Crack a Mac

| January 14th, 2018

After seeing some carnage from expired batteries online, I decided to crack open my mac SE, and remove the on board battery.

Worlds cheapest crack a mac tool for getting those 2 under the handle.

A 1/4″ hex bit, a bic pen barrel, and a T-15 torx bit.

 

Watch this connector when you pull the board back. It is just long enough to get to this point, then you are out of wire. It is the little white connector next to the large molex power connector. I think it’s the speaker.

Lucky for me, the battery hadn’t shit its guts, and the board was fine.

 

Snippy – Snippy!

 

Plugged the scsi, lower floppy, power, and speaker in, and we’re off to the races again.

AExplorer

Serial

You will need a USB to serial adapter, a null modem cable/dongle, and a 9 to 25 pin serial cable (if your null cable isn’t already a 9 to 25).

PlipBox

Once you have your PlipBox and MiamiDx up and working, it is an excellent way to move .ADF images around to the computer.

Right click on AExplorer on the Amiga, and bring up the information box under the icons menu.

Change PACKETSIZE up to 4096 or larger.

Run AExplorer on the Amiga, and it should autodetect the TCP/IP Stack. If it comes up with serial, your TCP/IP stack isn’t running.

Right click on the Amiga Explorer on your windows desktop, and go to properties.

Make sure the address matches the IP address of the Amiga, and connection is set to TCP/IP

On the options tab, make sure the packet size matches the number you entered in the AExplorer tool PACKETSIZE parameter.

PlipBox and MiamiDx

PlipBox and MiamiDX

PLIPBOX

The PlipBox is a budget ethernet adapter for the Amiga that plugs into the parallel port.

While far from the fastest, it offers about an 8 to 10 times speed increase over using serial. I found an .ADF image that would take 8 to 10 minutes to download over serial (19200 was the maximum reliable speed I could get), would be transfered in about a minute and a half over the plipbox.

The total cost for the hardware was under $20 for the arduino nano, and the network shield.

Constructing the PlipBox

Once you’ve built the hardware, and have the firmware loaded:

From the command line:

copy plipbox.device devs:networks/plipbox.device

 echo "NOBURST" > sys:Prefs/Env-Archive/sana2/plipbox.config

 

My PlipBox would not run with out the NOBURST parameter.

MiamiDx Install

From the command line:

lha x MiamiDx10cmain.lha ram:
lha x MiamiDx10c-Mui.lha ram:
lha x MiamiDxKeys.lha ram:

Open Ram Disk on the desktop, and the MiamiDx folder inside.

Run Install_MiamiDx.

From the command line:

copy #?.key#? miami:

 


MiamiDx and PlipBox

  • Launch MiamiDX
  • Select Hardware Tab and click New:
    • In Select Hardware Type pick Ethernet
    • Enter a name for the hardware, e.g. Name: plipbox
    • Keep Type: SANA II
    • Pick plipbox.device: Driver: devs:networks/plipbox.device
    • Confirm with Ok
  • Select Interfaces Tab and click New:
    • Pick Interface Type: Ethernet
    • Pick Interface connection: LAN
    • Select your hardware: plipbox
    • You can either configure your Amiga statically or with DHCP: Select static or dynamic in IP Type, Netmask Type, Gateway Type. Enter your network parameters in static mode. (You will need to move the slider next to gateway to ‘un-gray’ the box to make an entry)
    •  Multicast: disabled.
  • In Databases Tab select Table DNS servers and add your static DNS server IPs (if you don’t use dynamic DNS via DHCP)
  • Do not forget to save your settings with Amiga+S or Menu: Settings -> Save
  • Now you can go online with your new interface plipbox

You can test your interface is talking with the network with miamiping:

cd miami:
miamiping 192.168.x.x

Adventures In Amiga Land

| October 18th, 2017
Yet another sporadic entry in my vintage computing blog.

I have an old big-box 2000 that I bought some 20 years ago. I finally decided to take it off of the shelf, watch a bunch of Amiga documentaries to get pumped up, and use probably the most interesting & capable machine I have in my hoard.

Viva Amiga!

From Bedrooms to Billions: The Amiga Years!

As it came as a empty boring beige box, I’ve been slowly adding bits and pieces to make it more useful, as I find affordable upgrade parts. Amiga parts are obscenely expensive, especially for the big box units.

So far, I’ve added a GVP G-Force 25mhz 68030, 2 sticks of 4mb ram, scsi drive, retina Z2 graphics card, 3.x kickstart roms, workbench 3.1, and Plipbox ethernet.

The plan is to document how I set up the amiga (for other people and myself in the future):

A New Home

| December 10th, 2016

Retired my 12 year old intel server after years of reliable service.

I bought a used HP ML350 G5 tower, stuffed 32GB of ram in it, a pair of top end X5460 CPUS, 8 2.5″ drive sleds with a random assortment of SAS drives, and some more 500gb 3.5″ drives.
