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:

Apple II+ - can't get to BASIC prompt

Submitted by SportBikePilot on August 13, 2025 - 6:24pm

Hi All,

Some time back I inherited a complete Apple II+ system with language card, parallel card, Hayes modem, Serial Post, Z80 card, and Disk II controller along with the monitor, disk drives, printer and software. 

I finally got around to replacing all of the capacitors in the power supply (thanks Console5), and cleaning the system up.

 

When powered on, it tries to boot from disk. I can successfully boot into CP/M, as well as some games, etc.

Does anyone have the contacts for Tom E. Hawk or The BOY! ? And Doug Cuff and Morgan Davis? I'm looking for these people to ask about viruses for my little museum.

Help with proRWTS

Submitted by VIBR on August 9, 2025 - 2:46pm

Hello All, 

I continue my work on the smartloader for the smartdisk II, the current version uses prodos and before starting smartloader it fully loads prodos.

My goal is to optimize the loading process, my new approach is to use a custom bootloader and to use DOS3.3 RWTS.

My initial tests are good and it is working I should be able to have evevrything on track 0. 

DOS3.3 RWTS is not optimized and not fast. 

Searching on the net, I found proRWTS2 from Qumba, and I am looking for support to implement it.

My understanding is :

Apple IIGS not responding to keyboard

Submitted by DistantStar001 on August 6, 2025 - 3:37pm

Just as the title says. I have an Apple II GS that is not responding to almost any keyboard inputs beyond reset.

Note: for some reason, this board was modified or came with the connectors for a Stealth GS despite being in an original II GS case. 

So far I have tried 3 separate ADB and one //e keyboards with the same results. All keyboards have been tested on other machines with no problems.

Applied Ingenuity Hard Drive/PSU Questions for IIGS

Submitted by DistantStar001 on August 6, 2025 - 3:27pm

I recently got an Apple IIGS with… shall we say, issues. But that will be another post. Inside, however, were some pretty cool upgrades including an Applied Engineering RAM GS card with the full 1MB onboard, and an "Inner Drive 40 High Performance Hard Drive System."
