I’ve damaged the ULN2803A IC on the output stage of the 8055. Where can I get a replacement (in Australia or by mail order)? Are there any any compatible IC’s. I can’t seen to find any datasheet info on the IC.
You have to use either ULN2803 or ULN2803A. Please check the right housing e.g. Texas Instruments part number is ULN2803AN for PDIP housing.
Here is a link to the datasheets:

Thanks for the prompt response and info.
Please can you advise me where I can buy a replacement IC. Thanks
Your local Velleman distributor would be a good place to start looking for spare parts.
Furthermore, every on-line electronic parts retailer carries these very common IC’s.
Use a search engine.
