IIe potential RAM issue

Submitted by SportBikePilot on August 18, 2025 - 7:49pm

I've got a IIe with logic board part number 820-0064-C. It appears to be a non-enhanced version.

 

When I hold down the apple keys and power on, it shows "RAM:" and sits there. ONE time I was able to get "RAM: F13 F12 F11 F10 F9 F8 F7 F6", but that doesn't much make sense. I can't get anything to boot properly either. Comes up to the Apple ][ display and the BASIC prompt but won't boot anything off of disk completely.

I am in search of a keyboard for this computer

Submitted by jwg1962 on August 17, 2025 - 8:50pm

Well, I am going to take a shot here, but I think it is a long shot. 

 

So I recently aquired a Med Fly Apple II clone with 2 disk drives.  However, the folks I bought it from could not find the keyboard for it. 

 

I am in search of a keyboard, can anyone help or point me in the right direction?  

 

Thanks,

Jay

II gs problem!

Submitted by Jiroplas on August 16, 2025 - 8:27am

I have a very cool program with which you can install different bootloaders for Apple II gs but I can't run it! It seems that the SYS files do not want to run on GS at all. But this program is very important to me! Can someone tell me what to do with it?

Are there any rotate user defined character routines out there that rotate say 8 degrees at a time?

Submitted by the444 on August 15, 2025 - 11:51am

i want one that does it in 8 degrees or so, clockwise and anticlockwisei dont mind if the edges get cut off when it rotates, btwany ideas?i know that i would probably have to use shearing to do this, which would be fasteri also know that i would use 256 segments instead of 360 as the c64 deals with this number alot better, so it would be 32 segments at 8 degrees each

 

in basic also

Single 27C256 or 27C128 for both Enhanced CD and EF ROM

Submitted by loderunner on August 14, 2025 - 1:09pm

Hello all,

      I am attempting to upgrade my Apple //e to Enhanced.  besides the 65c02 CPU and 27c32 DIP24 EPROM(for video ROM), I also purchased 2 27C256 DIP28 EPROM.  I programmed 27C256 EPROM  with a combined ROM image I downloaded from archive site. but after plugged them in, I only get 4 (or 5?) horizontal bars.  So I am wondering if this single EPROM approach works at all - do I need 2 EPROMs for CD & EF?

 

Here are some additional information:
