Sage & Stride Users

I have recently acquired a new set of disks for the SAGE which is different from the disk sets available from the website. If wanted, I could contribute the disk images.

I have designed several 680x0 computers recently and ported cpm68k to them. All they have are 680x0, DRAM, and serial ports. I wonder what additional hardware are required to run SAGE/Stride software?

a upd765 based floppy interface and 2 intel 8253 times would be a minimum. Schematics for the Sage II / IV machines are available.
Sage IV has an in-house developed MFM-harddisk interface.

My newly designed 680x0 hardware also have compact flash interface. The serial port device is 68681 which does have timers on chip, so If SAGE/Stride interface to hardware through CPM BIOS, then perhaps I can work around the specific floppy controller and timers. The big question is how video and keyboard were implemented. This is the area I may need specific hardware to be compatible.

Not implemented at all : these systems were intended to be used with (multiple !) ASCII terminals. And you will be rewriting a lot of stuff if you have different implementation for the serial channels, the FDC, the timers and so on...
 
There was a graphics board available "Pluto Board", but I have not found any schematics nor software for it until now.
 
Currently looking for some IMD images ( UCSD or CP/M ) that fit a Stride 420 system. The images that are out there are all for Sage II or IV, even the ones marked "Stride"....
There is a Stride 420 board on my desk that wants to boot into an OS !
 
Thanks for the links, however these are for the Sage II/IV, even those marked Stride...

Sage II/IV use the intel 8251 UART, the Stride 4x0 machines use the MC68681 dual UART. The OS disk are therefore not portable between the machines....

Stride software seems very hard to come by...

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

Hi Marcus,

Would you be able to Imagedisk those floppies ? There is a distinct lack of software, even more so for the Stride 4x0 machines...

I was able to score a bunch of original Stride4xx system floppies and have put images on my FTP-server :

ftp://ftp.dreesen.ch/Sage&Stride

The pSystem IV21 set is complete, I believe the PDOS set is also complete.
Partial sets of CPM/68K, Psystem IV22 and the accessory floppy sets of the Unistride system are there. The Unistride tape itself is not yet recovered.

Al, if you'd like to add these to Bitsavers I can upload them...

Hello. I had a SAGE II back in the 80's. It was the first computer that I ever owned. I am not sure what happened to it.
However, I recently acquired a SAGE IV for just the cost of shipping. It is mostly working except for the Hard Drive and an intermittent RAM fault on the upper board.
I have disconnected the upper board for now and have basically a single drive SAGE II.

1) I would love to collaborate with other SAGE IV users.
2) I have downloaded the archive of the old sageandstride site, but the SAGE IV Getting Started manual is incomplete. Do any of you have a scanned copy of this entire document?
3) I am very happy to know that I am not the only one who is still interested in these machines!

Cheers! and happy sageing!

SAGE IV Update.
I cobbled together a RAM Chip tester using an Arduino and replaced all of the defective RAM.
I now have all 1024k.

Next task is to create a good SYSTEM.MISCINFO and GOTXY that plays nice with the terminal mode of my HP-150.
It is working nicely in terminal emulation, though.

The next hurdle is to get a working Hard Drive...

Hi Jos,

for the Sage II/IV, I have the original master sets of IV.13, BIOS Source Code, Word7, Timberline, CPM, and boot disk from earlier IV releases, etc
for the Stride 400 series, I have original master complete sets of IV.21 and IV.22, Word7, Spell7, Timberline, and a few other things.

and I have a lot of internal stuff from Sage and Stride machines, everything from budgets to press releases to catalog pages and lots of info on power supplies, etc. 90% of that stuff ill never share.

with all that said I mirrored the directory listed above and am currently going through everything, I have a spreadsheet of all my disks that I've archived

documentation wise, I have the 4Mb mod for the Sage II/IV that was done by Chuck at ASCII Electronics in the Reno area along with schematic mods and some other TSB-related docs.

hardware wise I got 2 x Stride 460's (one has a blown power supply I'm currently looking for a replacement for), some pal chips for the I/O boards, a Video board for the Stride 400 series, and a few hard drives I need to go through before they lose their bits also have a pair of Sage II/IV's and a bunch of different fronts and rear panels (different than the world has seen) and have a boxful of 80 track floppy drives.

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?
