page cheat sheet (quick reference)..

To try your game after compilation, you can use WinFrotz by David Kinder, to create map easily you can use Trizbort.

And finally, to create an Amstrad CPC and PCW disk image, you will have to use the Puddle BuildTools.



Replacing the Amstrad CPC Gate Array ?

-

The first project for remplacing the Gate Array did start in 2016. It is finished by Gerald, the author of the C4CPC used on CPC+. The difficulty is getting the components to build it...

The second fonctionnal project but still being worked is the one by Bread80, go see his videos on his Twitter account.

Third project more recent, the one by SerErris as a CPLD who was inspired by the thread of the first project.

The Gate Array has also being remade for emulations solutions using FGPA.

A new Gate Array would also mean to be able to add new features !

-

If you still didnt buy the MegaCard to upgrade your MegaPC, there is another useful upgrade. Replacing the Megadrive ASIC on the ISA card as it's an early version with a bug. Beware, you need to be careful when removing the bugged ASIC and putting a new one coming from a Megadrive donor.
