Trackman Marble on the Amiga

trackman-marble-galleryI wanted to see if any new trackballs still work with the Amiga, finding the Trackman Marble‘s specs it does say USB/PS/2 protocols.

So today I picked up this nice trackball. I plugged it into my Jerry+ adapter which takes PS/2 protocol mice (and trackballs) it worked perfectly. It didn’t come with a USB to PS/2 adapter, but I don’t need that for the Jerry adapter.

The Trackman Marble runs at a nice speed, and if you get used to using trackballs it’s a good piece of hardware.

The Jerry/Jerry+ adapters are like other standard PS/2 to Amiga adapters, works perfectly. The Jerry adapters has USB interface instead of PS/2 so you don’t need to use the USB to PS/2 adapter to use this. I bought my Jerry adapters off a seller on ebay I believe it is this guy. He might also be found on Amibay as well.

The price is really becoming for ~$30 as referenced on the Logitech website.

Below in the video I show the trackman in use. Though a little handicapped with the camera in one hand and trying to show the trackball together with the monitor in the other hand.


Super Bread Box – C64 Cartridge –

I love original packages, specially with nice contents.
RGCD keeps delivering some really nice packages, and now with small posters as well.
Super Bread Box Contents

The skulls didn’t come with the package.

It’s been a few years (2?) since I tried Super Bread Box, and I must say it’s quite simple but highly addictive. The same goes for Assembloids which I also have on a cart from RGCD.
The Deluxe package is definately worth it, and while this is my third (only, sorry James) that I bought, I definately feel the quality is top notch. It doesn’t have a keyboard overlay or a thick manual like the MicroProse games, but the general experience with the RGCD cartridges come close to those game boxes.
As you might have discovered, a huge part of my whole game experience is the box and contents. Hence I love games boxes from MicroProse, Goldbox series (Pool of Radiance series, Champions of Krynn etc) and more of this kind.
I have many fond memories of playing Mario Bros – the old platform game where you jump into the ceiling to flip over the monster walking on the level above you. Not only fond memories but laughable fun as well in two player mode. I can surely say I generally don’t like platformers, but there are a few exceptions, Mario Bros and Super Bread Box are a couple of those exceptions.
Now Super Bread Box is somewhat similar to Mario Bros, but instead of jumping into the ceiling, You start with a puny pistol which you need to use on killing the monsters comming from the top levels. What you actually need to do is get a certain amount of crates as possible to be able to exit the level only yo get to the next. Random spawns and random crate contents makes this sometimes hazardous for your health. You also get the chance of getting better weapons when you pick up a certain amount of crates.
Recommended is a joystick with a fast autofire for that puny pistol.
Otherwise turn it off 🙂
You can get the game on CSDB as well but really. Support the guys who made the game and buy it.
RGCD or Psytronik are the places to go for stores with original games these days.

DIY 5.25 inch cleaning disk

I’m dumping quite a lot of disks in different formats. For that I’m using the Kryoflux, but quite often are the disks dirty, and the dirt gets stuck to the read head of the drive.

I’ve shown how to clean a 5 1/4″ diskette before. And how to clean a Commodore 1541-II drive (the other models are quite similar).

The PC diskettedrives are no different, but to be honest they aren’t as easy accessible to clean when inside an enclosure as the stand alone commodore drives. I found in a forum -at writing hour I cannot find the reference again, sorry, I think it was vintage museum forum- how to make a cleaning disk yourself.

I’ve tested this method myself and very happy to have my drive cleaned again. One of the heads were dirty, real dirty, nothing could be read from the disks I tried.00_filthJust look how much filth I removed using my first inlay. Now here’s how to do it.

01_cut_openTake a disk and gently cut open the back. I recommend you take an already defective disk.
02_remove_discPull out the magnetic disc.
03_cut_out_inlayPrint out the template (download link below), or you can make your own. You can use regular printing paper for this. Alternatively you can use coffee filters (don’t print on these).


Insert the new inlay into the disk.
05_disk_readyMake sure the rotation hole is clear, else the spinning might tear up the paper.

06_add_IPAI’m using a straw as a pipette, a few drops of isopropylalcohol on the paper where the drive heads read the disk.

Insert the disk into the drive and close the lock. Make the drive work it’s head back and forth. If the disk drive is connected to the computer natively you can do a directory listing, or a disk copy which should move the head back and forth.

For the kryoflux setup a calibration test is great. Reading from the disk just makes it tell there is no disk in the drive.

I have yet to find an amount of cleanings one can do with these inlays, but depending on the amount of dirt that rubs off, you may want to change them often. I’ve tried 5 cleanings using the same paper, but at one time the paper will break.

Disclaimer: I take no responsibility if you break your drive using this tip. It worked for me, but might not work for you.


Tapuino now built into a C=1530 cassette deck

Thanks to Lars Møller who was so kind of donating a defective Commodore 1530 cassette player. Internal mechanism didn’t work, and the buttons was missing. I already had 2 tapuino v1.4 boards of spcbm (amibay) and of course the whole Tapuino concept by sweetlilmre / Peter Edwards. And I was meaning to do this anyway, put a tapuino into a C1530 that is, receiving a broken device was something I was waiting for, no way was I going to sacrifice a working piece of Commodore equipment.

At this time the internals aren’t finished, I still need to fasten the mainboard, cut a hole for the tape connector, and maybe even one for the usb head. I’m also considering to add a fake set of buttons, perhaps printet on a 3D printer.

Well for now things work as intended. Hotglue was used, a little too much and I had to replace 3 tactile buttons. The LED wasn’t supposed to be this one either. I had an other one which I moved the variable resistor for the contrast out, this was supposed to be set into the hole where the azimuth adjustment screw was supposed to be.

Enjoy the images and video.

GVP HD+/HD8 with Card reader

Recently I aquired a GVP HD+ without any shell. It works perfectly and has 8 megs of ram on board.

It came with a Quantum ProDrive LPS 50MB, unfortunately these old drives have a habit of getting bad blocks, I have 3-4 of these drives, all bad. The drives also “sing” while on. So it’s very noisy.

Quantum ProDrive LPSI found a very small Compact Flash card as a test to replace this drive.

32MB Compact Flash card

So here’s the setup with the SCSI Card Reader connected to the GVP HD+

A500 with GVP HD+ and SCSI Card reader

The SCSI Cardreader which I got off -the now dead- store (the link points to the wayback machines copy of the site).

SCSI Card Reader


And it works perfectly using the GVP FastPrep software.
Prepping a CF Card in SCSI Card reader

So the endresult is a silent GVP HD8+/HD+ with a card reader and easy access to the cards.

A note of the card reader is that each device is attached as LUN’s so If I have each type of card, I could have as many drives. The card reader takes Compact Flash, PCMCIA (the PCMCIA to CF works also), SD/MMC, Memory Disk and SmartMedia.


SCSI to SD adapter – Open Source

scsi2sd_4.2-500x500A guy on facebook posted a link to this device. It’s a SCSI2SD device, meaning that you can insert a micro SD into this, and attach the board to a SCSI bus.

This is great for a lot of Amiga systems as SCSI drives in 100% top shape are hard to come by. A lot still works, but the “singing” of the spindle is just annoying.

Adding this to a GVP HD+ and similar devices makes it possible to remove the internal fan wire, so that won’t make noise either.
