Sony MPF520-1/04 PC FDD to Amiga conversion

The external floppy drive that I was using with my CDTV died and replacements were a little expensive (ok, they weren’t that bad but I was impatient).  So I figured, how different could an Amiga FDD be from a PC one?

Turns out there are a couple of differences, the signals on pin 2 and pin 34 are reversed (Density Select, Ready Change) and the drive needs to identify as DS0 if it’s the internal drive on a normal Amiga or the external drive on the CDTV (PC drives don’t because they’re generally picked up using cable select).

How this works will vary depending on your drive, but for my Sony model it was very simple.  It requires two wires, two track cuts and a jumper change.

Basically we need to cut the connection that pins 2 and 34 are on, and then put a wire from 2 to a solder point that was pin 34‘s original destination and between 34 and a solder point that was pin 2‘s original destination.

You should be able to work out where they are from the pictures, be careful when cutting to only cut the one track and don’t cut yourself.

If you want to revert the drive you can just run a wire between the pins and their original solder points.

The jumper is at the back of the drive, next to the motor.  If it’s on 0 and 1 (nearest the motor) then it’s set to be DS0, if it’s on 1 and 2 then it’s DS1.  If you want it to be internal on an Amiga or external on a CDTV then it needs to be DS0, if you want it external on an Amiga then set it to DS1.

The Vectrex is an interesting beast.  It was created with the idea of portability in mind, the idea that the owner could pack it up and carry it wherever they wanted then plug it in and play.

To this end it had a lovely Vector based display.  Unlike the raster based displays that televisions employed, the vector display was designed to draw lines.  The result is an image that, whilst only black and white, pops off the screen and has a fair 3D effect.

Western Technologies shopped this idea around to manufacturers and eventually signed a license agreement with General Consumer ElectronicsGCE would build and distribute it and pay WT royalties.

GCE showed it off at the Consumer Electronics Show in 1982 and released it in November of the same year, just in time for Christmas.  The initial sales were promising, so much so that Milton Bradley, who had been looking to break into the games market, decided to purchase GCE.

With the extra muscle that the large toy company bought, the Vectrex was marketed in Europe and, in a partnership with Bandai, Japan.

However, the promising start ended when the video game crash, which affected North America and parts of Europe, hit.  The Vectrex sales disappeared and MB lost millions of dollars, causing them to merge with Hasbro.

Because the Vectrex was a black and white device, and the built-in screen meant it always would be, games came with a colour overlay.  This overlay marked off certain parts of the screen and highlighted score areas.

The downside of this technique is that over time the display becomes misaligned, so the overlays no longer line up properly.

The Vectrex produces a loud buzzing during operation, due to a noise issues with the high voltage line.  There is a mod that can be made to reduce this.

The Vectrex was the first home console to offer a 3D peripheral, the 3D Imager, which used a spinning disc to alternate eye covers.  The Vectrex also had a light pen which could be used by a couple of titles.

The Vectrex was a phenomenal achievement for it’s time and still has a devoted fan following.  The screen is hard to describe and can’t be adequately reproduced in pictures and video.

All Vectrex units come with Mine Storm, an asteroids clone, built-in.  It loads when a game cartridge is not detected.

Nintendo didn’t rush their second console, despite their main competitor, Sega, releasing the first of the 16 bit consoles, they continued development for another two years.

The result was a sleek and powerful console with a great set of launch games.  Nintendo didn’t have the luxury of exclusivity this time around but it didn’t matter.  Publishers wanted to release games on the undisputed winner of the previous generations new machine.

The Super Famicom was a console that had been designed by games developers and players.  Nintendo had talked to it’s in-house teams and specially chosen external companies, like Rare, to find out what they expected in the next generation platform.

The Super Famicom released in Japan to pretty much instant success.  The console sold so well that Nintendo were forced to ship them at night to stop organised groups from stealing them.  Whilst they quickly caught up with Sega in their home territory they didn’t have the same lead they’d had before.

The battle was even closer in North America and Europe when the console was released as the Super Nintendo Entertainment System (shortened to Super Nintendo or Snes).   However, although it was popular in South America, most of it remained a Sega stronghold, especially Brazil.

Although most of the world had a console that looked like the Japanese Famicom, the North American model was more boxy and had a curious bulge around the cartridge.  The rumoured reason is that a lot of the failed NES consoles were damaged by things being spilt inside when they were balanced on top, so the console was given less space at the top for this to happen.

The resultant polarity amongst owners saw the first Fanboy wars of the console world.  In the previous generation Nintendo had been so dominant that they were largely the only console anyone talked about, but now the playgrounds were split between Nintendo and Sega.

The Super Nintendo was, on paper, a far more sophisticated machine than the Megadrive.  The Megadrive managed to compete because the Motorola 68000 was still a very powerful chip, and generally faster at most tasks.

The Super Famicom did win the generation, but it was a hard battle.  Sega had shown that Nintendo were vulnerable and they were still two years ahead in console development.  But Nintendo had proven that they did not get intimidated by competition and had produced a genuinely classic console.

Sony took over the console world with their first console, the Playstation.  They had no experience in the market but still managed to outgun Nintendo and Sega.

Needless to say, the industry was looking forward to seeing how they coped with their second foray into the gaming world.  They did not disappoint.

The Playstation 2 was a behemoth in terms of technology, it shipped with a, then, expensive DVD drive.  It had a processor that was designed from the ground up to play games.  It was capable (at launch) of installing Linux, so it could be used as a powerful workstation.

The PS2 was an instant success, true the software attach rate wasn’t great.  Whilst it wasn’t cheap the PS2 was still far cheaper than any DVD player, so many people bought it for that purpose.  This may not have sold games but it put a PS2 in a lot of living rooms.

The rumour is that this fact was the final push the execs at Microsoft needed to fully support the XBox project.  The idea that a company as large as Sony, who seemed to be supporting an alternate operating system to their Windows platform, would control the living room was too much of a risk.

The Playstation 2 was definitely responsible for the very fast acceptance of DVD, it quickly became the single most used DVD player in Japan and probably the world.

The Playstation 2 saw the first 3D version of the Grand Theft Auto franchise.  The franchise is now one of the highest grossing entertainment products of all time.

Sony released a price cut slimline version of the Playstation 2, called the Slim.

 

The Playstation 2 is considered to be one of the greatest consoles ever made and is the longest lived and highest selling.  It was a genuine display of the art of technology creation and cemented Sony’s role in the gaming world.

Nintendo had released a floppy drive for their previous console, the Famicom.  After they released it’s follow up, the Super Famicom, they decided they wanted to do the same thing.

Rather than approach Sharp as they had with the Famicom, Nintendo decided to talk to Sony through Ken Kutaragi, the man who had convinced them to use the Sony SPC-700 sound chip instead of the near standard Yamaha family.

Sony returned with a prototype, a unit that was slightly bigger than the base machine but packed a CD Rom.  This was a working prototype and the Nintendo execs agreed to work together.

Nintendo agreed to announce the partnership at the May 1991 Consumer Electronics Show.  However, behind the scenes then president Hiroshi Yamauchi had re-read the contract and realised it handed Sony far too much power.

When Nintendo of America chairman, Howard Lincoln, stepped up on the stage instead of announcing the partnership with Sony, he announced one with PhilipsPhilips were Sony’s main rival in the CD world and this was a  gut punch too far.

Sony approached Sega, Nintendo’s chief rival, and offered them the technology.  Sega of America were interested but the idea was vetoed by Sega of Japan who stated, Sony don’t know how to make hardware or software, why would we do this?

Sony considered canning the whole project but instead decided to do it themselves after all.  They started planning a whole new machine based on their work and, after seeing Virtua Fighter, making it primarily 3D Focused.

The launch was nearly perfect.  Because they didn’t have the luxury of an existing games unit, they purchased companies and signed exclusivity contracts with others.  Sega managed to help them by flubbing the Saturn launch badly and Nintendo were far behind with their 3D console.

The Playstation shot into the lead in every market, far outselling the Saturn.  It was still being outsold by the previous generation but price cuts in the following years solved that too.

Whilst Nintendo are considered to have saved the games industry with the Famicom, they didn’t really grow the market in any meaningful way.  The Playstation, on the other hand, increased the target market to an older generation, thus hitting a more mature and wealthier demographic.

Because of this the games market started on the path to beating the film industry in revenue and moved the hobby out of the niche that it had been stuck in since inception.  They made it cool to play games.

The Japanese market took longer for Sony to dominate, whilst they took the lead early, the Saturn didn’t fall as far behind.  Much of this was due to brand loyalty, something that the North American and European markets weren’t really affected by.

Sony released a cut price, smaller version called the Ps One in 2000.

The development of the Saturn was tumultuous.  Sega had tried to extend the life time of the Megadrive for as long as possible by adding new peripherals such as the Mega CD and 32X.  But this had caused confusion amongst the consumers and they started to panic.

The Saturn itself had gone through numerous design changes, initially it had been designed as a 2D machine, Sega hadn’t expected 3D to be a key selling point, considering it was barely taking off in the PC world.

But Sony had made it a key feature of the upcoming Playstation and whilst Sega didn’t consider Sony to be their primary competitor enough buzz in the media finally got though to the heads in Sega Japan to make them realise they had to react.

The redesigned Saturn was based on Sega’s existing Model 1 architecture, itself a groundbreaking 3D arcade system.  The architecture used the SH2 RISC Processor, a custom chip designed by Sega and Hitachi.  Whilst not a GPU in the sense we know it now, the chips made certain calculations faster.

For 3D to work it needed two of these chips and therefore so did the Saturn.  After Sony released the specs of the upcoming Playstation Sega were forced to add another chip, the VDP, to compete.

Whilst this was happening Sega of America were trying to draft their own system, this would use a custom chip created by SGI.  But Sega of Japan were uninterested in changing their plans and were largely dismissive of the team SGI sent to talk to them.

This cold-shoulder approach caused SGI to end their talks and they instead sold the solution to Nintendo and it became the basis of the Nintendo 64‘s Reality Processor.

In the end the Saturn became an 8 chip megalith.  The complexity was astounding and Sega were struggling to work with it internally just to create the tools that developers would need to make games.

At this point Sega decided to make the 32X add-on for the Megadrive.  This had some elements from the Saturn, including the Hitachi SH2’s.  But it would not be compatible with Saturn software and consumers were confused by the mixed messages they were getting.

The Saturn released in Japan to fairly positive sales.  Virtua Fighter pretty much sold the system and almost everyone buying a console bought it.

But in a move that would haunt Sega until they left the console market, they announced the North American release date of Saturday the 2nd of September 1995.  Nicknamed Saturnday this day was chosen to give western developers time to get to grips with the complex system and for retailers to prepare for stock.

But then, at the E3 event in May the head of Sega of America, Tom Kalinske, announced that the console would release immediately at a price of $399.  Even worse only a few retailers had stock, the rest would miss out of the traditionally high demand first day.

This news upset publishers and retailers.  The publishers had to rush development of their titles to get them ready, and most would miss release day by weeks.  The retailers who had not received stock were outraged, some announcing that they would never stock a Sega item ever again.

This was an almost perfect outcome for Sony, who were not frightened into moving their release date earlier, instead the head of Sony US came out and said one thing, $299, the price of the Playstation, before leaving the stage to universal applause.

Once developers had got used to the Saturn hardware they found out it was a powerful beast, but it was missing a few things that the Playstation had.  But it also didn’t suffer from the texture warping effect that Sony’s machine did.

The Saturn wasn’t a flop, as such.  It sold well enough, but it caused tremors in the industry that Sega never recovered from and had a large impact on the failure of their next system, the Dreamcast.

There are two conflicting accounts to how the date move happened, Sega of America said they were unaware of the date change until the day of the conference when Sega of Japan ordered them to announce it.

Sega of Japan say that SOA were well aware beforehand and were involved in the decision.

We may never know the absolute truth, but the fact remains that 3 retailers already had stock and an agreement to sell them the same day, that was not something that Sega of Japan could arrange and was definitely not something that could be arranged in a couple of hours.

Atari were hit hard in the video game crash and were eventually sold off a couple of time.  They mostly concentrated on the computer market but still attempted to regain the glory they’d felt with the 2600.  The 7800 followed the largely failed 5200.

The 7800 was basically an expanded 2600.  It featured the same audio chip but a vastly improved graphics system.  It was the first console developed outside of Atari, instead designed by General Computer Corporation.

The 7800 was an improvement over the 2600 and 5200, but not enough to compete with the incoming Japanese consoles.

The 7800 is compatible with the 5200 and 2600 range of games.
