+tf_hh Posted April 4, 2016 Author Share Posted April 4, 2016 Are we able to order a sys-check now Jurgen? I´ve 20 pieces of PCBs here. Try to assemble them in the next 1-2 weeks. The last 2 weeks I´ve had holiday, so there was a lot of spare time to assemble over 65 PCBs with BitWriter and Sys-Check. Now I´m back at work and spare time isn´t so much. I will offer it in the Sys-Check thread when I´m ready... Jurgen Quote Link to comment Share on other sites More sharing options...

Roydea6 Posted April 10, 2016 Share Posted April 10, 2016 BitWriter received and now working. Great instructions and product. I now have two 1050 drives on my desk top for all my Floppy needs.. 1 Quote Link to comment Share on other sites More sharing options...
+Allan Posted April 10, 2016 Share Posted April 10, 2016 I got my Bitwriter today. Thanks, Jurgen. Allan 1 Quote Link to comment Share on other sites More sharing options...
AtariGeezer Posted April 10, 2016 Share Posted April 10, 2016 My BitWriter came in Friday, still need to install it into a virgin 1050 Thanks again Jurgen for another fine product :thumbsup: 1 Quote Link to comment Share on other sites More sharing options...

ijor Posted April 30, 2016 Share Posted April 30, 2016 Yes, Brian there is.. i will send it to you... even the BitWriter cannot copy the protection on the original Super Archiver disks See my article: http://vapi.fxatari.com/docs/sa.html 1 Quote Link to comment Share on other sites More sharing options...
ijor Posted April 30, 2016 Share Posted April 30, 2016 the disk is physically damage and then the software is rearranged around it with the relevant sector information embedded in the software... this was done for each and every copy... so no two disks were exactly the same and the relevant code was different for each disk That's not exactly what I found in the copies I've seen. And there is no reason to physically damage the surface. Physical alterations to the disk surface (such as laser hole) can only verified reliably by writing to the disk. The copies I've seen have weak bits on the header of one sector. Which is just a magnetic protection. It is possible that the actual sector is different in each copy, I don't remember that.

ijor Posted April 30, 2016 Share Posted April 30, 2016 When I made the first prototype after re-engineering, I use some GALs to replace the bunch of TTL chips. But it doesn´t work correct. The written copies aren´t exact, the copy protection detection of some tested games fails. So I decide to use the classic TTL chips as used in the original board. P.S.: Yes, there are a few boards left Hi Jurgen, Are you releasing the technical info (schematics, firmware)? I though the original had some kind of programmable logic. Never seen an actual hardware, but I remember a picture showing some hidden chip(s) buried in epoxy? Still some boards left? 1 Quote Link to comment Share on other sites More sharing options...

+tf_hh Posted May 1, 2016 Author Share Posted May 1, 2016 Are you releasing the technical info (schematics, firmware)? I though the original had some kind of programmable logic. Never seen an actual hardware, but I remember a picture showing some hidden chip(s) buried in epoxy? Still some boards left? Actual no boards are left, but two other users want one, so I´ve ordered 10 more PCBs and parts. Will take 3-4 weeks until they are finished. Normally all my projects are released fully to the public incl. schematics and so on. Because this project is mostly made of re-engineering (by permission) I´ve the ask the involved people. If everything is fine, surely I will publish all. No, both parts (Super Archiver and BitWriter) doesn´t use any programmable logic. The Super Archiver is only a 2 KByte SRAM, a 4 KByte EPROM and one 74LS00 glued in epoxy. The BitWriter itself has some 74LS00, 74LS193, 74LS251 and 74LS74 onboard, followed by a PIA (6520 or 6821) and 8 KByte SRAM (6264). The real power - and this is the amazing part for me - of both projects are packed in the software. The hardware is "only" to enable breakout the limits of the FDC-circuit in the 1050 original PCB. Not more. Kudos to Bob Puff for this great work of all. This is the original, full populated BitWriter board. The black block in the middle is the Super Archiver: The following both scans are the naked PCB after I´ve removing all parts to see what´s going on under there Jurgen Quote Link to comment Share on other sites More sharing options...
+tf_hh Posted May 1, 2016 Author Share Posted May 1, 2016 Hi still possible order one? Thx At this time all boards are sold, but I´ve ordered 10 more PCBs and parts for it. In 3-4 weeks I´m ready and can deliver some more. Jurgen Quote Link to comment Share on other sites More sharing options...

When I thought that the BitWriter had some kind of programmable logic, I wasn't thinking exactly on processing power, but more on protecting the design. We know that CSS (don't know if it was Bob himself or not) liked to protected his products, almost at the paranoid level. Would be very interesting to see the schematics, but just by the components I can get an idea of its principle of operations. Thanks again. 1 Quote Link to comment Share on other sites More sharing options...
ndary Posted May 1, 2016 Share Posted May 1, 2016 after 25 years i completed a project of OCR's the SCANIT documentation i had, this project was on hold for 15 years and recently with the help of Larry i was able to complete it 25 Years ago i bought the Super Archiver from B&C, it came in a big box with a floppy, instillation manual and the SCANIT book few years later i bought a second Supper Archiver chip with the Super Archiver 2 software that support Enhanced Density disks.. but this time i got a photocopy of an older version of the SCANIT manual in poor quality.. so owners of the Super Archiver or BitWriter Replica here is the Manual and disks.. now you can read yourself how to use the software on your drive to create protected tracks enjoy SCANIT.doc SCANIT.pdf The Super Archiver 3.02.atr The Super Archiver II 3.03.atr 7 Quote Link to comment Share on other sites More sharing options...
+tf_hh Posted May 1, 2016 Author Share Posted May 1, 2016 Thanks Jurgen. When I thought that the BitWriter had some kind of programmable logic, I wasn't thinking exactly on processing power, but more on protecting the design. We know that CSS (don't know if it was Bob himself or not) liked to protected his products, almost at the paranoid level. Oh yes... he does! For example, in the BitWriter circuit the "R0" input from PIA are not as usually connected to "A0" from CPU (and "R1" to "A1"), they are exchanged... R0 is connected to A1 and R1 to A0... of course I miss that point and the first prototype PCB won´t work until I look more exactly... 1 Quote Link to comment Share on other sites More sharing options...

Bikerbob Posted July 26, 2016 Share Posted July 26, 2016 Just a quick question, because I have already gone there.. but my mega speedy does everything this bitwriter does .. and more correct? My megaspeedy is a little more evasive install and the faceplate in front. James Quote Link to comment Share on other sites More sharing options...
+tf_hh Posted July 26, 2016 Author Share Posted July 26, 2016 Just a quick question, because I have already gone there.. but my mega speedy does everything this bitwriter does .. and more correct? Not exactly. The MegaSpeedy is able to emulate the Super Archiver, but not the BitWriter. The BitWriter is needed to copy some special copy protections. But the BitWriter could be much more, it´s only a question of software. Like some other projects from Dropcheck for example, the main reason why I make the BitWriter Replica was keeping such a fantastic unit alive. The main goal of the MegaSpeedy was to enable as much as possible enhancements for the 1050 in one single expansion. Jurgen Quote Link to comment Share on other sites More sharing options...
