For the same reason that they put money in collecting tins - not just for charities but for other organisations - it's a good cause. I'll subscribe! No-one should be expected to, but I think you'll find more people are prepared to than you expect. I'm prepared to - I get my money's worth anyway (technical data for my several PETs, VICs and my 64), and I would be quite happy to see the stuff go PD thereafter. Returning briefly to the Commodore B series, how do the 8200 series machines fit in? I see old documents refering to the B and P series, and older ones refering to the 500 and 700 series (I think respectively), but the machines I've actually seen from that period are called 8296. There were two models that I've seen - the 8296D (with internal disk drives) and the 8296 (without). The motherboard is identical - two banks of 64k RAM, (I think) a high speed (2MHz?) 6502, and a couple of chips which you unsolder and move to adjacent positions for 40 column mode. The case is similar to the 8032SK - rounded, plasticky PET case with large green screen and separate keyboard, but returns to the edge connectors for the IEEE488 and user ports. The internal disk drive - which I have now added to my 8296 to make a D machine - is an 8252 (?) which plugs into the IEEE488 internally. Ironically, 8296 had a linear power supply and 8296D a switchmode! So how do the 8296 and the B/P machines relate? Anyone know? Also, how do you do the bank switching to get at the full 96K of RAM? (I think you lose 32K to the screen - very inefficient!) Philip.
