Thanks for the tip... figures I wouldn't try eBay for that. ;) I was actually wanting one as an upgrade for my Coleco ADAM. I had installed a TIM board with the 9938 in one back in the day, and wrote some initialization software for it. Was thinking about building my own board to do the same again. -----REPLY---- Hi! The Coleco ADAM is a Z80 computer right? If you are up to some experimenting the other related item at the N8VEM that might be interesting to you is the PropIO. Using a shim socket, the PropIO can be interfaced to the Z80 CPU socket. Then with proper software support it can provide PS/2 keyboard, VGA, and microSD for your computer. Assuming of course the ADAM design is compatible. Basically if the ADAM can access an IO port it should work fine but the best way to be sure is to check the schematic. One of the N8VEM builders has done some experimenting on a Kaypro and a SpectraVideo 728 with the Z80 shim socket to PropIO and it worked fine in both cases. It might be a neat expansion option for you if you are interested. I am looking for some hardware experimenters to test the system out on some various Z80 computers. I am not aware of anything like it for the ADAM but don't follow it too closely either. If you are interested (or anyone else) please let me know. Thanks and have a nice day! Andrew Lynch PS, the PropIO shim socket approach *should* work for any of the N8VEM expansion boards so if you are interested in expanding your Z80 computer or adding peripherals to your Z80 home brew computer this might be helpful to you since you won't need to reinvent it. It could add simple interfaces such as IDE/FDC (DiskIO) or Zilog Peripherals (CTC, DART, dual PIO) as well as the PropIO.
