Re: OSI-300 Replica

Hi Christopher,

This is a nifty project--I just noticed it, and am surprised nobody commented on it. The next step is to get Zork running on it :-)

Re: C 8P system on eBay

It's crazy. It looks like a positive feedback loop where they get high hopes looking at other Ebay listings without checking prices on actual completed sales. Actual sales over the past couple of years show the highest auction for a working OSI system, a working C4P 5" disk system with software, for...

I just saw this, or I would have bid on the collection. Did someone here win the auction?

Re: bad links in Files section?

Hi Chris,

Sorry about that. The HTML editor changed, and now it's a bit more convoluted to add relative links. I've fixed the links.

I thought I might be able to locate a good dump of the Tutorial 2 disk, but was not able to do so. I will see if I am able to scrounge a good copy.

Re: DOS/65 Richard Leary

Rich, This is quite exciting! I had not realized there is a section in phpBB that allows the file size limits to be modified. Apparently the system installs with some arbitrary limitations to discourage spam and advertising. The file size was limited to 250K, number of attachments to 3, and attachme...

Re: DOS/65 Richard Leary

Rich, that's awesome. Next week I will have a little time and plan to to some updates to the site, and will gather together the DOS/65 materials into their own section.
