Belles) Organization: Crash TS, El Cajon, CA Lines: 33 Keywords: S-100 Microdesign IMSAI frontpanel I am looking for information on the Microdesign MR-8 ROM/RAM S-100 board, part # 440-1011A, Assy # 720-1011B. I'm trying to get the board to run in a 4Mhz or better environment, but can't seem to get the 2102 memory chips to run in a 4Mhz environment. The part #s for the memory chips are 2102A-2 or 21L02B with the manufacturer's mark like the one immediately to the right. ################## If anyone knows or has any info #### on this board, don't hesitate to ### ############# let me know. I am also looking #### #### for any available information on ############# ### modifications to the IMSAI and/or #### Wamemco S-100 frontpanels, and what ################## (if any) mods were made to these boards to make them a little better running, especially considering the memory loading I have of approximately 304K on the box I'd like to run a frontpanel on. I'm also looking for a set of schematics on the IMSAI EXP-10 motherboard, as I have some parts missing and some cuts to the one I have, as well as 2 connectors that I have no idea of the use for. The rev. # on the EXP-10 is REV 2.2, AR 1.2, if that helps. Oh yes, if you want to contact me personally, I'm at 619/282-5661, USNail 4037 34th Street #4, San Diego, CA 92104. Thanks! -- Kevin J.
