Return-Path: <@USC-ECLB.ARPA:info-cpm-request@AMSAA> Message-ID: <158@lll-lcc.UUcp> Newsgroups: net.micro.cpm Hi folks. I have a very very old (brown case) Osborne 1 that I'd like to get some use out of. I just recently dusted the little bugger off and put in a new power supply (AGAIN!), and I have a few questions. Re: double density upgrade Which one should I use? I can go to The Valley and get myself an Osborne made (and designed? uh oh!) upgrade. However, I have seen ads from a Texas firm that sells a DD upgrade. Does anyone know about it? Re: buggy rom software / bios source on disk? In the version that I have (1.43? 1.36? can't remember now), the ROM software was written by someone who didn't know CP/M coding conventions (CP/M is an 8080 operating system, therefore the z80 registers are sacred and are not to be clobbered), so I can't use things like Turbo Pascal or TLC Lisp. Sniff sniff. Is there an upgrade that I can get that will fix the roms? Does anyone have the BIOS source code on disk? One could patch around the rom brokenness that way... thanks muchly! -- Gee, usenet is almost as fast as US mail! andy beals bandy@lll-crg.arpa {ihnp4,seismo,qantel,sun}!lll-crg!bandy LLNL, P.O. Box 808, L-419, Livermore CA 94550 (415) 423-1948 -------------------- Andy, I have a blue-case Ozzie with the Osborne double density board, and it works just fine. I understand that some of them have trouble with single-density disks, but mine doesn't. Have no first hand knowledge of Nuevo (that outfit in Texas) products, but everyone I have heard of with their stuff raves about the product and the service. Probably a safe try. ...Dick Stanley
