Subject: have an Osborne-1, would like to make it useful

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!
