RK05 spindle pulleys - trade 50Hz vs 60Hz?

by mattislind＠gmail.com

Hello! I have two RK05J-AA as part of a system that I guess has been imported used form the US. A DC-10 simulator. The only difference is the pulley, the motor position and a 230 / 115 V jumper inside. Is there anyone in 60Hz land that has the opposite problem and want to trade two spindle pulleys? The good thing for me that I would guess that it possible to use a lathe to get the diameter down to the correct 50Hz diameter. On the other hand going >from 50Hz to 60 Hz is tougher... Then there is a PC05 that has the wrong number of grooves on the motor pulley. Apparently it should be 16 instead of 20. Now in 50Hz land the only difference is that the punch would be slower than it should be. Using a 50Hz punch in 60Hz area might get you into problems, so maybe there is someone here as well that want to do a trade? /Mattis

Strange third party board in PDP-11/45

> From: Paul Birkel > Unfortunately there's not much documentation for the MS11. ??? We're actually pretty well off, there; we have: - MS11 Maintenance Manual (DEC-11-HMSAA-D-D) - MS11 MOS Memory Troubleshooting Guide (DEC-11-HMSTS-A-D) - MS11-B Engineering Drawings About all we're missing are the MS11-A/C data board engineering drawings. (The control board is in the MS11-B prints.) > From: Mattis Lind > This could mean that 16 bit data is in the L chips while the faster > chips are used for a 10 bit cache tag. Sounds plausible. > And of course those two I/O connectors don't belong on a cache. > ... > Those IO connectors are connected to two double height boards in 26 /27 > AB. They are also made by ACT and contain a few TTL chips. If the board is a cache, how does it get filled? It would have to listen to the UNIBUS the memory is on. So I'm guessing that's that those connectors and boards are for. Note that there has to be a signal from FastBus (anyone know the correct capitalization for that?) which tells the CPU if the MS11 has a given address or not (given the way the MS11 can be configured as to size and address), so the cache board could use that line to tell the CPU whether or not the location in question is in the cache.

Landfill?

Is there ANY interest in Courier 56K V.92 modems? Laserjet IIP printers? Parallel port and/or SCSI flatbed scanners? (home office, NOT professional) Oversized PC cases with MANY drive bays? Generic 386? PCs? Is it worth even hauling that kinda stuff to VCF?

SDL and SunOS

by dave＠661.org

How feasable is it to compile and run SDL for SunOS? My main reason for doing this is to play Z-machine games on Sparcstations using Frotz (https://gitlab.com/DavidGriffith/frotz) using the SDL interface to play V6 games. -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

MVME188 backplane jumpers

by bear＠typewritten.org

Does somebody know how to set the IACK and BG backplane jumpers for the MVME188 CPU? Remove them all? Leave them in behind the memory and/or cpu board(s)? Something else? All the documentation I can find are for the normal VME SBCs, which the 188 isn't. Thanks! ok bear. -- until further notice

Looking for Tektronix 4052 R12 Graphics Enhancement ROM Pack and Tektronix 4014 demo files

by mmcgraw74＠gmail.com

I have been recovering dozens of old Tektronix 4050 series tapes and found one with Fast Graphics software for the 4051. This software program jumped into 6800 assembly code and retrieved three bytes per vector from a tape file. Apparently this tape is a duplicate - and it appears that all the files bigger than 1KB have corrupt data. Apparently from the 4014 programmers guide - they had a set of demo picture files including a list with R2-D2. I have found Jos Dreesen's ftp tar file with some 4014 pictures - but I'm looking for an R2-D2 picture file that is on the tape I have but corrupt. I also discovered that Tektronix made a 4052/4054 R12 Graphics Enhancement ROM pack which included the Fast Graphics program in ROM. I would love to find one of those ROM packs - hint/hint :) I did recover one of the shorter picture files of Snoopy - but since I don't have a 4051, I can't run the Fast Graphics program on my 4052 or 4054. One of my buddies threw a C program together to convert the data file into Tek 4050 PRINT statements. I've posted the SNOOPY basic program and screenshots of running it on vcfed in a new thread: http://www.vcfed.org/forum/showthread.php?64726-Tektronix-4051-4052-4052A-4… I'm also still looking for a 4051/4052 Display Board. Mike Haas posted pictures here in Oct 2016 of lots of Tektronix boards including a Display Board - but I don't have any direct contact info for him. Monty

68k development, Avocet Development

by harper＠secureoutcomesinc.com

Greetings to the List - Carlo, I have been using IDE68K out of Norway for about five years and it is excellent: http://home.kpn.nl/pj.fondse/ide68k/ It includes the 68020 instructions such as bit instructions etc - also floating point. I only use the assembler and download S-records to the MVME177-005 boards that I use. I have never found any bugs etc. Best, Jack At 12:46 PM 7/20/2018, Carlo Pisani via cctalk wrote: >hi >does anyone happen to use Avocet Development Tools for m68k? >how good/bad is it? ---------------------------------------------------------------------------------- Jack Harper, President Secure Outcomes Inc 2942 Evergreen Parkway, Suite 300 Evergreen, Colorado 80439 USA 303.670.8375 303.670.3750 (fax) http://www.secureoutcomes.net for Product Info.
