They talked to an analog video monitor in TV or Laser Disc resolutions. The ones we had had two video cards. I think one was a Herc mono compatible for the DOS stuff. I think the one connected to the TGA was analog inputs with seperate sync. Until you activated the TARGA card, the screen was blank. I think in later versions we could load a graphic onto the video card for static display until you loaded the TARGA software. I don't recall the term micro-dots, but everything was anti-aliased. I was the technoid that connected the devices, made them all talk, and cobbled together software for moving the images. I also learned a lot about video production. I think their character cenerators were originally Sony MBC-55s. They then moved to Chimera or something similar. I just remember replacing the ROMs and software on these units all the time for upgrades.

Dr. Hopper's 100 birthday

by Lee.Courtney＠windriver.com

I was lucky enough to have dinner with her when she visited our student ACM chapter in the mid-1970s. Remember her smoking (several) unfiltered Camels that evening. Great speaker. Told a very funny story about being mistaken for a flight attendant (stewardess in those days) when walking thru the airport in her naval uniform.

multiple cpu machines Re: rogues galleries

by mtapley＠swri.edu

Day late and a dollar short.... As Tony Duell said, DEC Rainbow, 2 CPU's, Z-80 + 8088, possibly count the 7220 graphics processor, so 2 or maybe 3 CPU's. (hangs head in shame) Oh yeah! (head comes back up) AlphaServer 2100, 3 CPU cards ... but all three the same Alpha 4/275 CPU. Sigh. NeXT cube, 68040 + DSP56000 + i860 (on NeXTDimension card) .... ... but then it's not supported to get the i860 to do anything but drive graphics, so that doesn't count - back to 2 CPU's. (head hangs again) oh well. -- Mark Tapley, Dwarf Engineer (I haven't cleared my neighborhood) 210-379-4635 Dwarf Phone, 210-522-6025 Office Phone

I have a Co-Co 3 and an Apple][. Using TV's so far, better resolution would be nice. I'm in San Antonio, TX, 78254, and will not be able to pick up a monitor. a) Anybody near Evanston planning to talk to Jack about one of these? b) Anybody in category a) willing to pak/n/ship one for me, for 1.2 * packing and shipping cost or similar? c) any idea what shipping will run? I'm guessing order of $40 or so? -- Mark Tapley, Dwarf Engineer (I haven't cleared my neighborhood) 210-379-4635 Dwarf Phone, 210-522-6025 Office Phone

Cleaning disk packs

Nor are they particularly useful. They are better at contaminating packs than cleaning them. Visual inspection and cleaning is absolutely essential when working with 20+ year old unknown media.

OT: Vintage radio opinion

by cclist＠sydex.com

While going through my dustpile, I came across this communications receiver front end: http://www.sydex.com/images/fe.jpg I vaguely remember picking it up in the 60's on Chicago's S. Michigan Ave. "Radio Row" (as boxed new surplus) and that I hooked it up long enough to determine that the IF output is 1600 KHz (or should I say KC?). It's undoubtedly part of some dual-conversion receiver--I suspect something like a Heathkit, but that's just a guess. Tube lineup is 12AT7, 6CS6 and 6BZ6. My question is if this is something worth selling or if I'm likely to lose my 65 cents eBay listing fee. Any additional information from someone who recognizes this would be welcome. Cheers, Chuck

Followup: Hazeltine "Computer"

by cclist＠sydex.com

Well, I finally got around to prowling through the 5.25" floppy archives for the so-called "Hazeltine" computer diskettes. I found 'em--in the last 10 diskettes in the file(!). In the meantime, I ran across all sorts of names of systems not heard recently, such as "Peoples World" and "Pan Asia". The diskettes contain only the legend "Hazeltine CP/M" and date from about 1982 or so. The bad news is that the boot tracks contain a CP/M system image, along with CBIOS, but no clue is given as to the system name. Looking at the directory, there was a disk utility to format and surface copy, but no identification there either. There was also a copy of Spellguard and Wordstar--aha! Wordstar almost always contains the name of at the least the terminal, if not the system. Well, it does--but the terminal listed is an ADDS Viewpoint--and no system named. :( Bottom line is that I have nothing to contribute to the "Hazeltime Computer" legend--and, with the discovery of the ADDS terminal code, don't even know why the customer insisted on calling it a Hazeltine (but he did--I found the letter in my files. So--shrug! My guess is that the "computer, given the date" may have been housed in the same box as the floppy drives.--and that a Hazeltine terminal was connected to it. But I didn't think that a Hazeltine had cotnrol sequences anything like an ADDS Viewpoint. Cheers, Chuck
