I ran across some data in the pile of what I've been collecting, and there's some stuff there apparently by Signetics (?) referring to what they're calling "Utilogic II" -- is this stuff RTL or what? It doesn't say. Dates are in the late 1960s, and it looks like it, but I figured I'd ask in here... -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, ?a critter that can be killed but can't be tamed. ?--Robert A.

DEC CP/M speaking machines: =========================== 1 Vt180 complete (dual RX180s) 2 Vt180 CP/M board built up as standalone one modded for 6mhz 1 Vt185 Thats a Vt125 + Vt180. In the non operational list: 11/23B uPDP-11 in a BA23 pedestal that while complete with 11/23B, M8057 memory, DHV11, RQDX2 and RD52, RX50 it requries cleaning and testing. H11 Backplane complete with LSI-11 CPU, 16k of ram, two serial cards and a parallel card of heath origin. Some day I'll find the case/power supply for it. All parts are tested as working. Small 11/23 system using a H9281-BC (12x2 slots) filled with: M8186 1/23 (Overclocked CPU mod) 4 M8059 MSV11 ram DLV11j, RQDX3 with M9058 distribution board. (for RX33 and RD31) MRV-11 Eprom card with MSCP boot. VK170 with matching LK02 keyboard and a monitor. The VK170 is a minimal VT52 on a dual width card for packaged systems that communicates via RS232 to system and the bus use is power only. This is waiting on being packed in a reasonable nonDEC box with a DEC PS and fans. The boards are known working and the backplane is already jumpered as Q22. Generally in my house operational means I can actually turn it on and play and it has a permanent spot that is easily accessable. One project that is in process is a H9800 desk/rack that will replace the existing standard steel office desk. the system to be installed there will be 11/23B in BA11s with a hand made Disk box for RX33 and RD52s. I have two boxes (Xerox Paper sized) of tested boards enough to build another few 11/23s and a few uVAXII as my spares. Failed boards get repaird when I feel like it so I have good boards around. Who was it that has the SIG of "DEC had then what you wish you could buy now." ? Allison

Who was putting together the TSX+ archive?

by aek＠bitsavers.org

> Is this already in the archive, or would it be useful? Lyle Bickley was putting together the software archive unfortunately, he's no longer subscribed here. The TSX docs are under pdf/dec/pdp11/tsxPlus and I have some manuals scanned from Feb 84.

I remember being somewhat dumbfounded yet amused when Apple made the big deal about having the first "World First 64-bit desktop with native 32-bit application compatibility" as I looked over at my DEC 3000, Indigo2 R10k, HP 9000 C180, and Sun Ultra 1. Ah - here's the marketing drivel: "On other platforms, switching to a 64-bit computer requires migrating to a 64-bit operating system (and purchasing 64-bit applications) or running a 32-bit operating system in a slow emulation mode.With the PowerPC G5, the transition to a 64-bit system is seamless:Current 32-bit code?such as existing Mac OS X and Classic applications?runs natively at processor speed, with no interruptions to your workflow and no additional investment in software." Gee that's funny- IRIX did that in '96, Solaris in '99, and HP-UX in '99 or '00 - and DEC's VEST wasn't too shabby in '92 even if it wasn't transparent.

Core duo SC/MP?

by dogas＠bellsouth.net

Hi there folks. I just got a sweet NS LCDS (low cost dev system) with a SC/MP II processor card and nice set of docs on the chip itself, the lcds,appnotes,and assembly programming It looks pretty easy to add more than one scamp to the same bus and I was wondering if there are known multiproc scamp systems or archetectures out there. So, in looking for a few additional sc/mp II chips (national semi ISP8060 or ISP 8-A/600N) , the only place I could find was the CPU Shack.com He said he could get them, but 8 would have to be purchased at $14/chip. I only want two more for my rig, any interest in filling out the rest of an order for the other 6? Or does anyone have them cheaper? Thanks - Mike

[SPAM(date)] Re: Burroughs B80 rescued

by stevew＠ka6s.com

Some possible suggestions: Serial line- likely this is a Burroughs Multidrop line - RS485 using a polled protocol. Should be compatible with TD830/TD850/MT983 Burroughs terminals etc. Disk drive control was done by the CPUs - most of the drives were not terribly smart. Best bet is bitsavers as you've already suggested. I've never used a B80 myself, - but am an expert on B1900 stuff. Steve Wilson

VSII/GPX joy (and minor annoyance)

One half of the base board does however have circuitry connected to those pads that are just linked by grant continuity traces on the second half (and the 4-plane memory boards), so I figured it might actually be doing something useful with it.

I found the pinouts of the BC18Z somewhere (and I'm aware that there is a buggy version), so I should be able to construct a replacement. Your offer for the other stuff is gratefully taken, let me know what I should be on the lookout for you in private mail. The MVII at University has a TK70 installed, but as it will probably never see much use even if we manage to fix the supply, I might be able to get it traded for a TK50 (which was what the machine originally had). -- Arno Kletzander Stud.

"destructive read of a ROM"?

by legalize＠xmission.com

Over on comp.terminals someone wrote this about the VT100: "The power-on operation does a "destructive" read of the ROM-based firmware. After so many power-ups, the ROM becomes unreadable. This was a design issue at the time - the technology to fix it did not evolve until the VT200 series." Is this true? I've never heard of a ROM being damaged by reading it a lot. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Still have that. Since then I've aquired two more. However the screen size 40x anything is painfully short for me. At the other end the software was decent and the time (1981-2ish) it wasn't a bad machine to use off the serial port with a real terminal (you could do that with some software). I still enjoy bugertime and some fo the games on it. Allison

"Chuck" question

by cclist＠sydex.com

A friend forwarded this message to me and I agreed to post it. Please note that she's an archivist and not a collector: "I tried posting this elsewhere but other than one reply that some schools have old computers around, nobody's come up with a good explanation. So I thought I'd try Archives List in the hopes that somebody who either attended Stanford University or works there might be able to say if the reference is some sort of in-joke. The show is Chuck on which premiered on NBC this week and the question is: Why would a character who's 27 years old say he'd developed a video game on a TRS80 when he attended Stanford? Assuming a normal progress through school, Chuck attended college between 1997 and 2002 or perhaps a few years earlier if he was a child prodigy (of which there is no evidence in the pilot.) Would he have been able to to find a Trash-80 there and use it to design a video game? TRS-80's were first manufactured before he was born and production ended by the time he entered kindergarten. Although the Model 100 laptop enjoyed some popularity - especially with reporters - until the 1990's, surviving TRS-80's were antiques by the time the character was in high school. I've checked various message boards, etc. but haven't found a mention of this - just lots of comparisons to Jake 2.0 and a fairly even mix of pans and praise for the show.
