Old Apple II game manuals and the Internet Archive

by nospam212-cctalk＠yahoo.com

While clear out storage spaces I have come across binders of photocopies of lots of old Apple II game manuals. I've checked online for those that have been scanned already and will toss those. Before I toss the rest which I haven't found online, I'd like to scan them and upload to the Internet Archive to save them. Most of these are one page with a few 2-4 pages. What I'm wondering about is the best way to upload them after scanning. Do each individually, which adds a lot of entries to my small upload page (which I suppose isn't a big deal) or zip them up and upload the one file and make sure the metadata is properly set to identify each manual in the zip. Or some other method? Suggestions? Thanks, David Williams www.trailingedge.com (http://www.trailingedge.com)

SQ703/6 conversion and a little fun

by g4ajq1＠gmail.com

A few months ago, thanks to help from several people here, I converted an SQ703 TMSCP controller to SQ706 MSCP. I had problems trying to use it on the vax due to the complexity of mapping Q-Bus registers under ODT, so put off trying until I got the LSI-11/73 going. Now I have a problem: It seems to run and recognise the controller as SQ706 according to the on-board diagnostics, however it insists saying it is at 777450, the TMSCP address.? Trying to change it gives me an out-of-bounds message. OK, I thought, I will just use it there. Put it in to a running RT11 system and it shows up at 772150 and clashes with an existing controller! It seems that one of the PALs is maybe setting up the address! Anybody else tried this? cheers, Nigel Here's the fun:? https://www(dot)bbc(dot)com/news/entertainment-arts-59089596 Maybe our vax computers will become popular once again! -- Nigel Johnson, MSc., MIEEE, MCSE VE3ID/G4AJQ/VA3MCU Amateur Radio, the origin of the open-source concept!

8" disk drive questions...

by geneb＠deltasoft.com

I'm working with the developer of the Applesauce disk imaging tool in order to iron out some issues with 8" disk support. I'm using a Qumetrak 842 disk drive that's got support for both double and single-sided media. This means that it's equipped with two index hole sensors, slightly offset from one another. It's my understanding that single-sided media has the index hole in one spot on the jacket, and double-sided media has one in a slightly different location. The issue at hand is some NIB Dysan double-sided 8" media I have - the disks have index holes in the jacket in both locations. Is this typical, or do I have some weird "special" disks on my hands? The Applesauce author posits that the combination of the dual-sensor drive and the dual-hole media wouldn't typically find themselves together. Is this accurate? If it's not, how would a system contemporary with the media have handled the two index holes?
