The awesomeness: Amiga hardware news - galore! (2/2)

Even more pure awesomeness. The Amiga community is without a doubt the most active and knowledgeable in the retro scene.

Paul Rezendes' Amiga 4000 replica mainboard

We've already reported about this project - and, yeah, it's done, thanks to Paul and the community!

The GoFundMe campaign has reached and even exceeded the amount of money required, and Paul Rezendes was pretty quick at getting the first boards produced and tested. By now the files created have been released to the public, and you can even order a board from Paul.

...and arananet's Amiga 4000 daughterboard!

With the Amiga 4000 replica mainboard done (see above), and John Hertell's A3660 Amiga 4000 CPU board done, you might be wondering "cool, but I still can't build my Amiga 4000 without a ..."

Daughterboard. Wonder no more.

Eduardo Luis Arana has published the files required to build a updated daughterboard. The ISA ports has been removed, and it now includes a 15KHz VGA display connector to use with a breakout / backplate bracket. And it has some nice fiery design on the backside.

Amiga S-video board

The Amiga's video connectivity features, while being highly convenient about 25 years ago, have turned out to be somewhat problematic today, and every update to them is warmly received.

http://electronics.chroma.se/svideo2.jpg

This board connects the any Amiga's 23-pin display output, and has a composite video, an S-video, and a 15KHz VGA output connector. Picture quality is claimed to be higher than Amiga-built-in outputs, especially using the S-video output.

Here we have another little success story regarding teamwork among Amigans: this circuitry is the one being used in John Hertell's ReAmiga 1200 for video output - nice! (see part 1 of this article)

K1208 and A1200 SDE+ 8MB FastRAM, SPI (SD, Ethernet) boards for Amiga 1200

Derived from Stephen Leary's TF328 project by Kipper2k, and further developed by Solidcore and Mike Stirling, these are two similar expansion boards for the Amiga 1200.

The specifications read as follows:

• 4MB/8MB FastRAM jumper (4MB for PCMCIA support)
• microSD card slot, up to 4GB FAT95 (FAT/FAT32) formatted cards (SPI 8MHz)
• Ethernet ENC28J60 SPI module support (SPI 8MHz)
• Real-time clock
• 2800+ dhrystones on stock Amiga 1200 (14MHz 68EC020)

The situation with these boards is a bit unclear, no conclusive information about final development and availability could be found. It looks as if currently only the software for the cards (drivers and firmware) has been released to the public.

Inexpensive A500 hard disk interface

A nice little addition for your quick harddrive needs might be this straightforward Amiga 500 harddisk interface. It requires a floppy disk to boot from and has been successfully tested with Kickstart 1.3 and 2.0.

Now this one has a feature that cannot be praised highly enough:
As you can see in the picture below, it has two expansion port connectors, one after another - the front one is an adapter to standard 2.54mm pin grid connector, and the other one is the pin grid connector mounted to the PCB. As the author says in the README file: "[...] future expansions will be developed with pin headers as their main connector." Huge sigh of relief. Finally someone starts to get rid of proprietary, hard-to-obtain connectors, and replaces them with widely available, future-safe solutions. One small step for an expansion board, hopefully one giant leap for Amiga-kind.

https://github.com/AmigaPorts/a500hdd/blob/master/doc/nib.jpg?raw=true

As of now the latest commit to the GitHub repository happened just 11 days ago, so this is apparently under active development.

BONUS HARDWARE:

GRETA FastRAM/microSD/ethernet expansion board for Amiga 500

A couple of years ago, Martin "endofexclusive" Åberg from Sweden created GRETA, a Xilinx Spartan FPGA-based expansion board for Amiga 500. It's build to add 8MB SRAM, a microSD slot, and 10/100MBit ethernet controller to the Amiga. The project files have last been updated on August 1st 2016, and hardware programming is still incomplete - currently only RAM expansion is supported.

GRETA seems to be some kind of forgotten gem among Amiga hardware expansions - the specifications look fantastic, it contains all of the features one would like to have on a single PCB. As it seems, there's only some programming required to make things work.

https://github.com/endofexclusive/greta/blob/master/doc/mounted_components2.jpg?raw=true

Wouldn't that be a nice project to pick up and give it some love?

Looking at the other amazing expansion boards that have come out in recent years, probably even an unexperienced programmer would be able to add ethernet and microSD mass storage support to the device, there's plenty of material out there to study and learn from.

If you're interested, go to GitHub, and start building your GRETA:https://github.com/endofexclusive/greta

The awesomeness: Amiga hardware news - galore! (1/2)

It sounds too good to be true, but in these cases it isn't a hoax. There is a lot, and may I repeat, A LOT going on in Amiga hardware world... In fact it's so much I've split this into two parts.

7-bit's SPI controller for the clockport

On April 24th 2018, 7-bit Retro Electronics announced a new product: The "SPI MasterBus CP" controller for the clockport.

SPI is a simple, flexible, fast serial data interface that allows multiple devices to be connected. It's used by numerous types of devices across all computer platforms, e.g. as an interface to memory card readers (SD, SDHC, CompactFlash, ...), ethernet controllers, flash memory, for CPLD programming, and many more applications.

That makes a fantastic addition to the Amiga's capabilities!

Here are some "SPI MasterBus CP" specifications:

Designed for Amiga A1200’s clock port
SPI bus clock speed: 25 to 195 kHz
Full-duplex data transmission
Up to 4 devices with Slave Select lines

Built-in software will allow you to manage several characteristics of the controller.

Here's an early video showing SD-card access in action:

Jeroen Vandezande's Amiga 1200+ mainboard

With increasing age, Amiga 1200 mainboards (among others) run the risk of taking damage from leaking capacitors, and of course over a timespan of about 30 years there are a lot of other factors that may shorten - or quickly end - a mainboards life.

Wouldn't it be nice to just have the opportunity to purchase or make a new one?

This is one of two projects (see below for the other one) recreating the Amiga 1200 mainboard, Jeroen's "Amiga 1200+" is an updated version with some changes.

The project is covered by Creative Commons license, and you are free to build your own mainboard!

Here's a list of changes compared to the original Amiga 1200 1D4 mainboard, taken from the project website:

• Gayle, Budgie and the DRAM have been removed and the functionality has been moved to a daughterboard. This board can also contain a CPU.
• Video output has been moved to a seperate output board. This board get all Lisa output signals and also all the typical Zorro signals. This means that an RTG card can be developed.
• The PCMCIA slot has been removed and in the free space a power switch, boot selector switch (DF0:/DF1:) and a uSD card slot have been added. 
• A single supply universal power input has been added. (15V - 36V)
  From this the following voltages are created:
  * 5 Volts: main power rail 5 Amp capable
  * 12 Volts: 1 Amp capable
  * 3.3 Volts: 0.5 Amp capable (for daughter boards)* 1.2 Volts: 0.5 Amp capable (for daughter boards)
• Two PC standard 3 Pin fan headers are added to the board. 
• Terrible Fire compatible SPI port for network chip 
• Extension board connector for mouse/joystick. (One is in development that has USB Mouse and two classic DB-9 connectors and autoswitches when fire button is pressed.)

The "Terrible Fire compatible SPI port" is an especially nice addition: it shows that Amigans work together - way to go!

Now head over to Jeroen's website, and start building your enhanced Amiga 1200:

John Hertell's Amiga 1200 replica and ReAmiga 1200 mainboards

The other project recreating the Amiga 1200 mainboard comes from John "Chucky" Hertell, well known Amiga hardware guru.

He had already created the A3660 Amiga 4000 replacement CPU module (see http://wordpress.hertell.nu/?p=537 and http://eab.abime.net/showthread.php?t=89200 if you want to know more), and asked the community for his next reverse-engineering project, which turned out to be the Amiga 1200 mainboard. Well, about two months later, and with the help of other members of the Amiga community, Mr. Hertell had a clone of the original 1D4 version mainboard in Gerber file format!

But he didn't stop there, adding some modifications to the board - here's a list of changes:

• Supports round and square powerconnector
• New reworked composite video logic, with additional S-Video support
• RF-Modulator removed and replaced with optional buffered VGA connector
• Selectable SEL signals for floppy
• Optional NMI (IRQ7) possibility
• Resetheader
• A500 compatible keyboard connector (currently untested)
• Support for the Ratteswitch with solderoles for required signals so no need of a socket on CIA
• Extra powerconnectors for +12 and +5V fans, and extra powerconnector close to CPU slot
• PCMCIA reset fix
• Optional onboard LEDs where LED and +5V are separated also optional “opt” led, with jumperwire for PCMCIA activity LED

 

http://wordpress.hertell.nu/wp-content/uploads/2018/08/A1200pcb.jpg

Well, what can you say - another awesome job by Mr. Hertell.

Check his website for complete first-hand information, and files required to build your own Amiga 1200 or ReAmiga 1200 mainboard:

Note that you can also buy ReAmiga 1200 PCBs from Mr. Hertell - income from these sales will partly be donated to Swedish children cancer fund. See link above.

 

Commodore Amiga AA3000 / A3000+ recreated

Both Matthias 'Matze' Heinrichs' and Christian 'Scrat' Euler have recreated a legend: an AGA-chipset equipped Amiga 3000!

Sadly, there's no open source re-creation (yet?) of the mainboard, probably due to technical difficulties (8-layer board) - but nontheless, this is another great example of the capabilities of the Amiga community. Who would've thought we'd see these ultra-rare machines outside of Commodore's laboratories one day?

Another success story: New cases for Amiga 500!

Philippe Lang and A1200NET, who already created new Amiga 1200 cases and keycaps are going to create professional molds for new compatible Amiga 500 cases.

It's another amazing success story from the self organizing, crowd-funding Amiga-scene: According to the Indiegogo project page, as of today $186,734 USD have been raised, and the project was 112% funded on May 31, 2018!

 

These new cases feature a number of improvements over the original ones, apart from being brand-new:

- screwholes with metal threads
- immune to UV-light
- prepared to house a Vampire 500 V2 or Raspberry Pi 3 mainboard
- or of course an original Amiga 500 mainboard
- Vampire ports extender, allows routing of internal LAN / USB / HDMI / SDcard connections to proper outlets (e.g. disk drive opening)
- different colors available: white, black, light blue, orange, and more
- signatures by Amiga celebrities like Dave Haynie and David Pleasance, among others
- metal case badge, floppy buttons, rubber feet, and trapdoor covers included

The whole thing seems to be well on it's way, and mass production of cases is planned towards the end of 2018, to be shipped in April 2019.

Of course if you want to support the project you still can, there are numerous packages available for you to claim - from "Unique Solo" - one case - to "Quad damage" - four cases - or silver and gold metal coated editions, or a beautiful "Scourge Of The Underkind" collector's edition.

Oh, and there's even more: if the project reaches it's "stretch goal" of $189,000USD, project backers will receive new Amiga "tank"-mouse cases, too!

Amiga 4000 opensource mainboard: alive and well

Paul Rezendes' Amiga 4000 mainboard replica is moving along quite nicely. 

Paul Rezendes from California, USA, has started a funding campaign to have PCB data files recreated professionally from an Amiga 4000 mainboard, and publish these under open-source license. A couple of weeks ago the goal of 5000$ was reached, and meanwhile has even been exceeded.

A few days ago, Paul posted another update on his project page, now showing first screenshots of the actual PCB files that have been created. When done checking for errors, the files should probably be released to the public via the project's GitHub page around next week!

https://d2kw0licpa1moo.cloudfront.net/28730374_1527979674.9891_updates.jpg

Amazing stuff - becoming reality.

Here's Paul's GoFundMe campaign page, see there for more information and latest updates - and you can still make a donation:
