One volunteer needed, special mission
by Evan Koblentz 29 Nov '18

29 Nov '18

I'd like one person to come tomorrow afternoon, help me finish Festivus setup, and then we'll sort books the rest of the night. VCF will cover your overnight fee and you'd get first dibs at the massive surplus pile.

Orig Mac disk drive does not stop/bangs head
by Herb Johnson 29 Nov '18

29 Nov '18

> when I power on my orig MAC the drive races to the > front and attempts to keep going... is there a fix? My guess is, this is a Macintosh 128K and "the drive" is the 400K floppy drive. "the fix" is to diagnose the problem. Try another 400K floppy drive externally, or a 800K external floppy drive - see if they work the same way. If so, you may have some kind of 68000 processor motherboard problem. Or a loose internal floppy cable. If external drives work, then see what's going on with that internal drive. Maybe the track 00 sensor is bad or its little cable isn't connected well. Or the head stepper has lost a phase and is running backwards (desperately seeking track 00 while running to track 99). "The Dead Mac Scrolls" suggests if the screen is dark and you have odd behavior, you may need to fix/replace the analog card, specifically the flyback transformer. But you'd likely report a dark screen, so that's not likely the problem. The book doesn't seem to list your floppy drive problem. Herb -- Herbert R.

Festivus setup
by Evan Koblentz 28 Nov '18

28 Nov '18

I was at the museum from 1pm to 5pm today mostly doing warehouse stuff. Dan J. helped set up for Festivus at 8pm after the InfoAge staff meeting. We moved some furniture out of the room that we use for videogames. Dan left, and then Jeff B. came over at 9pm. We set up most of the tables and moved a bunch of party supplies into place. We were there until 11:30pm. I'm going to be there early Saturday to finish. Tony said he'll be over around 9:30am, but I am hoping to get one or two helpers earlier than that (8:30am). Any volunteers?

Intro
by dillera＠gmail.com 28 Nov '18

28 Nov '18

Hello- I've been asked for an intro, so here we are. I live in Philly and work for a very large local MSO in the city. I run a medium sized engineering team and we handle large scale messaging (SMS and Email) for the MSO. I've been to a number of VCF East Festivals and have loved them (the Ted Nelson festival and the recent Apollo 11). I have been aware of the forums and site for many years, but just decided to join the list. Like many here I have a decent collection of computers - enough that I have to pay for a storage at a local provider (climate controlled of course, I'm not a monster...). I've been lately interested in 1990s era workstations and have been working on refining my collection. I both love and hate eBay. My collection ranges from Cannon Cats to Atari 800XLs to SGI Indigos and much in-between. Looking forward to meeting some of you as time and life permits, meanwhile we can do it virtually. -andy diller PS - To give you a better idea, here is my basement space with my 'in-progress' work right here as I type this: Currently working on: netbooting my SGI and Ultra10, setting up an open-source asset-management app with tags so I can track things better (that's the hand-held scanner there in front of the Sun) and installing Netatalk service on a linux machine to host a AppleTalk/Ethertalk file server for some older Mac's I'm trying to get back in shape... I have a personal blog at http://dillernet.com/apple where I've posted things over the years.

Jeff vs Steve

Here was my prototype - back in 2014 http://dillernet.com/apple/2014/09/04/jeff-vs-steve/ I just need to get the Canon Cat to print and I can make this happen- maybe in time for 2019 VCF East. -andy

New museum artifact: Symbolics 3620
by Herb Johnson 28 Nov '18

28 Nov '18

> We got a Symbolics 3620 today, no monitor or keyboard. I recall that Claude Kagan had a Symbolics machine in the Barn, which was damaged even before the fire claimed the barn. I believe the keyboard is unique; Web search shows it's certainly specialized for use. Apparently the keyboards have the Symbolics name on them, so they may be easy to spot. Evan, I suggest you determine the exact keyboard needed, so you and others can keep an eye out for it. Apropos our "keyboards" thread this month, people apparently will buy the keyboard as a collectable. Herb -- Herbert R.

Can somebody >(who is planning to arrive early-ish Saturday) please bring one? I have an AWS PS-25 that I use for weighing rocket for launch. It has a 55lbs max. I was not planning on attending too early because I'd planned to make ribs for all but the weather forecast does not look conducive for firing up the grill to make them -- heavy rain for the weekend, again. :( So, I may drop in circa mid-afternoon.

OT: Modern keyboard question
by Herb Johnson 28 Nov '18

28 Nov '18

> I'm also more of an Alps fan; my daily [desktop keybord] is an Apple Extended Keyboard II through an iMate ADB->USB adaptor. Since I sell ADB keyboards, this phrase caught my eye. Let's see what such adapters are about, these days. I presume 1) none are in current commercial production but 2) there's some hobby projects old and new about it. And I found I was likely right. "ADB to USB Connector Adapter" on that auction site, shows Griffin imate, AlphaSmart as apparently old brands, resale price $70-$100+; and maybe "Wombat" as some hobby class product at $59-$79. A Web search seems to zero in on a hobby project apparently called "tmk". Further searching and hopping about the Web, reveals some person calling themself "tmk", in Japan. There's some kind of code to run on microcontroller chips like Atmel AVR and Cortex-M; on some kind of hardware design (not physically complicated, interfaces and a MPU chip I imagine). The trail I was able to find amounts to: https://github.com/tmk/ https://geekhack.org/index.php?topic=14290.0 http://www.tmk-kbd.com/tmk_keyboard/editor/ Without a lecture from an old-guy; it's mostly a club around someone's microcontroller board for specific purposes. You have to join the conversation to figure out what you get, how to make it useful, see what's available now. All code is on github. The "sales" page seems to be an updated post in a keyboard discussion group (geekhack). More information is in various discussions. I don't think much of this kind of hobby-product-support, to be honest. I understand, this is how such things are done today. And of course - I may be wrong about "tmk" being a particularly popular old keyboard to USB solution. All I did was search the web cold, and see what Google came up with first. I'm not "in the club", so I know nothing. Maybe someone in that club, or another club, can reference other work. This is marginally within vintage-computing: this is about reuse of vintage tech. That's a fact: I sell ADB keyboards for current use, or disassembly, all the time. Otherwise I posted here what I found, to save my other know-nothing friends some of the time I spent on this subject this afternoon. Hope this is informative. Herb "click-clack" Johnson -- Herbert R.
