Fixed My Amiga 1200's serial port
about a week ago i got down my Amiga 1200 to have a bit of a play with and to see if i could find out what was wrong with the serial port, many years ago i remember trying to wire something up to the serial port and i think i must of damaged something, because i could send data out from the amiga, but just not receive anything, so after doing some testing with my multi meter, i tracked the problem down to a small microchip that connects some of the connection from the serial port to the rest of the amiga, the rest of the microchip was working fine except for the part where the receiving data comes in from the serial port.

after searching ebay, i found the right chip to replace it, the one that was in the amiga had the number MC1489D and the one i bought was DS1489AM, the model numbers are different, but after looking up the data sheet's for the two chips, i found that they are the same chip, just different manufacturs.

i did first try to de-solder the chip from the board, but one of the tracks on the board ended up caming off, that one of the legs of the chip was soldered too, but lucky that track was not connected to anything, so i just left it off, the way i ended up removing the old chip in the end, was to cut it's legs off, using a small disk saw, that way i could remove the ends of it's legs from the board much easier using my soldering iron and not damage the board any more, soldering the new chip on  was a little tricky, due to it being so small, but it didn't go to badly as you can see from the picture.

now i can use the serial port to transfer files to my amiga over a Null Modem cable.

more specs here

i did have 1 or 2 problems with installing a Linux OS (but not with Windows 2000 and XP)

when i tried to install OpenSuse 11.3 it would freeze, after a bit of web searching i found that by adding some switches to the GRUB boot options (nousb nousbstorage apm=off noapic noht nomce skipddc) then the install went fine

the other problem was that OpenSuSE would freeze when the Cap-Lock or Num-Lock key was pressed, also would not reboot, but again after some web searching i found out how to access the Advance Options in the BIOS (System Configuration Utility) by pressing CTRL+A and to change the APIC mode to Full Map that seemed to fix the rebooting problem, when i was in the Advanced Options i found a option named Hot Plug Keyboard, that was Enabled, i Disabled that and that seem to fix the keyboard problem, it still wont fully power down when halted, but that's no big deal.

all in all a good buy i think.

Dysan 360/2A Alignment Diskette (1984)
i found this 8 inch floppy disk in a skip, about 12 years ago, from looking at the instruction leaflet in the box, this disk was used to align the head(s) of a Dysan 360A or 360/2A 8 inch disk drive, in conjunction with an oscilloscope.

My Palm treo 600 (smart phome!!)

i bought this Palm treo 600 (locked to Orange) of eBay (09/05/2010) for just £10+P&P, it was listed as untested (hence the cheep price), with nothing else just the phone, i new there was a 50 50 chance that it might work fine or not at all.

when it came, the first thing i did was to see if it works or not, so i checked it over and the first thing i found was that the battery was none removable, i undid the 4 screws on the back to get to the battery and tested to see if there was any charge left in the battery, luckily there was no charge what so ever (0 Volts), this told me that there was a good chance that the phone had been forgotten about and not been charged for a long time and might still work.

i then looked for some were on the circuit board for some were i could solder on some wires to run it off a fully charged battery i had (i.e from a different phone) that was the right voltage (3.7 volts), i found some points on the board and connected up the test battery, just as i hoped IT WORKS!!.

there are still two things left to do before i can use it:

  1. buy a charger to see if the battery is ok, if so then
  2. unlock it (i did find a firmware unlocker of the net that should work)

click here for some specs of the phone
and here are some pictures i took of the phone so far

Just a quick update, the charger/sync cable came today, the phone is on charge and all seems ok so far.

well as you can see, it works, i’ve unlocked it and debranded it, plus i’ve undated the firmware too

Total cost £13.78

  • Palm Treo 600 £10
  • Sync/Charger cable £3.78
  • Unlocker £Free
  • Firmware Update £Free

EasyData ELF Terminal (1987)
this EasyData ELF Terminal was swapped for the ICL DRS MK2 (see below), it has a 7" screen and a tiny keyboard, i think it use to be used to connect to the Prestel database system, provided by The Post Office, here in the UK.
