You might want to share a bit about yourself and your current 8-bit Heath interests and activities. I have a growing collection of H8, H89 and Z100 machines in various degrees of (dis)repair, but the H8 is my favorite. My personal quest is to build a functional Trionyx box with Trionyx motherboard, 64K (or more) of Trionyx RAM, 4-MHz Trionyx Z80 cpu and hex front panel and running HDOS 3. Sitting next to it will be my early H8 with cassette and paper tape. I think I'll pass on the H9. More globally, I have several hopes for the list, but the major one is to preserve and exchange information that is quickly evaporating. We will have an ftp site online shortly which will be a repository for documentation and software. Experiences restoring, rennovating and updating systems is welcome. Several members are working on imaging and emulations; I hope we can come up with common formats and shared procedures. But mostly, we're here to support each other and continue the fellowship of "hobby computing".

I saw the notice about the new list on Heathkit ham radio list and thought '...why not!'. So here goes. My present Heath/Zenith computers include one Z-100 (with a 10MB harddisk - wow!) - the low profile model; one Z-100 All-In-One with a pair of floppy drives, a pair of 8" drives (not the Heathkit variety although I did have some for awhile) for either one; and one remaining H-89 with a H-77 dual disk drive (converted to soft-sector DS DD, if I remember correctly). I also have an H-25 printer holding down one corner of the attic. And tons of software and documentation. I worked at Heathkit from 1977 to 1981 in the Ham Radio group and got my first computer (not including an upgraded education/lab unit - the one with 6800 - with the optional BASIC and memory expansion box) - an H-89 - my first year there (August if I remember correctly). The H-89 I have now is not, I think, my first one. I had two more H-89s but they got traded off/sold a good many years ago. None of these has been fired up for a good many years and one of these days I will do a major house cleaning and get rid of at least one of the Z-100s. Would also love to give the H-25 away to a good home (hint). For a couple of years, I was member of the Heath Users Group (HUG) in St. Joesph - in fact, I was the newsletter editor for a couple of years using my trusty old H-14 printer. The name 'Staunch89er' rings a loud bell! How about a little history to fill in the gaps in that area? I may even have a few of the back issues my self (along with a couple years worth of REMark and one or two other .... Sextant? does that ring a bell?). Got to sign off now and get to work on another newsletter - if I want to go to bed at a decent time ... or at all, the way things are going.

I've always run the site on the premise that if a copyright holder doesn't want their material to be hosted on the site, they'll let me know. This occured when Leor Zolman asked me to pull the BDS C archives and replace them with a link to his site now that he's released it to the public. It hasn't happened since. I also will not host material that is still being sold, nor will I host material less than 10 years old. The aim of the site is to preserve software & data for computers that are becoming more and more rare & precious every day. If a copyright holder doesn't want their contribution to the golden age of computing preserved, so be it.

Recently acquired an H8 - complete with all manuals and in good condition. It's the basic unit, with two add-in cards: 4k ram and serial/cassette. I do not have a disk drive system, but would love to find one. I would also very much like to obtain other Heath/Zenith machines. Still trying to locate the cassette software. My interest is mainly in preserving history - As time permits, I have been preparing "packages" for my machines, which include detailed "inside and out" photographs of the machine and all subassemblies & peripherals, scans of all available documentation and reference material, and a PC based simulation. If I can find a decent free simulator, I taylor it as much as possible to reflect the actual machine in my collection. I've written my own simulator for a few of the machines. - So far the only H8 simulator I've found is not usable to me, so it looks like I will be writing my own - since I already have the 8080 engine, this shouldn't be too difficult. So far I have completed about a dozen of the 70+ machines I currently have on hand (This takes a *LOT* of time!) I also run a mail order software company specailizing in development tools for 8-bit families including the 8080 (CPU used in my H8). The H8 is of special interest to me because it's an early machine based on the 8080 processor. Although my very first home computer was a RCA 1802 based machine in the mid 70's, I quickly "graduated" to a homebuilt 8080 machine, and then got an Altair 8800, also 8080 based (which I still have :-) I've written a TON of 8080 software in the early years, including: My own O.S., BASIC, Assembler, C compiler, lots of system utilities and other things.

This was on the heels of my first computer experience, with the TRS-80 Model I in the late 70's. This started my career of computer-related "stuff"... everything from software, to hardware, to semi-conductors. I spend my early years as a hardware/software engineer, but have since moved on into the "wonderful world" of finance. And now I'm collecting the old machines. Why? Nostagia partially, but also it gives me the opportunity to be an engineer again. My collection consists of the various models of the "second generation" machines: the TRS-80, Apple ][, Commodore (including one of my favorites, the chiclet keyboarded PET 2001), Atari, TI, and the Heathkit H89 (actually a Z89). My "first generation" collection is far smaller, currently, and consists of the DG Nova 3, Kim-1, and H8. I have an IMSAI coming soon. My collection has the dubious distinction that everything works. Granted, not every PART of everything, :-) but all of the machines boot, and can run software. My recent project, which some great guys on this list are helping me with, is a floppy emulator called the "SVD" (which stands for the Semi-Virtual Disk). As I was working on my old machines, I continually ran into the problem of finding software to run on them. Note that although I love software emulators, I love seeing the old software run on the old machines even more. Fortunately, most of the software exists SOMEWHERE. But the tough part is getting the software to run ON the machine. So I built the SVD to allow me to run downloaded software on the old machines through the existing floppy interface. In other words, you can hook up the SVD to the floppy cable of the old machine, download a diskette image from your PC to the SVD, and boot the old machine. Simple. So the SVD now supports the TRS-80 Models I/III/IV and the H8/H89 hard-sector. I'm working on support for my other old machines and won't stop until they ALL work! :-) The Northstar is next on the list, and then the Apple ][. Other "easier" machines will be sprinkled in, such as the CoCo. Head on over to www.theSVD.com for more info. I'm a big proponent of archiving all of the old software and documentation. Fortunately, there are a few very good sites, and people who are rapidly getting the software and doc up and available. I have just a few floppy images on my site, but am anxious to help expand it and/or another site. Anyway, that's a long-winded intro to what I'm up to. Big thanks to Jack and the guys for getting this list up! Note to those guys who responded to my request a couple months ago for HDOS information - I have the HDOS file system up and running on the SVD now...thanks for your help!

As I was working on my old machines, I continually ran into the problem of finding software to run on them. Note that although I love software emulators, I love seeing the old software run on the old machines even more. Fortunately, most of the software exists SOMEWHERE. But the tough part is getting the software to run ON the machine. So I built the SVD to allow me to run downloaded software on the old machines through the existing floppy interface. In other words, you can hook up the SVD to the floppy cable of the old machine, download a diskette image from your PC to the SVD, and boot the old machine. Simple. So the SVD now supports the TRS-80 Models I/III/IV and the H8/H89 hard-sector. I'm working on support for my other old machines and won't stop until they ALL work! :-) The Northstar is next on the list, and then the Apple ][. Other "easier" machines will be sprinkled in, such as the CoCo. Head on over to www.theSVD.com for more info. I'm a big proponent of archiving all of the old software and documentation. Fortunately, there are a few very good sites, and people who are rapidly getting the software and doc up and available. I have just a few floppy images on my site, but am anxious to help expand it and/or another site. Anyway, that's a long-winded intro to what I'm up to. Big thanks to Jack and the guys for getting this list up! Note to those guys who responded to my request a couple months ago for HDOS information - I have the HDOS file system up and running on the SVD now...thanks for your help!

Recently acquired an H8 - complete with all manuals and in good condition. It's the basic unit, with two add-in cards: 4k ram and serial/cassette. I do not have a disk drive system, but would love to find one. I would also very much like to obtain other Heath/Zenith machines. Still trying to locate the cassette software. My interest is mainly in preserving history - As time permits, I have been preparing "packages" for my machines, which include detailed "inside and out" photographs of the machine and all subassemblies & peripherals, scans of all available documentation and reference material, and a PC based simulation. If I can find a decent free simulator, I taylor it as much as possible to reflect the actual machine in my collection. I've written my own simulator for a few of the machines. - So far the only H8 simulator I've found is not usable to me, so it looks like I will be writing my own - since I already have the 8080 engine, this shouldn't be too difficult. So far I have completed about a dozen of the 70+ machines I currently have on hand (This takes a *LOT* of time!) I also run a mail order software company specailizing in development tools for 8-bit families including the 8080 (CPU used in my H8). The H8 is of special interest to me because it's an early machine based on the 8080 processor. Although my very first home computer was a RCA 1802 based machine in the mid 70's, I quickly "graduated" to a homebuilt 8080 machine, and then got an Altair 8800, also 8080 based (which I still have :-) I've written a TON of 8080 software in the early years, including: My own O.S., BASIC, Assembler, C compiler, lots of system utilities and other things.

I bought the controller about a year and a half ago from a guy in Belgium who was selling a large collection of spare parts. It was among them, in a baggie with an EPROM and PROM, and two other gates. And there was a manual. I followed the instructions in the manual, and on power up got/get the Magnolia prompt, but the keyboard is unresponsive. Sometimes there is garbage before or after the Magnolia monitor prompt, and sometimes I don't get the prompt at all, just streams of garbage. I never get far enough to start a boot and get a drive selected. I have completely backed out the configuration to hard-sector only, verified the machine, and rolled forward through the setup instructions two or three times. The results are the same each time. I understand that the Magnolia version of MTR autobauds with the terminal logic board (which is set for the standard 9600 baud by the way). My suspicion was that the version of the MTR EPROM may be down-rev (the good EPROM sitting in a machine I didn't buy of course), so that was my next thing to try. I only have the one EPROM, but Jack Rubin has a Magnolia as well and I was hoping his was a newer version. Unfortunately, I don't have the kit in front of me, so I can't tell you what version is stamped on the EPROM. I realize that's not much to go on, but any clues you could offer me would be a great help, I'm sure! Thanks!

Lee, thank you, but I have originals, so I'm good shape, I think. Are you also sending Jack the Magnolia CP/M docs? I have that on my desk to scan for him, so you might save me an hour with my scanner. :-) > You also need the Magnolia boot ROM and I/O decoder. I think I have both > of these as well. Finally, you need Magnolia CP/M. I do not think I have > any bootable Magnolia CP/M disks, but maybe someone out there does. Boot ROM and decoder I have, although there is a question in my mind if the boot ROM is the right version. Oh, and by "boot ROM", I assume you mean the EPROM normally occupied by MTR-88/89/90. The other question is what revisions or rework may be necessary to the '89 CPU board itself beyond the EPROM/PROM replacements. I remember pulling a gate and the decode PROM and installing a daughter card that also had a connector to the 128K memory card, but It's been a couple of months since I tried to get this working, so rather than me handing out more sketchy details from my poor memory, I need to go through the install process again so I can document/share exactly what I've done and what the results are. I have images of Magnolia boot disks from Don Maslin, but I have not been able to test them as yet, and have no idea if they are somebody's working disks or real distribution masters. As always, thanks for your help, Lee!

Do you have these half-size booklets: 1. Magnolia Microsystems Monitor EPROM 444-84B for the Heath/Zenith Z89 and Z90 Computer Systems, Revised 11/8/82. 2. Installing Magnolia Microsystems' 77316 Double Density Disk Controller in a Heath/Zenith Z89 or Z90 Computer System, Revised 11/8/82. Let me know if you have those and we'll go from there. There was also a 1983 Heathkit Christmas Catalog in there -- quite a nostalgia trip. Paul Pennington Augusta, Georgia -- This list is for Beta testers of the SEBHC Mailing List
