The following items are free to anyone who can pick up near Vancouver,
B.C.
Xerox 820 c/w Software & Manuals
Morrow Designs (Startronics??) MP100 Serial Daisy Wheel Printer
Two Wyse 50 Terminals
The Xerox will boot but won't load the O/S. Bad disk or drive?
The Wyse terminals were both working last time I used them.

You mentioned two items on my list: Xerox 820 and Wyse 50s. I'm in Dallas so its not likely I can pick them up. Around 1983, I bought three Xerox 820 motherboards at $50 each and built systems around them. Xerox had a computer factory/warehouse in a nearby Addison and sold some parts/discontinued/refurbished stuff. I'm not sure if I saved one of those 820 systems. I used a Wyse-50 terminal to hook-up my HD64180 SBCs: (1) a SB-180 (Ciracia's Micromint design) and (2) an obscure Southern Pacific LTD, Mountainside Computer "MSC-LAT" which was a great 64180 SBC running CP/M Plus with 8" drives. The Wyse-50 flyback transformer burned out and I boxed it all up for a later day. Thirty years later... I found the Wyse-50, my MSC-LAT and a Paper Tiger serial printer when looking for my SB-180 last week. This time I'll get the Wyse-50 fixed. -Jay in Dallas http://compgroups.net/comp.os.cpm/

I remember buying just the bare "bigboard" from a surplus mail order catalogue, with schematics, ROMS and instructions on how to build it up from there. I was not comfortable with assembling such a large system since a lot of time, effort & money (in parts) was at risk. My patience was rewarded, for Xerox surplus later sold entire 802-II systems (main unit with monitor, keyboard) for $100. I later acquired several more for cheap or free at the good-old NJ Trenton Computer Fest. Sadly, I never had enough bench space for them and gave them all away to a fellow who lamented giving up his. As to the Wyse-50, I too held onto mine because I find it more comfortable to use than VT220 or 320. It tilts and the kybd is not too wide or heavy. > I used a Wyse-50 terminal to hook-up my HD64180 SBCs: > (1) a SB-180 (Ciracia's Micromint design) I still have Muppet lunchboxes to someday re-create that BYTE cover of the SB180 in the lunchbox with floppy drives. I have 2 SB180s. One I bought already assembled in a PC-clone case. Sorry, I forgot the kind person who sold it to me cheap. And a wire-wrapped SB180 from Alan Strassberg. I still have not found a project worthy of it :-/ > an obscure ... which was a great 64180 SBC > running CP/M Plus with 8" drives. That sounds really retro for the 8" floppy drives yet turbo-charged with the 64180 (256k DRAM?) I found Z80 CPUs hiding in many devices: smart modems, terminal servers, SCSI controllers, intelligent serial ports, AppleTalk interface cards. It's so hard being a Zilog advocate after the IXSYS merger/takeover. At least Captain Zilog's back! -- jeffj

Most of the connectors are not. I hadn't looked at it in quite some time but you made me curious.

The complete machine was to expensive and heavy to buy it from Italy. so just bought the motherboard to turn it back on as photos https://www.flickr.com/photos/117100272@N02/12443160633/ cabling all in a old midtower PC case and built a ps2/parallel converter and a special cabling to use a couple of 3.5" drivers using a standard flat cable.

Mine halts upon power up with a DRAM error with no clue what chip, address or bit is in error. The CPU is soldered onto the motherboard so I cannot use my in circuit emulator :-(

jeffj: Re: SB-180 (Ciarcia / Micromint) -------------------------------- As you have a couple of SB-180s and as I've not dug mine out of storage yet... maybe you can answer a question about them? One of the 64180 systems I bought back in the mid 80s had a great floppy utility for reading all sorts of floppy disks formats... I can't remember the name of the software but it came in a black and green package. I sure it was a 5 1/4 inch floppy system so I expect it was part of the Micromint bundled SB-180 deal. Does that ring a bell? Re: Hitachi HD64180s -------------------- As much of a fan as I was of the 64180 back in the 80s, I'm now looking very seriously at doing a design with the eZ80... it seems like the perfect system for any modern Z80 CP/M system. I've already read about several systems done since around 2007 when it was a hotter topic on comp.os.cpm - I was glad to see there is current mention of it as I was beginning to think it wasn't going to be available for long (Mouser and Digi-Key didn't carry any stock of the latest Dev.Sys and had a minimum order of 3 required... that's a bad sign that availability of a processor is suspect). Luckily that seems not to be the case... just another distributor stocking annoyance. Re: Wyse 50 Terminals --------------------- Yeah that terminal was a nice package. I used a Wyse-50 as the man-machine interface on a document sorter for the govt and liked the terminal so much I bought one for myself. I wrote the code for that machine on a Ampro Little Board with the Wyse but somehow I failed to buy myself an Ampro Little Board too. I'll buy one someday - I have all the documentation from that project. :) Since I found my Wyse-50 last week, I've found website on how to repair them I saw one article suggesting a replacement part. When the Wyse failed in the 80s I tried to find information like that on the BBS networks (Fidonet) but no luck. Guess information access has improved with the internet. Re: Are dumb terminals still available? --------------------------------------- That brings up something I've been pondering as I reacquaint myself with the CP/M world after being missing in action since the 80s... Are dumb terminals still available? The ubiquitous PC often substitutes for dumb terminals (I've done that in the lab too). I wouldn't mind buying some new terminals for by HD64180 systems but I'd prefer they last longer than my Wyse did. I just don't want to hook my CP/M systems to a PC... seems wrong to be compounding the idiocy of overkill in having a fancy PC do simple jobs a CP/M system would better. :) -Jay_in_Dallas

To roger: Thanks for the URL. Nice to know dumb terminals are still available. You quoted a message I tried to send last night from another computer of mine. I conclude it sent my message repeatedly as I tried to diagnose why the PC never acknowledged sending anything. In the future I stick with this system for posting. Thanks to whomever cleaned that up for me. Jeffj wrote: > As to the Wyse-50, I too held onto mine because I > find it more comfortable… It tilts and the > keyboard is not too wide or heavy. Agreed. It didn’t take up too much desk space and was perfect for its function. "Perfect for its function" is not an attribute I'd assign to many PCs today.

However, in my opinion the floppy drive dependency of CP/M systems needs to be left to the restoration projects and the museum pieces. Its really not an appropriate media for today and it will just hinder CP/M system acceptance as a valid, simple solution to home and office computing without all the accumulating burdens of an overly complex PC system. “Lose the floppy drives!” -says the VersaFloppy-III designer of antiquity. :) Time to embrace SD cards, microSD cards, USB memory sticks and reduce the bulk out of the CP/M system. No more moving parts prone to maintenance issues and delays. CP/M systems (any variant) could easily become market contenders for efficient, low cost computing and simplicity if its “re-imagined” for today’s peripherals. I guess that tips my hand that I’m researching an eZ80 retro-fusion design. Jay wrote: > MSC-LAT…an obscure ... 64180 SBC running > CP/M Plus with 8" drives. Jeffj wrote: > That sounds really retro for the 8" floppy > drives yet turbo-charged with the 64180... True, but I bought the latest and best 8” drives of the day. Still have them stored. As I recall they are half-high, 96tpi, DC motor (28Vdc?) DSDD Mitsubishis(?) so I think got my money’s worth out of the diskettes. The obscure “Southern Pacific Mountainside MSC-LAT” is an internet-ghost today. I bought the 512K version. I was doing an assembly language program that utilized the Yale star data base of ~9,000 objects to write a 3-D computation traversal image based on a BYTE magazine article about how to do 3-D computation in matrices for applications like the crude flight simulators of that day. As the Wyse 50 didn’t have graphics, I used my Paper Tiger printer to print the progression of scenes… I’ve seen that printout in my old fanfold paper archives; crude but still cool. :) Not exactly an practical application program but it was interesting… as I recall the biggest part was getting the Yale star chart reformed from a text dump ino 5 or so compressed files on BBS systems, into a form that the program could crunch. I think I used Dbase and Wordstar to manipulate the data. Jeffj wrote: > It's so hard being a Zilog advocate > after the IXSYS merger/takeover Well the way I look at it is that they saved the existence of Zilog. I had more trouble believing the management of Zilog following the heyday of the Z80, than I do with IXYS today. I’m glad that someone kept Zilog available… it was the best processor to work with. And I’m itching to get an eZ80 development system to work on for a project. Jay_in_Dallas --

The Z-system was a nice step forward from CP/M, 'till Linux
(with Xinu, Minix, Uzi and such along the way).
I'm unsure how far the Z-system went
and what was the preferred platform.
I suspect the SB180 was the most popular
since it had the clout of Byte, BIX, Steve Ciarcia and all.
Too much to research ...

Funny you should mention museums.
I'm active with MARCH: the NJ vintage computer museum
http://www.midatlanticretro.com
a member of the InfoAge science center
http://www.infoage.org
located on what was Marconi's Belmar wireless station,
then an army base:

> Its really not an appropriate media for today
BUT it's essential for reading all the archives
still on floppy (not yet copied to new media/formats).
Particularly when it natively handles wonky formats.

And to our chagrin, the paper's still useful
whereas most machine formats are hard to read back.
It probably makes for a nice flip-book animation.
I remember the ads for the Paper Tiger.
And the Banana/Gorilla ("buy a banana, save a bunch").
I still have my Olivetti spark-jet printer from the DAK catalogue.
And a few copies of the Damark closeout/liquidation catalogue
to prove the silly prices we used to pay for printers and disks!

Bill may be on to something... All other CP/M restoration projects, EXCEPT Bill's, are going to fight the dreaded Exploding Tantalum Capacitors. Bill is far more of a visionary than the rest of us. Like the preparation of the Pharaohs of Egypt, Bill has prepared his Big Board to pass through near-eternity unscathed by the effects of evil Tantalums. When Bill restores his Big Board, he's likely to have the least frustrating project among us all; a big project nonetheless... but more importantly, a *happy project*. The lessons for us all might be to buy a KIT instead to set adrift on the river Styx, (excuse the mixed religious references) complete with all components sans Tantalums, it a sealed sarcophagus to keep out moisture and versions of Windows 24. -Jay_in_Dallas http://compgroups.net/comp.os.cpm/

I'm likely to get more active in that data recovery effort once I get a couple of my CP/M era systems running again. Back in the early 80s I designed and programmed MultiBus and S-100 IEEE-696 controllers for hard drives and floppy drives. If I dust off some of those synapses and can get a clean drive running, I'll research all the floppy and drive restoration webpages, collect all the ancient chip PDFs and spare time permitting, I should be able write code for grabbing old data. I'll start with my own collection dating all the way back to Intel ISIS systems with 8" drives. I did buy a copy of UNIFORM (supports reading various formats) for my SB-180 so at least I won't have to re-invent every wheel in my collection. Reading my North Star diskettes will probably be the greatest challenge when considering all the restoration required to run the host. Maybe I'll cheat and just wire an interface from the new eZ80 dev.sys to the north star drive ribbon cable and rip it real-time. (That actually sounds like a more feasible solution). -Jay_in_Dallas

If you could get disk images of the ISIS disks that would be great. We now have Intel MDS emulation with ISIS:
Press Spacebar to activate

Single Density Controller at 0x88 :F2:F3: or :F4:F5:
ISIS Boot Ver 2.0
"I" to boot ISIS
"C" to boot CP/M
"M" for Monitor - i
