globeron Posted March 9, 2015 Share Posted March 9, 2015 Self Built PEB box ("Selfstbau") does someone know who built it? (we think it is from Germany). I got a magazine about Selfstbau from Austria, but does not look to be it. Is there a "TI Revue magzine from Germany, I think around year 1985 which has some description how to built your own PEB box ?) Still figuring out what all the cards are (I put some description next to it). One card is broken (2x loose blue wires and probably a condensator is broken) Thanks in advance. 1 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted March 9, 2015 Share Posted March 9, 2015 It looks like you have two 16K RAM boards in there, another board to interface with the console, and a weird one with the DIP switch on it that I'm not sure about. I haven't seen one quite like this before. Most of the other homebrew expansion boxes I've seen were designed to use regular PEB cards. You might want to ask Fred Kaal about this one though--he may know something more. 1 Quote Link to comment Share on other sites More sharing options...
Stuart Posted March 9, 2015 Share Posted March 9, 2015 The one with the DIP switch is a real-time clock plus 2K battery-backed RAM. It all looks rather nicely done. 2 Quote Link to comment Share on other sites More sharing options...
+OLD CS1 Posted March 9, 2015 Share Posted March 9, 2015 It looks like someone was inspired by a do-it-yourself S100 kit. Neat. 1 Quote Link to comment Share on other sites More sharing options...
globeron Posted March 21, 2015 Author Share Posted March 21, 2015 Thank you very much for the replies. It was using 32K (that I tested...before I broke the card with the "blue" electrical component on it and 3x wires. In April I am back in Netherlands and will see to get it fixed. (I was wondering if one of the cards is a kind of RAM-disk as the system does not have floppy disks and I was wondering how the programs get into the system, e.g. via cassette recorder only? or was the 32K only to utilize modules which need 32K, like EA ?).
