26 Jan '16

LOCATION: InfoAge Building 9032A - (2201 Marconi Road, Wall Township, NJ) DATE: Saturday January 30 & Sunday 31 TIME: Start about 10 A.M. on Saturday end whenever. End about 5 P.M. on Sunday. (Starts around 10 A.M. Sunday morning) COST: $10 for all members attending the workshop, which MARCH donates to InfoAge as thanks for providing the space for us. EQUIPMENT: MARCH will provide a table and you can use any available electrical outlet. Bring your own tools, power strips, power cords and supplies etc. DRINKS: You should bring your own. However, I will bring a case of water bottles free for everyone to take. FOOD: You provide your own. We may order pizza or go out to a dinner. Usually we make a decision when everyone gets hungry. PARKING: Park behind the back ramp of 9032A (which is around the building), or in the main parking lot, NOT in the courtyard. Please close the front gate behind you after entering. Not sure of the situation with snow right now near the back ramp. I'm hoping that a lot of it will be melted by Saturday. LOOSE THEME: Commodore 64 and Commodore 1541. Feel free to bring whatever you want, or just watch. There are plenty of people to help and one can learn a lot by watching. HAM RADIO: Martin Flynn said that if anyone is interested he can open N2MO. Let me know if anyone has a desire for it. If you need to contact me, my smart phone is: 732-759-1783. Hope to see lots of you there! :-D Jeff Brace

FS: MITS 88-VI (RTC) Vector Interrupt and Real Time Clock
by Systems Glitch 26 Jan '16

26 Jan '16

link: http://www.ebay.com/itm/272116893925 This one appears to be pretty early. The silkscreen is black instead of yellow, but it does have a copyright date of 1975, and no solder mask. It includes an early Intel 8214 Priority Interrupt Controller in white ceramic with gold lid and gold leads. I would guess it was assembled in mid-1976 by the IC date codes. You'll need one of these for MITS timesharing BASIC, or if you want to use interrupt-driven I/O devices. I've tested everything on this board except the 60 Hz timebase. That requires modifying your S-100 box to put unfiltered, unregulated 16 VAC on pin 55 of your motherboard, which I didn't want to do. I tested the interrupt controller by writing an initialization routine based off the example in the MITS 88-VI manual, and writing interrupt service routines to display the interrupt level on my IMSAI's programmed output register. Thanks, Jonathan

About restoring capacitance-keyswitch keyboards, including source materials, and work by several former-MARCH members: http://www.retrotechnology.com/restore/sol_keys.html Metalized Mylar in rolls may be available at "dollar stores" as gift-wrapping. It's just aluminum on Mylar. Snack chip bags, cookie bags as noted, helium balloons, gift wrap - on and on. the challenge is the right "foam" material. Bill Degnan came up with a good material - see my Web site, and his. Herb -- Herbert R. Johnson, New Jersey USA http://www.retrotechnology.com OR .net

Joe, if you're reading this, I put your account into temporary moderation to see if that stops the zombie message. :) Have to log off now so we'll see tomorrow if that fixed it.

My VCF East class: historical research methods
by Evan Koblentz 26 Jan '16

26 Jan '16

Being a vintage computer hobbyist means doing more than just fixing stuff. I'm planning to give a Friday talk on historical research methods, because I learned a few things in 18 years as a tech journalist and 12 as a computer historian that may help some people.
