I wonder if anyone has the boot disk for this system? I have them buried and can't find them and need to boot the system for a project sooner than I'll find them. Thanks Jim

AS/400 available for pickup (UK only) [Second call]

by classiccmp＠memory-alpha.org.uk

If anyone within striking distance of Birmingham (UK) wants an AS/400, I've got one which you can have for the cost of coming over and taking it away (strictly pick-up only, it's far too bulky to post). I believe it's a model 9404, with an expansion cabinet - each cabinet is similar in size to a DEC BA123 cabinet, IE not massive, but big enough.... And that's all I know about it, I've never even plugged it in! Contact me off list if interested. Thanks. Alternatively, does anyone have an address/phone number of a UK based IBM dealer/scrapper who'd come and haul this machine away (there's currently a skip located two houses down from where I live, I'm resisting the temptation for now....)? TTFN - Pete.

Let me see what I can do. Wow, Rob. That would be fantastic. Thank you. Please let me know if there are any expenses related to duplication for which I can reimburse you. Jeff

You are correct and I have that. But thank you, because I might not have been aware of it. You had no way of knowing. I also have "Guide to the Macintosh Family Hardware", and the Inside Macintosh series. If I was an experienced video card designer, that is all that I would need. They explain the interfaces, more or less. But I would also like some materials that would teach me something about the art. For example, there are a number of different ways to handle updating the frame buffer so that one avoids artifacts on the display. What are the pros and cons of each and how do they apply in this particular situation? I could try to build cards for each of them and test it out. But I probably can't afford that many proto-types. On the other hand, I might be able to get several designs out of one or two prototypes by making good use of the flexibility of FPGAs. Still, I'd love to read about some designs that worked and see what choices other folks made. >> One specific thing I've been wondering about is how one implements >> quickdraw acceleration.

Cool. Thank you for the ideas. I will look at those commands and develop ideas on trapping and accelerating them. Jeff Walther

Hawthorne 68000 SBC

by rcini＠optonline.net

All: I just got a complete working Hawthorne Technologies 68000-based SBC. It?s a 5.25? form factor computer based on the 68000 CPU. It has two serial ports in addition to a floppy controller which is PC-compatible - it uses 360k diskettes and PC drives and the disks can be read-written on a PC. Among the disks provided was an editor, debugger, assembler, and Forth. What it doesn?t have (that I can see) is a C-compiler. Does anyone have this SBC with a C-compiler? BTW, I made disk images so if anyone needs them, I got ?em. TIA.

Anyone knows of websites discussing true junkbox CP/M systems ? The P112 might be nice, but my junkbox contains only the standard Z80... Jos Dreessen

Available FOC Winman 4x4 EISA MIDI I/Face.

by austin＠ozpass.co.uk

Hello all, Just been sorting through all my junk as part of a spring clean. One ?sort of on-topic? item that seemed too good to throw away is a MIDIman Winman 4x4 MIDI interface on an EISA card. Pictured here (warning 4MP image): http://ozpass.co.uk/files/Winman-4X4.jpg The card offers 4 in/out MIDI channels and was pulled (a long time ago) from a system running Cubase VST on Windows ?98. Functional to the best of my knowledge. If anybody wants the card it?s yours free-of-charge (excluding cost of delivery). Let me know off-list. Regards, Austin. P.S. Based in Manchester, UK.

8-bit (S100) question

by jack.rubin＠ameritech.net

I'm building up a demo S100 system for VCF. I'm considering using a modern switching power supply for regulated power and abandoning the onboard voltage regulators on each card. I know the last CompuPro boxes took this route so it must be feasible. What is the general wisdom/experience with this approach? Thanks! No virus found in this outgoing message.

Jay, perhaps you don't notice this because the type of things you're most interested in - old HP and DEC gear - are still actively discussed. But discussions of the small stuff: 8-bit micros, CP/M machines, Apple Lisa's, HP Series 80, etc., have all but disappeared. There used to be a pretty active discussion about these sort of machines on the list, and a lot of resources to draw on, but no longer. Posts about those sorts of hardware are few and far between and are, when they do occur, usually generate no threads. As I previously said, that's an observation/conclusion, and other are entitled to agree, disagree or vituperate, but I think it's backed by empirical evidence. Some may not like the conclusion, or claim it's incorrect, but this is something I've observed for at least a few years and I have a lot of archived posts that seem to bear me out. I thought it was pretty obvious that I was using an example - in this case the relative response to the Linux post vs. the Kaypro post - as an example of a general trend. Naturally, the naysayers, serial disagreers and chronic debunkers conveniently ignore the obvious and pretend that I am trying to draw a broad conclusion from a single occurrence, even though they know (or damn well should know) that's not the case.
