Omega-TI Posted January 17, 2014 Share Posted January 17, 2014 http://www.ebay.com/itm/TEXAS-INSTRUMENTS-TI-99-4A-PLEASE-READ-DETAILS-/201021426347 guy claims it's TI99/4a. could it be someones idea of a home brew memory card? It looks to me like it's a Horizon Ram Disk modified to work without the P-Box. I cannot tell how big the ribbon cables connector is from the picture.

Willsy Posted January 17, 2014 Share Posted January 17, 2014 Yep. Agree. Looks like a ram disk to me. Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted January 17, 2014 Share Posted January 17, 2014 The board is definitely an HRD--although the RAM chips used aren't normal. That's the first time I've seen one using skinny DIP RAM. The box looks like an aluminum kit box, and the cable looks like an IEC PEB extender cable. Interesting use of regular components to avoid buying a PEB.
