What is DiagROM?
DiagROM is a diagnostic tool for the amiga computers.
And it is to be used on defective machines, trying to help no-boot situations etc.
You simply replace the Kickstart roms in the Amiga with the DiagROM. and when poweron. your Amiga will start a diagnostic software. It will try to dump info on the serialport (and actual menus etc aswell) while also trying on the screen.
Changelog:
- RTC Test improved with OKI Chipset support (but RTC test still is kind of buggy)
- Remade the autoconfig handling for much better ZorroIII support etc.
- Possability to turn on/off cache in manual memortedit (this WILL crach your machine on 68000/68010)
- Added an experimental “no chipmem” screen to try to figure out biterrors with rasterbars. (dark bar=dead bit, light bar=working bit)
- Added support for Amiga 1000 with a limited version of DiagROM.
- Parallel and serialporttests using SysTest compatible loopback adapters.
- Diskdrivetests.
- And.. some internal changes and stuff I actually forgotten.
Updatehistory:
- 2017-10-01:
- Long time since last time:
- Added tests for Parallel and serialporttesting using SysTest compatible loopbackadapters
- 2017-07-30:
- Added possability to run on A1000 as bootstraprom. I have removed moduletesting and gfx test-screemn to save space.
- Some additional bugfixes.
- 2017-07-06:
- Fixed a bug, when setting DTR high I accidentally put Dikdrive motor on!
- when no chipmem is foundand no fastmem, instead of just flashing a green screen, it now checks memaddr $400 and shows in stripes biterrors. bright color=bit working, dark=bit error. evbery 15 frame it flashes and steps +4 bytes of memaddr to check
- 2017-06-17:
- Oh! yes long time. Now DiagROM is opensource avaible at https://github.com/ChuckyGang/DiagROM
- Totally rewritten Autoconfig, now handles Z2 and Z3 and should be working. if you get stuck in a loop (autoconfig not working) it
- will halt after 32 “boards”. Also in ManualEdit mode, I have inlcuded a function to turn on/off cache. to debug cacheissues on CPU Cards.
- BE CAREFUL! this WILL crash if you run it on a 68000/010
- Also fixed bug of garbage in menus.

Jean-François DEL NERO (who’s behind the HxC SD Floppy Emulator) recently has released a version of the HxC emulator firmware that is compatible with the STM32 chip used in the Gotek floppy emulators.
This means that the great functionality of the HxC SD emulator is now available on cheaper and more widely available hardware.
The bootloader to convert the Gotek floppy drive in HxC compatible must be purchased on the website HXC 2001 by sending an email to Jean-François DEL NERO. The price of the bootloader is one-off 10 Euro per Gotek that you want to update. Future updates of the software are free and can be made from a USB stick
The HXC Usb (Gotek) firmware supports: 
+ many more….

Atari 600XL Repair & Memory Upgrade
Defect:
- Keyboard unresponsive – Dead.
- Keyboard “A” Key Dead.
Repair:
- Replacing 2 x CD4051 (U22/U23)
- Sprayed R-11 Contact Cleaner inside the push button of the “A” key.
Enhancements:
- Upgraded the RAM memory from 16k to 64k (memory upgrade requires 3 short lengths of wire and two memory chips: HM50464P or equivalent 4464 to provide a full 64K).
Gallery:
Very nice adapter designed by Rolo that allows you to use the Rolo Multi-Cartridge also on the Interton VC 4000 console.
Gallery:
This is a very simple composite video and audio mod for the Interton VC4000 console.
You need to remove the RF modulator (recommend to removing it completely) by removing all pins and then connect the video (V) Audio (A) and ground (G) signals like the photo and then use the same hole of the RF cable for the new video and audio cable.

Olivetti Prodest 128S (Acorn BBC Master Compact) Modding
I found in the box of the rubbish dump two Olivetti Prodest 128S that was given to me long time ago by a dear friend: Andrea Pierdomenico.
Both computers are without the Floppy Drive and Power Supply external module.
I chose one of two in a better conditions and i did a modding to use it with a VGA Monitor and SDCARD instead of Floppy Disk plus some extras.
Work that has been done:
- Replaced the lame Olivetti ROMS (EPROM 27C512) with the original one from Acorn BBC Master Compact (release MOS 5510)
- GBS8200 v4.0 for VGA Output installed inside the case.
- Removed the Input Video signal connector (YPbPr) of the GBS8200 because they cause problems to closing the case.
- Capacitor FIX for GBS8200
- Installed a Power Switch.
- Cutted two pcb track for the Power Switch.
- Installed a VGA Connector.
- Replaced the Power LED (RED) with a GREEN LED.
- External power supply (5v / 2.5A).
- Installed a potentiometer (10K) to adjust the speaker volume.
- Cutted one pcb track for the potentiometer, otherwise the external volume adjust don’t work.
- TurboMMC installed (see the pinout for the internal installation).
- Installed TurboMMC Eprom.

The Commodore C64C replacement case is very nice like the original one.

… so if you are not looking for the absolute perfection, i would recommend it to everyone.

Hoxs64 written by David Horrocks is a Commodore 64 emulator for Microsoft Windows 2K/XP/Vista/Seven (DirectX 9+)
The emulator substantially reproduces this legacy machine in minute detail.
Changelog:
- CIA serial and CNT timing improvements thanks to test programs written by Mariusz.
- Added VIC-II colour palette user configuration dialog box.
- Added command line options (see hoxs64.txt) to support the VICE 64 testbench.
- Changed the colour RAM reset pattern to use bytes $0C and $03 as per the same C64C whose RAM reset pattern is already used.

CBM prg Studio Version 3.11.0 is released. There are a lot of new features in this version. I’d really appreciate it if you report any bugs you find or have any suggestions/comments.
CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 / VIC20 or PET if you’re feeling brave and have the right kit.
CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.
It was also a good opportunity for a face lift and to add some new features, such as:
- Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
- Tabbed MDI.
- Syntax highlighting.
What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.
New features in v3.11.0:
- Assembler:
- CTRL+Double click on label or variable will take you to its definition.
- Mouse over a directive to get a tooltip of its usage.
- Control/screen codes can be embedded in text strings.
- Sprite Editor:
- Number keys for quick colour change.
- Screen Editor:
- Quick colour change.
- Screen editor can generate data to basic string array.
- BASIC:
- Super Expander basic extension for VIC 20 projects.
Bugs Fixed:
- Assembler:
- Having ‘*=’ in a comment causes an error
- Macros weren’t appearing in the macro viewer
- Multiple macro parameters in the same line were being ignored.
- BASIC:
- Incorrect line warning length for VIC20 projects.
- Screen designer:
- Crash when exporting C128 screens.
- Sprite Editor:
- Fail when importing from listing when the target line number was also in another part of the listing.
- Character Editor:
- Fail when importing from listing when the target line number was also in another part of the listing.
See the help for a complete list of new features and fixed bugs.
Note In this version, each target machine can have its own default project directory. If you are upgrading from a previous version (before version 2.5.1) of CBM prg Studio you may be asked to set up your project directories again. Your current projects will not be affected.

The Multi-cart by Rolo was designed to to hold a variety of Dragon 32-64/CoCo 2 rom cartridge based programs, which are running directly from the eprom at address range $c000 to $ff00.
The cart holds up to 64 8k-roms. It can play roms with a size of 1k to 16k. You simply select a memory slot from 00 to 63, press RESET on your Dragon, and the program launches.
This enables you, to use your Dragon simply without further hardware setup: no cables, no drives, no extra PSUs, no controller-carts.
The Dragon/CoCo 2 Multi-cartridge now can also be used for other systems.
Currently there are three Extension Cartridges (adapters) available:
- VECTREX.
- Odyssey 2/PHILIPS G7000/G7200/G7400.
- INTERTON ELECTRONIC VC 4000.
A compilation of rom-files for all four systems can be burned on a single eprom (27C4001), adding versatility to the device.
