Teleterminal "Fly Reader 232" Switch settings needed

by bill_r＠inetnebr.com

Does anyone happen to have the switch settings for a "Teleterminal FlyReader 232" tape reader? The one I have works at 1200-N-8-1, but I'd like to know if I can set it to 9600 so it's the same speed as the other serial stuff I've got hooked up to my IMSAI. -Bill Richman (bill_r(a)inetnebr.com) Web Page: http://incolor.inetnebr.com/bill_r Home of the COSMAC Elf Microcomputer Simulator, Fun with Molten Metal, Orphaned Robots, and Technological Oddities.

need the use of a scanner with sheet feeder (near Seattle if possible)

I don't know what Al does, but CDC manuals have "taint", a small piece of paper that forms the outside edge of that center, long-oval-shaped hole. The taint gets torn by sheet feeders... so if you want to return them in the same condition as you borrwed them, I'd have to recommend against the sheet feeder. :(

Need help with Jumpering Imsai SIO board

by caprio＠dcms.com

I have an Imsai SIO Rev 3 serial card. I have the docs but the last section of the manual may be missing. I've read the section on how to set the two jumpers for the baord address but I'm having trouble translating. Could someone who knows this subject please help me to figure out the address of this SIO card? Jumps on the baord are set like this: C7 (port Select 1) 1 16 2 ---- 15 3 14 4 ---- 13 5 12 6 ---- 11 7 ---- 10 8 9 D6 (port Select 0) 1 16 2 15 3 16 4 13 5 ---- 12 6 11 7 10 8 ---- 9 Here is the s-ction out of the manual: C7 A7 --+---------- 1 16 ------+---------| |___|>o--- 2 15 ______| | A6 --+---------- 3 14 ------+---------| |___|>o--- 4 13 ______| | A5 --+---------- 5 12 ------+---------| |___|>o--- 6 11 ______| | A4 --+---------- 7 10 ------+---------| |___|>o--- 8 9 ______| |---) | )o------- --- 1 16 ------+---------|---) --- 2 15 ______| | --- 3 14 ------+---------| --- 4 13 ______| | I/O --- 5 12 ------+---------| MM --- 6 11 ______| | MM --- 7 10 ------+---------| I/O --- 8 9 ______| | D6 OK, so I know that A7=0, A6=0, A5=0 and A4=1, It's not Memmory mapped IO so jumpers go on pins 5 and 6. So where are A3-A0, on D6?. I think the address is: A7 0 A6 0 A5 0 A4 1 A3? 0 A2? 0 A1? 1 A0? 1 and the answer is 013H ???? "The board address is selected by jumpers or a DIP switch in locattion C7 and D6. There are two cases for which this board may be jumpered: 1) to respond to Input/output instructions and 2) to respond to memory access instructions. The case of input/output instructions will be treated first. In selection location D6 pins 8 and 9 must be jumpered together and pins 5 and 12 must be jumbered together. The user must jumper socket C7 so when the desired I/O Port address appeas on the address lines, the inputs to the NAND gate from bits A4 through a7 are high. If, for instance, address bit 6 is desired to be a 0 when the board responds, then pins 4 and and 13 would be jumpered together. If address bit A6 was desired to be 1, then either pins 3 and 14 may be jumpered together or 3 and 13 may be jumpered together, since 13 and 14 are tied to the common address selection input. It is suggested, however, that when jumpers are being used, pins 3 and 13 be connected together to provide a easy visual indication of whether the address bit is a 1 or 0 since that will correspond to whether jumpers are slanted or straight across the jumper socket." ... Thanks for the help.

Need Micro/RSX and PDP-11/53 help

by doc＠mdrconsult.com

Continuing saga of Friday nights haul: When I emailed Terry that I'd pick up the MicroVAX, and we made the arrangements, he told me, "By the way, as long as you haul off that rack, you're welcome to take the PDP-11 and the PDP-8." Naturally, I made that further concession.... The PDP-8/A is in pretty sorry shape, at first glance. It's on hold till I have time to go over it and figure out what's there and what it needs. Probably a couple of weeks. Anyway. the 11/53 is in good shape, inspected, cleaned, and back together. It has Micro/RSX installed on DU0, and not only is it Greek to me, but I've been Googling for 3 hours, and haven't found a coherent description or command reference. Moreover, I don't see any software at all available to run on Micro/RSX. Are RSX-11 utilities binary-compatible? Any suggestions as to a next step? Pointers at the Micro/RSX Users' Group would be handy. Doc

The airport in New Orleans confiscated (yes, took away and kept, never to return) a mini stapler my father had in his laptop bag. This is one of those staplers that is about an inch long, holds 20 staples of that super mini, can't staple thru more than two sheets of paper, size. This was back in November, so everyone was a bit more paranoid. But he showed them it was just a stapler... and they still took it away as a "weapon".

Fw: Route 128 book

by geoff＠pkworks.com

This afternoon, while copying IBM 1620 manuals for Al Kossow's Bitsavers Project, I met Mr. Alan Earls. He is writing a book on Rt 128, as he explains below, and is looking for information. I have invited him to visit both the Rhode Island Computer Museum ( www.osfn.org/ricm ) and the RetroComputing Society of Rhode Island ( www.osfn.org/rcs ), and promised to forward his request for information to friends and colleagues. If you can help the fellow, either directly or by reference, please contact him. Clearly, any tech history writer looking for information on Clevite has done his homework! -----Original Message----- From: Alan Earls <alanearls(a)attbi.com> To: geoff(a)pkworks.com <geoff(a)pkworks.com> Date: Saturday, April 06, 2002 4:48 PM Subject: RE: Route 128 book Geoff, Nice to meet you and chat about "oldies" (Mailboxes, Etc. in Franklin). As I mentioned I'm finishing up (by May 1) a photo/history book about Route 128 and environs in Mass. from roughly the end of WW2 until the early 90s. This isn't a scholarly effort. Rather it is an attempt to provide a popular book that will capture representative images of the "dawn" of high tech -- the post war years with the expanded defense budgets and new electronic technology --- through to the recent past. I'm still trying to locate photos of people, places, and things associated with DG, Prime, Wang and many other companies. I would also love photos from the Multics project at MIT and some photos of the early area semiconductor companies: Clevite, Sylvania, Transitron, etc. Any suggestions would be greatly appreciated. Sincerely, Alan Earls 508 528 6930 PLEASE NOTE: Effective immediately, my email address is alanearls(a)attbi.com. Please be sure you update your files. Mail addressed to my "mediaone" address will no longer be delivered after Mar. 15, 2002.

Lisa 2 Video Problem

by jrice＠texoma.net

Has anyone ever repaired a Lisa 2 with the following symptoms: A distorted video image on the upper 1/3 of the screen? I'm the high bidder on a Lisa 2 on ebay url: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2013387255&r=0&t=0&showT… If you look at the screen shots, the video screen is distorted very similar to what my compact macs do with cold solder joints on the analog board. I figure that it's either a similar problem, dirty contacts or bad caps on the board. Just wondering if anyone has seen similar symptoms. I think I can get a Lisa video board from a friend in DFW who has a cache of Lisa's in storage. The guy's Apple collection is awesome. He has several of absolutely every product Apple ever made including a lot of prototype stuff that was never publicly released. I usually don't attempt board level repair, but for a Lisa, I'll make an exception. I thought Tony might have done one before. Have you ever seen this one before Tony? I think a Lisa would fit in perfectly with my NeXT's, Sun's, Indy and BeBox. Thanks, James You mean you're supposed to read the manual first?

recreating the PDP-11

by pat＠cart-server.purdueriots.com

In a project I'm thinking about starting this summer, I want to try and re-create a PDP-11 (or maybe a -8 or something) using either SSI logic and/or PAL/GALs. I would like to do the entire thing in SSI, but I fear that I'd quickly eat up a lot of money on the project, so where necessary I'd replace sections with PALs. Anyone have any good ideas? About what I'm doing: Trying to replicate an 'old-computer feel' for a mock airport that a friend of mine is thinking about making. I'll have a good amount of time to work on designing it before I start laying down copper on a circuit board. I'd like to make something that 1) looks authentically old and 2) has a design I can (semi-legally, not for resale) copy so I don't have to do all the re-design work myself. I've considered just using a plain-old Apple //e that I have, but that wouldn't be 'old enough' looking I was thinking. It'll need to have a good amount of I/O, and be easy enough that I can actually build it and understand how to program it without much effort. By that way, I don't care about using 'standard OS's' or 'standard hardware' too much, I just want to put together a system with a CPU, serial port, and some sort of floppy drive interface (I prefer 5-1/4 disks at some PC readable format) it can boot off of - or perhaps an IDE interface as that would be easy to program a 'driver' for (or so I'm told). Does anyone have any suggestions for what I should try to build? Eg. what model PDP-11 cpu card, what prints I should get to try and assemble a basic working system, etc. Should I try something else? I would like to go a bit overboard, the look is a part of the thing, but I don't want to screw with finding things like QBUS drivers, and don't think I'll want to bother with a 'traditional mini-computer bus' if I don't need to. This is what I have so far: 1) CPU card 2) Memory - SRAM 3) Front-panel switches 4) Console serial port 5) A few digital I/O ports 6) Floppy interface (anyone suggest an easy to interface controller?) 7) IDE controller -- Pat

ADM3a Keyboard Photo Needed

by bill_r＠inetnebr.com

Just dusted off an ADM3a, and it's intact except for a key centered between the arrow keys on the right-hand side, which is missing the top. I'm also not certain that all of the other keys are in the right positions. Can someone take a couple of close-up digital photos of the keyboard and e-mail them to me? Or maybe scan a manual page that shows the keyboard layout? I may try to modify a spare PC keyboard keytop to replace the missing one, if the colors are close (or I can paint it to match).

the answer is yes, the question is how or why? :) I picked one up out of a stack of indigo 2's thinking that someone was just being funny sticking r10k badges on the teal box, but it actually is! I was under the impression that this machine wasnt made. Let me know if you know otherwise, I'll have more info whenever I boot it up and hook it up to a monitor. It has a floptical drive too! ;) I still have that chrp prototype machine from motorola if anyone is interested. Thanks, jon

by doc＠mdrconsult.com

The previously-mentioned VAX came with this board. AW-20-859-2 TFC-925 QBUS/GCR Tape Controller Much to my disappointment, it seems to be a 9-track tape controller instead of a SCSI interface. No cables, just the board. If anybody has more detailed info, I'd like to know. If it's really not a SCSI controller, I don't plan to have a 9-track anytime soon.

They're not normally used for fasteners, which is what the others are for (arguably with the exception of BSP) :-) Yes, they're usually fairly coarse, and used for things like leadscrews on machine tools and vise jaws. For leadscrews, they're usually made to some specific pitch that equates to some nice decimal number of turns per inch, or millimetres per turn. They're also unusual in having large flats on both the crests and troughs (most other threads are rounded on one or the other); in fact they're almost square -- the thread depth is 0.5 x the pitch, and the walls slope at only 14.5 degrees, so the included angle is 29 degree, much less than most threads which are typically either 55 or 60 degrees.
