All — Now that I’ve finished recreating two Lomas boards (the Color Magic and the Thunder 186) I’m looking to fill-out a mass-storage option. A 2-board system will run DOS 3.31 with 256k; I added two CompuPro ram boards to get 640k. Lomas had a SCSI board (which added an RTC and 4 serial ports), and there’s a great alternative, the Lifeboat SCSI (for the Z-100 machines). But, there are various challenges that I’d like to ask for help on. On the Lomas side, I have the board and software but not a manual or schematics, and I haven’t found them on-line anywhere. I still need to reverse the PAL which is doable. On the Lifeboat, their manual has the schematics and PAL equations, but no software or ROM firmware. If anyone can help out with either of these, let me know. Thanks! Rich http://cini.classiccmp.org/ Long Island S100 User’s Group Get Outlook<https://aka.ms/qtex0l> for iOS
