Recently back to old skool retro!

Wellll, i bought some goodies from gotek.nl
A new SUB-D(23) to scart video cable for amiga.
A 9pindin mouse to PS/2 convertor
A switchless (using key combination) diskdrive switcher df0<>df1
I used to make a floppy switch myself in the past, i used a wirewrap socket, and a cross switch. Made a hole in the back, with the little switch.
This one does not need a hole in your case for the switch.
Gotek Floppydrive Emulator with Rotary Encoder
This drive supports a lot of disk formats and systems, i will have to look into that ..

Update: 20220514 – Vic Graf cartridge and more
Manual : https://archive.org/details/VIC_Graf_1982_Commodore/page/n11/mode/2up
I’ve got a load of cartridges, some of them i tested:
As posted before ( https://www.henriaanstoot.nl/2022/04/09/c64-plus-drive-running-again/ ) i’ve got a little gadget which emulates a C64 diskdrive.
I’ve been using this for a while now, and i’m really impressed by it. It just connects to the Serial Din of your C64, draws power from the Cassette port. … And even looks like a mini drive!
I’ve been converting Disks to images as well as runnig previously converted D64 images on a real C64 again.
Also the internet provides loads of images to run again.
Converting and running:
There is a disk selector and run program you can use. (See below)
Also you can use the buttons for disk swap/change.
One from my collection: A training kit for learning to write machine language.

Update: 20220829 – Mad-1 computer runaway movie
A little example, life programming a little machine code.

Using a tape and COMX-35 cassette player, i can store and retreive programs
Above i mentioned a Runaway Cameo .. well there is a MAD-1 system cameo also. (Which also i in my collection)

I found a cassette tape yesterday. I was really curious .. dont remember making this.
Connected a tape drive to my C64 and tried to get the damn thing to read the tape.
Got stuck on READY’s with no programs. Being a little rusty into using C64 i tried:
Maybe there was a turbo loader used?
Maybe my tape unit wasn’t aligned?
Tried multiple tape units, couldnt find a Tape Head Alignment Program like:
So i used another method to see if data was recoverable.
Using UberCassette or AudioTap
Above are two examples with uses recorded wave files and calculations to generate the original written bits!
Recorded the tape to mono wav file using a generic linux recording application.
ubercassette taperecording.wav mytape.tap For my amiga i started to build a floppy disk reader/writer using a arduino.
I found a superb project by rob smith.
It uses only a arduino pro and a FTDI USB to serial breakout board, to raw read and write disks.
I wanted to convert my own created amiga disks to PC image to use in a emulator like vice.

I’m not going to copy his website, with all instructions. Only my personal experiences.
Starting with … don’t use a IDE cable, and start soldering .. it is a diskdrive cable .. connector doesn’t fit! ..
Getting components and flashing arduino … no brainer
Got a working amiga again. \o/ woot
Needed to replace Paula chip, cleaning and some TLC.
Scart cable i’ve got is one without the resistors, so my monitor isn’t detecting the signal.
Using a A520 modulator works. At least RF, don’t know why RCA/composite video isn’t working.
Even a memory expansion and second drive (5.24 inch) are working.
To do:
Disks to convert:
Got another one running today also:
20220502: Fixed another C64, PIA (Peripheral Interface Adapter) was dead, luckily i’ve got several spare-part c64’s. So that was a easy fix.
20220504: Got my sd2iec adaptor in, see bottom of this page.
Drive is a 1541model 2
De wires are going to the DOUT pins of the memory chips. Showing activity using leds. Sometimes i monitored CS .. also informative.
SD2IES Cardreader
Little small funky gadget, it replaces a 1541 Floppy drive with a SDCard reader where you can store a lot of floppydisk images on.
More on this later.
NOTE : Doesn’t work together with my KCS Power cartridge.
I’ve tested two cartridges.
Final cartridge III fastload test on a program did ~3 seconds. ( Normal load time ~17 seconds. ) KCS powercartridge didn’t work. Tip: press `runstop` when using FC3 while turning on to get into basic not the desktop.
