M688 Flip Chip Unibus Power Fail Driver Modules

by jnc＠mercury.lcs.mit.edu

> From: Ethan Dicks > what are these found in? The "Spare Module Handbook" lists: RH11-AB TM11, TMA11 MX11-B Does _anyone_ actually have an MX11? Any documentation would also be welcome; all I've been able to find out about it is a listing for the addresses of control registers. Noel

M688 Flip Chip Unibus Power Fail Driver Modules

by jnc＠mercury.lcs.mit.edu

Anyone need/want a couple of these? Someone has a group of 5 for sale on eBait (#184317666245), and I want a couple, but not _5_. The seller didn't respond to a request to split up the lot, so I'd like to go in with a couple of other people on the. Any takers? Noel

KL11 asynchronous serial line interface on eBay

by jnc＠mercury.lcs.mit.edu

Here: https://www.ebay.com/itm/284137678274 and: https://gunkies.org/wiki/KL11_asynchronous_serial_line_interface if you want to know what it is. The lot includes an M105 Address Selector and an M782 Interrupt Control (which you'd need to actually use it); the price for the group is quite reasonable. Noel

Dec RQDX: What kind of chips on it?

by cz＠alembic.crystel.com

Can someone check to see if a RQDX2 used the Western Digital chips to interface to MFM drives? Reason I'm asking is the MFM emulator can identify an RQDX3, and also a Pro/350 controller but this particular RD52 I have (which was verified by me to run Digital Mumps) is reading as: root at beaglebone:~/mfm# ./mfm_read -a Board revision C detected Found drive at select 3 Returning to track 0 Drive RPM 3525.4 Matches count 36 for controller WD_1006 Header CRC: Polynomial 0x1021 length 16 initial value 0xffff Sector length 512 Data CRC: Polynomial 0x1021 length 16 initial value 0xffff Interleave mismatch previous entry 0, 9 was 1 now 0 Selected head 8 found 0, last good head found 7 Read errors trying to determine sector numbering, results may be in error Number of heads 8 number of sectors 18 first sector 0 Unable to determine interleave.

Keyboard storage, part 2

by aperry＠snowmoose.com

An update on keyboard storage, which I asked about here last month. I ordered some USPS Large Flat Rate Priority Mail "board game" boxes. This is a size not usually available at the post office and come 25 in a pack. They are a good size for mailing (and I am glad that I ordered them so I can use them for that), but I don't think they work for keyboard storage. They are so much larger than the keyboards that I am storing that lots of packing material is needed so they don't move around. Also, they are designed to be sealed and shipped, so there isn't a convenient way to open them once they have been closed. Next, I ordered the Uline keyboard boxes. I had to get 25 of them and they are not free ($2.70 per box plus tax and shipping). They can be open and closed. They are a much closer to the size of a keyboard (surprise, surprise!) so not much packing material needed, but they are slightly smaller than a Sun Type 5c (as well as Axil) keyboard and needed to modified for those two. No modification needed to store a Sun Type 4 or CompuAdd Sun-compatible keyboard in one. I haven't tried a Sun Type 6 yet. To anyone in the Seattle area that need keyboard boxes, I will probably have 10-15 of them once I get all of my keyboards packed. If you would like any, let me know. alan

Setting switches for a Vertex 150 possibly for a perq

by cz＠alembic.crystel.com

Hi! I'm trying to read possible Perq2 data off a 40mb Vertex V150 drive. Unfortunately the switches were scrambled and I can't seem to figure out which settings work. Does anyone have one that can check their switch settings? This doesn't seem to work: https://stason.org/TULARC/pc/hard-drives-hdd/vertex/V150-43MB-5-25-FH-MFM-S…

I know multiple people that have signed victims up to mailing lists -- many of which were questionable content -- as an attack on said victims. Pretending to send email from said victims to cause bounces and ire to be (mis)directed at them seems quite the same to me. Five years? Sure. Many people will create filters and simply ignore the messages. As such, it's effectively internet background radiation / wasted bits. > Whack-a-Mole works when everyone whacks their moles.

As far as I know, > no other email provider allows this. I've not seen anything in any provider's terms of service that say anything about what type of email they receive, save for exceedingly few categories; child porn and illegal activity among the short list. I have yet to see anybody state that sending an email to an invalid email address and (potentially) receiving a bounce is illegal. So, again, no grounds for Google to do anything. Feel free to try to get Google to change their terms of service. > I don't see how this relates to Google allowing their services to > be used to test my mail server (and likely thousands of others too) > numerous times over multiple years for being an open relay that could > be exploited to distribute spam. Are the messages /originating/ from Google / Gmail? Or are the messages /originating/ from somewhere else and causing the bounces to go to Google / Gmail? The former is something Google cares about. The latter quite likely is not. > If you burn a junk (snail) mail, could there be a security lapse in > your furnace that would cause it to be replicated into a thousand > copies of itself, run up your chimney and distribute itself into > thousands of your neighbours letterboxes?

According to WhoIs, that address space belongs to Serverion BV.

Sadly, many companies leave a LOT to be desired when it comes to abuse handling, especially when the abuse originates from their organization.
