I tried a google search, but alas... :-) I'm looking for the documentation for the olde TI analog sound chip; this dates back to the late 70's early 80's if my memory serves me correctly. I don't even remember the part number. AFAIK, it had some kind of "I2L" (I squared el) technology or somesuch, and it was mostly analog, with some digital control (but nothing like a DSP or midi). Anyone recall this chip? Anyone have the datasheet for it online or willing to scan it in? Background: I remember playing with it a *long* time ago, and wanted to model it in software :-) Cheers, and thanks in advance, -RK -- Looking for Digital Equipment Corp.

RS232 or Parallel port based keyboards and joysticks

by dwightk.elvey＠amd.com

Hi I usually use my laptop as a RS232 terminal. With a little software, you can even emulate a parallel keyboard >from the printer port. Joysticks are a completely different issue. Some Joysticks are digital while others are analog. Most that I know of don't connect to RS232.

Epson QX-10 CP/M disks and Operation Manual

by roger161uk＠yahoo.co.uk

Dear ClassicCmp Readers, I apologise for my joining the list and posting straight away, however, my reasons for doing so are that I have an original set of Epson QX-10 CP/M disks and a QX-10 Operation Manual that is looking for a new home. Unfortunately, I consigned a perfectly working (albeit "screen-burnt" with ash-filled keyboard) example of a QX-10 to the local dump a few years back. More recently, however, while clearing out my office I came across the virtually unused Operation Manual and CP/M disks. The disks are as follows (5 disks in total): Epson MultiFonts CP/M v2.2 & MultiFonts BASIC v1.3 Epson Diagnostic Program v0305 Epson CP/M PLUS Programmers Disk Epson CP/M PLUS Utilities Disk Epson CP/M PLUS GSX Disk If there is anybody who would like these disks and manual to complement a collection or museum of sorts, please could you contact me as soon as possible. Best regards Roger __________________________________________________ Do You Yahoo!? Everything you'll ever need on one web page >from News and Sport to Email and Music Charts http://uk.my.yahoo.com

System/23 Support Disks

by cb＠mythtech.net

Does anyone have a set of the IBM System/23 support disks that came with a System/23? I have a manual here (Volume 1, Learning to use System/23), and it makes reference to disks that came with the manual. The disks are: Customer Support Functions (VOL002) Learning Diskette (VOL003) There may be other disks that go with later manuals (there are 7 manuals total, and I know one of them deals with BASIC, so I would guess there are disks to go with that as well... I would check but I can't get to the other manuals right now). If anyone has these, would they be willing to make me copies if I supplied the blank 8" disks, postage, and a few bucks for the effort? The copies that go with my manuals appear to be MIA (I suspect they were used as blank disks many years ago). TIA -chris <http://www.mythtech.net>

Hi, I got an unknown MCA card that has a sticky tape saying "Streaming Tape Adapter". Since I dont own a MCA system, its free for postage from NY / 11553. I thought it might have been an IMSB017 PS/2 MCA Transputer board >from the description....

I don't need to add much to what Tony has said, except to confirm that what you have is indeed (from the model number) a USA Model B. Other (minor) differences are things like it accepts American spellings for BASIC keywords ("color" vs "colour"), and IIRC some of the screen modes have different numbers of lines. I guess I should go and look up the technical notes for you... -- Pete Peter Turnbull Network Manager University of York

free: two RL01 drives, PDP-11/23, rack

by jrengdahl＠hotmail.com

Here is what is available: - two RL01 drives. I grabbed these to save them from the dumpster, but I have no way to try them out. - two PDP-11/03 (BA11) chassis. One is missing a piece of card guide, but it can be stuffed with 11/23 boards and it will run. If you want an 11/23 board set (KDF11-A, 256K RAM, serial/LTC) I'll throw those in too. The card cage is missing from the second BA11, but the power supply, front panel, and fans are there and functional. - a 39 inch high ugly gray 19" rack that will hold the above. - 14 RL01 disk packs. Some are labelled "RT-11 V5 + TSX", "RT-11 archive", and "Fortran". The RL01 stuff was all pulled out of an unheated U-store-it, and I don't know how long it had been there. I don't much about cleaning heads and disk packs, but I would recommend getting some expert advice and checking things carefully before spinning these up. The drives are missing the mounting hardware (slide-out rails, etc.), and the cable from the controller to the first drive. I have a cable to go from the first to the second drive, and the terminator. Free to whoever will come take it away. Located in Chardon, OH, about an hour east of Cleveland. It will *not* be trashed. It doesn't take up much room, so rather than doing a lot of work to pack it for shipment, I'd rather let it sit until someone can come pick it up. -- Jonathan Engdahl http://users.safeaccess.com/engdahl/pdp-11.htm "The things which are seen are temporary, but the things which are not seen are eternal."
