512k's, 512ke's, Pluses

Recommended Posts

25 compacts of varying configurations from stock 512k's through Plus, including several 512k's with SCSI and one with what I'll assume is an external display adapter of some sort. None are in all that great of condition, no keyboards or mice.

I'm thinking I first need to do some nifty project incorporating all of them. Localtalk based 5x5 display grid? A gigantic pseudo iphone? Then I dunno, maybe come up with some kind of contest and send some home as prizes or something.

Final tally:

128k: 1, working

512k: 6, 3 of which have dim/nonfunctional displays

512ke: 9, working

Plus: 9, 1 of which has nonfunctional display

 

Other notables:

3 of the 512k's have MacRescue's on them with DB25 SCSI ports in the battery bay. 1 of them isn't booting, probably because of a mis-seated MacRescue

1 of the 512ke's has a DB9 coming out the battery bay

1 of the 512ke's has a hole in the back with a BNC connector

1 of Pluses has an amber monitor

 

Looks like I need to plan an analog board revival party.

ok where did you get these bad boys? And How much did you have throw down for them?

 

also did you get keyboards and mouses with those?

 

if you would like to sell me a keyboard you can pm me, other wise ill leave you alone, to bask in your compact mac goodness.

ROM booting Bolo LAN party!

The DB9 video connector goes to a passthrough adapter that sits between the analog board connector and the logic board. There's also a clip that goes off to the LS04 chip next to the ROM.

It is labeled N^2 Products, I believe.

 

There are no Platinum 512k's AFAIK, and all the 512KEs are M0001E's. The 512k's are all M0001W.

Baby steps towards doing something interesting: I've got an appletalk server that broadcasts out events (mouse location, mousedown/mouseup, keydown/keyup, etc) and a client that listens to it. The mouse tracks ok, and key commands to manipulate menus work. I have learned something neat about the menu manager though. When you mouse down on the menubar (or a menu), 1) the menu manager doesn't refer to the mouse location in the mouse down event, it looks at low memory globals to determine mouse state, and 2) it doesn't return control back to the app until you mouse up. I have clicks in the menubar working, but mouse movements such as click, drag down on the File menu, select an item, mouse up, doesn't get any of the mouse movements while the mouse button is down in the menubar. The way to fix this is to be able to send my appletalk packets from an interrupt handler, but I'm using the eeeearly appletalk API documented in IM: Volume II, which isn't safe to be called from an interrupt handler. It is possible to bypass the API and talk directly to the appletalk driver, but that ends up being a bit tedious. Anyway, all of this is to be able to run on the 512k which don't support the newer APIs introduced in later System releases.

 

Ah well, blasting out events to two dozen macs and having them all track the mouse movements of a single machine is neat and all, but lacks a certain... pop. It doesn't pop. It needs something more.

Amber and green on black were considered easier on the eyes than white on black in the Neolithic .TXT era. It was a rare treat when I got a Page White TTL Montor for my SignMaking Workstation back in the day.

 

On a computer bundled with MacPaint, only Black on almost white for the first available WYSIWYG GUI experience made any sense at all. Generic CAD and CorelDraw worked fine with a Hercules Graphics Card driving on an Amber CRT and was much better for Object Oriented Graphics than were Macintosh display resolution of the era for graphics , but not nearly as nice looking.

 

Additional suggestions for POP!

 

Put'em on shelves with each being mirroring sections of the singleton's desktop like you said. But simplify it by having each pick up and take up the moving position of the enlarged cursor, with the proper delays for movement of the cursor over the sparse array. Each member of the chorus ignoring the rest of the Band leader's screen content while playing individual musical note alarm sounds, mimicking a Synthesizer?

 

Gonzo bonus points for having the Band Leader mimic a player piano by ImageBanging musical notation on fanfold paper . . .

. . . and then playing it back via ThunderScan.

For anyone else who happens to be doing development for these really old systems, CodeWarrior's application glue (the stuff between double clicking and when main() is entered) unconditionally calls StripAddress on the pointer to your code resource before jumping into it. These older systems don't support StripAddress, so you get an unimplemented trap even before entering your own code.

 

THINK C 5 generates code that works. I'm using System 3.3 (the appletalk one!) for testing on the 512k's.

Nice!

 

The University of Texas at Austin used to sell lots like that at their warehouse on the Pickle Research Center, until the state Leg. changed the law so all the surplus stuff goes to the prison system. Sigh.

They look ready to march into battle.

Yeah, I hear Vader's March every time I look at that image :o)
