It's been a long time, and I've forgotten the details. But I ran across it when I was designing the H-1000 (a replacement CPU board for the H89). The old 8250 had a bus fight problem with the Z80 at 4 MHz, and both new and old 8250 had problems at both 2 MHz and 4 MHz. National had an application note that outlined the problem. When you compare the H89 and H89-A schematics, you'll see Heath added a 74LS74 between the buffered read and write lines (/BRD and /BWR) and the 8250's Data In Strobe (DISTR) and Data Out Strobe (/DOSTR) pins. My guess is that the 8250 was slow at taking its data off the bus during reads, and slow at latching its data in on writes.

When I got the H8-4 I still had an 8080 in my H8. After Heath was unwilling to replace more than one of the 8250s I found a couple elsewhere that worked. They could have been older or newer. Later I upgraded to a DG Z80 and the 8250s on the H8-4 continued to work, though I rarely ran at 4.096MHz. The Z80 did break my clever core interface, though. (It started a memory cycle before it knew whether there was going to be a read or a write since the first half of the core cycle was a destructive read in either case. This was necessary to run with 0 wait states on the 8080 which in turn was necessary for the unmodified H17 code.)

I didn't know that existed for the H-8. Please elaborate. It didn't exist specifically for the H8. I bought two surplus 32K x 8 core planes and built my own interface, first on the prototype board and later on the "wire-wrap" board but using solder. I had to modify the core boards so you could defer telling them whether you were reading or writing until half way through the cycle. (Normally they latched the read/write line at the beginning of the cycle.) Oddly, the core boards were very sensitive to interference. Turning a lamp on near them would corrupt a few bits. (Maybe that's why they were so cheap.) When I switched to a Z80 the interface (which exploited 8080-specific timing signals) would have needed some significant changes and probably could never have supported 0 wait state operation again, so I switched to a 64K DRAM board whose price had by then come down to a reasonable level. I gave the core boards to a core collector years ago, but I still have the interface. I was thinking of stripping it to recover the wire-wrap card.

The first item is the ZCLK from FBE Research. It is a real-time clock module - you remove U114, plug the module in where U114 was and then plug U114 into a socket on the module. I just have the module and a 5-1/4" disk which apparently has drivers on it. No written instructions. The 2nd item is a ZMAX - Z100 motherboard memory maximizer kit by Rick Pegg and produced and marketed by Graymatter Applications Software. Works only with later module Z-100 motherboards, does include written instructions for the modifications, the 6 specialized chips required and 27 (3 banks x 9 ICs per bank) 256K bit D-RAMS.

To change from 3 banks of 64 to 3 banks of 256 all you |needed to do was change a PAL or two. The newer machines also supported an |8MHz 8088 instead of the 5MHz part that most machines shipped with. I had one of the earlier mother boards. I replaced the 8088 with an 8MHz V20, but the fastest I could get it to run reliably was around 7.2MHz. I never looked for the bottleneck. |There |was a formal upgrade kit from Heath that included all of the parts required |to do both modifications. No cuts or jumpers were required, just chip |changes. Which makes me question the point of ZMAX, since it only worked on |the later (2806) motherboards. That's what I was wondering as well. Even on the older mother boards you only needed to change one PAL (if you wanted to he really neat) or raise the pin on the existing PAL. I can't remember having to cut any traces (just add the jumpers) but it was a long time ago...

Bob, I've got what I think is a full set of the Staunch 8/89'er (#1 - #30/31) and as soon as I can get it done I'll be OCRing them. If you'd photocopy what you've got and send them to me, I'd be happy to reimburse you for the copy and mailing fees. They'll end up on my retroarchive.org site. tnx.. g. -- -- "I'm not crazy, I'm plausibly off-nominal!"

Message-ID: <039501c6625b$3f2fa1b0$6501a8c0@NFORCE4> Hello all, I just received the following in my email: I'm trying to clean out my garage, and it's full of old computers. Do you have any interest, or know of anyone in the bay area (I don't want to ship) who might have an interest. Two heath H89's, one which I believe was built from spare parts. I don't believe either one is working right now. The "real" one has a graphics board and floating point chip in it. I have numerous disk drives and external enclosures. CPM and HDOS software, although I have no idea if the disks are still readable. Documentation as well. Numerous Z100 computers, two with internal monitors. Some have hard drives. One external monitor for the Z100. I don't know the condition - they have for the most part been in the garage for a long time. Software and documentation. [.] An old Altos system with two 8 inch disks. If you are in the SF Bay Area (or are able to get here) and are a collector who wants to use the adopted equipment please feel free to contact me and I'll put you in touch. The current owner is more interested in space than money so the items will be cheap to free for those who will put them to good use. All the best!

Message-ID: <20060419001550.RKFZ29406.eastrmmtao05.cox.net@[172.18.52.8]> Erik, Thanks for your offer of assistance in distributing antique hardware. I am not a SF resident, however I have an idea for obtaining hardware with a minimum of effort on the contributors's part. I need H-17 and H-47 drives for my H89's. If I sent empty boxes, sized to fit the hardware with the proper postage attached, the contributor would only have to load and seal the the box and put it in his mailbox (or drop it at the PO). If you think this idea has merit, please let me know. I am willing to pay for the hardware and the trouble.

I've suggested in the past that people upload disk images even if they are already in the library to have a way to confirm the image integrity. If someone else has a copy of this one to upload, that would be great. Or maybe the original poster might try rescanning it. -- Steven -- Delivered by the SEBHC Mailing List From RONALD.S.WEST at saic.com Fri Apr 21 08:29:57 2006 From: RONALD.S.WEST at saic.com (West, Ronald S.)
