Apple II+ No Video, yet Boot is OK

Submitted by whynotpizza on May 6, 2016 - 9:54pm

Hey guys,

Trying to get an Apple II+ working again and can't seem to figure out where to start.

The machine has a Language Card and Disk ][ Controller Card and nothing else.

Power up "beeps" OK and disk activity sounds good, appears to boot into DOS no problem.

Yet there is no video at all.

I am using Amdek Color-I monitor which I know works OK from another system.

I have tried removing both Cards and booting, yet still no video.

None of the chips on the main motherboard produce abnormal heat, and all chips/connections on the board appear clean visually.

Any suggestions on where to start?

Apple //e DHGR issue

Submitted by amauget on May 5, 2016 - 3:04pm

Hi to all !

I'm currently restoring a PAL Apple //e motherboard ref 802-0073-B.
It was modified at some point to be //c enhanced (65C02 with modified ROMs and extra wires).

I revert all the modifications and it works great except while displaying DHGR screens : there are verical lines.
Here are the screenshots.

All the IC seems okay (MMU and IOU are okay with another motherboard). I'm pretty sure it's a missing or bad connection.
I do have checked all the connections to the RAM (Figures 3.9 and 5.2 in Understanding the Apple //e). All good.

Any ideas ?

Thanks a lot.

Apple //c repeating character issue

Submitted by CWJ_Wilko on May 4, 2016 - 6:53am

I haven't used my //c in a few weeks, and tonight I've booted up and immediately hit an issue. While it will boot normally, a space character will keep repeating over and over, and the computer will not accept any other key strokes.

ID a part on the Apple II Video Overlay Card?

Submitted by Keatah on May 3, 2016 - 6:54am

I've got a cracked L3 on a video overlay card. Actually 3 cards with this same part cracked in the same way. It's the tan colored blobber-job thing immediately left of the square Motorola thing.

The markings are:
SDL - 4105
TDK - y

Anyone know of a source to get this from? Not had any luck finding it yet, and I fear its a long obsolete part.

Proterm and VT100

Submitted by jrubin on April 30, 2016 - 10:34pm

Im trying to decide whats going on here. My whole reason for moving to proterm 3.1 was that 2.1 seemed incapable of displaying VT100 correctly

Clearly my the codes are getting out there, as youll see below. whats the point of terminal emulation if it wont emulate? The only other possibility is that what linux is sending out is in fact not vt100

Uthernet Network Printer

Submitted by 6502enhanced on April 29, 2016 - 1:43pm

I know it is possible to use a printer in the network via uthernet with a IIgs - but is there a possibility to do this with a IIe or II+ also ?
