It is in Tiny Basic syntax so a lot of the commands are abreviated ( you know, things like G. for goto and such ). I also have a document file for it with instructions. One can figure it out without the instructions though. Anyone want it, send me you email address and I'll send a copy to you. Dwight

TI-980

by CPUMECH＠aol.com

Dataterm used to work on the silent 700's, 725,735,745,703,707's.I think that's about all of the terminals. They still do 810,825,880"s dot matrix.

TDL ZApple monitor

by rcini＠optonline.net

All: Does anyone have a copy of the Technical Design Labs "ZApple" monitor program for the TDL ZPU Z80-based CPU card in electronic form? I have the printed source code but I thought I'd ask before scanning/OCRing. Thanks.

TI-74 manual

by b.taylor71＠ntlworld.com

Hello, Were you successful in obtaining a copy of the TI-74 User Manual in .PDF? I have recently purchased a ti-74 that has only the Programming manual and would dearly love to have a copy if at all possible. Thank You, Yours sincerely, Brian Taylor

Speaking of 6502s, was Re: 70's micros still available -

Holger Veit <holger.veit at ais.fraunhofer.de> wrote: These times are gone - assembler is irrelevant for larger projects, and controller have become large enough to allow wasting space and tolerate inefficient code. Some controllers, including the rather lousy 8051 series, still persist, but mainly because "system designers" have used and understood them for 20 years now and it is too expensive to train them another horse. Holger -------------------------------- I have to quibble a bit about this. "System Designers" have to design to cost goals, as well as schedules. Most of them that I have worked with would love to change and have the challenge of a new processor. Training is not a factor. It's the pointy hair managers that want the cheapest processor they can get. And using an old war horse means not having to buy new development tools, SDKs, etc. Plus there is a huge pool of existing applications and coding to draw on. Moving to a new processor can add 18 months extra on a typical program. That's a price few companies can afford. And, of course, the leverage of buying bigger quantities of the old device can lead to sizeable cost reductions. So old core processors tend become embedded (pun intended) within companies. It takes a significant new bauble to break through. The last major change I saw in embedded processors was the ARM chip sets. They were slow to get accepted but now are everywhere. Probably another 10-15 years of life there. And of course the PIC devices are so cheap that they HAD to be utilized. I don't see anything out there now that would be so superior as to be worth the cost of change. Billy

New 11/24, what to do first? More info.

>Contacts or loosen screws can fly through the BA-box in case of your 11/24 > during transport and can provoke short circuits while powering up. >Always inspect your machine carefully, watch out for loosen parts and check >the configuration of your system BEFORE aplying power to it. Don't worry, Pierre, I did all that as soon as I got it home, well before plugging it in. But thanks for the reminder. I have now inventoried the cards and have the following: 1 M7133 KDF11-UA 11/24 CPU with line clock and 2 SLU 1 M7134 KT-24 Unibus map, extension to 22 bits 1 M8743 (ECC RAM, either 512 Kb or 1 Mbyte) 2 M8722 (ECC Memory either 128 Kb or 256 Kb each) 1 M8188 FPF11 floating point processor 1 M7762 RL11 disk controller RL01/02 1 M7258 LP11 printer controller 1 DSD A2130-6 <---------- (what is this? Floppy controller?) 4 M7819 DZ11-A eight RS232 ports each 1 M920 Unibus connector 1 M7297 RH11 MASSBUS Parity Control 1 M7296 RH11 MASSBUS Control & Status Registers 1 M7295 RH11A MASSBUS Bus Controller 1 M7294 RH11 MASSBUS Data Buffer and Control 3 M5904 RH11 MASSBUS Control Transceivers 1 M9300 Unibus terminator 1 M9312 Bootstrap Terminator According to the PDP11 Bus Handbook the Massbus is for transferring blocks of data at high speed (between mass storage devices like disks or tapes?) When I flip the BOOT switch the front panel RUN light comes on briefly and goes out again. Similar behavior to the 11/23+ when it enters ODT mode. There is a green LED on each MOS memory board which is lit, and a row of three (status?) LED's on the CPU, the rearmost staying lit and the other two dark. Time to RTFM I guess :) but I'll bet I can hook up a terminal to the SLU on the CPU board and have it talk to me! I wonder, since there is an RL controller card, -Charles

Basic Language Star Trek Program

The first, by Dr. Li Chen Wang, who wrote PATB itself, was published in the Peoples Computer Company journal in the summer of 1976; it's an adaptation of Lynn Cochran's version for the Altair 8800. That, and an slightly smaller version which Bruce Sherry adapted from the PCC listing, are both on my webpage, along with lots of other versions. http://www.dunnington.u-net.com/public/startrek/ -- Pete Peter Turnbull Network Manager University of York

New 11/24, what to do first? More info (cont'd)

Yes, the RL11, RLV11, and RLV12 will all handle both RL01 and RL02 drives. XXDP won't care whether you boot it on a QBus or a Unibus system, though all but the oldest versions can tell the difference. -- Pete Peter Turnbull Network Manager University of York
