Sony CP/M machine?

I remember going to see one, but didn't bite because they wanted about six grand for it, and that is a bit much, even in Canada. Regards Charlie Fox

I had a business meal tonight and after some discussion I found out that one of our guests is sort of into collecting old computers (basically he never got rid of any of the systems he's bought over time). One of the systems he mentioned he had was a Video Brain. Apparently this is a video game system. I *think* I vaguely remember hearing about this system. At any rate I'm curious about it and was wondering if anybody knew what it was as we both had too much tequila for him to describe and for me to comprehend it. I told him of my plans for the First Annual Vintage Computer Festival (which, by the way, is still on...I'm still in the planning phases) and he mentioned that he had close contacts with a show called The Computer Guys on the Discovery Channel and would arrange for me to meet with them to discuss possible coverage of the show. Very nice! Sam ------------------------------------------------------------------------------- Computer Historian, Programmer, Musician, Philosopher, Athlete, Writer, Jackass

Help with Apple Lisa 2

by kaikal＠MICROSOFT.com

Hi all, I just acquired a Lisa 2/10 and I'm trying to figure things out. The system starts to boot from the hard drive and comes up with a MacWorks/Sun Remarketing logo, then asks for a diskette. Looks like it's running MacWorks XL, is that correct? The system still has regular Lisa H/88 ROMs so it's not messed with hardware-wise. How come it wants a diskette and won't boot from the HD? I tried putting in a System 1 diskette from my Mac 128 and it gave me the "Welcome to Macintosh" splash and then died with a Sad Mac FE0002. Do I need a special Mac System version diskette to boot this sucker? Any info appreciated!! (anyone have a spare keyboard? I need a few keys) thanks Kai

Flex for 6809/6800

by bluesky6＠ix.netcom.com

Does anyone know if one can still get Flex for the 6809 or 6800? There're people archiving and using CP/M stuff but it seems a waste to let a very simple and neat OS like Flex go the way of the dinosaur. Ben

Auction: Odds and Ends, Power Supplies, etc.

by gmast＠polymail.cpunix.calpoly.edu

I am still sorting through my stuff and have a few odd items up on the eBay auction. These type of things go pretty cheap (a buck for 3 power supplies and 4 RF adapters? Cheaper than the Goodwill!) but are sometimes hard to find (especially when you need one...power supplies?). Anyway, all you have to do is go to the link listed and check the price. Remember to figure shipping into what you want to pay. I'm in CA.

collection value

by lynn＠ferberts.com

Are old (classic) computer magazines worth more now than the issues price? Example: original first issue of BYTE magazine? Or can I tell my husband to throw them out and give away the tin shed? Lynn Lynn Perez-Hewitt lynn(a)ferberts.com P.O. Box 1630 Oracle, AZ 85623 520.896.9316
