LSSM - Large IBM haul

Hi all, In case others haven't seen this, the Large Scale Systems Museum has been given an opportunity to acquire a "near-mint" condition IBM System/370 and ES/9000 collection that has been maintained by a former field service tech since new:

Their latest comments on Facebook mention they're about halfway there. I just signed up for a service that reduces my lunch cost in NYC so I'll send them something. I'm hoping if I throw in $100 maybe enough others will follow. $8k to ship 8k pounds seems like a good deal, good on them! =] --

Martin's question is not nonsensical, and I imagine he understands the applicable networking concepts. His goal is to replicate the original dialup user experience and add a useful modern component - it's hard to justify keeping large machinery around if it's only there to look at. By adding the

Serial flash has an endurance between 10K-100K writes per cell so I think that would break down quickly. Wear-leveling on a serial device would be very slow... On Sat, Dec 15, 2018, 3:33 PM Gerhard Kreuzer via cctalk < cctalk@classiccmp.org wrote: > Hi Rod, > > take some microcontroller and some

If you want the real deal you can always make a driver out of a bunch of H-bridge ICs and an old core plane. I'll skip suggesting you weave your own core... On Sat, Dec 15, 2018, 2:01 PM systems_glitch via cctalk < cctalk@classiccmp.org wrote: > Chuck, > > FRAM is destructive read on the die,

Re: Core memory emulator using non volatile ram.

Texas Instruments' MSP430 MCUs use FRAM. This one for example: http://www.ti.com/product/msp430fr5969 costs ~$2.30. You could do some emulation in the same package, too. Not sure what your speed requirements are of course! =] -- Anders Nelson +1 (517) 775-6129 www.erogear.com On Sat, Dec 15,
