 | Well Here it iss in May 2021. My Stock Amiga 1200 (as stock as it can be wilst biffing it up on many levels to keep it looking SOMEWHAT original) A long haul for sure. Its an amiga 1200 with Original Amiga Kickstart roms from europe. NTSC model. It has the mxb 1200z 8mb accelerator + RTC board installed in the trapdoor. It has a new 220 dollar retro non yellowing case from a1200.net that has been custom vintage grey and clearcoat painted. I retrobrighted the keys and had to replace esc key and a couple others. I added the ide to minisd adapter with a 32 gig minisd card. I added a buffered RGB to vga adapter and a Tom+ serial to usb + extra serial Adapter from my friends over at ELECTRONICA4U (on ebay) Great folks btw. They'll never let you down. I modded and did the pin flip on a Sega Genesis controller to allow multibutton functionality on the amiga with an expensive joystick as the second shared joystick port. Through the tom+ adapter i added a Lenovo usb laer mouse and a Dell hd led lcd monior that supports 15-22khz vga analog signals with the Crystal Phase and Shift OSD adustments. This lcd monitor allows for frequency adjustments on the osc which allowed me to dial in the frequency to match perfect with the amiga rgb port!!! I developed and got os3.9 going flawlessly on an emulator in my windows environment over the years using WINUAE. which i later ported over to my amiga sd card. (KEPT ALL THE DOCS IF ANYONE NEEDS) It was a hard journey. I like flare i like eye candy I am a power user and like a full featured desktop. With whdload i was able to run all my old favorites but as you know. EVERY old sk00l amiga user is all about memory and conserving memory and making the system as efficent as possible . Me not so much. I like the look of it. Having worked on windows for so long but being 46 yrs old and starting on commodore i Simply cant run that was. I needed a fine ballence. Functionality flair beauty and efficency with high mem yeild . I have finally tweaked out my os3.9 as i simply didnt like the look of a bare bones BETTER WORK BENCH 3.14 system. It just doesnt look good to me. I found ways to invoke the blitter system for graphics and reduced color depth and size of my background and doc bitmaps aS WELL AS THE ICON LIBRARY to get me 1.8m on chip ram and 5.2meg on fast ram expansion 7 meg and change. enough to run 90% of everything smoothly fully featured. It was then that i learned about the whole aga and chunky planar optimizations and started playing with 3d ports of games learning that chunky planar dos games run ALMOST natively at full speed to the amiga 68020xcpu 1200. I stumbled uppon a program called RTGMASTER whicg drastically speeds up your games allowing them to run at full rtg speeds most of them. But some of the eye candy i wanted required 8meg of ram to run. and i was not about to drop my beautiful os3.9 install for some barebones 16 color piecew of ..... os. like the rest of the world has to do. So i spend a week figuring out how to cruch the base workbench and all its libraries and drivers to auto mount any file system on an 800k floppy disk!!! and YES. this weekend (after a coffee accident that almost ended the whole commodore venture) I have an 800k slim boot of os3.9 that runs on only 168k of memory leaving all chip ram avail and 7.8meg of fast ram for the big stuff like doom, blake stone, final odyssey, genetic species etc need to run. all on 800k floppy all the sound libraries low level, video drivers ands blitter for aga ahi and sound libs all patched in very bare bones but this was the solution i needed. All the flair and eyecandy i need in a system but in a pinch i slap in a floppy and i got the newest os ready to rock any game i throw at it on only 200k ram!!! the only downfall to this is that i cant get whdload on it only 150 k free. i will develop this more later using powerpacker to crunch the executables and MAYBE just maybe i will be able to fit the whdload a500 kiclstarts on the floppy too. then it will truely be a site to see. PS: if your trying to run old a500 games on your amiga 1200 using whdload and you do not have the memory NO PROBLEM: right click and edit the icon and in the tooltypes section REMOVE the PRELOAD and PRELOADCACHESIZE lines or bracket them. Almost all games will load . the only annoyance with this is that when certain disk access routines happen the game needs to switch to desktop mode so you get a screen swap to desktop. its a flicker . a bit annoying but.... ALL games will run as your not trying to preload the whole game in memory. Using the PRELOAD option in the icon tooltype by itself uses the max mem avail to it. Using the PRELOADCACHESIZE=xxxxxx allows you to specify how much ram can be used to preload files to stop the emulator frow swapping screen modes to the workbench ot load certain files (IM WORKING on a library that will do these swapps off screen in memory so that you will no longer see this flicker. This will take some time ill keep you all posted) see my pics below. [link] [comments] |
