ISO: Tektronix 4404 peripherals

by derschjo＠gmail.com

Hi all -- I'm working on fixing up a Tektronix 4404 workstation (runs Smalltalk-80!).? Or rather, I'm trying to collect the needed parts to assemble a complete system so that I might fix up said system -- at the moment I have only the main CPU unit (but hey, it's a good starting point).? I am looking for: - Keyboard (Tektronix P/N 119-1872-00) - Mouse (Logitech P7-3F-TX-19-1808-00).? This is likely a standard 3-button quadrature mouse but if I can find the exact match, so much the better... - Mass Storage (Tektronix model 4944, possibly others?? This is a SCSI device containing a hard drive on a SCSI->MFM bridge and 5.25" floppy drive on a custom SCSI->floppy interface.) If anyone happens to have spares or knows anyone who might, please let me know.? Thanks as always! - Josh

So, all this talk about panels made me making an oak frame for an IBM panel I had lingering around in the attic for a while. Still need to make a back panel to close it tough. http://bit.ly/2HI2cHC The cables were already cut when I got it. Ed -- Ik email, dus ik besta.

Searching for Sun2 and Sun3 bits and bobs- a long-running project approaches completion!

by ian.finder＠gmail.com

Hi folks, I recently, on a trip to Oregon, finally got a compatible ECL monitor for my Sun 2. It came with a rather nice Sun 3/260, which I?d like to run as well. So I thought I?d put out a beg here- I?m so close to finishing this. I need to shake loose a keyboard and mouse for a Sun 2. Would anyone be willing to sell me one? I?m not expecting a handout; they would be paid for and well loved. On a related note, I?d love to run the 3/260 as well: What I?d like to do for that is hunt down a Sun color framebuffer for it so I can use a more common display. (and of course, enjoy the wonders of color). I?m not sure what the options there are, but I have a nice scan converter so just about any compatible color framebuffer will do. I can then totally repurpose the monitor I?ve just found for my 2/120. So, in the words of another immortal list member, ?advice hints ????? Thanks in advance, - I

WTB Intel 7110 Bubble Memory Subsystem or Chipset

by nf6x＠nf6x.net

I'm about to acquire a couple of 1980s-vintage military surplus AN/UGC-137A terminals (i.e., glass TTYs with some local message preparation and storage capabilities) which have a bubble memory subsystem. They use plug-in cartridges containing 256 kbytes of storage in the form of two Intel 7110 1 Mbit bubble memory chips and their 7242 formatter/sense amplifiers. One of the cartridges contains the one and only copy of the terminals' firmware, which I believe they need to load up at each reboot. Naturally, extracting the contents of that irreplaceable cartridge for archival, and potential future emulation, is going to be a very high priority for me. I have a few different approaches in mind for accomplishing that. One approach would be to remove the two memory devices from the critical cartridge in order to dump their contents in an independent bubble memory subsystem. With that in mind, I'd like to get my hands on a working Intel 7110 bubble memory subsystem, or the parts to build one myself (i.e., a complete 7110/7220/7230/7242/7250/7254 chipset that I could make a board around). Might anybody here have what I need available for sale or trade? I might be able to use some arbitrary old computer or other device that has a subsystem based around the Intel 7110, or a development kit such as the Intel BPK-72, or a chipset to make my own board. If I can't acquire or make the hardware to dump the memory chips outside of their native system, then I think my next option would be to passively snoop the host bus interface of the Intel 7220 controller I expect to find inside the terminals as they perform their initial firmware load, so that I can reconstruct the cartridge contents from the trace data. The terminals were made by the Librascope division of Singer, and brochures can be found here: http://www.librascopememories.com/Librascope_Memories/Product_Literature_fi… http://www.librascopememories.com/Librascope_Memories/Product_Literature_fi… http://www.librascopememories.com/Librascope_Memories/Product_Literature_fi… I already have the critical cartridge in hand, and I posted some pictures of it on Twitter: https://twitter.com/nf6x/status/964578291767173120 -- Mark J.

Canon BX-1 (1977) Manuals

by osi.superboard＠gmail.com

Recently, I?ve started working on a Canon BX-1 machine dated 1977. It was CANON's first standalone business / home computer featuring I guess the Motorola MC6809 CPU, one line of gas plasma display a thermal printer and 125k floppy drive. See pictures here: https://drive.google.com/open?id=1rT4qwtiR68AN5DRqoCwjxGDJvRRdlHha In working condition but without manuals or disks. Only little can be found for this machine, its not listed in http://www.bitsavers.org/pdf/ nor https://amaus.net/static/S100/ Also http://archive.computerhistory.org/ isn't mentioning the machine. So I would be happy, if anyone can help in disk images or manual scans (manual front pages are shown in the picture link above) regards Thomas Known CANON BX-1 Disk/Documents Disks: MCX OPERATING SYS. STANDARD BASIC AND BOOT MCX SYSTEM DISK MCX EXTEND BASIC BOOT.

Alpine vs mutt?
