+InsaneMultitasker Posted March 15, 2016 Share Posted March 15, 2016 An enigma inside a riddle. Any chance you can contact the seller to inquire about its origin? Quote Link to comment Share on other sites More sharing options...
RickyDean Posted March 15, 2016 Author Share Posted March 15, 2016 Any chance you can contact the seller to inquire about its origin? I originally did, but he was selling these in some stuff that he had gotten, somewhere, said he was told they were SCSI to IDE adapters. The price was cheap after I found they were not what I thought they were, instead of sending them back, I thought I would research and see if there was a use for them.

RickyDean Posted March 15, 2016 Author Share Posted March 15, 2016 Since we are on the subject, does anyone know if the Acard AEC-7722 is programmable by the same usb serial cord that can be used by the Gotek. The area on the picture has four holes that on the other side are marked GND,RX,+5V,TX and a person on the following site has apparently pulled the chip and reprogrammed it with a version that would allow use with a HDD. I have the binary that, that site talked about, but had to google for it.

RickyDean Posted March 16, 2016 Author Share Posted March 16, 2016 (edited) Here is my actual 7722, does anyone know if a USB To RS232/TTL PL2303HX Cable Adapter COM Module Auto Converter for Arduino will let me program this chip, Microchip SST39vf400a, at the 4 solder points mentioned in the prior picture and if so what software can I get that will allow it to happen.

RickyDean Posted March 22, 2017 Author Share Posted March 22, 2017 In post #14 I placed this information, today on ebay I found the answer Consensus says more pics so here they are: Attached Thumbnails 1 Quote Link to comment Share on other sites More sharing options...
+OLD CS1 Posted March 22, 2017 Share Posted March 22, 2017 That ain't SCSI. Quote Link to comment Share on other sites More sharing options...
RickyDean Posted March 22, 2017 Author Share Posted March 22, 2017 That ain't SCSI. Your right, the guy lied on the ebay sale, But that was last year, so I didn't get to contest it, as know one could figure what it was. Oh well.... Quote Link to comment Share on other sites More sharing options...
+Schmitzi Posted March 23, 2017 Share Posted March 23, 2017 so maybe this is just an abused connector, for "hotswapping" FDDs ? 1 Quote Link to comment Share on other sites More sharing options...
RXB Posted March 23, 2017 Share Posted March 23, 2017 (edited) That ain't SCSI. Hmmm yes they are as i had these adapters and cables. They came off of HP Servers I got at a Computer Recovery place. As far as the box that had them they have several types including these that appeared to be hot swap 80 pin ports. Also saw a 50 pin version too. I also thought they were for something else till I saw the boxes the SCSI drives and Cards came from. https://www.google.com/imgres?imgurl=http%3A%2F%2Fthumbs2.ebaystatic.com%2Fd%2Fl225%2Fm%2Fmj7MsOSWAHYpmPXl7oW3CXQ.jpg&imgrefurl=http%3A%2F%2Fwww.ebay.com%2Fbhp%2Fscsi-adapter&docid=l0FTaP7DOpABeM&tbnid=sK3E-kOxEYAnZM%3A&vet=10ahUKEwiSjcytnu3SAhVJKWMKHVF0AKwQMwg4KAAwAA..i&w=225&h=225&bih=950&biw=1920&q=scsi%2060%20pin%20adaptor&ved=0ahUKEwiSjcytnu3SAhVJKWMKHVF0AKwQMwg4KAAwAA&iact=mrc&uact=8#h=225&imgdii=ucGBY6h6f2DuuM:&imgrc=sK3E-kOxEYAnZM:&vet=10ahUKEwiSjcytnu3SAhVJKWMKHVF0AKwQMwg4KAAwAA..i&w=225 Edited March 23, 2017 by RXB Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted March 24, 2017 Share Posted March 24, 2017 Look carefully at that hot-swap adapter, Rich. It is not normal (it has a round end and a pinty end inside the connector). A normal 80-pin hot swap is mirror image at the ends, not different like this. I've built HP servers before and hadn't seen this type of connector on them. . .you may have found something different though, as HP sometimes does very strange things with their hardware to try and keep things proprietary. 2 Quote Link to comment Share on other sites More sharing options...
+Schmitzi Posted March 24, 2017 Share Posted March 24, 2017 yep, IIRC, I have checked that at the start of this thread, they just look a bit like HP SCA, but they aren´t Quote Link to comment Share on other sites More sharing options...
luckybob Posted March 28, 2017 Share Posted March 28, 2017 I know i'm a bit late, but if you want to get cheap acard adapters, they are often pre-installed on IBM dvd sleds. case in point: http://www.ebay.com/itm/371434273989 They only work on atapi devices afaik, but they do work on zip and ls120 drives. I just wish there was a way to allow hard drives to work on them. 371434273989 2 Quote Link to comment Share on other sites More sharing options...

I believe there is a way to change the firmware to use ide hard disks,but even zip drives are acceptable for the TI. 1 Quote Link to comment Share on other sites More sharing options...
luckybob Posted March 28, 2017 Share Posted March 28, 2017 no problem. I just wish I could find one or two of these at a reasonable price: http://www.ebay.com/itm/262472224560 I have lots of small laptop drives around, and to drop one into the many IBM ps/2 systems I have would be a godsend.

There is a way to use sd cards http://www.ebay.com/itm/SCSI2SD-v5-3-5-board-bundle-with-8GB-SanDisk-microSD-card-/192133072022?hash=item2cbc060496:g:z4AAAOSwFnFWBHDt and this is fairly decent.

luckybob Posted March 28, 2017 Share Posted March 28, 2017 I've seen that guy and it is tempting. But I have a neurological condition, at least when it comes to certain computers, and it requires me to get the absolute fastest thing I can for a particular system. I have an IBM model 95 that I'm struggling to 'pimp out'. I upgraded it to scsi @ 40mb/s. That little SD card can't cope with those speeds. The ACARD supposedly can. Other systems, even my literal pile of aio macs. That sd card would be just fine, but I have plenty of hard drives around, so I can't justify the cost for those systems.

+Schmitzi Posted March 28, 2017 Share Posted March 28, 2017 Hi, if I pimp my ride I giv´em a new fresh & silent cooling first >>:0) maybe you need a watercooling system here ? but it doesn´t makes it faster (unless you pimp the cpu or so) xXx Quote Link to comment Share on other sites More sharing options...
luckybob Posted March 29, 2017 Share Posted March 29, 2017 Not to get too far off topic, but it started as a 486/66 with 16mb of ram, and if I can find like 2 more parts, it will be a pentium mmx 200, 256mb ram, and ssd. Quote Link to comment Share on other sites More sharing options...

You could use the Scsi to Ide route and then a ide to sata adapter. Quote Link to comment Share on other sites More sharing options...
