Use BasiliskII to emulate a Mac under XP. The version that I've found
works best for me is at:
http://gwenole.beauchesne.info//en/projects/basilisk2
All you need is a copy of your Mac's ROM and an image of a HDD with a Mac OS.
Be warned though, once you see how fast a 680x0 Mac runs under emulation on
a fast machine it's hard to go back to the real Macs. Recently I pulled my
MacIIvx out of storeage and was shocked at how slowly it ran. It was nice,
however, to see again how much functionality could be crammed into a
program << 1 Mb in size

Hi folks,

Surely the easiest way is as follows:
1. First, download the .smi disk images from Apple for system 7.5.3.
http://www.info.apple.com/support/oldersoftwarelist.html
There are 19.
2. All the disk images *are* bin files. If you go here:
http://wiki.oldos.org/Mac/68kEmulator
You'll find info on Stuffit Expander 5.0 which can expand bin files and
copy them to 1.44Mb floppies.
You only need the first two steps to start converting disks.

PS. Gosh I realise I'm really fortunate, I can ftp straight onto my Performa 400 via its Ethernet card and if I can't do that, I could use a Zip drive.

Sounds unlikely that they indicate ECC errors if the are on most of the
time, even if dim. Access seems much more likely.
> Is it the memory board or the memory controller that sets the checkbits ?
It is the memory controller. The board itself is a pretty stupid array
of memory cells. Even ECC isn't handled on the board, if I remember
right, but is handled by the controller. The board just gives 39 data
bits for every 32-bit word.
And at startup, every memory board is accessed in parallell by the
controller to initialize the ECC bits. So they should all be glowing
brightly at startup if it is an access indicator.
But in that case, I would expect them all to then turn off as no memory
access will be going on after that, until the machine boots.

That makes sense. If you remove any board in the middle, you get a weird
hole in the memory map, which is illegal. The board at the left end is
the last board, so removing that one isn't a problem. You don't create a
hole then, you just reduce the amount of memory you have.

Programs like Media Master can read and write Kaypro disks on a PC, but in order for a disk to be readable, it must be formatted on the PC (same goes for a Zorba disk).
The following is the explanation from the Media Master Read.Me file:
<quote>Both the Kaypro 2x,4,10 (DSDD) and Zorba 40 trk (DSDD) formats have a
peculiarity that prevents you from using a disk that is created on
the "native" computer.? In both cases, the only way to transfer files
is to first format a transfer disk in the Kaypro or Zorba format using
MEDIA MASTER and your computer.? Then use the Kaypro or Zorba computer
to transfer files from the "native" disks to the disk you created with
MEDIA MASTER.? Then using MEDIA MASTER, you can transfer the files to
any format you wish.
Another way of viewing this problem is that disks created on the
Kaypro 2x, 4, or 10 can only be used on the Kaypro 2x, 4, or 10, but
a Kaypro 2x, 4, or 10 disk created on your computer with MEDIA MASTER
can be used on both your computer and the Kaypro computer.</quote>
BTW, I have copies (for MS-DOS) of Media Master and Convert (1984, Selfware, Inc., Charles W Woodford). Contact me off-list.

They are all S-100 cards. One is a North Star floppy disk controller, the
others, I think are all memory cards (two are Seattle Computer Products, one
is Vector Graphics, I'm not sure about the last card).

There are all s-100 boards. It looks like (2) 16K Seattle computer Products boards, a Northstar single density floppy controller card, and an unrecognizable static ram card (to me at least).

Yes, that seems reasonable. The puzzling thing is that on all the boards, the light stays on, just less brightly, after a few seconds.
Is it the memory board or the memory controller that sets the checkbits ?

Can't tell yet; I have some other issues to resolve with the machine before I can get to normal operation.

No, they're soldered in.
Each one has a switch that I believe allows you to take the board offline. I can take any board offline (which throws a red memory configuration error lamp on the memory controller) except for the board in the left-most slot, no matter how few or many of these things I put in there.

Can anyone tell me what the yellow LED signifies on the EMC 1MB memory boards that can be used in the 11/750? The EMC part number of the boards is 240-011-900.
The green LED appears to be for power but I'm curious about the exact meaning of the yellow LEDs since they start out bright, on powerup, and then dim quite dramatically after a few seconds, presumably after or during initialization of the boards.
Thanks,
-Dave

>from the site "Every year [Len Bales] designs and builds a new clock. His 2006 clock runs on the classic Intel 8008 microprocessor. The design is definitely not for the faint of heart, but he includes all code, diagrams and a good description on his site. The project is an interesting look into the not-so-distant past of computing. While the function of the project is a clock, it is actually a fully programmable 8008 computer running at 500khz with 16k of memory space and 4io ports.
