Anyone have one of these development systems? I've had the manual for a while, and I think I just found a bunch of software for it. Looks to be Multibus-based from the pics in the manual on bitsavers.

PDP-11/35 available.

by quapla＠xs4all.nl

After long deliberation, I have decided to let go of one of my nicest best machines. It is a 2 rack config and comes complete with spares etc. For all details & history of this machine, see http://www.groenenberg.net/download/1135 Please contact me off list for more details if wanted, as well as offers for this machine. Please note, no cherry picking, this is an all or nothing deal. Regards, Ed -- Dit is een HTML vrije email / This is an HTML free email. Zeg NEE tegen de 'slimme' meter.

Apollo DN3xxx 3Com Ethernet Card Find / QIC Tape Misery

by cube1＠charter.net

As an FYI, I recently purchased an Ethernet card, 3Com Assembly number 2012-01 (I believe this is a 3c505). It works perfectly. I am now in the process of attempting to read in as many of the (over 100, maybe 50 or so without duplicates) tape cartridges as I can, and will forward them off to Al Kossow that CHM when I get them read (presumably on a DVD). The biggest issue with the tapes is that Apollo used some pretty cheap cartridges at time to deliver software (after all, why should they need to last?? 8^)), and the little rubber belts inside the QIC-24 cartridges have gone bad in many of them. Fortunately, I have some relatively newer 3M DC600 cartridges that I can use to supply a substitute belt, and when done carefully (e.g., first manually rewind the cartridge PAST the load point (but not past the end!) before switching the belt to avoid problems) seems to be working. Unfortunately, I blarched a set of SR10.2 install media learning all of this. 8^P) But, I just read in a tape of 12MB successfully after doing a belt replacement (a tape with DPCI software, I think - it is still in the drive). In addition, many of the tapes I have were left in the middle, which seems to present data readability issues. We'll see. You can find these Ethernet cards on: EBay right now has two of them: http://www.ebay.com/itm/3COM-ISA-Ethernet-Card-2012-00-RevB-/350290188652?p… http://www.ebay.com/itm/3Com-2012-16-Bit-ISA-Ethernet-Coax-Network-Card-/19… And also at Pinnacle Micro / EZ-Systems may also still have some. Part number ASSY-2012-01 "ASSY-2012-01 3Com Refurbished Assembly 201201 ETHERLINK 16 BIT 30 Day Warranty" They are $28.75 from Pinnacle, but the minimum with shipping is $50, so you end up paying $50. Suggest adding a comment that you do indeed want the "LONG version of the card" (they called me to confirm that). I got mine there because they offer a 30 day warranty (at least on the one I bought), which is what motivated me to drag out my DN3000 and try and read some tapes and FTP the files and test them with the DN3xxx emulator inside of the "mess" simulator. Even one of the bad SR10.2 boot tapes I could at least boot from after the transfer, and enough of the tape was there that some of the programs would run (e.g., calendar, invol, config all ran). I saw at least one card somewhere else on the net for a reasonable price, but I forget where. JRJ

rarest computers. was: RE: Xerox Alto Restoration + Emulation

by andrewjlynch＠me.com

Re 480z Hi Jules As far as I know the metal case was an inner London education authority variant (ilea). At that time every piece of electronic equipment used in the authorities schools was retro fitted with huge "child proof" casing. This meant that every electronic item had ugly GLC boxes fitted before we could use them. The 480zs were issued to all ILEA schools in this form in the early 80s. I remember using them at that time and wishing we had the BBCs. The rumour was that they'd done a deal with RM. Hope you don't mind me contacting you like this. You email came up on a search I'd put in for the 480z Andrew Sent from my iPad

Digi-Comp I (was: Re: VintageAppleNMore Etsy Store)

Maximum clock rate seems to be about 1 Hz for reliable operation; I have not tried ice-tea cooling for over-clocking. I have implemented a 1-bit + 2-bit adder, output register obviously the same as the input registers (concatenated), and a 3-bit counter with rollover. Pretty sure I'll need a memory expansion to implement tic-tac-toe. I highly recommend playing with it!

Once more common sense went down the drain and I find myself the "proud" owner of a Univac 9400 console. The 1$ price seemed to good to let go. Now what the heck am I going to do with it..... Jos

SCSI <-> USB

by emu＠e-bbes.com

Hi all, know it sounds weird (but I travel a lot, laptop user on the road). Anyway, does USB-SCSI adapter exist, if yes, are they really worth the money? My laptop doesn't even have PCMCIA slots anymore ... Cheers & thanks

I was just looking at the picture and googling for any info. I don't have any experience with this product but the fact that it's called an "rtVAX 300" suggests to me that it may run VAXELN, a Pascal-centric real-time application environment. This may be an application engine for running a VAXELN app. I saw some presentations at a DECUS or two but never worked with it. -ethan
