Great progress has been made in running the Lambda firmware and diagnostics. A way has been found to structure things such that the emulator is releasable without infringing on anyone?s copyrights. Now what we need is software tapes, specifically a Lisp distribution tape of any version. If anyone has any tapes in any condition, or knows someone who might have something, please ask them to consider imaging their tapes, or having them imaged. If you have images of anything that aren?t the images already on bitsavers, I would love to hear from you. Even partial or corrupt images are potentially useful.

Full immersion emulation

by charles.unix.pro＠gmail.com

Part of the iconic mainframe experience is the cold room sounds; for early Multics installations (and other systems) the sound of the Selectric operator's console. I/O Selectrics are rare, expensive and unreliable. If some good quality audio clips of a Selectric were available, it should be possible to jimmy up the console terminal emulator to make the sounds. So I am fishing for any existing audio clips with clean sounds, or someone with a Selectric that is willing to make some recordings, or a pointer to somewhere where all of this has been done already. -- Charles

Looking for any information and/or documentation on DATARAM DR-111 (assembly 61101) 16Kx16 core memory boards for the Unibus. I've got four in unknown condition, one with a clearly destroyed 8T37. I have a large format scanner with ADF and can digitize print sets if necessary. Thanks, Jonathan

Looking to re-home some NeXT hardware

we may some parts pieces maybe when we stage our next cube... who knows might pop up and work by it self.. let me know what you are not going to used there. thx Ed# _www.smecc.org_ (http://www.smecc.org) In a message dated 3/8/2017 2:07:11 P.M.

I have the Cube working with dual monitors and have no issues with that one at all.

Oki 3305 disk drives

by wrm＠dW.co.za

Hi all I have a couple of Oki 3305BU 1/3 height 5 1/4" drives. On startup the motor spins and the heads load, but the heads don't move. Also, my BIOS tells me I have a drive failure. On taking them apart for a bit of a lube I noticed they have EPROM 8748s inside. Could this be the problem, EPROMs lost data? This would be a first for me, I have EPROMs from the seventies which are still fine. Anybody familiar with these drives? Thanks W

Fluorescent lights (Was: Full immersion emulation)

by COURYHOUSE＠aol.com

have no idea... wife bought them at home depot they were not cheap but just twisted ino fixture and done. I am going to do dame in some of the rooms at SMECC museum too. I like a simple fix and this was! In a message dated 3/7/2017 12:43:24 P.M.

Ed# > I've asked about those and have no sources of such. They do have to work thru ballasts and deal with starter issues that are no longer relevant, unless you remove and rewire the ballasts / starters out of the old fixtures. The things I've seen are the same form factor as a 4' dual tube dual 40 watt fixture with 110 in and light out. Pull and toss an old dual tube fixture and replace with new LED. But I've not seen the tube solution. I've got a couple of spots the tube thing would be desirable, but no source of such. If you do have a source I'd be interested. thanks Jim

Fluorescent lights (Was: Full immersion emulation)

by COURYHOUSE＠aol.com

we had tubes with LEDs in them... took old florescent tube out of fixture.. twisted in the thing with the LEDs in it that hacked wight into the lighting fixture and done! Ed# In a message dated 3/7/2017 10:23:36 A.M. US Mountain Standard Time, cctalk at classiccmp.org writes: > From: Jon Elson > I have converted our kitchen to LEDs. Yeah, I've already done ours, too. Our fixtures are let into the ceiling, so just replacing them with LED ones wasn't an option; I couldn't find ones that took the same opening. But I bought an under-ceiling fluorescent-sized LED fixture, made by a company called Hampton Bay, to replace an under-ceiling fixture in another room, and I noticed it was just enough smaller than the ones in the kitchen. So I gutted the kitchen fixtures, took Hampton Bay units, discarded the plastic light-shields, and with a bit of trimming, convinced the base plates (which holds the power supply, LEDs, etc) to fit into the existing fixtures. I'm now currently wanting to do my shop, and I'm looking for something which is a bit less work - tubes that I simply plug in, or something like that, are what I'm looking for! Noel

MIPS I-IV instruction set standards

by aap＠papnet.eu

I'm wondering where the MIPS I-IV standards that are referenced everywhere are defined. I was able to actually find what seems to be the IV standard [1] but found no such thing for I-III. I didn't even find any bibliographic references to them. Did they only exist as printed books and nobody bothered to scan them? Or are they under copyright? Would be nice to have them accessible somewhere. [1] http://www.cs.cmu.edu/afs/cs/academic/class/15740-f97/public/doc/mips-isa.p…
