I remember getting 8K SRAMS for my H-8, and sellcing rows of 16K > DRAMs for Apple ][s. 64K DRAMs? This guy was *spoiled*! ;^) Oh, we're me-tooing, are we? I just found my first computer out in the shed while I was looking for something useful. 20 years and a couple of months old, Z-80 with 2 2112 static RAM chips. Remember them? 4x256 bits. The whole machine had 256 bytes, so I wire-wrapped a 4K board, but could only afford 8 2102s. Then I moved to S-100, because Bill Godbout was offering 8 K memory boards at prices I could only dream about in Germany. Greg
