Re-implementing Minesweeper for the PDP-8 (and others)

This thread over at the Australian Computer Museum forum is worth keeping an eye on: Marcus is writing ports of Minesweeper for various historical machines, starting with Mac and IBM 5150 (bare metal, 10 floppy sectors), but heading towards the PDP-8 (using as little paper tape as practical, for convenience of loading)

Code is here

Looks likes the idea is for teletype-style output (probably a glass teletype, given the need to keep printing out the board.)

Did the PDP-8 have a option for the same display as the for PDP-1 space war?
That might make a nice display option for version #2

There were options like that for the PDP-8. Partly the problem is that not many survive, especially in working condition. OTOH, they aren’t that difficult to implement. Basically a couple of registers (X & Y) and DACs to convert to an analog position.

The other problem, which may also be why relatively few were purchased or survive, is that each PDP-8 model seems to have rolled their own. That means there are ifdefs in spacewar and compatibilty issues in other games which use them.

Yes, you hook can hook up the later versions of the Type 30 display, the one that ges with the PDP-1, to a PDP-8 (while this probably requires an additional I/O module on the side of the PDP-8). There’s is also a video display processor (VC8) that hooks up to later screens, like the VR01-A.

That was nice about the old wire wrap computers, easy to interface any where.any time.
Now all we need a USB version, to go with all the Pie 1’s 8’s, 11’s and 10’s. :slight_smile:
