Wow, my first computer. Got it when I was about 9. Although mine was a Timex Sinclair 1000 with a wobbly rampack .

You’re welcome

This looks a lot like my C103414-001 board. It has the same IMP chipset, layout is similar only on your board the memory is through hole. On my board, the memory is also SMT. The pinout of those DRAM’s should be the same as on mine, only the package is different. On my board, we’ve removed the 256kx...

Well, I successfully completed a 320 KB upgrade on my 130XE and now knowing that the information is very hard to find I thought why not share my experiences doing this upgrade. This upgrade is based on an upgrade by Scott Peterson with a little improvement to make ANTIC banking work again, as this u...

I’ve been using Digikey for some time now and till now not really any problems. I usually get the stuff I order. I like it, that you can make a BOM on their website, so you can order the same stuff as a kit again,

For parts: Digikey USA: http://www.digikey.com Digikey UK http://www.digikey.co.uk In my case, as I live in the Netherlands: http://www.digikey.nl I mostly order my stuff here, if I order more than €50,- the shipping is free. Only disadvantage is that I have to pay VAT when stuff arrives. They have ...

I have one of those magnifying tools you can put on your head with a light in it. Works for me, I do SMD soldering with it.

Welll, that is something that happened some time ago, I was at home and my girlfriend would come over for the weekend. I had some of that par baked bread with some of that buttery stuff with herbs inside of it, thought it would be a nice surprise.... A surprise it was indeed... I had one of those mi...

This is similar to a 4 mb upgrade on a C103414-11 STFM board. This board has 4x 4 bit 256 kb dram’s in SOIC package (SMD) and one empty bank. All resistors are connected on this board. The one I have, has an IMP chipset so it will not support 2,5 mb of memory. All of the 4 ram chips need to be remov...

I’ve done a 320 kb upgrade on a 130XE, I had to desolder the second bank of ram chips. My solution uses a 74LS158, a 33 ohm resistor and some wire. I used the 256 kb drams from a dead Atari ST.
