Atari 8 Bit Disk Drives and SIO Cables
Pete R. of IL Pete contacted Best via E-Mail. He had a second old Atari 810 Disk drive he wanted to get going again. Several E-Mails back and forth, Atari 810 diagnostic questions asked and answered, things tested, picture received. "IT WORKS! Best has been the BEST site for Atari products I have seen. I had not purchased anything from them previously. I had an 810 disk drive that had the more recent upgrades. My problem was I wanted an original 810 disk drive working. The Stepper motor was not functioning. I contacted Best with my issue and after a few emails, they recommended a replacement side board. It worked Perfectly! They know what they are doing!"
Best Atari 810 Tech Tip: Atari 810 problems fall into a few different basic reasons / problems. A dead (no LED or LED's works but no mechanical movement) 810 is usually a bad rear Atari 810 Power board. It could also be a combo of both a bad rear power board and sideboard problems. A mechanically working 810 disk drives that have Read (boot errors) or Write (can not format a SSSD 5 1/4 Floppy disk, which is one of the true tests of the health of any Atari 810 or Atari 1050 Disk drive) problems is usually a 810 5 1/4 Disk Drive mech. problem. But could also be a combination of both a bad 810 disk drive mech. and bad 810 sideboard problems. Early made Atari 810 Disk drives had two known major problems. On early production runs of the 810 sideboards, they did not have the 810 Data separator board plug in upgrade daughter board (the WD 1771 disk controller chip plugged directly into the side board). The second known problem was the single rear 810 power board. Both were known to cause all kinds of problems with early Atari 810 disk drives and the only way to fix them was to add the 810 Data separator board and install the 810 improved rear power board. The Atari 810 disk drives without the Data separator board had all kinds of Read and Write 810 Head problems. The single 810 rear power boards had all kinds of speed problems that seem to change all of the time without making any kind of speed adjustments on the single rear 810 power board. Both known 810 problems we latter fixed in the Atari 810 production run with a new plug in 810 Data Separator board (which cured most of the 810 Read and Write electronic data problems). The second Atari 810 Major problem was cured with what is known within Atari Engineering as the Atari 810 Grass Valley board set below (where in California it was designed). This Atari Engineering Grass Valley 810 new board set cured all of the Atari 810 speed problems. It consisted of a new redesigned / improved replacement 810 rear power board and a second daughter board (sat over the 810 Disk Drive mech. and was connected to the rear 810 board with a 10 pin wire harness and to the 810 Head wire harness). The second Grass Valley 810 daughter board helped to separate and boost the Atari 810 disk drive Head signals. Also the Atari 810 Disk Drives that used the Tandon 5 1/4 internal Disk Drive mechs, had a very high failure rate of the Tandon access front Lift door (like a garage door opening) white pivot pens breaking. The second Gen. improved Tandon 810 lift door assemblies in stock.

Michael W. of CA Michael contacted Best via E-Mail, because his old Atari 810 disk drive would read and load some Atari disk based games, but refused to properly format Atari floppy disks. He was think of getting a New Atari 810 sideboard with data separator and a C version (last 810 revision ROM made) 810 upgrade ROM to fix his 810 format problem. Several 810 diagnostic E-Mails questions back and forth, pictures sent and received. Best told Michael his Atari 810 already had a 810 sideboard with the 810 data data separator and in most cases that was not his 810 format problem. We recommend he should get a new upgrade Atari 810 Grass Valley Rear power board and top head card, to replace the old 810 single rear power board with known 810 Speed problems. "Just wanted to say "thank you!" - the Grass Valley board got my 810 working again - what would I do without your great support and stock / supplies of retro parts! Thanks again"
Guillermo G. of FL Guillermo was trying to repair an ailing old Atari 810 Disk drive. Best sent Guillermo a new drop in replacement 810 complete side board, but it did not seem to get the 810 going again. Several different E-Mails back and forth, Atari 810 diagnostic questions asked and 810 information back and forth to Guillermo. "Proceeded to re-seat all the connectors & the unit is working great. Thank you for all your help & believe me you are a life saver! Now need to get my A410 fixed! Can't wait for my next shipment of goodies to arrive! Thank you greatly with this & all the problems that I have had in the past. You have a customer for life! Much appreciated!" This is Guillermo second customer feed back comment to Best.

Atari 1050 Disk Drive Includes U.S. 50 watt 110 Volt Power Supply, 3 foot / I/O Cable and 1050 US Owners manual with DOS 2.5 Disk. Each Best Reconditioned Atari 1050 has passed all the Atari Field Service 1050 Diagnostic disk tests including the 3+ hour burn in test. This Atari burn in test is so long and fully tests all of the Atari 1050 Read / Write functions and heats up up all of the 1050 chips / power circuit. On an old / marginal / going bad 1050's will fail on this very long test and show up on the final Diagnostic Atari 820 printer print out results. Best has found over the years this long Atari 1050 3+ hour burn in test, we have to use a very high quality New virgin DSDD disk and only run once on the new high quality disk. This very long burn test will literally wear out early / 1st Gen. Atari new poor quality SSSD disks and give you false Diagnostic printout results. Over the years, Best has even had New in the box Atari 1050 disk drives fail his very long burn in test. For sure this long burn in Atari 1050 burn in Diagnostic test was never preformed on new Atari factory made 1950 Disk Drives during the assembly process, it simply takes to long. Comes with the Normal 90 day Atari Warranty. No Atari 1050 box, no foam shells See above pictures. |

You are an Atari 8 bit computer owner and have just about every Atari 400 / 800 / 1200XL / 65XE / 130XE and XE Game system peripheral SIO port plug in product made. But on both versions of the Atari 410’s / XC11 / XC12 cassette recorders, XM301 / SX212 Modems / Atari Direct connect printer cables, any other Atari peripherals with a single SIO connector in port and any future made Atari peripheral with a single SIO connector in port, so what do you do? Do you keep removing the Atari SIO products one by one that ends the Atari 8 bit computer SIO Daisy chain just to plug in another Atari product that ends the Atari SIO Daisy chain again. The perfect solution to this Atari SIO port Daisy chain shortage is the Atari Apelink SIO Breakout product. It comes in several different versions bare board / kits or fully assembled product. The bare Apelink bare board and different Apelink Kits are perfect projects for the beginner level Atari person with only basic soldering skills.
Bill L. of NJ. Bill had two 8 bit computer products that either one would end the Atari SIO daisy chain. He wanted to run both products at the same time on his 8 bit Atari computer. So he ordered the assembled version of the ApeLink 13 Pin SIO splitter / breakout product "Thank you once again for the quick delivery of the APE-LINK device. It works perfectly! I can now hook up my Alien Group Voice Box I as well as my SIO2PC cable, both of which terminate SIO. I’ll be using it to archive the rare disk images that came with the Alien Group Voice Box I for the ATARI community. I’ll also be using it at Vintage Computer Festival East 2017 and Vintage Computer Festival Southeast 2017 for my ATARI exhibit."
The bare Apelink bare PCB board (light green top side (SIO female connector side) and Dark green solder side) can be configured / assembled several different ways.
1. Left and right SIO female connectors, with SIO Cable in top of the PCB edge)
2. Apelink bare board with 3 right angle Atari SIO female connectors.
3. Two Atari SIO 13 pin connectors, left and right sides, SIO cable in top and SIO cable out on the bottom edge of the ApeLink board.
Now all versions of the Apelink boards, Kits and fully assembled boards are now supplied with a New Best SIO cable wire color code chart that covers the most widely made (5 different manufactures made) 3 ft SIO cables Atari supplied over the years and the wire color differences between the different SIO cable manufactures!

Atari SIO Cable Information Tip: Over the 20 to 25+ years Atari produced their 8 bit computers (400 / 800 / 1200XL / 600XL / 800X / 65XE / 130XE / XE Game Machine, all used the 13 pin (triangular shaped custom made connector) female Atari SIO (Serial In Out) cable to interface external devices (Atari Disk drives, Atari Cassette program recorders, Atari 850 Interface, Atari Modems, Atari Printers and so on to their Atari 8 bit computers. Stock Atari made SIO cables (Atari had many many different world wide manufactures make the Atari SIO cables) came in a 3 and 5 foot versions. Most of the Atari SIO 13 pin cable connectors were hand assembled (top and bottom connector shells and main connector body) and then either screwed together (nut and screw) or riveted together or a few had Injected together solid bodies onto the SIO cable itself. About 80 to 90+% of all of the Atari SIO cables made over the years used the Molex type of internal (inside the SIO connector body) Spring Metal contact for the 13 female contacts. When you plugged in an Atari SIO cable into the Atari mating right angle 13 pin Male SIO connector (on all Atari 8 bit computers and external Atari 8 bit devices) the SIO Cable connector Molex spring contact made a single point contact with the mating Atari SIO Male round pin receptacle.
Considered by Best Electronics as one of the very best made 3 foot SIO cables Atari ever made, was the one that was made in Japan for Atari. What makes this Japan made Atari SIO cable better than any others made over the years are two reasons. One the JAE (Japan Aviation Electronics, letter marking on the outer SIO connector shells) 3 foot SIO cables used round female connector metal contacts inside the SIO cable connector body, so each mating SIO receptacle male pin made 100% (360 degree) contact with the female SIO cable round metal connector pin. Second reason is the JAE 3 foot SIO cables have an attached strain relief on the cable ends that prevents the SIO cable (as it goes into the 13 pin connector shells) itself from pulling out of the SIO connector body. Old Atari users (400 / 800 / 1200 computer era) remember that the very early Atari made SIO cables made, the SIO cable end would pull out of the SIO connector body (no internal cable strain relief device) and expose the 13 wires outside / backend of the SIO connector body. If this Atari SIO cable connection was inserted and extracted or moved a lot, the SIO wire connections inside the SIO connector body would end up breaking and you would end up with a bad SIO cable. Best Electronics has a very limited supply of the New Atari JAE 3 foot SIO cables in stock. If you would like one, please specify when you order an Atari 3 foot SIO cable.
