Sage & Stride Users

Missing, besides these Basic & Fortran compilers, are : -
- A full install set for Unistride : the tape I had has an unrecoverable error on the /usr section ( 2nd tapefile)
- a full set of IV22 would be welcome.
- also a good picture of the Video PCB would be welcome.

...as is anything else Stride related.

Blown powersupplies can be repaired, and disk images can be made using David Gesswein's MFM-reader. He kindly added Stride support, which i used to partially recover Unistride. Alas, on my 3-disk Stride 440 the broken harddisk was the one containing the /usr section, thus again out of luck.

If you have a installtape I'd be very interested. Under no circumstance try to read these on an old unrestored tapedrive, as this will destroy the tape 100%....

My SAGE IV has a dead Hard Drive. I also have one of David's MFM emulators in my HP-9133 taking the place of a Seagate ST-225 that was working when I removed it.
Is there a suitable image of a SAGE IV (18 MB) drive available for David's emulator? Or, maybe I can get the SAGE to recognize the ST-225.

I wish I had more to contribute here than just questions. I truly regret getting rid of my SAGE II many years ago.
Who knew that retro computing would become so popular...

Back when I had my original SAGE II it came with BASIC and FORTRAN compilers. None of the disk images that I have found on line include these.
Do you have them in your collection?

I also have 2 stride 460 hard drives with stuff on them i haven't archived that I need to archive.

I will have to look through what I have.
 
The MFM-emulator only supports reading Stride / Sage disks, emulation is not (yet?) possible.
Formatting a real, working ST225, should not be an issue. I recently formatted a few harddisks on my Stride.

where do i read up on this MFM-emulator?

Hi,

I just bought a replacement power supply that is 200W instead of the 140W that came with my 460, I made sure it had the same voltages and that the AMPs exceeded what the old power supply was. I need to look into getting the old power supply repaired also.

I have NOTHING Unistride NOR the 68010 CPU and MMU daughterboard for the 400 series, Both of my 460s have 68000's one is a 10Mhz and the other is a 12Mhz. one of the CPUs sits on a daughterboard (older revision board) and the other CPU is directly plugged into the motherboard that is on the newer revision motherboard.

everything I have is on Floppy and I LONG archived it into IMD format. I have 2 hard drives I need to get archived onto a floppy disk and then archived into IMD format. I'm trying to figure out if there is an IMD format reader for Unix, either FreeBSD or MacOS so i can read descriptions and look at the directories of these IMD images,

I'm waiting on a replacement hard drive for my NAS where ALL my stuff resides as I use ZFS and once that arrives I can merge in the contents from the FTP server into my directories of stuff.

I have a excel document with everything I have both hardware and software wise,

I collaborated with sageand stride(i fact most of the manual scans came from my hard copies), and have 3 sage Ivs. Manuals and software floppies for Hyperforth+UCSD Iv, Mirage (APL), Tripos, Idris(2 versions), LispKit Lisp and afew otjer things--I am still trying to find a BOS floppy(I have the manuals). Alos the UCSD :ibrary(I held the Australian copies for soem time)(plus oter ntuque machinesas well)

cheers

I do have MOST of the UCSD library that was public back then, I couldn't recover some of the floppies though.

I take it the disks you read wouldn't work for emulation? I didn't find a report on emulation problems in my emails.

Here : https://www.pdp8online.com/mfm/mfm.shtml

And the developer for this system is "djg", who has just joined this discussion to mention that the MFM-emulator should support Stride-disk emulation !
Sorry for the misinformation !

Thanks for the link.

I read through the thread on google groups, looks like he hasn't added emulation for the Stride 400 series but will read the hard drive? be nice to use the emulator to emulate the hard drive. I have a few micropolis hard drives with the stiction problem myself. I need to figure out how to get that resolved.
 
I need to track down some floppies so I can archive off the hard drives I have in my Stride 400 series. anybody got any thoughts on tracking down some that arent gonna cost me a fortune?

right now I don't have the cash to buy an emulator as I'm still paying my cancer surgery bills from last December so I'm kinda forced down the floppy path at this point.

I have bought 3.5" floppies from floppydisks.com with good success but I have never tried their 5.25".
I just watch eBay periodically for good deals with factory sealed packages.
 
I am attempting to format an ST-225 to replace the failed drive in my SAGE IV. I created a document (attached PDF) That shows the Winchester Configuration Screen. The top section shows the "default?" configuration for Winchester #1 from the floppy images that are circulating on line. In the bottom section, I have modified the parameters to reflect the information that I can find about the ST-225 (Bold Face Text).

Can someone take a look at this and let me know if any of the non-bolded items need to be changed, and/or where I might find the related information?

Thanks in advance for any assistance.

I had an offline exchange with jdreesen. His statement was from ambiguous wording in a previous email where I was intending to say I hadn't added support for converting a disk image back into an emulator file. He interpreted it as emulation wasn't supported. Emulation support is unknown. Like real hard drive normally will work with any computer the emulator should also. In practice since its implemented in software there are some timing differences that cause issues with a few machines.

It can read the hard drive and create a sector image of the disk. Extracting files is outside the scope of my software. Don't know what tools exist for that.

thank you for clarifying, once I can afford one I will buy one.
