PC Ephemera

I've been going through some old files and discovered a few of documents that I can't decide if they belong in the the shredder or with someone who gives a darn about them. Does anyone remember the background behind the "Explorer 88 PC" by Netronics R&D circa 1983? Was it a do-it-yourself PC kit? Anyway, I've got the schematics for the thing. I've also got the guide by Purple Computing for their Purple -2 Kit on how to put 256K on your PC motherboard by cutting and changing a few jumpers and then adding a board that attaches over the memory array that holds 64K DRAMS. I'd forgotten that the original PC was limitied to 64K on the mobo. Time erodes one's memory. I've also got the manual for the Teletype 410640 printer logic card assembly. IIRC, this was for the Model 40 line printer. It includes schematics and parts layout. ...and I discovered a complete unopened OEM kit for MP/M II, complete with licensing pricelist and 8" floppies. I'd forgotten all about it. (I may hang on to this one for the time being). Funny thing is that I don't remember half the stuff in my files... Cheers, Chuck
