Bought my programmer a few years ago and used it to make 1.04 tos roms for some of my atari st's. Found it to be fairly easy to use and is a useful bit of kit.
@@RetroComputingReboot In my ST's, I went from 2 x rom chips to 6 x rom chips. I don't know if you'll be upgrading via 6 x rom chips to 1.04, but if you are, I have split the 1.04 image into 6 parts and can email them to you if you wish?
@JohnSmith-bh4zx Thanks John. I'd appreciate that. I've got 4 ST's, a mixture of 520 and 1040 ST and STE's. I can't remember off the top of my head how many use 2 ROMs and how many are on 6. What chips did you use?
@@RetroComputingReboot 3 of my STFM's had 2 rom chips ( in each machine) with TOS 1.02. I used 6 x 27C256 -10 (I'm not an expert but you may be ok using 27C256 -15 or similar) and split the 1.04 image into 6 parts. What's your email so I can send the images to you. If you replace 2 rom chips with 6 chips there are 3 links on the pcb that need solder bridges to be removed from "1M" and soldered across the "256K" bridges, but they are easy to spot.
@@RetroComputingReboot Hi, I don't why but YT seems to have lost a reply from me? But anyway, the Eprom's I used were 27C256-10, but I think you could use slightly slower chips like 27C256-15. If you increase the number of roms to 6 you will need to unsolder 3 bridges on the pcb from the "1M" link to "256K" link (the exact location of these links can vary with the motherboard version) but they are fairy easy to spot though. Let me know your email and I can send you the split 1.04 images.
im glad you explained this , as i have been toying with a purchase to burn roms for speccies , the selling point is that it also checks IC's which means you can save on buying a dedicated tester nice explanation for us older slower users
Great video.. I've been eyeing up one of these for a good while - being able to write my own ROMs for retro kit would be amazing. It looks like the T48 is significantly cheaper than the T56 but does pretty much everything I'd need.. maybe this is a Christmas present for myself 😁
Thanks James, I really appreciate that. I'm glad you liked it. I just wanted to make a video for anyone out there who had been toying with the idea of getting one but potentially put of thinking it would be hassle and overly complicated. I think the T56 is probably only worth the spend if you need a larger ZIF socket or do loads of programming where the faster programming speeds would be of benefit. When I got my T48, I just got the unit on its own without all the myriad of adapters you can buy. I can potentially see myself needing adapters for PLCCs at some point (maybe), but I'm going to be fine with just the ZIF socket for now. The good thing is as well, you can always buy the adapters separately at a later date for what you need. I've got some videos planned now making use of this, so it will be getting plenty of use

Funny you should mention that. I've got some chips on order so I can upgrade my Atari ST's

@@firsteerr I'm glad you found it useful. I e been in the same boat as you have for ages. It's surprising pretty straight forward to use

Can it program 27v and 25v eproms ? That is the important thing.
@@G7VFY According to the specs it can go up to 25v
@@RetroComputingReboot Can it do 2708, 2716, 2516 2732 and 2532 as well?
@G7VFY You would have to check on the Xgecu website. All the specs are there and a full list of chips it can work with
@@G7VFY No not 2708s unfortunately.
