For those of you who aren't reading at home, these mnemonics mean: SPIM: Space immediate (1-3 lines) SKIP: Skip immediate (to carriage control channel) SKAP: Skip after printing (carriage control) SPAP: Space after printing (1-3 lines) All of these were control instructions that referenced the printer (unit #9). The carriage control tape was a standard 12 channel one (IBM used them on LOTS of printers like 407's and 1403's). You could access any one of the 12 channels. The 1620 had two indicators for "summary line" (channel 9) and "end of printable page" (channel 12), which if you have a hard copy impact printer are probably still there. Yes, if you skipped to a channel that WASN'T punched, you fed lots of paper, which is why (if you were smart) you punched the unused channels on the same line as the "end of paper" channel (12). Oh, standard Fortran: blank, single space; 1, top of form; 0, double space; +, overprint (not supported everywhere). Feel free to consult your friendly Unix man page for the program 'asa' for further reference. One of these days I'll dig out the computer pic I made back in the late 60's using a video camera connected to an 1130. 16 levels of gray, and 200x160 or so resolution. Cool for the day!

Mona Lisa

The one I > remember had > 3 or 4 printouts taped together. Have any of the card decks survived? I don't have it in Fortran nor for IBM but I think I have a deck of cards for my ICT 1301 which produces a two or three page printout, printing across the perforations. At the moment, I don't have a 100% working card reader and I'm in the process of selling my spare 1301 so all my 'spare' time is used up trying to put back together a 5 ton jig- saw I dismantled over 30 years ago. At least I have an assembled one for reference but I keep finding differences between the two machines, one being the first one to leave the factory and the other probably being one of the last. I hope to make all my 1301 software, including the Mona Lisa, Snoopy, the lady on a stool etc available online sometime together with some of my many manuals and a simulator which will run on a Mac. Will need to find someone to host the archive in perpituity, maybe BitSavers would be willing to do it, but I haven't got the data off the Ampex ten track tapes yet.

looking for racks

by rescue＠hawkmountain.net

A friend is looking for 6 computer racks. He is looking for ones with "high ventilation (mesh doors, etc) and locking is a requirement". Anyone got anything like this in the MA/RI/NH area (or possibly local enough that can ship (at an affordable rate) via freight) ? If you don't have 6 then let me know what you have, and I'll pass it along with your contact info. -- Curt

Anyone know of a 1970s-style dot matrix "computer photo" generator/converter?

by ethan.dicks＠usap.gov

Hi, All, I'm sure many of us remember the "computer photo" craze of the late 1970s - go to a mall, get your photo taken by a computer, then buy one of a number of trinkets (calendars, coffee mugs, etc.) with your photo rendered by dot matrix... an old family friend even had one of those rigs - driven by an Ohio Scientific Challenger III (a machine I've long lusted after). There must be a way to simulate that look today - some sort of GIMP filter or web app or something. I've been googling around for "ASCII art" and "dot matrix photo", etc., and have found some interesting stuff (http://blog.modernmechanix.com/2006/07/27/ascii-art-1939/) but not what I'm looking for. Ultimately, I just want to take a snapshot of me and filter it to resemble that 1970s "computer photo" look. Any suggestions where to turn? Discussions of how it was done and how it could be done with vintage hardware now are interesting and probably on-topic, but not the goal of my question.

AmproLB+ SCSI...

Your suffering from PCism, you expect it to work like a PC and it will not. I'm using a 45MB fujitsu 3.5" scsi drive That was given to me and a modified version of the ampro scsi bios. The base SCSI software supports a limited number of drives and SCSI to MFM bridges that were available in the mid to late 80s. Those would be the Xebec and Adaptec and one seagate drive all in the 10-30mb size range. Add to that at the time the AmproLB+ software was written SCSI nee SASI was still somewhat developmental. Yes, I had to take the Ampro sources and rework them a bit for that drive and debug them. The basic code is online in one of the repository sites and it's well done so modifying it should be resonable. I'll admit it's been 17 years since I did it and it's running so I haven't looked at it in a long while. Hope that helps.

Vinyl Data- Classic Computers / Indie music tricks crossover

by tpeters＠mixcom.com

http://www.kempa.com/wp/2004/03/09/vinyl-data/ Excerpt: One strategy that major record companies have been employing lately to deter downloading is adding bonus computer content to new CD releases. I recently discovered that this technique is not unique to CD?s, but had in fact been practiced in the vinyl era as well. That?s right: there were a handful of records released in the late 70?s and early 80?s that contained computer programs as part of the audio. This is totally insane, and totally great. Most of these programs were written for the Sinclair Spectrum home computer series. The Sinclair Spectrum was a relatively cheap home computer system that used a television set as a monitor and loaded programs from tapes. It thrived in England in the early 80?s: ----- 240.
