+Vorticon Posted February 26, 2018 Share Posted February 26, 2018 Hi. I found this HRD board under a stack of other TI stuff today and had totally forgotten about it. I think I got it a one of the Chicago Faires several years ago. It does not seem to work and I'd like to fix it if possible. The battery is definitely dead. Pin 8 of the chip immediately below and to the left of the Zippie sticker is bent upwards and there was something soldered to it in the past, but I can't seem to find a loose wire anywhere. I can't tell which version of the HRD it is. Clearly some modifications have been made and there is a mysterious "Zippie" sticker on it. Can you guys help me identify this board properly? 1 Quote Link to comment Share on other sites More sharing options...
Sinphaltimus Posted February 26, 2018 Share Posted February 26, 2018 (edited) Vorticon - Looking at the back of the board.See the WHITE TAPE on the wire near the top left. Count from that solder point straight down, at some point you'll shift slightly right to continue counting. the 23rd solder point looks like it may have rotted away across that trace.Possibly breaking it? I doubt that's your issue but something to note with a fresh pair of eyes on just the photos.

Thanks for the tip I'll definitely have to fix that. 1 Quote Link to comment Share on other sites More sharing options...
atrax27407 Posted February 26, 2018 Share Posted February 26, 2018 Previous owner was probably Dave Zipple hence the sticker. Quote Link to comment Share on other sites More sharing options...
+Schmitzi Posted February 26, 2018 Share Posted February 26, 2018 Is this a HRD-2000 ? And what is the switch for ? Memory "reset" (= power off) or so ? Quote Link to comment Share on other sites More sharing options...
+Vorticon Posted February 26, 2018 Author Share Posted February 26, 2018 Previous owner was probably Dave Zipple hence the sticker. Ah! So it's zipple and not zippie! One mystery squared away. Quote Link to comment Share on other sites More sharing options...
atrax27407 Posted February 26, 2018 Share Posted February 26, 2018 The switch is probably the mod to "hide" the card. Quote Link to comment Share on other sites More sharing options...
+Vorticon Posted February 26, 2018 Author Share Posted February 26, 2018 So is it an HRD 2000? 1 Quote Link to comment Share on other sites More sharing options...
marc.hull Posted February 26, 2018 Share Posted February 26, 2018 So is it an HRD 2000? Yes it is most definately a HRD 2000. And looks to have both change notice mods done to it. Quote Link to comment Share on other sites More sharing options...
+Vorticon Posted February 27, 2018 Author Share Posted February 27, 2018 Yes it is most definately a HRD 2000. And looks to have both change notice mods done to it. Hey Marc! Good to hear from you. What are the change notice mods? Quote Link to comment Share on other sites More sharing options...
marc.hull Posted February 27, 2018 Share Posted February 27, 2018 1) Switch to turn the card off so it won't hang your console if your ROS gets botched and 2) the power on/reset mod to prevent your ROS from getting botched. Have you tried the CFG program on it ? Quote Link to comment Share on other sites More sharing options...
+arcadeshopper Posted February 27, 2018 Share Posted February 27, 2018 that is one hell of a toggle switch Quote Link to comment Share on other sites More sharing options...

Have you tried the CFG program on it ? I'll play with it today as I just got off service. I never got to try the CFG program because the board always hung my system as I vaguely recall. Also need to fix that bad solder joint Lenny pointed to and replace the battery. I'll report back later today. Quote Link to comment Share on other sites More sharing options...
+Vorticon Posted February 27, 2018 Author Share Posted February 27, 2018 Success! I replaced the 3.6V alkaline battery and fixed the bad solder joint and now the board was being recognized by the CFG program. I was able to create 2 720 sector disks and read/write to them without issues. Total size of HRD is 384K. Now I already have a functional 1meg HRD courtesy of Marc, so I'm going to put the HRD 2000 on Ebay as it is too small for my needs. Thanks for the help guys. 4 Quote Link to comment Share on other sites More sharing options...
marc.hull Posted February 27, 2018 Share Posted February 27, 2018 Good. Another cheese grater lives. What do you want for the 2000? 1 Quote Link to comment Share on other sites More sharing options...
Opry99er Posted February 28, 2018 Share Posted February 28, 2018 (edited) Hey Walid, if Marc passes, I would be potentially interested. Can these be upgraded to a meg, fellas? Edited February 28, 2018 by Opry99er Quote Link to comment Share on other sites More sharing options...
marc.hull Posted February 28, 2018 Share Posted February 28, 2018 The card should do just right at 1mb unformatted. Of course that's stacking 3 high to 32 chips (I believe that's correct.) Good thing is that it doesn't have to be done all at once. It can be remodeled as you go. Quote Link to comment Share on other sites More sharing options...
marc.hull Posted February 28, 2018 Share Posted February 28, 2018 And, didn't think and I put you on the spot Walid. Feel free to tell me to FO. Sorry. 1 Quote Link to comment Share on other sites More sharing options...
+Vorticon Posted February 28, 2018 Author Share Posted February 28, 2018 Actually I put the card on Ebay already with a starting price of $99 and someone already has placed a bid on it. Frankly I have no ideas what these are worth... eBay Auction -- Item Number: itm/152925060248?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649 2 Quote Link to comment Share on other sites More sharing options...

+9640News Posted March 1, 2018 Share Posted March 1, 2018 I assume there is no issue using this card on a Geneve. Would it be configured as an 8 bit or 16 bit card? Quote Link to comment Share on other sites More sharing options...

+mizapf Posted March 1, 2018 Share Posted March 1, 2018 I assume there is no issue using this card on a Geneve. Would it be configured as an 8 bit or 16 bit card? There is no 16 bit data bus on the Geneve. Anyway, I thought only the SNUG HRD16 (https://www.s-n-u-g.de/hrd16/index_en.php) allows for 16-bit access.
