rockdoc2010 Posted August 30, 2019 Share Posted August 30, 2019 I pulled a happy out of storage and it did not do the power on sequence. I pulled the drive mechanism and tried it in a known good drive and the mech worked. I pulled the two chips from a known good board and installed the happy in it. No Joy! Your not gonna believe this..... I then installed the two chips that i removed from the drive when i installed it back in 1984. I still had the chips!!!!!!!! Now I have a working 1050 drive but the happy is dead. I am in need of and where do I find the following.. UM6502 94p64b-2583 HART-ECMT-R2 BIG GI ON PRINT 8638 CMA THANKS Douglas Quote Link to comment Share on other sites More sharing options...

I still had the chips!!!!!!!! Now I have a working 1050 drive but the happy is dead. Good troubleshooting! So with your work you have determined that the original 6810 SRAM, WDC controller, and 6532 RIOT are all still good. (Along with the original 2 chips you swapped back in--the 6507 CPU and Atari ROM.) Now, as for the Happy board. The primary IC's are a 6502 CPU, a proprietary 8KB mask ROM, and either three 2KB 6116 SRAM's (earlier boards), or 1 8K 6164 SRAM (later boards). Since your mask ROM date code is 8638 (38th week of 1986) I suspect you have the newer 8KB single SRAM chip board. I'd start by replacing the SRAM chips. I've revived two dead or flaky happy boards by only replacing these. Example eBay listings: 6116 2Kx8 SRAM: https://www.ebay.com/itm/254004576632 6264 8Kx8 SRAM: https://www.ebay.com/itm/223327507834 2 hours ago, rockdoc2010 said: UM6502 This is the 6502. It is a common part, and highly unlikely to have a problem from my experience. However, they are cheap if you want to get one to have on hand, eg: https://www.ebay.com/itm/112533588620 2 hours ago, rockdoc2010 said: 94p64b-2583 HART-ECMT-R2 BIG GI ON PRINT 8638 CMA This is the Happy's proprietary mask ROM. It has internal logic to switch between two 4KB banks when accessing specific memory locations in the ROM. This part is not easily replaced without possibly creating an extra 'adapter' board that adds the extra bank switching logic to an EPROM, or unless you can find someone to cannibalize one from an otherwise dead donor board...

Mclaneinc Posted August 31, 2019 Share Posted August 31, 2019 (edited) LOL re the HART acronym.....Excellent....Scotts brother had a sense of humour... I loved all the rumours re Mr Happy, that he was brought out by Atari back then when he did the ST cart (Discovery??) All rumours and Mr Happy himself has never commented on it (that I know of, I asked Scott when he was on here but him and his brother didn't discuss business other than what Mr Happy was doing for Scott) Edited August 31, 2019 by Mclaneinc 1 Quote Link to comment Share on other sites More sharing options...

I forgot about that. I wonder if it was coincidence, or a nod to inspiration from the Happy enhancement. Here's the passage from Page 1-3 of the Indus GT Field Service Manual: (Which doesn't appear to be on Archive.org yet, I'm going to correct that.) Quote The digital board will be referred to throughout this manual as the ‘WART’ board. The name is derived from the original project title for the development of the disk drive. ‘WART’ is an acronym for ‘Wonderful Atari Rotating Thing’. The WART board contains the Z80-‐A CPU, it’s controlling ROM/EPROM, a 2K RAM buffer and a Western Digital 2797 floppy disk controller (FDC) among other things. In later sections, we will discuss each of the major components on both of the boards.

Mclaneinc Posted September 1, 2019 Share Posted September 1, 2019 WART...Lol...Great stuff...Love to hear the history of these items although the Happy board has a special side because of the brothers role in Atari history. I had a friend who brought a Happy (810 one) for his machine here in the UK, needless to say he was using it for nefarious purposes and was on the phone to Mr Happy almost every day for about a month after getting it ask how things work and how to do a disk that was giving him issues.

I provided you eBay links to all the potential off-the shelf main ICs in post #2 of this thread. There's 1 HD74LSxx chip that should be commonly available as well. An original mask ROM can probably only be sourced from a donor board. Hopefully if you replace the other parts, it will be OK. Can you check if your board is 3 2Kx8, or 1 8Kx8 SRAM?

rockdoc2010 Posted September 21, 2019 Author Share Posted September 21, 2019 Thank you very much I am currently clearing the holes of solder for a socket for the one 8k chip which will be replaced. Kinda wondering why the power up sequence don't work if you have a bad ram chip? Wouldda thought a controller chip.. Quote Link to comment Share on other sites More sharing options...
rockdoc2010 Posted September 23, 2019 Author Share Posted September 23, 2019 Hey do you know if this is the proper orientation for the HART chip? The socket is reversed but the square pin is under pin one as this photo expresses. Quote Link to comment Share on other sites More sharing options...

rockdoc2010 Posted September 23, 2019 Author Share Posted September 23, 2019 That's great thanks.. The square pad is the deal. The socket was inserted 180 out. SRAM on the way Quote Link to comment Share on other sites More sharing options...
rockdoc2010 Posted September 23, 2019 Author Share Posted September 23, 2019 As it turns out when i opened up my happy drive J6 was in fact off of its plug my one pin. I am unaware as to what J6 does due to a loss of all my tech data. The plug was towards the front of the drive by one pin. Quote Link to comment Share on other sites More sharing options...

With that misconnected, it would not be able to read or write any data - although it may initially appear to seek and spinup/down for the poweron self test, and when closing the lever etc...

ratwell Posted April 25, 2021 Share Posted April 25, 2021 (edited) Happy 1050 Controller: https://archive.org/details/Happy1050ControllerInstallationAndUsageInstructions The LED on the CONTROLLER turns on and glows yellow whenever disk writing is enabled. This is a cautionary signal. It is suggested that you enable writing only when you actually intend to write. The following information is for CONTROLLERS that have the original factory jumpers installed. The lower three position switch on the CONTROLLER provides manual control of the disk drive write protect system. The normal disk drive write protect sensing system works as usual with this switch in the NORMAL lower position. Disk writing is inhibited whether or not there is a notch in the disk when this switch is in the center PROTECT position Disk writing is enabled regardless of disk notch when the switch is in the upper WRITE position This allows formatting and writing to the disk back side without punching holes in the disk. Please note that some lower quality disks may not work on the backside, especially in medium or true double density It is necessary that you manually turn the disk over to use the back side. If a software command is issued to protect or unprotect, this command overrides the switch position and the diskette notch sensing system. The technical section of the software instructions rev 7 or later describes these commands These features are also available on the DRIVE PROGRAM OPTIONS MENU when you boot the WARP SPEED SOFTWARE and select item 1. The upper two position switch of the CONTROLLER is the SLOW/FAST switch. With the two position switch in the lower position the ENHANCEMENT is in the normal fast buffered reading mode. With the two position switch in the upper position non-buffered (slow) operation is selected. Normally except as described below to enable fast writing, the only time you need to select slow mode is to boot a copy protected disk that will not boot in the fast reading mode that the HAPPY is in when you first turn the drive on. Please note that SLOW mode is not the same as UNHAPPY mode. In slow mode selected by the switch the HAPPY is still programable by the computer; slow mode has no effect on the HAPPY backup program The only way to completely lock out the HAPPY features is through the UNHAPPY mode selection of the WARP SPEED SOFTWARE, and this is usually not necessary.

The header is indeed normally "intended" for a happy controller as @ratwell indicated. In the particular drive pictured above, there is a small modification: The controller header is used as a source of +5V, which is used to switch power to either the ROM on the happy board, or the original 1050 ROM on the 1050 motherboard. Both have pin 28 lifted and connected to the wire from the switch. Quote Link to comment Share on other sites More sharing options...
+Peter Rabitt Posted April 27, 2021 Share Posted April 27, 2021 Hi, I have a board here in my 1050 that may or may not be a happy add on... The thing is it does not have any marking and the chips have been scrub off so you can not know what they are. It looked like a happy but as I read this and saw the pictures I find it does not look like a normal Happy drive board. Does anyone requnizes this board or what ever it is??. Yes it was in a 1050 mod date probably in the 1980's. Could be a clone..No other wires and it plug in to the main board. As you can see the "eprom" is rev 3.00??? The marking on the bottom side is 82135, I think... Peter Quote Link to comment Share on other sites More sharing options...

+Peter Rabitt Posted April 27, 2021 Share Posted April 27, 2021 If so how do you tell the difference. Is there soft/firmware out there to upgrade and use it??? Is there a manual (lol). Just got back into Atari and am trying to remember all of this from the 1980's when I was a Atarian... Been to long in the MS Windows world to long... Thanks for the reply...
