After the NC4000 was created, many realized how easy it was to create a Forth processor with the newer technology in ASIC or programmable arrays. I wonder what has failed on your board. If it isn't the chip, the rest of the board is relatively standard parts. These Forth board were often used as accelerators for PC systems. Several test that showed that these simple processors could run application more than 10 times faster than similar clocked x86 or 68K machines of the time. The RTX2000's were made RAD hardened and used quite a bit in satellites. Much of the speed was because Forth lends it self to a 3 bus architectures that functionally used at least two of these buss on each instruction.

I don't agree in this case. While I usually don't bother, since he's mostly into RT-11, which I haven't used, we're in rather separate worlds. But his assumptions about Mentec are just assumptions. > I should point out something that you dont seem to be aware of (at least > based on your statement above) - a demonstrable pattern of non-enforcement > of license does in fact weaken the ability to enforce it.

Yes, but this is all based on the assumption that the company is aware. Otherwise it's not a point at all. So you should then first of all demostrate that the company *is* aware, and haven't bother taking action. I haven't seen that proven yet, and I'm pretty sure you haven't either... For the company to be aware two criteria must be fulfilled: 1) Mentec must know of this list, and monitor it. 2) People on this list must in no unclear terms make it clear that they are breaking the license agreements or violating Mentecs rights. And as I said before, I haven't seen either of these two proven yet. But to make it easier for Mentec (in case they are looking), how about a head count. Anyone who is using Mentec software without having a correct license: let us all know. Make a public reply to this. That will atleast fulfill one of the two requirements (if anyone will reply to this call out.) > This is also one of several reasons that some - not all - companies are wary > of creating a hobbyist license, because there is some amount of perception > that it will put their ability to enforce a license at peril - or at the > least possibly cloud the issue. Yes. That is true. > On a separate and unrelated point, I believe Johnny (or someone) questioned > whether Mentec is aware of this list, various archives, etc. I can assure > you that they are, just as Jerome intoned. Really? And how do you know this? Just because one ex-Mentec employee occasionally post here, do you think that Mentec knows about it? For all that I wish that a hobbyist program was available, none exist at the moment, and actions and false beliefs like this is likely going to keep preventing it from ever happening... Call me Mr. Negative if you like. I just try to point out things as I see them. You may all disagree. Can't help that. Atleast I got valid licenses. And you can have that too, if you pay for it.

FPGA designs Which reminds me back in 1987 or so I bought a NX4 single board computer that ran Forth was that a FPGA design? it had a Mostek MKGD02TG as far as I can make out from the picture. It failed some years ago when I last had a play with it. Dave Caroline pic at www.archivist.info/computers/nx4.jpg

WANTED: Mac SE/30

by dgriffi＠cs.csubak.edu

Does anyone here have a Mac SE/30 in good working order? I'd prefer one with little to no yellowing, keyboard, mouse, a good crt, and good floppy. Hard drive is unimportant as I have plenty of suitable SCSI drives. Extra memory would be nice too. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

8mm data cartridges

by aek＠bitsavers.org

> I always figure there's a lot less to go wrong in a DLT cartridge than there > is with a hard disk The flaw in this argument is the time it takes to make another copy, which needs to be done at some point to migrate to newer media. You will only know the DLT has failed when you try to read it again. If you care about the data, it should be kept in a form that is easily replicated and verified, and you should assume that any single copy of that data WILL become corrupted or unreadable over time.

OS/8 on-disk structure

by dbetz＠xlisper.com

Does anyone know if there is a scheme for mapping out bad blocks on an OS/8 RX01 disk? I have an image of an RX01 disk that I'm trying to retrieve data from and it seems to have bad data in the middle of a file (4 blocks). Is there any chance these were bad blocks that were mapped elsewhere on the disk? Thanks, David

SC/MP LCDS

by sttaylor＠charter.net

First time post, I to am surprised and pleased to see the Scamp get some post time. I hope you will archive all of the LCDS Kit Documentation you have. (or send it to someone that can archive it) There is VERY LITTLE documentation (and no Original Natl. Semi. Docs) on the net. It looks like more people then you thought will be watching Ebay for your SC/MP auctions. Steve
