FS: Original Apple II- Upgraded to a II Plus

by slandon110＠gmail.com

The Original II didnt sell at VCF, So I figured id offer it here one last time before sending it off to eBay Its an Original II, however the original owner had it upgraded to a II Plus at one time, so the board's date code is 7/80. It has a II Plus keyboard installed, but it comes with the non operational Original II Keyboard. It has a Disk II Drive with interface card that works great 16k Language Card Thunderclock Plus Clock card It comes with a 9inch B&W RCA Security Monitor in fair shape that works good. The system boots and works. If youd like to see pics let me know $250 dollars plus shipping gives it a home

DEC VAXmate (PC500) power supply H7270B trouble

by iamcamiel＠gmail.com

I'm trying to get my VAXmate working, but the power supply is not running. 300VDC is present, but no secondary voltages. Before I start tracing the board, I'd like to know if anyone has the schematics for this power supply, or maybe some tips on how to proceed. Thanks, Camiel

Sun Microsystems Model/Price Lists? (and Sun 1 research)

Great. Once I had a chance to help out with a restoration I pulled out my notes, files and that "folder for when I ever get access to a Sun 1". That's what ultimately lead to me getting the 2 Sun 1's I now have. I'm finding folks being very friendly and helpful in gathering info... had folks open up a keyboard and take pictures as well as in general going to machines and getting pictures (museums, etc.). I'm building up some very sizable and definitive docs... but the time from the intro of the Sun 1 to the release of the Sun 2 is "light" in terms of info. > I also let Bear know that I recovered all of the Sun Unisoft V7 > distribution for the Sun 1 off > of cartridge tape with the exception of one block in the /usr tarball > inside of > /usr/bin/lex.

(bear and I chat fairly often, since he and I work at the same company.... ) Did you happen to find any install instructions with the Unisoft V7? BTW, I have an original Sun 1 CPU board, so I'm excited to hear this...I was wondering where I'd get the early OS for that... (and both of my Sun 1's boot...and got two good HD units... so have a place to "play"). Do you have any of the < 1.0 Sun OS images in queue? I was hoping to have some options as well.. (BTW, I've also spoken to Skeezics about your recovery of PERQ SW... and let me also pass along another THANK YOU for your efforts... it's terrific... what you recovered nicely overlaps with the floppies I just sent him... and will be helpful with the working PERQ 1 that I'm slowly shipping to him, piece at a time...) FYI, I have a working Sun 1, Sun 2, Sun 3 and the original 4/110 now, so any early software I've got great places to demo it Earl

Sun NVRAM battery hackery - later models

by jplist2008＠kiwigeek.com

I have a quadruplet of U5s that has one working NVRAM between them. I pulled one open to see if I could employ the battery modification that has been used by others (several on this list, no less)... but the U5 appears to have quite a different NVRAM module. The earlier ones that I've seen modification pictures of have the 'backpack' battery/xtal, and just a potted nub that requires scraping open to provide access to the battery contacts. The U5 NVRAMs are fully encased in a plastic housing that appears to be epoxy bonded onto the IC/battery/xtal. Are these also modifyable, or should I suck it up and pay $15 a NVRAM at Mouser? Thanks; - JP

Problematic spade lug in power supply

by jnc＠mercury.lcs.mit.edu

> From: Paul Koning > You can of course grab a handy caliper or micrometer and measure it... According to my vernier calipers, 3.9mm (including insulation - the only short stretch without is near the tips of the diodes, and I'd have to disassemble the P/S to get to it). Powered it on with 3 MLM's (3A total draw), and it ran fine; left it running for an hour or so, and the problem connector was dead cool at the end. Noel PS: Odd factoid about MLM's (M7556) - they can be plugged into both the QBUS _and_ UNIBUS (SPC slots only)! Probably the only card that's true of...
