Looking for manuals, paperwork, SW for IBM 5322 Datamaster and IBM 5120 (5110 Type 3) and a case part

by afahimi＠fahimienterprises.com

Hello Everyone, I am new to the list although some members will know me from the Erik's VCFs. I recently acquired two 5322s and a 5120 and amazingly all three work to some extent. 1. My first 5322 blew the filter caps 30 seconds into powering it up. I am waiting for replacement parts. 2. The second one seems to be stable but the drives may have errors - they fail the ROM based diagnostics. 3. My 5120 is actually working well except the screen jumps sometimes so I am guessing the PSU is shaky (no pun intended) at best. I don't know enough about the system to do anything more complex then run the prerequisite "Hello World" program. I have been looking for documentations, HMS, programs etc. for either of these systems to help in troubleshooting and repair. While the 5110 (type 1 and 2) and to a smaller extent the 5100 documentation is available as PFDs the other two systems have been ignored for the most part. Any help is appreciated in the form of actual physical product, digital info, or even personal experiences. I am also looking for the bottom half of the back portion of a 5322 if anyone is parting one out. Thank you.

MorphOS for PowerPC- Fun OS worth checking out

by slandon110＠gmail.com

I recently downloaded and installed MorphOS the Amiga Compatible operating system for PowerPC G4 systems. So far its really cool, Especially if you are into Amiga, You can run most classic amiga software on it natively :), If you got a spare iBook G4 or old G4/G5 based system laying around, Give it a look. Its a ton of fun to work with :) http://www.morphos-team.net/

MicroPDP-11/73 On/Off Switch

by pontus＠update.uu.se

Hi I'm restoring a MicroPDP-11/73. I've made some initial notes here: http://www.pdp8.se/pdp1173_restore.shtml The ON/OFF rocker switch is broken. Three small plastic teeth that hold the springs in place have broken of and a forth is cracked and will soon break. I've tried three different kinds of glue without a getting a strong enough bond. I will make another attempt with a fourth kind. But, I wonder if these are available somewhere? The only marking I've found is "UND.LAB.INC.LIST" which seems to be a brand with several different kinds of rockers, some available but not the one used on this MicroPDP-11. By the looks of it, the same switch is used on MicroVAX. In the meantime I will probably take one from a spare machine. I'm borrowing a picture from the net here, but it is like the switch labled "1 0" here: https://www.codehosting.net/blog/images/pdp/frontpanel.jpg /P

Needed - Static RAM board & more for Altair / S-100 project

by drlegendre＠gmail.com

Howdy folks, I'm just about in the final stretch of my Altair 8800 restoration (more like a total re-construction..) and there are a couple of parts that I obviously need to pick-up. FYI, this is a 'to factory' restoration, so the 8800 is going back to where it was when it was built from a kit. This isn't totally true, as this particular unit was later fitted with the "B" power supply and that will remain. It's obviously far superior to the "A" version and I don't have any of the A PSU parts. First off, I need a static RAM board for it. Ideally, I'd like a 1K or 4K MITS part.. but any +small capacity+ static board will probably fit the bill, particularly if it's has hand-drawn traces and is built on the clear-whitish board material as is the Processor board. I'm not sure what to call this color or type of board.. so please chime-in. Secondly, I'm thinking really hard about replacing the motherboard (or as MITS called it the 'expansion board'). As it sits, it has a Processor Tech. MB-1 16 (!!) slot board that's going to look a little silly with only two or maybe three cards plugged in it. Does anyone have an original 2 or 4-slot mainboard, or even a 3rd party board that's not so dang huge? So to this end, I have a few items to trade if that would work. There's a 64K (max 256K) dynamic RAM board, a Z-80 board, a floppy disk controller board, what looks like an RS-232 board, and a couple other minor items. All parts are in great shape, look ready to run. TIA for any and all help. Feel free to contact me off-list to work out deals. -Bill

putting drivers on a floppy disk

by rmx44＠aim.com

i happen to have gotten windows 95 installed on my old panasonic toughbook cf-27 but i have one issue where the drivers i need are a bit to large for a floppy disk and even trying to compress the files in a 7zip or a zip file does no good. i still need an audio driver and the pcmcia card slot driver to install. also i wish i could find a usb driver for my iomega zip 100 usb zip drive for windows 95 but thats not possible and since lenovo took over iomega they dropped lots of old drivers. i have tried to track down iomega drivers but i end up at sites that claim they have the driver only to be given an installer to a driver program thats a scam. maybe someone out there could help i still need the audio driver which is a yamaha sound card and windows 95 claims its a creative when its not also i need the pcmcia driver.

Phil Katz and PKZip (was: putting drivers on a floppy disk)

by billdeg＠buzz1.com

>...Phil Katz and PKZip... I still have my original copy of PKZip with manual. Here is an example of a "post-vintage" yet historic software killer ap whatever you want to call it. I agree that this is/was a very important piece of software and should be recognized. Here's to Phil! Even though they're off-topic here, I still make a point to archive the 1990-1996 software that I found useful. Many of us back then used to carry around our super support disk that almost always included pzkip, pkunzip and pkfix, laplink (ll.exe), and many others. From a preservation standpoint, I have saved these disks "as they were" because they help put things in perspective. I also had early Win 3.1 TCPIP windsock, BTRIEVE, editors, etc. PCTools disks, etc. Bill

source for some MM5204 EPROMs?

by spacewar＠gmail.com

I'd like to get at least 2, and preferably 4 or more, MM5204 EPROMs. This is a 512x8 that isn't pin-compatible with anything else (except the MM5214 masked ROM). Does anyone care to sell some, or know a seller? If all else fails I could make adapters to use a more modern part, but I'd rather avoid that if possible. Thanks! Eric
