NEW Item!

Best Electronics Compact Flash Upgrade Kit for the Atari Falcon 030 Computer.


Best has been hearing from some Falcons hackers for some time now, who have adapted Compact Flash (CF) storage cards with a modified adapter card for use with the Atari Falcon to replace the Internal IDE Falcon Hard Drives.

Why use Compact Flash storage technology on the Atari Falcon?

  1. Now with Compact Flash storage cards technology is maturing and are now being mass-produced, CF storage cards prices have dropped in recent years.

  2. Solid State (no moving parts) fast electronic storage of your Falcon data Vs a Mechanical spinning Internal Hard Drive mech, which as we all know, all Hard Drive Mechs will wear out (with so many hours of use) or just outright fail on you.  Have you ever heard of a Compact Flash Storage card failing?

  3. With a Falcon compact Flash upgrade kit installed inside your Falcon 030, you will find your Falcon making one less Internal Hard Drive noise.  Now you will only hear the occasional internal Floppy sounds and the internal Falcon cooling fan only!

  4. The Best Falcon CF upgrade board mounts to the existing Atari Falcon Internal Hard Drive bracket, no other new hardware required.

  5. Generally in most cases (depends on the Atari Falcon formatting software and Compact Flash card) you will find faster file access speeds and shorter file read and write cycles.  Best Installs either the 1993 Atari Falcon HDX Hard Drive boot up program or the  State of the Art very Fast HDDriver Falcon Boot up program on each Compact Flash memory card included with each Falcon Compact Flash upgrade Kit.

  6. Extends the life of the Falcon Internal Power supply.   A CF Card Draws a lot less power / amps off the Falcon Internal Power supply compared to a older Power Hungry spinning IDE hard drive mechs.

Sam C. of TX.  By Sam's low Best Customer number, we can tell he has been a Best Electronics Atari customer for over 20+ years now.  He recently placed back to back Atari orders.  On his second Atari order, Sam ordered the Best Falcon Compact Flash 2 GB upgrade for his Atari Falcon.  Placing his third Atari order in a row with Best he said:  "The Best Electronic Compact Flash upgrade is phenomenal. I regret waiting so long before acquiring one. It was an effortless installation thanks in part to the included printed, very detailed instructions and accompanying photos.  Those are what made it “fool-proof” for me. Great job!  Bravo!!!"

Dimitrios B. of Greece   "I receive yesterday my  Falcon 2 GB Falcon Compact Flash Upgrade Kit

"Im very happy with my 2 GB Falcon Compact Flash Upgrade Kit!!!  Excellent quality and the best documentation ever seen!!!! Thank you!"

Edward B. of IN   By Edwards low Best Customer number, we can tell he has been a Best Atari customer for over 20+ years now.  Edward ordered one of Bests Falcon Compact Flash (Solid state replacement for the Falcon internal 2 1/2 inch mechanical Hard Drive mech.) upgrades kits.  "Just wanted to say that installed my CF upgrade for my Falcon. It is wonderful and works like a charm. I cannot believe the speed in the boot process. Now all I have to do is setup the boot partition. Thanks much for this and thanks much for the very fast service. I did not expect the upgrade to arrive in just two days time. You guys are awesome.  Thanks again"

  1. A Compact Flash Falcon storage Upgrade draws less current (less strain on the internal Falcon Power supply) Vs an internal Hard drive mech.  Compact Flash cards do not generate as much internal heat compared to an always spinning / running Internal IDE Falcon Hard Drive mech.

  2. Best Electronics Falcon Compact Flash Upgrade Kit has been Tested and Engineered to be easy to install and once installed, maintenance free.  In most cases if you can change a tire or battery on a car and have a Phillips screwdriver, you can install a Falcon Compact Flash upgrade Kit inside your Falcon 030 Computer.  A solder less, plug in upgrade.

  3. The Best Electronics Falcon 030 Compact Flash Upgrade Kit comes with a 2 GB Compact Flashcard (2 large Falcon partitions installed and we can custom set up any more numbers of Falcon smaller partitions you request at time of purchase), Compared to the stock original Atari Falcon 030  80 MB Internal IDE Hard Drive, the 2 GB Compact Flash card is a 25X increase in storage capacity for your Atari Falcon.  The Average Atari Falcon user will probably never use all of this new storage capacity up!  Larger CF Cards like a 4 GB version will have 4 partitions or more installed.  The default Max Falcon Hard Drive / Compact Flash partition size is 1 GB or less.

  4. With Compact Flash Cards getting larger in GB size and prices dropping, all you have to do to upgrade your Best Electronics 2 GB Compact Flash Falcon in the future is unplug the 2 GB Compact Flash card and Atari Falcon format the new larger Compact Flash Card slide in card.

  5. The Best CF Falcon adapter board will accept Type 1 and Type 2 CF memory cards and also the SDHC, miniSD, microSD, and RSMMC with a CF type 2 adapter / conversion card (CF card size adapter card with slots for the other version / standards of micro memory storage cards above).

  6. Best Electronics has done all of the prep work on the setting up the CF memory card for use with the Atari Falcon 030 computer.  It can take an average of 1 to 3 ˝+ hours alone to Falcon Format and Sector scan a new CF memory card depending on the size of the CF card.  So when you get your Best Electronics CF Falcon drive, it has been Falcon formatted and is Lock and Load ready to drop into your Falcon and boot up from day one.

Stian E. of Norway  "I can really see overall performance improvement after installing both the CF and RTC chip."  Best's Atari Falcon 2 GB Compact Flash adapter and new replacement Falcon Clock module

Recently Best was informed by the programmer of the HDDriver Atari Hard Drive prep program we could no longer install the HDDriver fast boot up file only (similar to the Atari 8 bit DOS boot up file) on any of the Best Falcon Compact Falcon upgrades.  So Best has opted to now put out two versions of the Best Falcon Compact Flash upgrades.  The 1st version uses the older / slower booting up Atari Falcon 1993 HDX Hard drive boot up program.   This Atari programmed Falcon Hard Drive boot up program has not been updated since 1993 with newer features (like newer Hard Drive mechs) and is no longer supported by Atari.

The second Best Falcon CF upgrade version, includes the faster boot HDDriver software and is supplied with the current version HDDriver software Install disk.   You will become a registered owner of the HDDriver software and entitled to any future HDDriver software updates free over the Internet.  This HDDriver Hard Drive software has gone thru constant Software Upgrades / Updates since 2018 to present day.

If you are on a budget, do not plan to do any Falcon upgrades and do not care how fast your Atari Falcon boots up.  Go with the older Atari HDX version Best CF upgrades.

If you want the fastest Falcon boot up sequence, then go with the HDDriver Best Compact Flash upgrades.

The Best Electronics Falcon Compact Flash upgrade Kits comes with a Compact Flash adapter card modified for the Atari Falcon, 2 or 4 GB Compact Flash card installed.  The Falcon CF upgrade Kit comes with a well-documented 11 page installation manual with pictures and step by step instructions for the novice installer or Falcon expert.

Read the 5+ month story behind the 2nd Generation "TT" Touch Keyboard upgrade internal contacts and how they almost did not happen.


Karoly B. of Germany.  "A while back, I ordered 3 TT Touch sets from you. They arrived fine and all work great in my ST, STE, and a Falcon.  As a satisfied customer, now I'm back, ordering more Atari things from your shop."  This Atari order Karoly ordered 1, 2nd Gen. Best TT Touch ST / STE / Falcon keyboard internal upgraded contacts and 2, 2nd Gen. Best XE Touch XE / XEGS internal keyboard upgrade contacts.  It is extremely rare to get any Atari feed back comments from any of our German Atari users.  In the last 40+ years in the Atari business, this may be our 9th or 10th feed back comment from Germany !


Erhard P. of Germany   It is extremely rare to get an Atari German user feed back comment an any of Best Atari products.  Over the last 39+ years in the Atari Business, we have had a total of 8 German Atari comments back.  Erhard ordered a set of Best ST / Falcon Keyboard TT Touch internal Silicon upgrade contacts.  "I immediately opened one of my ugly-touch-keyboards and replaced the greenish silicone things with the new ones from BEST and reassembled the keyboard.  I must say that I got more than I had expected: pushing the keyboard keys now requires a bit more pressure, but I am extremely happy with that pushing-point-feedback" (Tactical bounce / feed  back when the ST key cap is pushed down and released). "In addition the computer now recognizes every key press which was not the case before"  Old worn out / bad ST / Falcon keyboard Silicon dome contact conductive internal dot contacts.


Asan T. of the UK  Asan must of read a review on the Best exclusive TT Touch internal ST - Falcon keyboard upgrade Silicon cups.  He ordered 3 set of them.  "Just to let you know that these have arrived safely here and I've just fitted them.  Oh my goodness, these are absolutely amazing! They completely transform the feel of the keyboard and my only regret is that I didn't experience the benefit of these 30 years ago!  Thank you so much and best wishes"


Anders G. of Sweden   Anders ordered some new Atari TT Custom replacement chips and the Best Exclusive TT Touch internal keyboard  Silicon replacement upgrade / enhancement contacts for Atari ST / STE / Falcon computers.  "I just wanted to write and thank you for the TT-Touch keyboard upgrade!

Garry T. of OH  Garry ordered one of Bests "TT Touch" Internal upgrade Silicon contacts for the Atari 520ST / 1040STF / 1040STE / Falcon keyboards.  "The Best TT Touch keyboard silicon replacements work great.  Much nicer feel when typing on my 1040 ST.  Super easy to install."

Follow up Comment: "After years of mushy typing on my 1040ST, I discovered the Best TT Touch keyboard silicon replacements.  I was a bit nervous about opening up my ST as I am not technical, but the instructions were super clear and the whole replacement process only took about 10-15 minutes and only required a screwdriver.  Now I have a super responsive keyboard, it's like having a new ST again!  Thanks Best!"

Stuart D. of Australia  Stuart ordered Bests, TT Touch keyboard upgrade contacts, Falcon Translucent Dust cover and Best Rev. 10 all Atari Catalog.  "I have received the order.  TT upgrade is fantastic, thanks!  The catalog is also a great read."

Follow up Comment:  "I have to say that over the years I thought I'd forgotten how to touch type.  With the TT Upgrade, no spell check, no autocorrect (and a little bit of practice) I'll be back to 75WPM quite quickly!  Much better than any keyboard I can buy today!"

Richard K. of the UK  Richard has placed 2 back to back International Atari orders with Best.  He is ready to place his 3rd Atari order.  "I fitted your Best TT touch Falcon Keyboard Upgrade contacts to my Atari Falcon - what a fantastic transformation!!  In fact so good I'd like to purchase two more kits for my Atari ST's." 

Matt M. of WA  On placing his 3rd in a row Atari order for the month of May with Best Electronics, Matt wanted to order the Mega Touch ST Keyboard Key Cap springs that stiffen up the mushy ST keyboard key caps.  Best recommended that he would be much better off getting the Best TT Touch 1040STE Keyboard internal Silicon upgrade cups.  "Installed those rubber cups on my STE’s keyboard this morning — BIG improvement! Thanks!"

Brian R. of KS  "Got the TT-touch installed yesterday and they work wonderfully!!"

Jason F. of UT  Jason purchased Best Electronics TT Touch internal silicon cups that upgrade Atari 520ST, 520STFM, 1040ST, 1040STE and Falcon Atari Computer Keyboards.  The easy to install TT Touch product will remove the ST / Falcon Mushy Key caps and end up with a high grade tactical feedback PC feeling Atari ST keyboard  "I have to say the TT Touch I installed into my Falcon is premium work, I can tolerate typing on it now!

Atari 520ST, 1040ST, Mega 1/2/4, Stacy, 1040STE, MegaSTE, TT and Falcon Computer Diagnostic Loop Test Hardware Test Kit 

When Atari set up a new US Atari ST Service Center Dealer, as part of the ST Dealer Service Center package (full set of ST Computer repair Manuals, ST Color and Monochrome Monitor manuals, 520ST/1040ST Diagnostic Cartridge), a new complete 520ST, (later) 520STFM and 1040ST Computers for parts) and this loop back ST Test kit.  The new Atari ST Dealer paid for ($,$$$+) for this complete Atari Service Center Hardware Package.  

This Atari ST Loop back test hardware is used with the many different Atari ST different Diagnostic Cartridges (520ST/1040ST/Mega, Stacy, 1040STE, MegaSTE, TT or Falcon Diagnostic Cartridges) to fully test all ST computer Internal and External hardware functions.  Extra port shorting hardware / plugs required for the 1040STE, MegaSTE, TT and Falcon computers to full run all of the extra Diagnostic Tests / Ports (extra features or different style ports of those model Atari computers). 

The two DB-9 black Joystick cables are connected up to the ST Joystick/Mouse ports and back to the Loopback green PCB (most ST computers require you to crisis cross (not one to one) these DB-9 shorting cables back to the loop back PCB to get the proper port diagnostic results).  The short black or gray DB-25 Parallel cable is connected to the ST printer port and loop backboard.  The short gray ST DB-19 DMA cable is connected to the ST DMA port and the loop backboard.  The 5 pin Din shorting cable is connected up to both ST Midi Ports (one end of this Midi cable has a Red LED molded into the translucent connector housing to see the Diagnostic Midi Send and Receive sent signals).  The DB-25 Serial port shorting connector is connected to the ST Modem / RS232 external Port.

Depending on the exact version Atari ST Diagnostic Cartridge used with the ST loop back hardware test board, you can choose from the ST Diagnostic display menu to run between different ST Diagnostic tests one at a time or our 27+ year Atari Super Tech’s standard 12 to 24+ hour continues Burn in loop that he tests all ST computers with.  Typical Atari ST Diagnostic tests you can run using the different Atari ST Diagnostic Cartridges and Loop back external Hardware, upon boot up displays ST TOS Rev., Total ST / TT Fast Ram, Keyboard I.C. Rev. level., 5 ST Ram Tests, 7 ST internal Chip set timing Tests, if present 14 Blitter chip tests, if present 2 Real Time Clock tests, Audio tests, OS ROM Test, 2 Printer Port I/O Tests, Color and Monochrome ST display tests, 3 Keyboard tests, 5 Mouse and Joystick port tests, 12 RS232 / Serial / Modem I/O port tests, 50 / 60 Hz display toggle, 17 Internal or External Floppy Disk Drives tests, 4 DMA I/O port Tests, 2 Parallel port I/O tests, 5 Midi Send and Receive Tests.  The best way to fully test and burn in any unknown condition or repaired Atari ST computer.

Atari Tech Tip on the Loopback ST PCB board.  Our Atari Super Tech strongly recommends you tape the anti Static pink bubble bag the Loopback board comes in (or tape a piece of thick and oversized piece of cardboard) to the exposed back side / solder side of the Loopback PCB board, to prevent it from shorting out / damaging the different I.C.’s on the top side of Loop back PCB should the back side of the exposed PCB come in contact with any metal.
