by P Gebhardt

Hello list, out of curiosity: Does anybody know where the two pictures of the Siemens 4004 CPU uploaded on http://bitsavers.org/pdf/siemens/4004/Model_15/pictures/ where taken? Are these from the unit being part of the SAP collection at CHM? Cheers, Pierre ----------------------------------------------------------------------------- http://www.digitalheritage.de

Does anyone have a VT52, TU56 controller, or Apple II rev 0 available for sale?

by Ryan de Laplante (Personal)

If you or someone you know might be willing to sell, please contact me off-list. I'm in Canada, near Toronto. The TU56 controller is for a PDP 11/45. I know about the VT52 in Australia on eBay right now. Shipping something that large and heavy from Australia is too much, and we have different electrical outlets in North America. I'm also looking for certain NightOwl shareware CDs from the BBSing era: 1 - 9 (except 4 and 6), 24, 26, Games #1, Games #3, Windows Vol 1 & 2. Maybe some Boardwatch magazines as well. Anything BBS related.

Microsoft & Apple

by Murray McCullough

I had not realized it was 27 yrs. ago that Microsoft ‘gave’ Apple $150-$200 million. It was done to keep Microsoft safe from regulators - for its monopoly practices. Later did the lawsuits end between Apple and Microsoft. Did this save Apple? Haven’t researched this enough to deduce a learned response! Happy computing, Murray 🙂
