Anytime you see something you have not seen before... it is worthwhile............ ? ed# Sent from my Verizon, Samsung Galaxy smartphone -------- Original message -------- From: Dave Wade <dave.g4ugm at gmail.com> Date: 8/29/16 12:11 (GMT-07:00) To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: CHM Folks, I am going to be in San Francisco in a few weeks' time, but only for about a day and half. I could spare 2 hours at CHM but is it worth dragging myself up there on a Sunday when there are no working exhibits, and I will only have two hours. Dave.

Looking for AT&T WE DSP16A development tools (DOS) and manuals

by jgevaryahu＠gmail.com

Does anyone have a copy of the AT&T/WE DSP16A development tools (assembler, etc) for DOS, and the devkit manual? The actual DSP datasheets and architecture manuals are on bitsavers (oddly, not in the same directory, which was confusing to find): http://bitsavers.trailing-edge.com/pdf/att/dsp/WE_DSP16A_Digital_Signal_Pro… http://bitsavers.trailing-edge.com/pdf/att/dsp/WE_DSP16A_data_sheet_addendu… http://bitsavers.trailing-edge.com/pdf/westernElectric/WE_DSP-16_DSP_Inform… But I'm looking for the actual assembler utility or devkit itself, which are listed (as DSP16A-*) on page 2-3 (pdf page 10) of http://bitsavers.trailing-edge.com/pdf/att/_dataBooks/1995_ATT_Product_Sele… Does anyone have a copy of this, or know someone who has it? -- Jonathan Gevaryahu jgevaryahu at gmail.com jgevaryahu at hotmail.com

cctalk Digest, Vol 26, Issue 29

by anders.k.nelson＠gmail.com

Hey Rob (and anyone else sniffing signals), I've been using a USB logic analyzer from Saleae (https://www.saleae.com/) for years now and the software is really good. Way cheaper than a standalone unit. I'm unsure if the inputs can handle more than 5v but you could throw a divider network in front and try it. Also there's the Digilent Analog Discovery ( https://www.sparkfun.com/products/13929) which does the same stuff but I can't vouch for the software as I've never used it. Inputs can handle +/-20v apparently. =] -- Anders Nelson +1 (517) 775-6129 www.erogear.com > ---------- Forwarded message ---------- > From: Rob Jarratt <robert.jarratt at ntlworld.com> > To: "'Paul Koning'" <paulkoning at comcast.net>, <rob at jarratt.me.uk>, > "'General Discussion: On-Topic and Off-Topic Posts'" < > cctalk at classiccmp.org> > Cc: > Date: Mon, 29 Aug 2016 17:33:56 +0100 > Subject: RE: DEC Pro 350/380 Memory Cards - Interchangeability? > > > > -----Original Message----- > > From: Paul Koning [mailto:paulkoning at comcast.net] > > Sent: 29 August 2016 15:08 > > To: rob at jarratt.me.uk; General Discussion: On-Topic and Off-Topic Posts > > <cctalk at classiccmp.org> > > Subject: Re: DEC Pro 350/380 Memory Cards - Interchangeability? > > > > > > > On Aug 28, 2016, at 5:11 PM, Rob Jarratt <robert.jarratt at ntlworld.com> > > wrote: > > > > > > I have a 350 and 380.

http://www.ebay.ca/itm/201655050108?rmvSB=true I can't believe no one has bid on this! I hope it goes to someone as the complete set, not just for the keyboard! Cindy Croxton

ICS Microprocessor Training Lab info

by starbase89＠gmail.com

Greetings! About a month ago, I picked up a "Portable Microprocessor Training Lab" made by Integrated Computer Systems. This thing is cool! It consists of three boards and a power supply built into a suitcase. The main system board is mounted in the bottom of the case on top of the power supply. It has an 8080a, an 8255, four ROMs and 4K of RAM with room for four more. It has a hex keypad plus function buttons and eight LED character displays. There is a bank of about 12 terminal pins for +5, ground, audio in and out, clock and a few that aren't named. I take it the audio ones are for cassette? It has two ribbon cable connectors on the edge. One is for the 50 pin cable that connects to the I/O board. The other one is especially cool (to me, at least.) It's meant to hook up to an S-100 chassis for expansion! The second board is for I/O. It has two 8255s, an 8253 and room for eight more RAM chips (but no sockets.) It has connections for cassette, RS-232 and teletype. Connected directly on top of the the I/O board is the "Experimental Parts Assembly." It has I/O terminals for analog signal, plus minus 12v and plus 5, optical in/out and motor control/supply/drive. It has a holder for three AA batteries, a motor, a speaker and a thermistor. Finally, it came with the cassette "Self-study Microcomputer Interface Training Course: Program Cassette Library." The big thing I'm missing is documentation. It came with nothing and I can't find much, even with The Google. A system description, a schematic and something explaining what's in the ROM would be nice. I've also got to find a book on 8080 assembly language. Like I'd said, all I have tried to work on so far have been a C64, an Apple IIe and a TI-99/4a with only a basic understanding of BASIC :-) Lately though, I've been feeling like I need more of an intellectual challenge. If anyone can help with more inflammation about this system, documentation and/or any suggestions you may have, I'd welcome it. Thanks in advance! Joe Giliberti

FTGH: More miscellaneous old stuff

by mouse＠Rodents-Montreal.ORG

Okay, I took a bit more time going through my storage. (a) The SparQs are indeed disks; I didn't look closely enough. (b) Some more stuff: - Three disks, which IIRC came out of a MicroVAX-II. Two are Micropolis 1325Ds and the third is a plain 1325. Also present are two sets of cables, each set suitable to connect one drive to a controller card. - One HP 9153A (an HP-IB device; it appears to be a 3.5" floppy drive). - One HP 7958A (an HP-IB device; it appears to be disk). - One HP card, likely the interface card from something like a 7958A. It has an HP-IB connector, an ID switch, two connectors for cables to the drive, and a connector apparently for power. In the etch on the component side is the number 07957-60001; on a sticker, below a barcode, is the text *57CNO14515* (or perhaps *57CN014515*, the font is ambiguous). As before, this stuff is in Ottawa, and is yours for the coming and picking it up. Functionality is unknown, and details may be incorrect because they were hand-copied. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

Imation Travan-1 tapes

by jwest＠classiccmp.org

I have a partial box of new/unopened Travan TR1 tapes (800/400mb) that I have no use for. There are 7 tapes in the box. I'd rather not ship, so my plan is to take it to VCFMW and put on the free table. But iff anyone desperately needs them, make me an offer. J

Docs for DEC MPS Intel 8008 Development System scanned

by j＠ckrubin.us

The MPS (MicroProcessor Series) was an attempt by DEC to introduce an Intel 8008-based system as a cost-effective replacement for minicomputers used in process control. The system has its own 14-bit blinkenlights front panel for accessing the 8008. Docs here: https://www.dropbox.com/sh/bezyixp76x2q3i4/AAAdGzzycbTIys1Ftde2BpR5a?dl=0 I'll leave the docs up for a week or so. Jack
