Verault Posted February 2, 2022 Share Posted February 2, 2022 Doing some work on a couple ATARI 1050 Floppy drives I discovered an addon board. Here are some photos. Any idea what this thing might be? It plugs into the 6507 socket and the main board does NOT have the Tandon 188063-001K (mask rom?) Weird thing is all the identifiers on the small board have been sanded off! You can see wear marks. Only the eprom has anything readable.

Beeblebrox Posted February 2, 2022 Share Posted February 2, 2022 (edited) @Verault at a guess either a Happy clone or US doubler ... I vote for the former. Perhaps Lazer? Edited February 2, 2022 by Beeblebrox Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted February 2, 2022 Share Posted February 2, 2022 (edited) Isn't that the Atarimax Happy clone.. not a lazer,, they were done on what looked like hand etched boards, or cheap transfers..

Verault Posted February 2, 2022 Author Share Posted February 2, 2022 This board does not look hand etched at all. So what is the AtariMax Happy clone exactly? Quote Link to comment Share on other sites More sharing options...

The Atarimax Happy is smaller and the chips are side by side. Quote Link to comment Share on other sites More sharing options...
Verault Posted February 2, 2022 Author Share Posted February 2, 2022 Since this is the only readable part of the eprom in ascii I take it still not enough info? Quote Link to comment Share on other sites More sharing options...

Verault Posted February 2, 2022 Author Share Posted February 2, 2022 Thanks guys.. but WHAT EXACTLY does the happy clone do? Quote Link to comment Share on other sites More sharing options...
TGB1718 Posted February 2, 2022 Share Posted February 2, 2022 (edited) Happy is an enhancement the allows DD disks, high speed SIO and also copies protected disks A clone is a copy made by someone else Edited February 2, 2022 by TGB1718 1 Quote Link to comment Share on other sites More sharing options...
Verault Posted February 2, 2022 Author Share Posted February 2, 2022 Ok very cool. The first are straight forward. How exactly would copying protected disks work on it however? special software? Quote Link to comment Share on other sites More sharing options...

Verault Posted February 2, 2022 Author Share Posted February 2, 2022 (edited) I found this: http://www.oldcrows.net/~patchell/atari/duplicator.html This one also has the chips info sanded off in the photo.

TGB1718 Posted February 2, 2022 Share Posted February 2, 2022 He wrote the documentation on an ST, here's the decoded STWRITER File if it helps. Look like you will need some software to be able to use this board. Nice that he made the drive programmable too Duplicator.txt Quote Link to comment Share on other sites More sharing options...

+kheller2 Posted February 2, 2022 Share Posted February 2, 2022 https://archive.org/search.php?query=1050 duplicator https://archive.org/search.php?query=DTI+1050 The support disks should be archived somewhere. A few things to remember: 1) DD disks formatted on this drive might have issues on other DD drives. Vice versa is not a problem. This is due to the way the Duplicator formats the first 3 sectors in DD mode. 2) You are always in track buffered mode (hello damn fast disk boots!) There is a small boot disk to deprogram it and leave it in stock mode until power cycle. Having said that, the 1050Duplicator was my main drive for many years and was way faster than my USD. 1 Quote Link to comment Share on other sites More sharing options...

The latest ZIP from a8preservation.com includes ATX images of v2.0,v3.0, and v5.0 software. These are listed under the name Duplicator Module and are from flux dumps of original disks, but haven't been verified.

Verault Posted February 10, 2022 Author Share Posted February 10, 2022 Someone mentioned to me that the actual (not clone) version of the upgrade board had a built-in program you can run by closing the floppy lever (with no disk inserted). I cant say whether thats true or not but it does not work for me and this board. Quote Link to comment Share on other sites More sharing options...

xrbrevin Posted February 10, 2022 Share Posted February 10, 2022 mini speedy does have - boot without a disk and the latch up for various disk-related utilities Quote Link to comment Share on other sites More sharing options...
Verault Posted February 13, 2022 Author Share Posted February 13, 2022 (edited) Well the drive came out real nice. The metal badge still had the plastic sticker on it to peel off and after retrobright it looks brand new. And it came with its own vinyl dust cover. Im pretty happy with it all.

E474 Posted March 17, 2022 Share Posted March 17, 2022 Hi @Verault, Thanks for posting pics of the Duplicator board, is there any chance you could post pictures of the other side of the PCB, and maybe a few more of the top side, but maybe with a better view of the trace layout? Just curious how simple it would be to reproduce the board, given the firmware is available? Also, if anyone also has such pictures or a schematic would they mind sharing too? TIA!
