One of those rare occasions…

Did you ever had that feeling before? You find a box, you open it up and all the sudden, you feel like you are in a different time…

I had that feeling today – this “time capsule” arrived via DHL yesterday and I had found some moments to examine its content. The offer on eBay that I had been bidding on (and which I won) said nothing more than “Amstrad CPC6128 with Color Monitor and 75 Floppy Discs” – it cost me 100€ and yes, I am admitting it: it is a waste of money, there is nothing really useful I can do with the old computer, it is taking up space and it will catch dust…

Taking a second look, however, it is a key to an era gone by – not only has this computer and this generation of computers (at that time known as “Home Computer”) ceased to exist and has been replaced by standardized PCs – also, the games reflect the spirit of the time and in this special case, the three boxes the floppies came in reflect the personal taste of their owner (who’s name I have removed in the images).

However, it really was the content of the floppies that got me – yes, you can download an emulator for the CPC series for almost any current operating system, and you can even download huge game archives from the Internet that allow you to play those games on the emulator. But nothing – nothing! – comes even close to running it on the original computer with the original color monitor and the original 8bit sound (and the original flicker of the 50Hz cathode ray tube). Call me old-fashioned but emulation is just not the same as the real thing (just like a flight simulator can never ever make up for a real flight).

And there is one other point: while all those archives on the Internet will provide you with the “professional” software packages sold those days, it is very, very hard to get a hold of those ones written by amateurs: many computer magazines in those days existed because of and provided computer enthusiasts with pages over pages over pages of computer listings one would type into the own computer to get the program going. The attached sample, by the way, stretched over five pages and had a total of just over 300(!) lines of code. It turned out to be a Pac-Man-like game for free (or not more than the cost of the magazine).

Try it out: if you use Google to search for “smiley und die grumpies” nothing will come up. Those are the ones that will be lost when the last old tape cannot be replayed and last old disk cannot be read anymore. Are they important? Maybe not – but they are what many of us that started with computers when it was all new also started with.

<PersonalComment>

I recently wrote an eMail to the person who published a full-blown astronomy program called Sky***t in one of those magazines, asking if he might still have an old copy of the magazine or the code at hand. Sadly enough, I did not even receive an answer. I am sorry, I think, that…s*cks!

</PersonalComment>

Speaking of “many of us“: in the mid ’80s, several different companies had actively developed and maintained independent computer systems such as the famous Commodore C64 or the Amiga, the Atari 800XL and Atari ST Series or the Amstrad line (CPC 464/664/6128).

Although we had been fighting over which one was “the best”, none of them was so much different from the others – their hardware was different but the games and programs had often been available for multiple platforms. Likewise, the magazines their owners read had been different but the content was stunningly similar.

So let’s have a look at some of the games I found amongst those floppy disks I now own (and some that I raised for the emulator and included for one or the other reason in this post).

Bruce Lee – published in 1984 by US Gold. Jump & run through 19 levels, collecting items and fighting the Ninja and the Green Yamo.

I think, this one was one of my long-time favorites back then – the choice between homework and Bruce Lee was an easy one (not appreciated by parents or teachers but what’s new?)

Crazy Cars – published in 1988. Racing car simulator featuring a moving skyline (yes, it is New York – or at least I think I can see the Mrs. Liberty!) and other cars as opponents.

The trick here was to keep the car on track and avoid collisions while trying to outrace anyone else – does that sound so much different from F1 2010 or Need for Speed?

The Hobbit: this one drove me nuts – it was a text adventure based on Tolkin’s story and although the text parser today is considered “advanced for the time“, one had to have the proper key words included to make progress.

The Hobbit, however, was a commercial success story with over a million games sold by the end of the ’80s.

Hunt for Red October: who does not know Tom Clancy’s story about the Russian submarine commander taking his sub and crew to the United States?

Remember, this was the time the Cold War was hottest and the Soviet Union was considered “the enemy” (definitely here in Germany!) and this game gave us the chilling feeling of going to war with the Warsaw Pact. Amazing how times have changed since then…

You may be playing Prince of Persia today on Playstation or XBox – but this one, released in 1990 – was the very first version. Happy 20th anniversary, Prince!

Again, the graphics may be different but the idea behind the game is still the same! And that holds true also for the next game I found on the floppies – a very early version of a military shooter.

Today, we are playing Call of Duty or Medal of Honor – back in 1985 this was called Who dares wins.

I could go on for ages – there are so many games on those discs and there are so many memories attached to them – but I think, this post is already close to its maximum and therefore worth finishing up.

One last game to mention though: the mother of all submarine simulations: Silent Service. Published in 1988 by MicroProse, Silent Service has set the bar for any submarine simulation to come.

Long before Silent Hunter has come out, Silent Service already features a full map of the Pacific, Conning Tower and Periscope Views as well as Weapons management and Damage Reports.

It was one of the first games of a legendary game designer – Sid Meier. You may have never owned a C64, CPC or alike – but if you have every played a computer game, the chance is high that you know at least one of his games.

One last picture for the day – does this one look familiar? I wonder who said that menu bars and drop down menus had been developed by Microsoft or Apple…

Looking at the ZX-81 – does it work? Or is it dead?

Unfortunately, this turned out to be not as easy as I hoped it would be: the ZX-81 was built to “minimalistic” standards – to be polite! There is no LED or light to indicate if it is switched on or off, there is no sound one can test to see if it works… there is simply nothing but the picture on the TV Screen and – if you don’t have that – no other way to tell if the system is operational or not.

The problem with my ZX-81 is that the box did not contain the TV Connector cable. “Well, fine, I just use the antenna cable of my TV” was my first though and it quickly turned out to be naive: my cable does not fit into the connector of the ZX-81!

So here  I am, not knowing if the computer I bought even works, but curios as hell to learn if it does or not! I decided to “tweak” the connection to the TV a little but – putting a TV Antenna Splitter “the wrong way” into the connection between the computer, just to see if any sort of signal come out of the little black box.

And yes, it does: the TV produced a clear (but not stable) image of the ZX-81 Command Prompt on UHF Channel 36 – so now that I know it does actually work, I can start wondering about how to hook it up to either the TV or – preferably – a modern LCD Monitor.

Another Home Computer Veteran

Besides the CPC464 that has been described in some of the previous blog posts, I also managed to get hold of an Sinclair ZX-81 via eBay. This one came at 54,50€ plus shipping.

The box arrived today and – you may imagine – I opened it fairly soon after the mail man had handed it over. At first glance, the ZX-81 is in a pretty good shape. I have not been able to attach it to any TV or monitor yet but the outer inspection makes me hope that this one will work as advertised.

An Autumn Beef Stew

Guests in the House

There will be guests tomorrow and I need something to serve – something to match the time of the year, can be prepared with fresh ingredients and can cook today and be served tomorrow. My choice: an Autumn Beef Stew.

Credits

This one is inspired by a beef stew I have seen in a Jamie Oliver book – it looked great, sounded tasty and sure enough a stew is easy to make and can be served the next day. As always, what I had seen in the book served as “inspiration” but I made my own changes to it – namely, I like my stew with either home-made Spätzle or dumplings on the side so I remove anything that would not go with that (such as potatoes in the stew, etc.)

What you need

I quickly stopped by the local grocery shop this morning to pick up the following (preferably fresh, not the supermarket stuff):

  • about 1000g beef, suitable for a stew (that is a lot of meat, if you like it less meaty than I do, take about 800g)
  • Garlic, 2 onions, 2 parsnips, 4 carrots and a butternut pumpkin
  • a can of peeled tomatoes
  • a bottle of red wine
  • 1/2 Liter of Beef Stock
  • Sage leaves and rosemary
  • Olive oil, butter, flour to dust the meat

Preparations

Pre-heat your oven to 160°C. Peel the onions and cut them to small pieces – don’t cry! Then peel the carrots, half them and chop them into thin slices. Repeat the procedure with the parsnips. Now, take the pumpkin and cut one half into dices – about 1cm to half an inch. Put everything on the side.

If you have been clever (or nice to the butcher) your meat is already diced properly – if not (like mine), cut the meat into pieces of about 2cm so one can easily eat them without cutting. When done, dust the meat with flour and put it to the other prepared bits.

The Cooking

You now need an appropriate pot – one that can go onto the oven first and then into the oven later! And it needs to be big enough for the stew.

Put it on the oven and add just enough butter and olive oil to cover the base. When the butter is is molten, add the sage leaves and the onions – cook till the onions start to get glassy.

Now add the meat and stir. Wait for the meat to gain some color and develop some flavor. Then add the remaining ingredients – parsnips, carrots, the pumpkin and the tomatoes. When everything is properly mixed, add the wine and the beef stock – you need enough liquid to make sure all of the bits and pieces can actually cook in it. Finally, season with freshly ground pepper and salt as needed and let it cook – I have it sit in the oven for three hours at 160°. You need to try it from time to time – it is done when you think it is done – meaning when you think the meat is soft enough and all the other things as well…

The good thing here is: it would not mind staying in the oven another hours, so your family or guests do not really have to rush to the point for you to serve them.

Serving

Before serving, cut the rosemary and the garlic into fine pieces and mix them – sprinkle over the plates when serving. It just smells great and tastes even better! Enjoy…

Bringing the DDI-1 Floppy Drive back to life

With the CPC 464 cleaned up and still working, I took the external Floppy Drive off the shelf (yes, ebay as well! – 43,60€, it seems to be pretty rare…) and connected it to the CPC. All switches on, all lights green…

…but the typical Disk-Drive Extensions to the instruction set are not present. Hm… my first guess: either the contacts on the mother board are more eroded than they look or the connector in the connector pack is a bit weak. After a couple of disconnects / reconnects, the drive is now recognized but it is still an area to look into later.

So, time to load a disk (also eBay, two disks for 0.99 Brisith Pounds) and switching to the drive (I remember the syntax: |a) and yes, there it is… but trying to read anything from the disk only results an error: Disc missing… more “hm’s”…

So I peeked and poked the Internet a little bit, and it turns out that the DDI-1 Floppy Drive has a weakness – at least these days, some 25+ years after production: the drive belt that is transferring the power from the motor to the spinwheel turing the disc tends to wear out and often requires replacement.

A friend in the office had old drive belts for cassette players at hand so I opened up the DDI-1 Floppy today and replaced the belt.

Caution: you are working on an electrical device that is connected to 220V Power – unplug the device first and do not touch the transfomer area in the back – not even after you unplugged the device!

Now, turn the DDI-1 upside-down, then unscrew the two large screws on the bottom as well as the four screws on the left and right side of the drive. Turn it back into an upright position and carefully lift the top cover.

Next, detach the cables connecting the actual drive with the lower board in the case – there are two connectors that can be simply released and one grounding wire that needs to be unscrewed. Lift the drive unit out of the case and turn it on its side.

Then remove the four screws holding the lower board in place. Keep the drive on the side to avoid and pieces falling from it! You may want to detach the connector going to the front of that board to gain better access to the area of interest.

You can now see the drive belt. Remove it and replace it with a matching one. If you cannot find an exact match, try one that is slightly smaller.

When done, re-assemble the device and put everything back in place. You may now plug the drive back into the power outlet. Switch on the drive and ensure that the lights are on. Then switch on the CPC464, put in a disk and try again – my drive is now working just fine (so I can continue bidding on eBay on additionan disks – they are rare 3″ Discs not produced anymore so eBay is the only chance to get them (as far as I know))
