Hi Folks
Would anyone (in UK or Europe preferably to keep postage down) be able to burn the 1050 Rev L ROM to a 2732 EPROM for me? I have a dead 1050 with a bad ROM and my programmer won't write 2732s because it's limited to 18VPP. I guess if anyone had a spare mask ROM to sell that would be as good and I could just change the jumpers.
Happy to send a couple of 2732s your way and cover reasonable costs
Thanks
Thought I'd let you know that, according to the datasheet, the Fairchild NMC27C32BQ only requires +12.5 to +13V for programming. They are also discontinued but still available on eBay.
