BYPASS does just that: bypasses all UIC-based checking - reads, writes, deletes, etc. It's handy when you need to delete a directory tree, but it's a dangerous one to leave on by default. My typical scheme is to leave BYPASS _disabled_ for the SYSTEM account asa default priv. CMKRNL allows your process to execute a "change mode to kernel" call, which allows you to read and write physical memory. With this priv, a malicious programmer can write code to peek at the process headers of other processes on the system (like a "who" command would) or even tweak their own header bits, possibly granting themselves permissions or changing their effective user name. I used to have programs in C and FORTRAN to do all these things, but they only work on pre-VMS-5 releases (and I didn't write them; I inherited them when I took over a VAX-11/750 w/Fuji Eagle, running VMS 4.2 about 13 years ago). -ethan ===== Infinet has been sold.

HP 9144 tapes

by rigdonj＠intellistar.net

I went and looked up the HP part number for the 9144 tapes. It's "HP 88140LC" for the 65 Mb ones and "HP 88140SC" for the 15 Mb ones. Joe

Finally got a "straight" DF32 yesterday

by dylanb＠sympatico.ca

Okay, I have the same drive(s-this weekend). The switch allows you to select one of three computers the drive will be used on: Straight 8 PDP-8/S PDP-8I the switch controls bus lines, (and selectors diode or resistor) logic for: pcl - straight 8 init - for 8i certain bus signals for 8/8s/8i, and other things I am finding in the schematic (mentioned changes between 8,8I,8/s). I haven't read the whole book yet as I have been inundated with documentation again... and my pick up this weekend will make my current document set look like a pamphlet. Do you have schematics? Contact me off the list. P.S. They did not put this switch on early model DF32s as only the 8,8/S was around. I am getting a newer drive that has the 8I switch (more changes). Does anyone know if digital fixed the head crashing problem with the DF32-D, or -F?

expanding PDP-8 memory (was Re: Finally got a "straight" DF32 yesterday)

Some people like to own the first. I have a population problem and have owned too many "firsts" including univac stuff. But, one the Straight 8 stuff - one sold on ebay this spring, complete untested for $1400 (but in great cosmetic condition) on eBay... they are getting more for Altairs :-(. I am picking up at least one over the next three weeks in MINT condition and I have a friend that wants one bad (I won't part with my 8/s) so I will sell it to him around $1000. The first PDP 8 was made for many years as DEC had problems with memory on the 8I. I have scrapped quite a few 8s (I am sure rack straight 8s as I have found front panel PCBs in my storage for them) over the years as I at the time I did not like 12 bit computers at all. (here is where I know large rocks will be thrown at me - I'm ready.. ;-)) A straight 8 in pieces is worth a lot more. You can sell the front panel on eBay for at least $250. Then, toss the core memory out of it for souvenirs and get an easy $500 - even maybe sell it to someone who needs it. You then could get a few hundred for the chassis (if its table top) from someone on eBay who wants to convert a rack mount unit. Sell the flip chips away or keep them as spares and you are way head of the standard $1400 for an 8. Original documents command good $$ too on eBay. A lot of folks have straight 8s which seems to be keeping the prices down.. it would not surprise me if there was a few hundred in the States alone as there are 8 "mint" running units in Australia! Abundance of a model dictates it's value.. ie: A LINC-8 and a PDP-8/S exists in very low numbers and fetch a lot more $$$. I've been talking to some folks on here about the $$ of old machines to get an idea of what "deep pockets" and collectors value the machines at.. and have found that I still can't get much for a Straight-8... But HEADS-UP - Some of these old ultra-rare minis are commanding some serious $$$. I was offered $12,000 and $15000 (this one wants to make another offer) for my 8/S (running) with docs and software in mint condition. I refused both offers (these were two eBay deep pockets that found me by looking at my "About Me" page.). I don't know what a LINC-8 in mint condition running is worth but probably more.... Another HEADS-UP - Honeywell 316s - Not whole but in parts. One of my 316s was carted to the dump this spring but spares for the machine are fetching big $$$ from those who want to hang up on their wall a piece of "ARPANET". The core memory gets at least $1000 CAD for the set and CPU boards/micropacs are fetching at least $60 US EACH!. Front Panel - no idea but probably a couple hundred. You can't get $4000US for a 316 whole but you can if you kill it. In my defense for such actions I do have/had "population" problems with some mini models.. The IBM 1130 took up the entire first floor of my parents home (it had every accessory), it was scrapped. I had 16 large racks of 316/ARPANET type stuf,Singers, Olivettes, etc... There is only so much one person can handle and "funding" is required for new loads of minis. >> You might want to think about doing that as it is nice to keep the same >> boards/technology in a transistor computer like that. > >I have every interest in keeping the technology "pure".

I have no interest in adding more memory to the Straight 8s. I was contemplating either replacing a core stack in an -8/L with battery- backed CMOS static RAM to free up a core stack for my -8/i, or adding 28K of CMOS static RAM to the -8/i. This is all to be able to run OS/8.

Shipping old heavy stuff

by allisonp＠world.std.com

<gets. Sounds like you did everything that you could to protect it. Do yo <have any other suggestions other than using someone other than UPS? Did <you file a claim with UPS? What were the results? Over the years I've shipped 3 VS3100s, two PC minitowers and an assortment of stuff via UPS. They all arrived as shipped, one peice no scars. Several errors are often made. BUBBLE DOES NOT WORK. Ok why? Most people put one or two layers of the large bubbles around an item and wedge it into a box. At arrives with the corners rounded. Look at any commercial product of similar weight and you find expanded foam or a VERY thick layer of stuff between the item and box. There's a reason for this. You drop a box 30" to concrete and there has to be enough padding to protect it. The other is use of extra cardboard at the corners to reinforce the padding and the external box or better yet wrap it, box it and pad it and box it. I've seen a lot of stuff shipped and if packaged correctly it will survice that 30" drop and then some. Oh, and Fedex will drop boxes too. Allison
