Re: Help identifying IC

The mid-70s saw a plethora of dedicated-logic LSI TOD clock chips in 24-28 and sometimes 40 pin packages. Most prevalent IME were those made by National, Mostek and Fairchild. Going by the labelling for the other two chips, fair chance the ID of the big chip is staring right at us: MPS 7123.

A walk through of my legendary warehouse sale in the 1990s.

This is a digitized HI8 tape of a walk through of an early Warehouse Sale I ran from 1995 to 1998. There is a small sections of collectable computers in the middle of the tape with a few others scattered through the sale. Fond memories and hard to believe it was 22 years ago.

Help identifying IC

Hi all -- I picked up this little toy at VCF West last summer: https://1drv.ms/i/s!Aqb36sqnCIfMouYd0HV0ZThE3FnE_Q As far as I can tell, it's supposed to be a clock and I assume it was a kit -- this one was definitely hand-assembled.  It's powered by two AA's (apparently, there are no

Re: GT-40 etc.

As I understand it, the power for the DACs actually comes from the monitor (VR12/4/7) and thus you can’t use any monitor without some additional circuitry to provide the power to the DACs. TTFN - Guy > On Jan 20, 2018, at 5:32 PM, Paul Anderson via cctalk > wrote: > >

Sorry for the off topic post. I'm hoping that someone here might have seen a (what I consider to be) a computer lore type story about a contractor that was brought in part way through a project to consolidate three DCs into one. - In the end he managed to do it early and under budget. The

There was a guy in the Netherlands (I believe) who was trying to sell a GT40 for $14K with no delivery option. If I were on the east coast (or just not very busy) I would have higher on the ebay system just to get the GT40 + monitor. Marc On Sat, Jan 20, 2018 at 1:12 PM, Noel Chiappa via cctalk

Re: Power plugs and cables for the IBM 3420

Those cables came with my 4331 system. I’ll go and dig them out and maybe there will be some sort of part number. At worst I’ll post some pictures. You might also want to look up the various IBM docs on the 3420 and 3803. They should specify those cables. I also have all the docs in an IBM

Can any of you identify which power plugs models these are. They are on my IBM 3420 tapes and connect to the IBM 3803 controller, 3 phase: https://www.dropbox.com/s/ftfpg0owdvb173u/IMG_5066.JPG?dl=0 https://www.dropbox.com/s/uyzpwcp6sjkvrpf/IMG_5067.JPG?dl=0 These are for the large vacuum
