Hello!

by scaron＠umich.edu

Hi everyone, I just wanted to send a brief little message out to (re?)introduce myself to the group... I was one of the earlier contributors to the original classiccmp list maybe 15 years ago but I drifted away from the list and computer collecting in general ca. 2001-2002 as I got busier with my university studies and I had accomplished most of my collecting goals. One engineering degree, a successful IT career and a starter home later... I've put down some roots, got a house of my own... perfect time to gather up all my big heavy things and bring them home :) I figured it would be fun to chat with some other folks who are still in the hobby. I left my collection in the hands of some folks that I shouldn't have and it suffered some losses over the years... maybe I can do some wheeling and dealing here to recover some of what I'm missing? My main focus in collecting is mostly old minis and "workstation" class hardware. I like to play with SGI, NeXT, DEC Alpha, DEC VAX, DEC PDP, Motorola MVME boards of all types, 68k Macs and to a lesser extent, Sun SPARC equipment. I'm mostly looking to pick up a few Q-bus and Unibus boards... I'm trying to finish up a complete board set for a KA650-based Qbus VAX (anyone got a few 16 MB MS650s or a Q-bus SCSI card at a reasonable price?), and I need a RX01/02 controller for my PDP-11/34a. I'd love another DEC BA23 at some point to mound said complete KA650-based boardset... I used to have three very nice BA23s in my inventory... one perfectly filled out uVAX III... all were lost :( I'm mostly looking to trade or sell some miscellaneous parts for SGI, NeXT, Apple and maybe to a lesser extent, DEC. Excited to be back! Best, Sean

Pile of Mac G4s

by nospam212-cctalk＠yahoo.com

I have about 12 various models of Mac G4 towers. These were used for audio recording and art production and were being tossed. Before I spend the time to see what all is in each machine and their conditions I wanted to see if there was any interest in the systems. If not I won't bother with them as I have samples in my own collection already. Be aware they are rather heavy for shipping. Systems are located in Houston, TX. David www.trailingedge.com

MFM reader emulator

by djg＠pdp8online.com

I have now completed layouts for a PCB for the MFM disk reader and emulator that I mentioned back in February. I will add to my order boards for others who are interested. I am not planning to kit or assemble. You will have to do that yourself. For information on the board see http://www.pdp8online.com/mfm/ Email me if you have any comments or questions. I did two different layouts, one all through hole and one with 3 surface mount chips that has some minor advantages. See link above for discussion. I plan to only order one version. If you are interested in a PCB's email me with 1) How many you wish 2) If you prefer or are only interested in the through hole or surface mount version. Unless you state I don't need to I will email you back when I get ready to order with the final price for confirmation that you still wish them. I plan to collect money when I am ready to ship them. The cost to make one is: Beaglebone $55 (they increased the flash by 2G and the price by $10) PCB $30 (depends significantly on quantity) Parts $54. Can reduce by $24 if you don't need the holdup capacitors. See the BOM for parts and prices. See description of board for what the holdup capacitors do. TBD Shipping Unless only a few are desired I will likely buy a couple cheap PCB's without the hard gold on the edge fingers to verify I haven't made a serious error. This will delay final order. I tried to get my cat to peer review but it only shredded the paper.

Catch and Halt Fire - Drama set in early days of personal computing

by sellam＠vintagetech.com

I watched about 3 minutes. Pure garbage. Halt and Catch Fire is not a real computer instruction that caused a race condition that made the computer stop working. I imagine a bunch of teenagers are scouring Intel technical manuals looking for the Code 2 Duo equivalent of HCF. No one looked, acted, or talked like that back in the early 1980s (I remember, I was there). Especially not IBM sales people. If you could find a chick anywhere that looked 1/4 as cute as the chick in the opening scene and who knew as much about computers, you were either in the future, watching a bad 2014 television drama, or you were someplace private by yourself with your pants down lost in your imagination. I'm sure I could come up with more criticisms if I could deaden my senses enough without taking out critical life functions to watch the rest. Unfortunately, this program was designed for the braindead, technically illiterate cultural group that comprises television watchers generally. Whoever wrote this knows a computer collector. However, based on the level of comprehension of the subject matter that gets incorporated into the script, the writer probably only likes the computer collector in as much as they can get fodder for their crappy TV scripts. If any Hollywood people are reading this and want to make a good historical computer based drama or movie (it's been all downhill since War Games), you know how to contact me. -- Sellam ibn Abraham VintageTech ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintagetech.com Whatsoever a man soweth, that shall he also reap.

Catch and Halt Fire - Drama set in early days of personal

by kurt＠hamm.me

I was there in the late 70s and early 80s. I absolutely enjoyed the first episode and looked at it like the beginnings of Compaq. The legal restrictions on reverse engineering were close enough. The sets and wardrobe were obviously well thought out and seemed familiar to me. I enjoyed them immensely. I loved seeing those old computers. This is a great opportunity to engage an audience outside of our close knit community. So many people lived through the time if not as profoundly as we did. How can this show be a bad thing for us? Sellam continues to be a prick about anything related to what he feels is his claim to computer history. I see his post as fishing for some piece of the action. It included a plea for the producers to call him and smacked of sour grapes for not being consulted. For my part, I am disgusted by anyone who would make a value judgement about physical appearance especially related to technical competency. It is a completely subjective evaluation and has no place in this discussion. We should relax and enjoy the first major impetus for remembering and collecting this past. IMHO. Kurt

Ersatz-11 V7.1

by wilson＠dbit.com

V7.1 of Ersatz-11 is done. New features include: - DMP11/DMV11 network ports. - DDCMP over TCP and UDP (as well as serial lines). - Kermit client for transferring files in and out of the PDP-11 over any emulated serial line (KERMIT command and KERMIT: pseudo-driver). - "MOUNT ddcu: BAD: /LIST:badblks.txt ..." adds fake bad blocks (from a list in a file) to any disk (for testing PDP-11 utilities). - "MOUNT ddcu: ... {/NOPAD | /PAD:NULL | /PAD:RAM}" selects how to handle emulating disks with an image file (or physical drive) that's smaller than the drive being emulated. (/PAD:RAM is currently an experimental feature and may have bugs -- it's intended for systems that use the tail end of the drive as swap space.) - DPDISK: and DPTAPE: (BOTH UNSUPPORTED) set up dual-ported disks and tapes. Any disk or tape type can be mounted on one of these pseudo-devices, after which units 0 and 1 of the pseudo-device represent the two ports which may in turn each be mounted on different PDP-11 controllers, presumably on different processors of a multi-processor system. Unsupported, as I said, just like all mP features. - "SET TTu: DL11A" (needed by DOS/BATCH for TT0:). - "SET PCLOG n" enlarges the number of logged PC values that can be shown with SHOW PCLOG. - New native "SYS" utilities for Linux, OS/2, and Windows, for making disks (or flash drives) boot the stand-alone version of E11. The Linux and Windows versions try to notice if a drive (e.g. USB flash card that came pre-partitioned) hasn't been made "active" and/or is missing the MBR bootstrap, and fixes it (may require privs). If anyone can please tell me what sys calls in OS/2 will find out which physical drive owns a FAT volume given the drive letter, I'd appreciate it! - The stand-alone version's bootstrap supports USB drives (including flash). Also there's a bootable CD, but since there's currently no ATAPI dev driver or ISO9660 FS driver, it can't install E11 onto a hard drive, and it requires a FAT volume to hold .DSK files etc. So it's more of a proof of concept than something useful (but it's an easy way to try out the stand-alone version of E11). Bug fixes and tweaks as usual (sorry about that .TAP seeking thing in V7.0!). As usual, the Demo version can be downloaded from: http://www.dbit.com/demo.html Updates have been mailed to commercial users with current subscriptions. John Wilson D Bit
