Most people posting in this thread have assumed that all Radio Shack stores were closing. That is not the case (at least for some time). Only about half of the company-owned stores are being closed. RS has published a list of the 1784 stores it wants to close: http://radioshackcorporation.com/pdfs/RS-Store-Closure-List_020415.pdf. Another 1750 stores will be taken over by Sprint for cell phone "store-within-stores" and about 1000 stores owned by franchisees are not part of the Chapter 11 bankruptcy proceedings. According to the Register (http://www.theregister.co.uk/2015/02/10/radioshack_store_axed/), the closings will take place by March 31. Two stores in downtown Chicago, near where I work, are on the list, so I will be watching them to see when they start selling off the merchandise. Bob

8" drive advice...

by supervinx＠libero.it

I need to connect an external 8" floppy drive to the FDADAP card. I've found two drives: NEC FD1165A and Shugart SA851. I have to buy ine of them. I'm about to choose the NEC one, since it doesn't need an AC power source. The Shugart SA851 is targeted 115 VAC, and I live in Europe. Beside power supply questions, are there other reasons why I should choose the Shugart? Hard sectored disk support? I only have to read/write IBM S/36 and 5120 floppy disks...

11/45 hack?

by jnc＠mercury.lcs.mit.edu

> From: Paul Anderson > it's not part of the 128 kw or 256 kb limit of the 45 Err, don't think so - that limit is in the addressing hardware in the CPU as well as in the UNIBUS. > From: Eric Smith > The 11/45 (or 11/50, 11/55) Fastbus memory, whether MOS or bipolar, is > not directly on either Unibus Actually, my understanding is that it is on UNIBUS B (or 2), via a second port to the memory; see this post: http://www.classiccmp.org/pipermail/cctalk/2015-February/003460.html which gave my understanding of how it works. And of course if you connect the two UNIBI together, it's therefore directly on UNIBUS A (or 1), as well. I.e. DMA devices can do transfers to/from it. Noel

OT : SAB3012 datasheet wanted

by ard＠p850ug1.demon.co.uk

This is sort-of off-topic : Does anyone have old-ish (1980s) Philips/Mullard/Signetics data books around. I am looking for a data sheet (or at least a pinout) for the SAB3012 remote control receiver IC (no, I do not mean SAB3021). I can find nothing on the web. (It's only sort-of off-topic as the IC is used in an old Viewdata / Prestel set which I guess is classic computing) -tony

Anyone need spare 11/05 - 11/10 keys?

by jnc＠mercury.lcs.mit.edu

I've discovered a local place that can create them, and just had one made, and it worked fine. I'm about to go back for two more: does anyone else need one/any? If so, please let me know (reply to me _only_, please - no need to gunk up the list with that). They'll be $2 each, to cover costs only. Noel

RA-81 issues

by g-wright＠att.net

Did not see this come through so here it s again. I have a rack full of RA81's, all Pass Rom base self test. If I try to spin up one of the drives, It will start to spin up and then just stop. There are no front panel lights that come on or codes on the terminal screen. all 3 drives do the same. These are not connected to a controller, and the manual does not say this is need. The forth one has no drive and the motor seems to turn hard, is there a brake on the motor ??? - what I'm I missing here Thanks Jerry
