Hi all, I think I'm not getting it. I have a BA23 with a 11/83 and a RQDX3. I have set the IDs on the RD54s (XT2190s) to ID 0 (pin 1 and C) and ID 1 (pin 2 and C) but yet ZRQCH0 or RT-11 does not seem to find the second disk, which should be DU1, right? Am I missing something here? regards, reiche

DEC InfoServer 100 Firmware archived anywhere?

by glen.slick＠gmail.com

Has anyone archived the DEC InfoServer 100 firmware anywhere? I see that CHM has one, http://www.computerhistory.org/collections/catalog/102682746 Is the InfoServer 100 motherboard identical to that of the MicroVAX 3100 Model 20, except for the firmware? From information I've found on the net that appears that it might be the case but I haven't found a definitive answer on that. I have a MicroVAX 3100 Model 20 that isn't too interesting and it might be more interesting if it could be converted to an InfoServer 100 with a firmware swap. -Glen

I have never seen a "real" one but I believe it has some kind of transition to the round cable (which then has the quick-disconnect on the other end)? BTW, Continental Computers answered my quote request with they can "let it go for $145"... that's about four times what I expected to pay for one! -Charles

Wanting a SWTPC 6800 but need more information

by brad＠bettercomputing.net

Hey guys, I am keeping an eye out for an SWTPC 6800 system. I was hoping for one with the SWTPC black case. I thought that'd be nice to go with the CT-1024 terminal I have (if I get it working). Have developed a bit of a fascination with SWTPC lately. I'm just wondering if anyone knows what a typical value for a single unit with nothing fancy is? I note a recent auction had two of them together for $1400 - Am I correct to imply from that that the value of an individual unit is probably less than $700 (that set was unique due to the systems being linked and that control box they had, I think). I keep seeing this one popping up on ebay: http://www.ebay.com/itm/SWTPC-6800-in-custom-case-with-PLEXIGLASS-Cover-Rare -/151200879158?pt=US_Vintage_Computers_Mainframes <http://www.ebay.com/itm/SWTPC-6800-in-custom-case-with-PLEXIGLASS-Cover-Rar e-/151200879158?pt=US_Vintage_Computers_Mainframes&hash=item2334465236> &hash=item2334465236 But it's got a custom case, and looking at the written dates on the ROMs appears to be later than what I believe was the 6800's heyday (mid to late 70s?). Did SWTPC sell 6800s as parts like that, or is this something someone cobbled together? Brad

HP 97500-85620 Drives.

by me＠GarrettMeiers.com

Does anyone have any information about these HP hard drives? https://www.dropbox.com/sc/xovh6yyel6zhzil/B4UelO3lhK Model 97500-85620. They have a 40 pin connector on them, but no power input. Doing a search shoes a mix of companies describing these as either HPIB or IDE. I believe HPIB is probably the case, but I can't find any documentation for the drives to be 100% sure. I would love to find a manual/spec sheet for the drives. Thanks! Garrett Meiers Founder, BitHistory.org & President, ConsulNIX, LLC www.BitHistory.org www.linkedin.com/in/theunixguy

BNC Video out and LCD monitor with VGA D-Sub video in

by aswood＠t-online.de

Hello all, how to connect a HP 9000/300 with RGB BNC video out to a modern LCD monitor, which has only a D-Sub VGA video connector. Can I simply use a classic BNC to VGA cable just reverse connected? Since from 2015 on there will be no new monitor supporting VGA singnals anymore what we have to do to connect our old workstations? Andreas

IBM 5120

by webmaster＠supervinx.com

Hi! It's mandatory to connect the printer? Trying to access the internal drives leads in 013 error (Device not attached), both for D80 and D40. I've not opened it yet. The drives spin, I can hear the noise inserting a disk. Thanks!

Intel MDS 225 system being auctioned by Chicago Transit Authority

by brad＠bettercomputing.net

I've been looking at the various means if creating a disk from image.. but given the hardware required and rigging it all up.. I'd rather just obtain a copy somewhere i think.

Yeah, I remember both the DD and SD versions of the board set--and I remember how hot the channel board ran.? One of the first questions I asked on the VCF posting was whether or not the OP had the DD board set--kind of hard to miss.? He reported that he did not, so he's running off the 8271 built-in controller. If he was using the DD board set, that would create an interesting issue, as it uses MMFM, not MFM for encoding.? Not something easily done on a PC. Fortunately, it's clear that plain old SSSD disks will work just fine--and he can probably use a PC to write the images to disk. --Chuck

S-100 buffered prototyping board PCBs are here

by LYNCHAJ＠YAHOO.COM

Hi! Good news! The S-100 buffered prototyping board PCBs have arrived! Here is your chance to build your own S-100 board project! Here is more information on the S-100 buffered prototyping board. These boards have been respun and contain some minor improvements from previous versions. http://www.s100computers.com/My%20System%20Pages/Prototype%20Board/Prototype %20Board.htm The PCBs will be $20 each as per the usual arrangement. Shipping in the US is $3 for a single PCB and $2 for each additional PCB. Shipping internationally is $12.75 for a single PCB and $3 for each additional PCB. This is for the bare basics USPS first class postage with no tracking or insurance. The builder assumes all risk of delivery as per usual arrangement. My preference is to sell these PCBs to vintage computer/home brew computer/classic computer hobbyists first but if there are any remaining boards I will put them on eBay. Please send a PayPal to LYNCHAJ at YAHOO.COM with the subject "S-100 buffered prototyping board" and I will send your board(s). There are several PCBs left. Thanks and have a nice day! Andrew Lynch
