Does anyone know where to find a punched card reader these days? I'm looking for a small desktop unit that I could interface to a PC. I know DEC sold a model CR11, and there were others out there. I remember using some neat little card readers that were stationed here and there on campus at UC Berkeley in the 70's for remote job entry to the CDC-6400 (and if I remember correctly they had a DG Nova underneath). Are there any of these out there, that I could take, borrow, or buy? I'll be starting an IBM 1130 software archiving project later this summer. (I did a google search and about all I found were requests just like this one, from the classiccmp archives. Hmm. And there's one place that'll rent you a desktop reader for $1500/month).

ALL OEMs were offered 3.31. Many did not want to pay the asking price. Compaq and Zenith were the most notable ones who did. There are minor differences in MODE.COM, IO.SYS, FORMAT.COM, and a few other files from one OEM's version to the next. 1.25?, 2.11, and 3.31 are the OEM versions that were most commonly customized, with changes such as support for 720K 5.25", 720K 3.5" (same, but a few messages altered), internal/external video, ... Whenever using 1.25, 2.11, or 3.31, ALWAYS keep track, AND IDENTIFY, which OEM it was. The customizations were different from one OEM to the next. Prior to 5.00, MS-DOS was, IN THEORY, available only from OEMs. Yes, there was such a giant gray market that nobody noticed the restriction. There appears to have been a 10 year non-competition contract between MICROS~1 and IBM, wherein MICROS~1 could sell to OEMs, but could not sell DOS as a retail product. 5.00 was the first version where DOS was available legitimately as a retail product. It was "NEW and IMPROVED!" The "NEW and IMPROVED" consisted mostly of bug fixes to 4.00, plus availability from MICROS~1. NOTE: 5.00 has met the 10 year rule for over a month now. Windoze 3.10 has 2 more months to go, even for BETA. OB_OT: NOT COUNTING bundling of additonal [third party] programs, who can name what the differences are between 5.00 and 6.00? -- Grumpy Ol' Fred cisin(a)xenosoft.com

Thank you The phrase "large disk support" will always carry some confusion due to it's RELATIVE nature. 32M, ~500M, 8G, ... What is the current limit?

Boom cars (ot for sure...)

My first msg hasn't come through yet, so I am resending it.

Cancellation in the >large would obviously require much higher power levels. It is actually more complicated. The dynamics of the room would have to be accounted for, which makes it many times more difficult than in the headset case. Also, to be able to cancel the noise in several directions you need more drivers and mikes. I once toyed with the idea of a feedback-controlled stereo system to completely elliminate the dynamics of your listening room and hear those of the recording hall, for example. The idea was: when you record, you place mikes separated 3-4" apart in one of the audience chairs, mimicking the directionality of human ears mounted on a cranium :-) . In fact, you install several such sets of mikes, all with a slightly different orientation wrt sound source. Then, at home, you put on a headset that doesn't cover your ears, but it has a second set of mikes like the ones used for recording, and some orientation sensing device. The stereo/DSP's job is the following: to project on your headset's mikes sound waves that produce identical local pressure at your ears (feedback control ideas would be used) to those that were received at the recording hall by the set of mikes that most closely matches your current head position. Voila`, Panoramic Sound. The algorithms for doing this exist already, and, while slightly complicated for the ocasional home stereo hobbyist, they are within the grasp of any grad student in the control/DSP/cancellation field. They involve the estimation of the reproduction room's characteristics, feedback control and active cancellation ideas. Somebody must be developing this exact idea somewhere. It is just a logical step given the state of DSP and active cancellation technology. Carlos. -------------------------------------------------------------- Carlos E.

Punched card readers

IIRC (questionable), they used standart V.35-type connectors. But since V.35 is generally a serial interface, and the reader would most likely be parallel, dunno about the pinout... How hard would it be to figure out which lines were input to the card reader (there might be an 'enable' line or something like that)? If it turns out there are no input lines to the reader, then all lines coming out are output, and in the case of the fairly-recent Documation readers, they should be TTL-level signals. Hook up a bank of appropriately-wired LEDs to determine which line are data and which is strobe. Just a thought... -dq

DEC RL02K-DC in Kansas City

by mmcfadden＠cmh.edu

I just came across at the local computer surplus four RL02K-DC disk packs. Non of the shoch-watch indicators were triggered. They have a label about 8650 diagnostics on them. Anybody need them? Mike mmcfadden(a)cmh.edu
